400€ Aprilia RS 125 Tuono Two Stroke build Timelapse - from start to finish in 12 minutes

- Servus and welcome
This Aprilia RS 125 TWOSTROKE motorbike was forgotten in a barn for more than 10 years. It was put there because the ROTAX 122 engine didnt run anymore. Then it got partly disassembled to find out whats damaged but the owner got up. And thats how I picked it up.
First it needed a big WASH, then I started to dismantle it and remove the engine. My hope was that the cylinder foot gasket was damaged but the rest ok.
After the whole engine was disassembled the disaster bike got expensive. With many new parts I repaired and put the nice engine back together. Afterwards the carburettor got inspected and cleaned.
But did it start? Anyway, the bike got completely assembled for the grand finale.
For details of every step and everything explained check part 1 to 6 on my channel.
PART 1:
• Aprilia RS 125 2 Strok...
I hope you enjoy my video and it helps you to repair your own stuff - because thats my intention!
Thank you for watching
Thank you for watching! This project was a ton of work but especially editing this last video was a lot of fun. I hope you enjoy it!
Great job I also wanted a rs when I was a teen and finally got one mine was is in very bad condition
My rs was literally older than me
Nicht schlecht. Schön zu sehen, dass sich mal jemand um eine TUONO anstatt um eine RS kümmert. Viel zu underrated das Bike. Sowohl die Neue als auch die alte.
Thanks for the video. On my Rotax 122 there was a 0.2mm washer between the left crankshaft bearing and the engine block. I'm not sure yours have one. But if you leave it out you can't feel the lateral play because the bearings are new, however after a few miles that play might come back as the bearings and crankshaft start to adapt. You might want to check that out on your next rebuilt, you don't want any lateral play (or max 0.1 mm) of your crankshaft
Hi greetings from the Republic of San Marino. I have one as this which was gifted to me, I'm so lucky. can't wait to start the restoration. It has 40000km all original, sat under a cover for 6 years.
Wow you are lucky. I hope you get all parts to your location, have fun with the rebuild.
@@bikedogtor1663 yes, living in Italy it's not difficult to get them
Hi there. Great to see someone working on an aprilia rs 125 2stroke. Excellent. I'm working on mine at present so I'm sure I'll be contacting you in the near future. 👌👍
Thank you! May part 1 to 6 help you with everything in detail. Dont hesitate to contact me.
@@bikedogtor1663 thanks dude
400 is a very good price for a Tuono even it wasn't in the best of conditions. For the same conditions I don't think you can go lower than 1000, 1200 euros for an RS, particularly here in Italy as it is still one of the favourite bikes, also for collectors.
Today things are much more expensive. I bought one RS 125 year 2002 with engine just rebuilt for 750 euros about 12 years ago, and I was stupid enough to sell it for 1000, even though I had run over 60.000 km on it, but I always kept it in mind conditions (it had a few minor scratches but that was it). I've just bought a 2007 model for 1800 euros, which might seem like a lot, but it comes with Jolly Moto 107 exhaust, VHSB 34, Gubellini rear shock absorber fully adjustable and some other extra things like aftermarket rear view mirrors, indicators and so on, plus all the original stuff (except the PHBH 28). I might make some videos. I haven't touched it yet, I might start doing something on Sunday. It hasn't been used in 2 years so I'll start with carb cleaning and other basic inspections and see if by replacing the battery fluid the charge is acceptable, otherwise I'll have to buy a new battery, and I'll probably go for those extra light ones, every kilo you gain on this bike is worth it. I find your channel useful even though I've rebuilt this engine at least 4 times already and at least 30 other two stroke engines, it helps me remind me of a few details and you use some interesting home-made techniques. A useful tool for these engine is a torque wrench, particularly for the cilinder.
man i reaaaly aapreciate content i know probably somebody mentioned it but when i see somebody smashing steel bearing in aluminum casting with a rubber mallet it makes me reconsider buying these bikes second handed, guys smarter than me use heat and cold to seat them
Heat was used but probably not enough
I had this exact model with a 150cc head, bore, Arrow exhaust larger injector in carb and larger rear sprocket.
Out of all my bikes 125cc and up to 1000cc this was my absolute favorite bike.
It shocked people how such a small engine could be so fast.
I'm kicking my self for selling it all those years ago.
Two stroke is King.
I'm so jealous of you. Lol
Really nice rebuild mate.
Also remember having to cut something in a little black box behind the seat.
Some sort of restrictor.
I owned a 125 two Stroke from 16 to 18 and knew how powerful they are. But the power above 8000 rpm hit me completely unexpected. Awesome bikes
One of my childhood dream bikes. Will kill to find one now.
Get one! So much fun to ride it. Hopefully a fun riding video will be up soon.
