The bike loses the right hand instrument cluster. But all brakes and lighting work as per normal. It even hase reverse via the SW10 display.The bike does have the option of regenerative braking via a thimb throttle mounted on the;left part of the handble. We actually do not like this as it changes the ergonomicas of the brake lever (moves the lever to the right an inch). We will fit this is you want. However we do like a small amount of throttle off regen braking (like braking a 4 stroke MC).
