- Contentious topic, eh? Some say it's best to run an engine hard for the first 1000km; others take it easy during the break-in period. Here's how we do it.

"It moves oil to the oily partsof the engine." That's the kind of sage advice I subscribe for.
Was that advice, or an observation?
@@samshambles391 it's part of the get the engine running advice, that being to run the engine for a bit to get oil to all the oily bits
With F9, it's all about the attention to detail that makes this the best motorcycle channel going...Atticus Finch's court file...outstanding 🙌
Just remember that while that is true, it doesn't warm up and get all parts right. A short moment to get oil around the engine is fine (which is only about the time it takes to put on your helmet and gloves), then ride gently until the engine reaches operating temperature. That's generally enough time for grease and oil in all other moving parts (ones that may not get heat idling, but actually moving to get to a good running temp before giving the bike a bit more go.
The sand paper metaphor was very artistic. You don't get that kind of creativity from moto-vlogers.
Best representation of how to properly break in a new/rebuilt engine (mainly a stock or street engine) and why to do it that way. Of course race engines or blue-print builds are a little different. Tighter tolerances, types of rings, types of bearings, and even types of plated cylinder walls, cylinder hone,can change the break in procedure as well, but that's a whole different topic.
Right now in 2020 There are to many cinematic moto vloggers.
@@ajinkyathorat7502 Really? can count them on one hand.
@@ajinkyathorat7502 Fortnine. Schaaf. ...???? Who else? And i think they're both brilliant.
Lol way to overtstate it
I used to work in aviation, and i remember watching a guy fly away from the overhaul shop that finished a major on his Beechcraft bonanza ( io-540). The shop owner who was standing next to me commented that there went an engine that would be back under warranty. When i asked why, his response was that the owner/pilot hadn't used full power on takeoff, probably thinking that he was babying the fresh engine. He then went on to explain the very same things about the relationship between cylinders, pistons, rings, thermal hardening and the break-in period that Ryan did, but without the benefit of video aids. Well done Ryan
finished a major what
@@debaronAZK major work, you numbnut...
@@debaronAZK a major overhaul
@@ok0_0 duhh
I wasn’t aware that nowadays we could get video aids.
We learn something new every day..
Your story telling , cinematography and editing is just so eagering to just keep watching your videos
Eagering is not a word. Earnest would be more appropriate.
I feel like it's a little too much.
‘Engaging’ would be the appropriate choice.
He is not doing it alone. It is a whole production team.

"...and so that anything that's going to break, will break under warranty."
Now that advice is refreshing to hear coming from a company, that's why I respect and trust FortNine. You would never hear advice like that from most of the others in the industry, 👍 to Ryan (and the FortNine team) for keepin' it real.
Right on, It's a company for the people rather than the industry, in a world where it's so lucrative and tempting to betray your own and be swayed their way
Its unfortunate that the experience isn't universally shared. Ryan makes fantastic content. Fortnine customer service however, encourages people to go to their local brick and mortar to try on equipment and clothing first when you are going to buy something Fortnine has on sale. They don't do exchanges so if you want it for a price, you either buy multiple sizes and return everything or you have to try it on.
Aenslaei They do exchange for about $7. Small price to pay. FWIW though, I've always bought helmets at local shops at better prices than Fortnine.
@@Aenslaei so nice to be living in the EU. ANYTHING you fucking buy apart from food can be returned to the store within two weeks, no questiones asked. EU policy against scumbag companies
@@Darkest_Soul_187 Can't speak for the whole EU, but in Germany the legal regulations for returning goods are part of the Fernabsatzgesetz (mail order law?), so they apply only for stuff you buy online or by mail order. There is no law about returning goods in real (brick & mortar) stores so any "right" of returning goods in these stores is a voluntary service of the shop.
Finally, someone talking sense on the subject! This is how I've been telling folks to break in a bike for ages and almost always get looks of disdain.