I have never heard of an RS 125 tuono version until now, I only thought they made the fully faired bike, great video, love the acsent and you just earned a subscriber
Thank you for your nice words
Another small detail, you might want to check the squish gap. It should be around 1.5 mm stock. Every time you rebuild an engine that might change because of the new gaskets. There's usually three sets of gaskets, 0.3, 0.5 and 0.8 mm. YOu should select the one that gives you the closest squish gap to 1.5 (unless you want a higher compression ratio, but that's at your own risk, it you're not experienced). If your squish gap is 1.8 you'll lose compression ratio, a bit of power and you might have a slightly higher fuel consumption. In any case, a higher squish gap is safer than a lower one, even though these engines in 'racing mode' go as low as 0.7mm. However, for road use and reliability I wouldn't go below 1.2/1.3 as you might incur in the risk of knock.
I watched your series on the RS - great 2-stroke content. Keep it up!!!
Thank you
Bring a bike back from the dead - great video, and the Christmas gift was good, too!
Hehe thanks
Really nice video to sit and watch. Amazing transformation 👍👍
Thank you
Nice video man ,congratulations! Hope u still have it
Ottimo lavoro!
I have an Aprilia Rs 125 Chesterfield :)
Fantastically clean job 🔥
And a lightwight lives again ..well done
Great work! You are a very good mechanic.
Thank you
Good job?!!
2 stroke power 😉
Thank you for your video because i can see your configuration of the phbh 28 vs
138 gp 60 gp start and 70 gp starter.
266 on the middle i thing.
On me dtr 125 ktm lc2 it's really different...
165 gp 52 gp start and 65 starter..
And 264.
Bye
Thank you 😊
Nice restoration! Greatings from Italy!
deltajet17 thank you
Amazing project!
I'm about to do the same with a 2006 rs 125 that i bought for 800 euros 💪🏻👊🏻
Have fun and hopefully it's not too bad
This was a great build. I am just starting in on mine now (old Mexican Carabela) - inspired by this and a few other channels - thanks :-)
Thank you. Have fun with your build 😊
Congratulations, great work and beautiful bike :) I have the same Tuono 125. The bike should have also white crash pads mounted on each side. The silver colored weights on the handlebar are not original - they should be black.
Thank you for the comment. Were the crash pads original?
@@bikedogtor1663 hi, yes I suppose they were originally mounted. All the bikes in the official reviews have them. Yoi already have the holes on the body to mount them.
Excellent job, well done. Mine still has a long way to go but it is getting there.
I had an RSV 1000 Mille and the price on the parts was just insane. I did change the whole starter clutch on it and there was a one way bearing from a BMW that did fit if you modded it to turn the opposite way, it did cost like 1/3 or 1/4 of the price compared to the OEM part.
That's why I didn't buy anything from aprilia. After market parts mostly have the same quality and cost 1/3. I rode a rsv 1000 once and gave it back. It is so damnnn powerful 😄 too much for me!
lovely wee bike,have one aswell and its full power,although needs work,great project ,ill probs be back on here for any help!!
I try to help if questions come up :-)
Deutscher Akzent on point, aber richtig gutes und interessantes Video. 😉
Like hast du.
Danke :D
@@bikedogtor1663 Bidde. Ist die eigendlich offen oder gedrosselt?
una Moto de esas vale la pena restaurarla gran trabajo amigo y lo mejor tener todas las herramientas a la mano
Honestly, nice work. Really good job. I don't have the skills or tools, but assuming you have them, rebuilding 2 stroke machines - I won't say easy, that is too cheap a way of saying it, but more like, its within reach to take a lot of interesting machines and rebuild them. And have a lot of fun in doing it!
Thanks for the video!
Thank you! To own the tools is 20% of the job. To be honest to get the knowledge took many years and rebuilding many many things twice or three times. Just start somewhere :-)
Bloody hell I've never seen a rave valve stick that bad lol
😄 only the hammer could do the job
Is the aprilia rs 125 tuono 2004 a good first bike?
BTW love the vids keep up the good work
Yes it is but if you do not like to do mechanic work it's better to get a four stroke imo. If you want to learn how to ride and do the mechanics it's perfect.
@@bikedogtor1663 yes thanks man i was in kinda desperete needs bc i got my cofirmation gifts and it was aboute 2k so i am planing to buy a aprilia for that money but thank you
And i would love to learn to the mechanics by my self and maybe be as good as you one day
That's how I started. Expect to do most of the work twice until you really know it 😉
@@bikedogtor1663 yes or maybe get my dad or sum to duble check it haha just so its safe to ride
Good job. Like your format 👍🏻
Great bro..
By the way.. where do you live?
