I do not know about the AP one,but i've fitted the Brembo one and it's like a different bike when it comes to using the clutch.Pity you are not closer to me,'cos you would be more than welcome to give it a try.These are of course my opinions,i don't know what other people have tried.

I've had a Yoyodyne slave on my 916 for a few years and am very pleased with it. The reduced effort has saved a lot of wear and tear on my wrist. One thing I've noticed with larger bore aftermarket units is that they are very sensitive to proper bleeding as they tend to reduce the overall throw of the pushrod. If improperly bled it becomes difficult to find neutral due to clutch plate drag.

I can vouch for Nelly's at Cornerspeed good quality kit.
Much reduced clutch action and a lot smoother and piece of p*ss to fit.

on this one a while back in same section. the poor thing probably needs a Zimmerframe now:lol: try a search on my screen name if your intrested, I bought the stm version from tecmoto. excellent.

:rodent: you'd be faster on a zimmerframe.

I've got the evoluzione one and again. It's excellent quality and does help wit the lever pressure.

Guaranteed for 10 years against the dreaded and infamous leaks too (Are the others????).

Guido,
did you get the slave cylinder from a stockist in the uk or direct from evoluzione?

Nigel,

I got it direct from Evoluzione in the states. Came within about 4 days. Cracking service and the MD was real helpful when I had Q's about fitting it.

Try Nelly at Cornerspeed first. He does do some Evoluzione stuff and may have them.

I got mine before he was in business.

Guido

I do have one in stock. It's silver, and was used for er....... "research" purposes ;)
Never fitted/used £120 delivered ??
