The difference is about three hundred dollars for the two, but what? if any are the performance differences?
You already starting to prep the yammy??? :cheers:
I've heard nothing negative about either. At this point it could be all about the name and $$$.
The STM uses a single "spider" type spring that I've heard wears out somewhat quickly while the Yoyodyne uses conventional coil springs in their slipper.
I have a Yoyodyne in my RC51 and have been very happy with it.
BTW: The Yoyodyne slipper is made by Sigma.

I've used both (I have an STM in my 748 & a Yoyo in my CBR).
The only real advantage the STM has over the Yoyo is that it is more easily adjustable for the amount & point of slip, but that requires you buy additional spider springs.
Me, I'd go with the Yoyo, save the $300.00 and put it towards a school or tires.
I have an STM that I'm very happy with, I liked the fact that I could get a 35 degree ramp (less engine braking). Having said that, lots of people swear by the Yoyos and they seem to be a better value.
Go with the yoyo. They work great and you`ll find the customer service outstanding! :thumb:
Thanks for the input. I think I'll go with the Yoyodyne. Thaks again.
yoyodyne would be my choice, Fred is great at helping and answering questions,
your RRS Instructor discount gets it to you fast
Thanks Rick!
I really like Fred and his company Yoyodyne is great. But I have used both and would definitely choose an STM over the yoyodyne slipper. The Yoyodyne has some great ideas with more parts to make the clutch easier to replace parts but those same parts can come loose or back out and the clutch can be less reliable for that reason. The STM is absolutely bulletproof and we have never had any problems, the yoyodynes we have used we have had to do what I would consider to be extensive maintenance.

Opps.. I forgot about that, I personally had 2 studs start backing out on me this season, even with the industrial permanent strength Loctite I applied before the season (luckily I check my clutch it VERY often and caught them).
The studs on the new clutches are pinned in place.
They do not back out.
(Problem Solved)
Fred, good to know, mine is from back in 04.
Like I said, think I'll go with the Yoyo. seemed like good enough people when I spoke with them last week. Thanks again for everybodys input. Bye the way this is going into an 04 R1 for next year. Should be a lot of fun!