Thank you, I live in Germany
War und ist eine der besten 125er die es gibt. Bin sie auch gefahren und würde sie jedem weiterempfehlen der mich dannach fragt! Auch für die Renne n Top Einsteigerbike wenn auch ohne Motorbremse aber bei deim kleinen Bike brauchst du eh jeden Schwung den du haben kannst! xD ;P Kein Vergleich zu den viertakt 125ern von heute.
Great series! Pls keep doing great videos like this.
Thank you :-)
Nice restoration. I'm going to have this bike next month.. I'm swap my Honda nsr 150 for this bike.. 😁
Good decision have fun
Richtig geile videos danke dir❤👍 hab mir ne alte sx 125 zugelegt und will jetzt im Winter den motor restaurieren (hab glaub nen fresser) aber hatte bis jetzt immer schiss was falsch zu machen aber nachdem ich deine videos gesehen habe denke ich dass ich das schaffen werde🤝
So habe ich auch alles gelernt und ich mache nach 15 Jahren immer noch Fehler, das gehört dazu. Meine Videos sind auch nur eine Hilfestellung und keine professionelle Anleitung, vieles kann man sicher besser machen. Viel Spaß beim schrauben
nice job
What tires did you use for the bike? They look nice and soft, I bet they've got bags of grip. Nice video and well done on the resto.
Thank you for your comment. The tires are BRIDGESTONE BT016F PRO.
Mines been in storage since i was 18 (2008) I'd love to be able to rebuild the engine myself but im no mecahnic and i dont have these tools....
Im 5ft3 and love the look of this bike and 2stroke😀. Only problem is will i fit on it as in a shortie! ?
The bike is quite low but you have to sit on it to be sure :-)
Great work!
How did you clean your forks up? Or did you have them replated? Awesome bike man!
After cleaning they came out perfect, was lucky here
I would love to buy an Aprilia rs125 but it is not launched in my country yet
Cool montage. I enjoyed it.
Thank you
What are your thoughts on the quality of this bike? Does it needs a lot of maintenance for it to keep working properly? Like, does it wear down fast, and is it unreliable?
It is a fast and fun bike but it definitely needs some love. These two strokes with much hp wear quite fast, I think aprilia recommends piston change every 5.000 Kilometer for example. If you just want to ride and don't work on it get a slow and boring four stroke. If you want to learn and have fun get a aprilia.
Awesome video and bike!
NUTRIM thank you! These comments keep me doing the videos :-)
Moin ich will mir so eine rs kaufen. Da wäre meine Frage erstmal, ob ich die auch mit 16. Jahren fahren darf (natürlich mit der 15ps Drossel)?
Ja gedrosselt darfst du die fahren.
@@bikedogtor1663 danke 🙃
Great project! How much time did it take?
Thank you. It took about 5 months but I worked only around 4 hours a week on the Aprilia.
Just one question, that looks like the original exhaust but 'open' (without catalytic converter). Has it been opened and welded back, does it have a DMG or is it an aftermarket identical to the original (I think Mivv used to make one like the original for full power). Last question, does the Tuono have a phbh 28 like the RS or a 26 like the Aprilia Classic. What's your final gear ratio, 17/40? I believe the gearbox is the same as the RS; not the one mounted on the supermoto or classic. Anyway, if you have questions please ask, as I've rebuilt this engine and also tuned some for the racetrack and I find very few people to talk about it nowadays, particularly in ENglish.
I was wondering about the exhaust myself and think ist original but welded.
Great video
Hello where did you learn your skills? I have a RS125R 1994 and a 1993 project to do also but have not had the time to start yet! Rotex 123
I am an industrial mechanic but all motorbike skills come from try and error and many youtube videos ;)
Nice
Thank you
what about ignition timing? Or you just put back the magnet and that it?
No adjustment needed in this case
Sensationell! Sieht wieder genial au
Das finde ich auch
Mega top 👌

Is it a bad bike to own?
No its a fun bike 👌
It’s a beauty my friend . I’m 31 years old and I still have the rs125 from 2003 . Top speed 185 km/h ! Now I want to restore it .. I didn’t touch her for 3 years.
@@ralelrogue5800 damn man.
How do you get this bike so cheap? I see they cost at least 1500k in germany for rebuild condition
It was a friend of mine and I paid a little extra later from sold parts
What is your main jet with that Dellorto 28mm carburetor
Don't know anymore
Hi
Are the 2-stroke engines the same on all Rs models?
Thanks
No different years have different engines
@@bikedogtor1663 thanks 👍
jetzt will ich meine aprilia auch neu aufbauen haha.
ach und meine hat eine problem ins den leerlauf (drehzahl) zu kommen. bleibt ein bisschen bei 3k hängen und geht dann entweder nachdem ich die kupplung etwas los lasse runter, oder nach ner gewissen weile. wüsstest du evtl wo das problem liegt?
