On a 07 s4r will a billet clutch hub give more vibration than the stock Cush drive one. And is there any down falls to them.
I don't remember the brand off hand but I've not noticed any negative issues in the 2 yrs. I've been running a billet hub. It may be Pro Cutting I just don't remember but it was what ever brand Desmo times was selling.
Go for it man!
No extra vibs
Nope, no noticeable change vibration wise although I'm still using the stock flywheel.
I replaced the hub and basket with billet ones from VeeTwo a while back. That hub doesn't have the cush drive While the engine did spin up a bit faster on the throttle it didn't seem to vibrate any more.
