BMW S1000RR Clutch Conversion Kit
A wise racer once said, “Power is nothing without control.” In stock wheelbase drag racing applications, these words have never rung more true.
The 2020 BMW S1000RR is certainly a powerful machine, and when Brock finishes prepping it for the Super Stock drag racing class, it will surely be a force to be reconned with… but alas, the bike has an issue from the factory that prevents smooth dead stop launches. The trend in the industry towards ‘assist’ clutches makes the OEMs happy because sufficient clamping force can be applied to the clutch pack without a harsh pull at the lever as a result of mechanical advantage, while also allowing a ‘slipper’ clutch action to help prevent wheel hop under aggressive downshifts. Unfortunately, this ‘assist’ design does not allow the rider to slip the clutch properly to obtain the quickest ET possible at the drag strip… so what now?
Brock teaches a masterclass in motorcycle clutch theory, maintenance, and tuning for performance while installing a Brock’s Performance Clutch Conversion Kit in his buddy T’s 2020 BMW S1000RR in his easy-to-follow style.