Thank you Sir! This video is 5 years old, but still going strong. I keep coming back to this video everytime I buy a new bike to refresh my memory. Tomorrow its the Ducati Streetfighter V4S. ✌️
Applies to cars and trucks too
I always get mad when I notice how low your views are when compared to other channels who provide shitty content... The amount of work put into each video looks huge. Keep it up, you will get a fair recognition some day!
It's bearing fruit
"Any experienced rider is inexperienced on a new bike", a true statement. I crashed my new bought Hayabusa in the first 1000km even though I ride motorcycles since 2007. I still own it: a unlimited 1999 model. It was a small crash but still... it was avoidable as a vast majority of crashes are. Of well! Take care out there!
Can you show us how to un-break an old motorcycle? Thanks.
meme master 69 just put new shit on until she’s not hurt
🤣🤣🤣
I was a bit concerned about the break in period, but I've actually been doing all of this with my new bike by accident. I've only put a little over 200 miles on it so far and I've been cruising between 35 and 50, taking off in the straights and hitting a few twisties before either stopping to grab a soda or something to eat for 10-15 minutes.
Interestingly enough my brand new Yamaha Bolt owner’s manual described almost the very same break-in… varying RPM, don’t lug the engine and don’t go for sustained high rpm rides (highway). FortNine’s videos are always spot on. I would think the manufacturers know how to break in the bike so the customer gets a longer, lower maintenance life from their product.
I have to hand it to ya man you really make some quality videos. Keep up the great work brother!
500th like 🥳
Is it him making the videos or is he just the figure head for Fortnine?
@@mattsupertramp6506 as far as I know it’s pretty much him and one other bloke.
Look, it's the guy who pimp his girl on yt
@@MrNicklasson87 he has a team but what a personality
Excellent video. I broke in my bike this summer and the service mgr told me to ride my new bike like I normally would. That is, 1/4 throttle, 1/2 throttle, 3/4 throttle, and full throttle in every gear with multiple stops. I varied between road and highway so I had to make stops at traffic lights. I made stops to tap up on gasoline and for dinner. The main thing is not to ride at a constant speed in one gear.
This is what I did. Works Great!
I just figured break it in the range that I ride. Able to do traffic in city and a few twisty backroads home. All the range of speed is involved in my commute. With one perfect pull off road by a car rental place with markings on the ground for u turns practice. And year round riding with extreme heat vs cold. Had it 2 weeks and up to 289 miles already from 8 only when I bought. One oil change done, spark plug & fuel/air hoses changed from factory, getting ready for next round. It sat for a few before I got it, they never rode it ,ever..😢 so being super vigilant will help I hope. These videos are all very helpful and entertaining without being lame IMHO. I have learned a lot. Thank you, years later, it's still helping people.
FINALLY I hear something that makes SENSE, thanks for this men, Ive broke in 3 bikes so far and I was never sure if I had to take it gently or savagely on the engine. This is the most sober advice, and I know it'll help a lot.
It’s nice to watch these videos after watching cyclecruza videos...

Still can't believe how high quality these videos are, glad I found your channel and am incredibly surprised at how small your subscriber base is. Cheers for all the videos!
5:53 Holy cow! how many shots did that timelapse took? !!!
Amazing job, pure quality content in this channel, love it !
It's not a time lapse. He just jumped 4 times with different outfits, shot with a high fps, try to recreate the previous jumps using the same path and speed, right cutting at the right time, and then stitched the videos to create an almost flawless sequence.
Edit: Had to edit my grammar in case another grammar Nazi comes. My grammar was f'd up because I wrote it while drunk during liquor ban and English is my 2nd language.

I didn’t notice, too busy looking at the trees. Thanks for the point out.
Just discovered this channel last week and is easily already one of my favorite channels.
Exactly how I did the engine break in on my last two motorcycles. Finally someone did a balanced video on this :-) thanks Ryan!
Tho for how long do you break in??
