so i've recently just bought myself an rs125 tuono, and i am looking at buying a performance exhaust for it.... i'm stuck between the gianelli exhaust with a stepped woodruff key to advance the ignition timing, or a road or race arrow exhaust.



any suggestions??

What kind of a bike do you want?

The arrow will also include an advanced woodruff key, as long as you buy it new.

from what I know, they are both the same exhaust. Made in the same factory in france and the only difference is the end cans.

I doubt that, but alot is possible nowadays..

I would go for the Arrow, even though I've only had Giannelli myself..

Assuming price difference is the same where you live, as where I live.

I have been a huge Jolly Moto fan from back in the days of tuning RS50's to the limit, they seem to make an incredible pipe for all out performance at the expense of bottom and mid range...of course with the stock ignition timing this may be a non issue. I will be trying the ignition key in the coming week or two, and honestly I expect a decent gain, especially with my new 34mm Keihin carb I picked up last weekend...I love Keihins, they tune so freaking perfectly!

Alright there, I would be guessing that you want to have a hell of a time jetting and setting up!! The RS does not have any info to start you off and you haven't done anything lke this before. You will find it a lot easier to tune the standard 34mm carb. Plus the bie and carb match up better.

gman, i wasnt sure if that was to me or micah so i thought i'd answer anyway if it was to me :D

jetting and setting up isn't a problem for me, my dad is a bike mechanic and has road and race tuned rs 125s :D (not that i want it race tuned as a new bike lol) He gave me all my basic knowledge on engines and taught me how to rebuild small cc engines (ie 50-125) at 12 years old. My dad has helped me with any project or peice of tuning i have taken on and he allowed me to help him rebuild his yamaha lc350 engine.

my dad said about the jolly moto can being a wicked pipe, but very expensive. He also has an account with the people who sell arrow pipes, and an account with gianelli uk, so getting the pipe isn't hard either lol. He also has stacks of data on pretty much any bike including the rs's as he is an aprilia specialist :D

Tuning the engine to suit the pipe is not an issue for me either. The Jolly Moto comes VERY well suited to the stock port durations and area, add the right carburetor, I have both the 34mm Kehin PWK and the 34mm Dell"Orto, advance the timing by 4 or more degrees (still working out these numbers) and you will have a very serious and pretty much reliable race or performance street engine.

I personally do not like offset keyways or woodriff keys, they are much weaker than the normal non offset variety and I have personally seen plenty of them fail. I am probably going to try it as a simple test item but then slot the timing backing plate for actual adjustment or buy on the Honda electronic "in line" timing modifiers.

I am pretty excited about the new Keihin carb I got, well used actually, but free was the right price. The PWK carbs are absolutely brilliantly easy to tune and are designed for awesome performance and jetting resolution FOR two stroke engines. The Dell'Orto 34mm I have been playing with is so far the best Dell'Orto carb I have ever used so I cannot really offer any complaint about it at all.

I have an Arrow on order to see what it looks like in terms of measurements and fit and finish. I expect it to be about the same as their other Street 2T pipes, a marginal improvement over dead stock but in the case of these late model USA 125cc Aprilia's the stock pipe is actually very well designed.

Look for a pipe test in the future, it is coming once I get more than three or 4 options on hand for testing. I really want to get my mits on a Jolly Pipe and try modifying a Honda RS125 pipe to fit as well.

micah, from what i've heard you do a very good job when it comes to tuning 2t's :D

i look forward to hearing the results :D

Evotech performance makes this tidy little piece.

A bit more racy than the stock part, and noticeably lighter as well:

what kind of sound are you looking for?
arrow are quite loud and raspy, giannelli sound like stock (if you get the new gp version one. i have this pipe btw)
i shortened the endcan and now it sounds awesome imo:)

$51 form thing any metal worker could make it 30 seconds with a 1" and half of alu and bend and cut it into place.

i couldnt make that in 30 seconds, and i know how much work went into that. cnc cut, looks like cnc or press brake bends, and powder coated? looks good for $51

I'll show you mine tomorrow if can get a picture. That will snap the first time you hit the tarmac.

to put it into perspective, a uk made harris item ,which i presume is of similar quality, although not powder coated is 37.45 plus postage, which is roughly $56us. so the u.s. item is a bargain, yes?