Nur zu :-) das klingt als ob die AS zu langsam öffnet bei der Drehzahl. Macht meine aber auch manchmal.
Oder die zieht von irgendwo Luft also irgendein Schlauch hat einen Riss oder so. War bei mir auf jeden fall
How did you drive a 125 when were 15 years old?
Bought when 15 driven age 16 😉
Funny Video 😍👍👍
i have plans to get a rs125 what would i think on
Yeah get one, awesome bike
@@bikedogtor1663 is there any standard problems w them??
Having lots of money use to have one was a aprilia rs125 extrema use to be a track bike but was put on road fast bike but gotta keep maintaining them all time
Where do you get one for that price?
A friend forgot about it for 10 years then wanted to get rid of it
hallo, kurze frage, wo hast du das motoren lagerset her? thx, andy
Die Lager habe ich einzeln raus gesucht und bestellt
@@bikedogtor1663 danke!
👍✌
I have the same bike but what do i do to unrestrict it mine only goes 110-120 kmph
Sounds like a rev limiter or you try an open exhaust
@@bikedogtor1663 so should i buy a arrow pipe? I have just unrestricted my cdi and its much more smooth but still only 110 kmph
Do you feel a real power growth above 8000 rpm? If not an arrow pipe is def a good invest
@@bikedogtor1663 i dont know what my rpm really is because my rpm needle is just bouncing allover the place wich i dont know why it does that either
@@patrickpedersen9505 Try a bigger carburetor and open pod filter
0:23 Forgot about Mito? :D
Cagiva Mito 125 was the fastest / strongest 125 but from what I heard also the fastest to the mechanic :D You had to service Mitos quite often
I own 50cc 2stroke Yamaha TZR and I LOVE IT :)
2 strokes OWN my friend! :D
Normally I drive zx636 2003 but the small 2 stroke sports bike turns WAY MORE heads :D The best for meets
I should replace it with 125cc though. 50cc is a bit too slow - cca 100 km/h.
I was surprised by the explosive power of the rs although I owned a 2 stroke before. It's so much fun.
i got my hands in a aprilla rs 50

Great taste in bikes 😉
It would have been better to install a pneumatic exhaust valve instead of the electronics that often has problems
Is the pneumatic version more reliable?
Price brake down?
Not done yet
I can tell you.
Cylinder honing 150-200; depending on the piston you take
crankshaft; if its damaged, youre going to pay 90 + 50-100 for reinforced rods (prox rods)
All bearings, o-rings and seals cost 120. they come in a neat set with skf bearings
fluids and stuff might add up to 50 bucks
all in all, it might cost 500-700 Euros for a complete rebuild with aftermarket, reinforced and or hardened parts that are proven in racing (like prox, wossner or vertex)
so a rebuild garantees a overall better integrity
they foookin fly, jet it stick a pipe on it and itl do 100 mph
Do not use the oil pump,it doesn’t work properly it took me 2 pistons to find it out,premix
I tust the oil pump when it is adjusted correctly. Maybe yours didn't work?
Bikedogtor am on a aprilla group on Facebook,most of them don’t use it because they shut off at certain rpm
@@mr420uk7 I have a 1994 Rs125R and a 1993 Rs125 never had any problems with oil pumps!

Mach deine Videos doch einfach auf deutsch. Dein deutscher Akzent ist unüberhörbar 🙄
Ich wollte in den 90ern auch immer eine RS. Hatte damals eine Yamaha DT80 MX. 9000 Mille kostet die Aprilia damals.
Es geht mir eher darum mehr Menschen zu erreichen. Eine Fremdsprache mit Akzent zu sprechen sollte im übrigen niemanden davon abhalten diese Sprache zu üben. Ich mache aber auch videos auf deutsch, zb meine aktuelle Serie.
Immer diese deutschen die probieren englisch zu reden schrecklich.

Rs125 2t not the Strongest
So which one is?
None really if you want reliable it has to be a 4t my most reliable bike so far iv still got Yamaha ybr custom 150cc never let me down but my rs125 let me down all the time
@@defrkingadame3995 Well I´ve got myself a RS125 06 and I must say it is reliable, only if you maintain it and know how to properly ride a 2 stroke. I´ve ridden more than 30 thousand kilometers on it in 3 years and the only thing I had to replace was the cylinder after 27k km and ofc the spark plugs and liquids... yet the bike has past 50 thousands on dash still running smoothly, every bike can be reliable if you know how to ride it properly
@@defrkingadame3995 it was built to be fast not to last
its easier to work on, doesnt brake due to electronic failure. these flimsy 4 stroke injection bikes; especially 125cc; break down quite often.
the rotax 122 engine is build to be rebuild. thats all. you wont even dare to open any other 4 stroke engine because u gonna feel like a mechanic; opening a car engine.
How can I contact u in private mate ?
