As used by Buildbase BMW

Benefits: Easier control of the rear brake enabling you to control wheelies whilst cresting a rise in the track, or for those lightning quick race starts without fear of flipping the bike. More importantly it is excellent for positioning the bike mid-corner as you can control rear suspension compression, by dragging the rear brake, which causes the motorcycle to tighten its line allowing the power to be applied earlier, enabling a faster corner exit speed. The latest evolution provides the user with the ability to alter the lever position to obtain that custom feel.

"Using the footbrake is ok, but you can’t reach it in right-handers, so this Speedycom adjustable thumb brake, fitted to my 2015 BMW S1000RR race bike, is perfect. It’s nicely produced in black anodised aluminium and has survived a huge crash already. It works so well, especially in the wet, that I keep going for an imaginary thumb brake when I ride different bike" Michael Neeves - MCN

Full Race kit includes: Black anodised aluminium fork clamp – 54mm fork diameter (smaller fork diameters require shimming, which can be provided at no extra cost) Black anodised aluminium thumb brake lever (adjustable for ratio) Stainless steel fixings with anti-vibration washers Brembo 13mm bore master cylinder.
