Using Evotech Performance’s innovative design, Evotech Front Fork Spindle Bobbins for the Yamaha Tracer 9 GT offer crash protection to the lower front forks. Within the injection-moulded nylon bobbin is a supportive, strong aluminium core which combine to make robust protection. Should an accident occur, the nylon bobbin is intended to receive any impact first. Also, the nylon is able to rotate to decrease stress and wear on the lower front end.
