Great video best I've seen and been watching videos for 4 hours a day the last two to get a understanding of how to determine shock spring and settings for base tune based on the rider
The videos feels natural to me now. Although I missed a few videos. The MC garage is back to its full form of quality I remember it not saying it was bad just feels like you formed into the previous host style with your own same with Adam for MC Commute. Great job Justin!!
Nice 👍🏻. I know this and been thinking I should do it for about 30 years. Haven’t yet lol. I love how you don’t take 12 minutes to explain this. I don’t need to know what you like or what you ride or bla bla bla. Nice video mate. Good job 👍🏻 gave you a thumbs up 👍🏻.

Thanks a lot! I get misunderstanding on 3:41 >50 sag needs softer spring?
4 года назад+3
If the spring is soft, you need to add more preload to achieve desired rider sag. Adding preload removes free sag. Using too much preload on too soft spring makes it initially hard but hasn't got enough support on hard hits. Less preload on harder spring is better than more preload on softer spring.
Do these rule of thumb still apply to supermoto use? Just got back into bikes and want to properly set up my 17’ wr450 supermoto. Not sure how to adjust the suspension as it won’t be off road much if at all at least till after winter here in Illinois. Any help is appreciated. Thanks!
What if I am constanly changing luggage and gear? Somedays I'll carry alot of gear and weight and Sometimes I'll just ride with small back pack on. Riding a fe 501s.
Knowing my suspension is from the factory and its 6 years old, what are the chances of a 260lb rider getting the sag right? I asked because my numbers don't come near your recommended 100 mark but I'm sure there's a lot more other factors that play into it. There's nothing about how a persons weight affects the sag or if there is I'd like to know, what good would that do if my suspension is whacked right. 2014 Honda XR650L front forks lowered 3/4in to accommodate the 19 in wheel
I weigh the same and owned that exact motorcycle, maybe you have tried this, not trying to be a know it all, but I found for dirt riding to definitely change the tires to mid to soft range and lower the air pressure for off road 15 front 10 to 12 in rear and traction comes alive, probally not what your trying to achieve, if you do highway you need dot tires and higher pressure. That’s a awesome motorcycle, I bought mine in 2008 , don’t worry I fight this whole sag thing also. I have a 2009 rebuilt crf 450r the thing seems like it’s glued to the trail, get on my 450 ktm xcf-w and it’s squirrley don’t have the confidence but it’s new and the tires are super hard.
Guys, thanks for the video, it's very useful! But I wanted to deduce the determination for the word sag. is it possible to call a sag a range? Sag as a manufacturer's recommended suspension compression range? A static sag is from 30mm to 40 but its a range, it is a recommended range and for a rider sag also is a recommended range. So is the sag a range first of all?
So if someone is over 6ft. & 240 lbs.Wont pre-loading/compressing the spring, cause a loss of needed seat height, reduce travel & make it bottom out even easier by making the stroke shorter? Can you take the sag out by expanding the spring rather than compressing it?
You aren't going to lose suspension travel from additional preload unless you are using a spring that is way wrong for your application(spring is too short, too many coils, or WAY too soft). The spring coils should never be the part of the suspension that bottoms out, instead that should be the foam/rubber bottom out bumper around the shock shaft. For the hypothetical too short / way too soft spring that would shorten the stroke, it would only shorten the bottom part of the stroke, so your seat height would be the same, and ground clearance would actually be better since it would bottom out higher up in the stroke. It might also make your spring explode too, but your ankles, wrists, and spine would probably explode before that.
Everyone instructing on sag always wants to give definitive numbers. Like “sag should be 100 mm” my number is going to be different depending on what points i took my measurements from, therefore, you should be instructing what percentage of your full stroke should be used. So should your race sag be 2/3 of your full available stroke? Thats the info im trying to find out. But everyone always wants to throw a number out there that i only relevant in their situation
You are overthinking it. Long as you use the same points to measure all will be good. To set the point to measure take the distance between the swing arm pivot and rear axle, now match that measurement between the swing arm pivot and your bodywork, that’s the point you should measure at.

When you do your initial measurement and got 600mm was the shock fully extended?
Nice video - to the point and clear. I have seen probably 20+ vids on the subject and this is top class. Thanks.
Exactly what i wanted to say... Dude they talk 10-20mins and i didnt understand shhiet. This guy made it in 4 min.
If anyone wants to learn about Jesus Christ reply
Best video on sag by far. I’ve watched a lot of videos but this one is top tier. Short and simple

Great video. On point. Not complicated. Great advice. Super easy.
An american saying: "measure in mm"...there is hope :))
No, he will move to Europe one day 😂
We weigh some stuff in grams to if you ask the right people lmao
Hey man, some of us paid attention in school :)
Nice 👍🏻. I know this and been thinking I should do it for about 30 years. Haven’t yet lol. I love how you don’t take 12 minutes to explain this. I don’t need to know what you like or what you ride or bla bla bla. Nice video mate. Good job 👍🏻 gave you a thumbs up 👍🏻.

Very helpful thank you I'm new to dirt bikes and I have way to much sag
Clear and quick. 10/10

Great video nice and simple instructions
thank you for the awesome vid, do you think I can use this configuration for Supermoto? 100 mm rider ; 35mm for static
thanks for the no BS video, so many on here that are a waste if time
I got a yzf250. 5’11 225lbs. Aside from losing weight lol what can I do so the seat stays up right and doesn’t sag to much? Larger spring?
You need a stiffer spring!
I get it. Sag, measurements...but does more preload increase or decrease rode height?
Increased preload will increase ride height
Great, but what about the forks? Mine are 0 sag. Is that normal?
What if I am constanly changing luggage and gear? Somedays I'll carry alot of gear and weight and Sometimes I'll just ride with small back pack on. Riding a fe 501s.

What about the front fender. My front tire make contact with the front fender when a go through a minor hole
So do I measure between fully extended and with rider on it. Or, between esthetic and with rider on it?
Thanks. Helpful
Is there is a front fork sag adjustment on dirtbikes?
Should ADV riders set up their bike using the street bike guide or this dirt bike guide?
What should the race sag be for a 220lb rider on a yz 125? I have asked several people and i get answers of 104mm to 112mm .
Thanks
108mm
106-108

I need to check this. I'm 5'10, 215lbs but I can barely touch when I'm on the bike. Kinda scary lol
Thanks!!!
Very helpful
Will a spanner wrench work as well?
this is very usefull video...
Well done
Hii... And how about the setup of the fork... How deep i should push itnintonthe forkclamps
You didn't take pictures did you.. Look at pictures on google. or where the top cap threads start is a good reference.
Bravo 👏

How about the front? 😊
my bike in quarantine ..
I can’t move my jam nut does any one know what to do
😎👍👍🥇🏅🏆as always!
None of these videos explain why they are measuring in inches and talk about mm. Makes the process more confusing.
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻❤️❤️❤️❤️❤️❤️👌🏻👋🏻🇩🇿
I wonder if a Chinese bike has this adjustment?
I have a Chinese RXB250 and it's adjustable
1:40
American Europeans !!!!
Less of this and more of Adam please
Are the numbers the same for front?
Also, if you have a progressive spring, these numbers are very different.