@@businessrooster7272 id say 600 miles which is usually the first oil change
@@businessrooster7272 depends on bike, Im breaking in 2 strokes for like 300km
I simply love this channel. It always covers up all posibilities and thoughts without being afraid to trigger someone.Also time flys by while watching your videos, cause they are just so entertaining. Huge respect guys, excellent quality, amazing presentation and valid opinions.
Love from east Europe.
P.S. Sorry for any mistakes, my english are not the best.
One legend you are - Big fan of your in just 3-4 videos, high-quality shots, super knowledge, great overall experience .. Way to go buddy !
Perfect timing! Picking up my new BMW this week (but bought it last October). Those are great tips. Love your videos - my favourites out there for real reviews with integrity.
I just bought my fourth bike (2019 ZZR 1400) and I'm glad someone finally talks sense. You get a subscribe!
Excellent how to video! Still breaking in my 2017 R1200GSA at the moment. Will apply this immediately. Keep up the videos!
Finally. A nice balanced and factual version of everyone else's passionate fantasies about how two pieces of metal wear together. I've broken in a handful of new bikes the same way. Although my method involved a bit more vigor, with heat cycles and cool downs of course. Oil changes flush out the fines and away we go. Never ever had a single issue with any of them. All ran exceptionally well.
One note: the plating manufacturers are coating cylinder walls with these days are EXTREMELY HARD and DURABLE, and don't take to mating with steel rings real thoroughly unless sufficient force is put in the cylinder. The longer the user pokes along, the more apt they are to glaze (heat treat via. mechanical friction) microscopic ridges and peaks in the rings which will ensure they never shear and mate properly.
I find myself watching some of your videos multiple times, that's how good and informative they are. I'm watching this one for the third as I'm buying another new bike next month.
here i am watching it again with my new bike
New to motorcycling and motorcycling interest. And your videos Ryan, are staggeringly awesome. Crisp, informative, not lengthy, and word efficient. Simply phenomenal.
This is also the correct procedure for gearbox break-in. Great Video!
Holy shit man this channel cracks me up 😂 I’m supposed to be asleep right now but I’m binge watching all the videos.
These videos age like fine wine
Everybody including the mechanics keep advising me to keep it under 4000rpm for 2 whole months .You are the only one who said otherwise and I trust you .Plus your visuals are amazing
Same man. Got a ninja300 a month back and have been limiting myself to 4k. Now I'm confused whose advice to follow
I suggest you follow fortnine's advice even though I'm not sure about riding at high rpm for 10 minutes since mine is a cafe racer
Ninja probably won't have much issues
Depends whether or not you trust the engineers that developed the engine, and the mechanics who fix the engine. Or some guy on youtube. I enjoy Ryan's videos, but his method isn't exactly scientific.
Great advice! Just got myself a brand new Honda nc750x, I've had bikes for 10 years and this is my first new one, thanks for the advice on breaking the new beast in! You always make quality watchable and relatable videos! Cheers from Ireland, Claire 👌😊
How has it treated you?
This week I am in the same situation; I got a new Ducati 1260S, and I'm totally agree with you: " experience bikers in a new bike, get inexperienced ". Good videos
been lurking your page for a month. the process we use to break in RC engines is roughly the same. avoid low pressure, avoid overrev, dont baby, but dont stress. since all engines are basically identical your logic is sound. got a new sub.
This video is so well shot, it's like the older Top Gear of the motorbike World =P
Great stuff.
Ive been breaking in my bike this way without even knowing this was the correct way to break in the engine.
See its my first bike and its not a slow one so im slowly learning and getting used to the bike.
I take it out on the town streets and go from light to light then climb up on the highway for a few miles while dropping the hammer as i enter the hwy.
Then i exit the hwy and come back towards town and do some sprints on the lonely service road with no traffic.
After 30 min or so i come home with a big smile on my face and call it the day.
