I have been dragracing motorcycles for a lot years, and the consensus among the dragracers is that the stock Suzuki clutches are better that any aftermarket clutch. If you do go with Barnnet kevlar, which is probablly the best clutch for street use, you need to use their steels also, so that the stack height will be right. On my 98 Bandit, I used the complete clutch setup for a 1986 GSXR 1100, which is a better clutch setup than the Bandit clutch.
