Thinking about fitting a Slipper Clutch to my 899, mostly for track use. Sigma performance have been recommended. Anyone have experience, good or bad, with slipper clutch fitted to 899. Thanks for any info.
No slipper as standard on 899, there is adjustable electronic braking, but rear still locks up. New 959 has one.
i have a STM on my 899,no problems at all,its just a shame to have such a thing of beauty hidden within the engine,it has a natty click when pulling in the clutch leaver,not sure if this is common with all slipper clutches.Sigma are excellent clutches and i am sure you will have no problems in fitting one.
I've had EVR and STM, on different bikes. STM all the way as you can adjust the amount of slip by fitting a different weight secondary spring. It made a huge difference to my S1K I found the EVR made no improvement over my 1199 Panigale standard slipper clutch. Both track only Davy
I have a ducabike fa899oil slipper clutch i am about to fit You need to make sure you have the clutch basket tool to remove the nut also if you fit a ducabike clutch you will need a different tool as this is a 6 pin clutch not a 5 as standard If you need any tools i have a friend who makes them his email address is vince_goosey@hotmail,com
I be got a sigma on mine and it's ace, simmytt is right about the feel it takes a while to get used to it
Personally think Sigma tend to be pretty good, what's the projected service life on a set of plates? Similar to a standard clutch? If not it may be worth considering the mag clutch cover because it's a 2 piece cover
Mag case would be good, don't know if it will be worth the additional cost. Quote from Sigma Performance FAQ's "Will the clutch plates wear more quickly? Our experience is that for normal track day use and up to national level racing the extra wear is negligible The plates can wear more, its just a question of use and how much work you ask the clutch to do. In normal circumstances the only work the plates are doing is holding the clutch centre up the ramps; that doesn't require that much power in the great scheme of things so the clutch doesn't get too hot and therefore there is little additional wear."