Thanks FN good info especially about new and slickery tires. Breaking in a motorcycle engine and other moving components is hard work, I've done it three times over the years and it is a constant in life, up and down, red line occasionally, no lugging, and riding in an area where you won't piss off the other traffic as I go about my routine. Hard work requiring conscientious attention to "the plan". Best experience was the first, '75 750 BMW, I swear you could feel it just busting out to get to the next rpm allowence. Quite an experience as the engine responds to what is allowed to do. I use a different formula now than back then but essentially the same as FortNIne lays out, for the first 1000 miles, I'm not sure how many liters of beer that is in Europe.
The production value is amazing on all your videos. This one especially
Brave guy taking on such a controversial topic. I totally agree and have followed that same strategy with cars for years- never had any excessive oil use until over 100k miles. Good advice and easy to understand. I respect your opinions because you have much more experience than me, and seem to be thoughtful about every topic I’ve watched. Thanks!!
100k, as in KILOMETERS I'm hoping :)
This is by far the best video and best information I have heard on this topic. It seems there are many people at both extreme ends of the spectrum on how you should break-in a motorcycle, but this video does a great job of splitting the difference. It explains a few things that I don't hear touched on very much and does a great job turning that into a logical and compelling argument for proper break-in (as well as making good, well informed points on what constitutes improper break-in!)
The middle way is probably the right way, stick below 50% revs for at least a few hundred miles without lugging the engine.
@@chrissmith2114 So is it best to usually go at 3-4k rpms and occasionally go higher revs so that the engine gets all the 'feels' ?
I’ve watched this before. Watching it again on this beautiful Sunday as I’m about to get my new bike out! Bought it this winter and it’s waiting for me.
I am glad I found your video on time !!! I am picking up my new Ducati super sport S tomorrow. Thank you for all the great information.
Damn your production value has gone really high. Same great info in a new package.
"... and anything that will break, will break under warranty." That cracked me up, great closing statement!
Got me right in the funny spot too :-)
Just what I was looking for! I'm picking up an F900 XR tomorrow morning -- and of course left researching to the last few hours. Thanks, man!
This is probably the most well-produced motorcycle channel on RUclips.

@@nathanielyoungman4454 it's the best thing that ever happened to me. I've put 20,300 km on it so far and my favourite thing in the world to do is ride my bike. I even started a gang called the delightful strangers 😂, there's five of us so far
Just The Best Break-In Video Yet on RUclips. Best Ever. Honestly.
Love from India @Fortnine
I'm glad you went into this I've sold motorcycles and worked on them for 50 years and I never could argue with too many people that say you don't need to do anything to break in an engine which is the stupidest thing I've ever heard of but anyway thank you..
I don't ever buy a new motorcycle. Always prefer old but had to watch the video cuz fortnine stuff is some quality stuff.
Asad Siraj the motorcycle s I want are brand new models that just came out so I will take that over used
Very good points. To each his own for sure. Reason I love used is I switch out a lot of parts anyway to customize the vehicle and I enjoy working and learning on them.
Asad Siraj yea if you are going to do that , then I do understand you.
I think if a motorcycle is not good enough stock, then its not worth buying. But thats just me.
At least we both love working on our motorcycles!
Daniel B i can see that with off road bikes but I'm looking for a more street oriented bike as my next bike. Oh my profile pic? Man I need to update that. I was planning on getting that as my first bike but I ended up getting a 01 ninja 500r!
Stephen Hartley Brundrett hear you man. Also there are some bikes that are very special like the 05 06 gsxr 1000. I bought my dream project bike being the 05 R1 when they had great horsepower for a fraction of what its worth.
This is motorcycle Top Gear, I love it.
Coming across your old videos, and I love it!
Alright I love this man how he delivers his humors in motorcycle 💓
I think I will my first NEW motorcycle in 2 or 3 Years. Tomorrow I'll get a Yamaha YBR 125 Custom! I love it!
One day I'll get a new motorcycle. One day.....
vzda123 don't do it! It is addictive once you do
Just got my first new serious bike in november - gotta say it's a very pleasant feeling, when you know that nobody sat on this thing, nobody raped the engine, and, needless to say - it's worth to buy a new bike just to peal off that protective film off of the brand new dash.
Сергей Метельский 👍🏽😎 virgins...
Hope you get it already
One day usually means never 😐
Very impressed by the production !!! Great job guys !!!
The quality of these videos is amazing
The factory has usually test ran your new bike on their dyno. I think they may bring it up to redline without a lot of RPM varying. It does get a very long cool down cycle.
I got a good kick out of the "Evils of Capitalism" and other contentious topics section. I dig this a bit more than the full-on skits becuase it's funny while still being an informative format. But, literally everyone else seems to dig the skits and I won't lie and say that they aren't imaginative and well done. 'Cause they are, especially the Bill Nye themed invisible riding one.
Also, WOW, I did not know anything about the piston/piston wall thing, and the sandpaper analogy is great like Lawrence said. That's incredibly informative, I'll have to keep that in mind.
Man I love your channel. Your videos are so informative and beautiful to watch. Keep up the great work man!
Very helpful, love your filming style. Thank you.
Do you recommend changing the coolant very early along with the first oil change?
to remove any contaminants
Hey Ryan! Absolutely love your videos and you commentary! Just wanted to know whether these rules apply to all kinds of bikes across various platforms and manufacturers? Or just top of the line German engineering... And I've also heard erratic hard riding has an impact on the fuel efficiency.. your thoughts?
Your fuel economy over 1000 km or so is minuscule compared to an engine replacement outside warranty, so it may be worth varying your speed.
Love this guys reviews! Great job mate. Have now watched a heap of your vids!! Straight to the point and no bullshit! Just how I like my reviews! Keep up the good work 🚴♀️👍
Nice logical and easy to follow explanation. I also use this method of varying the revs without loading the engine but see so many riders on forums fail to grasp this concept. I’ll use this video to explain my point of view. 👍
but you want to load the engine. Literally what he is saying
Great video! I appreciate the explanation. How many km does your method of varying the power and cooling take to do the break-in? I've seen 1000-1600km for break-in periods on other bikes but your video seems to suggest your method would only take maybe a few hundred km.
How long would you let it cooldown?
Para los que hablamos español, "braking period" sería el periodo de asentamiento o "despegue", ¿sí?
someone who is talking real sense about motorcycle engine break in, cool illustrations 🙏 👍
You make the very best instructional and informational and entertaining videos out there. Thx, you're amazing.
Manual doesn’t say to ride gently. It says to avoid full throttle acceleration and hard engine breaking. So just a normal ride for most. The video is a good summary of advice from forum “experts”. The procedure demonstrated won’t hurt, but it looks and sounds like a spell to me.
Aleks Nestserau For most ducati's it says to stay below certain rpms, not specifically redline.
For my z1000sx it said to go under 5 rpm for the first 500 kms and under 7 for 1500 kms.
On cb500f it was something like under 5 rpm for 1000 kms.
Same thing with the cars.
Aleks Nestsera
Yep. For my Scrambler, I had to stay below 6k rpm for 600 miles, and then below 7k till 1500 miles. It also said to vary the road type to hills and valleys like Fort suggests.
Cool story Thgt Ggyh. I'm sure the dealership laughed at you while they counted your money.
You said vary rpm well above lugging (low) and well below redline (high) and that seems good. Also I would add vary load from half throttle to full throttle for short bursts to apply ring pressure while allowing cool down between bursts. Look up "motoman engine break in" to see why (if you have not already).
Excellent video! Reasonable treatment of a contentious topic, entertaining, and easy-to-understand explanations. Got a new subscriber here.
Ryan this was the best video that I ever seen by a motorcyclist especially the jump while seasons pass it was awesome keep up the good work
From an automotive engineer and test driver perspective, you said 4 wrong things according to my experience testing vehicles. First: dont EVER let your engine idle for more than 2min, let alone 5 and let alone a brand new engine. An idling engine does not create oil pressure, and when an engine is running on low oil pressures, it creates heat spots. Now imagine the "heat spot" a brand new engine will create at the tight rings idling for 5 minutes in a cold day. Second: buying in november. Preferably you never want to break in an engine in cold moisty weather, like the one in the video. The (slight) condensation spots that is created within the parts can cause either overheating and/or overcooling and crack materials with different heat expansion rates. Third. Dont do figure 8s to wear in tires. Tires wear-in with temperature, pressure and inertia. One should pump the up the pressure a little more than you would usually ride with and just go out on a sunny day and ride some speeds, hard breaking and corners. Dont worry tires now a days arent "waxed" anymore, you wont crash on a sunny dry weather. And the tire needs that higher speed inertia to sit the wires properly in place. Fourth. What you do NOT want to do when breaking in a new engine is the constant "on and off/hot and cold" cycles like you mentioned. A new engine still needs to "sit and fit" all its components, and that wont happen properly if you constantly let the engine components heat and cool all the time, because different materials and parts sizes/shapes have different heat expansion rates, and if you keep messing around with those expansion rates by heating and cooling it all the time, you might create scratches or even cracks. Theoretically the best way to break in a motorized vehicle is to turn it on and run it with smooth throttle (never full throttle) across all rpms and gears for a veeeeeery long time. Hours. Hundreds of km/miles. And after the first oil change you really shouldnt bother anymore....oh, and preferably you should break in an engine using the best possible quality gasoline you can find, that helps the spark plug, valves, rings, injectors and exhaust/cat to break in properly as well..
...cold days also impact the mentioned heat expansion rates. A very cold engine metal is a lot more "compacted/contracted" in a cold day than a hot day, and expanding that material all the way up to working temperatures might create cracks or scratches. About the low oil pressure thing on point number one: to understand more the theorie behind oil pressures, please watch a "cold day idling" video from a channel called Engineering Explained. That dude explains very simply why idling for 5min is a bad idea. Also, believe it or not, some lab testing we performed at the university showed that, even from dead cold, a piston hardly ever takes more than 20-40seconds to be at working temps. (Gasoline high comp engine; this result does not apply for turbo or diesel engines).
Well put.... I will put that in mind 👍
Good stuff
Basically, do nothing what the video said.
I would still argue that there's more to it than just fuel wash and heat spots in the cylinder. There's also the simple fact that until the engine is warm, nothing fits right. There'll be play, and play is bad. Letting it idle longer allows the heat to permeate the block and things can expand to a more reasonable fit. Bear in mind I'm no expert, but that's how I see it. I'll continue to idle my car for 10 minutes before leaving for work for now.
6:06 And just so anything that's gunna break, will break under warranty! Lol Too Funny
Great vid! Last week I bought my first all-road/tourer/mid-range and the safe place to try out my first ride on it was rush hour traffic in a Filipino city.
Picking up my new rebel tomorrow. This has helped a lot, thank you!
So are you filming these in BC now? Nice work y'all!
it looked like he took a break on cypress view point
Just once I’d like to see a “how to break your bike!” video!
I really enjoy your videos. I'm thinking of getting my first bike, it will be used if course, however when I do decide to get a new one, I will come back to this video.
Good job.
As taught 60 years ago and currently. Applies to all engines . Don't forget to change oil early during break in . Break in all moving parts , U2 .
I see you are getting typical Vancouver weather....
Can we get a motorcycle stand comparison video? Would like to see your thoughts on some of the various options
Okie dokie. ~RF9
Really like these videos, and its nice to hear someone backup what I was thinking.
This video is worth watching. Thanks FortNine
Much as I like your videos, speaking as an engineer I have to disabuse you. Each piston will have been honed to its bore at the factory, so it will basically look after itself (even at idle it is going to be moving very fast), but there are other more important parts within the motor and gearbox that need running in, various shafts, journals, bushes, and bearings. Whilst they will have been assembled with some precision they won't be entirely true and running the motor hard initially can and will turn them oval, which is bad news. By hard I mean slogging it, giving it full throttle, or red-lining it. A gentler approach is needed to produce a smooth running and strong engine. A gentle running in starts very gentle and gradually puts more work into the system as it aligns the components and loosens them up; rate of work is power, watts or horsepower i.e use less power initially, gradually increase it the revs over about 1000 miles.
That is what the video described.
Pretty much. It is best to follow the owner's manual, specifically because the bike has undergone rigorous testing before release and just about any and all conditions have been vetted. It's hard for people to understand this who aren't involved in actual product development. Hours and hours of testing, from full on race speeds to continuous "normal" riding has already occurred, not to mention actual in traffic riding. These bikes are pulled apart to see what revisions need to be made and then retested until the final product meets expectations. As far as liability goes, the company can be very specific in it's language to avoid any lawsuits. In other words, it doesn't have to say to ride gently. It can say to ride with variable changes in revs from x rpm to x rpm and for how long and speeds etc. They can include disclaimers not to ride higher than the speed limit and so on. They don't. They don't because the owner's manual is giving the properly scientifically vetted (ie backed up by real data, not opinion) procedure to ensure the bike will break in the best way for durability and to meet performance characteristics.
To put all this more succintly, the manufacturers WANT you to get the best from their product. Their reputation is on the line and that is important to them. In any are in doubt, why then does everybody quickly trust and suggest following the owner's manual for service intervals and maintenance requirements, yet take that one part about breaking in the bike as somehow......in error?
scientifically vetted? Citation needed.
I usually hear either "Engineers redline the engine long before you get it to; Manuals are written by lawyers" or "Do what the manual says; They wouldn't lie". Your response is somehow both. Hah. My manual's wording on breaking in is impossible to follow in real-life, btw. I hope most aren't so obviously bad.
As far as science, the only youtube vid I've seen science quoted is:
ruclips.net/video/Pxj6rO6KxHw/видео.html
Not quite, I'm afraid F9 was taking it way up the rev band long before the motor was ready for it.
Any new engine takes about 1000 miles to run in, it's a gradual process, the first 100 miles are critical whilst the motor is stiff.
The manufacturers do tend to break it down into steps to simplify the process but it should be a smooth gradual process of gradually putting more and more work into the engine, a lot of it is feel. and backing off when the engine doesn't like what you are asking of it, usually by vibrating more than expected or struggling to deliver.
Citation? I'm a physicist-engineer, donkey's years ago I did the thermal properties for Concorde's brakes.
Mech-eng is something you learn by going to college and spending a lifetime doing and learning as a job.
No, engineers do not red-line the engine for you; that would most likely break a new engine. At best the engine has probably been run up to make sure it doesn't seize up.
Yes, you will find bits of metal in the oil during running-in, that is parts being worn into shape. They probably will not be from the piston, rings or bore but from shafts, gears, bushes and bearings. And why it's a good idea to change the oil and filter several times during the initial period even if the book doesn't tell you to do so.
A piston has to be honed to its bore, so that is done at the factory. At typical idle, the piston will be shuttling up and down the bore about 35 times per second, that's pretty fast. The piston may not need gentle treatment but the small end does.
When an engine runs it pulses with each piston firing obviously, which will have a hammering effect on the components. If we put too much work in before the components have bedded in and are running true then it is going to knock them oval. Once that happens it is never going to be a good motor, it will probably vibrate badly for the rest of its life, and be down on power.
I've seen like every vid on this channel
Do you really need that "like"?
Like no way...
very well made video - very cinematic. Good Job!
That was so beautifully made. Thank you so much for making it so easy to understand. 🙂
I find the break in period usually involves losing a few tassels on the hand grips.
Im okay with that.
Wait. We're not taking about the same Tassels, are we? 😑
I'm so dumb. I literally sat here waiting for him to bring up "how to brake in your new motorcycle" lol I didn't realize the title said "BREAK" not "BRAKE" 🤭
Best motorcycle videos on the web.... thank you!
As about as good and concise info on Break in period as one could wish for..Nice Video Ryan.
