EP Spindle Bobbins Kit for the Husqvarna Vitpilen 401 project from the sides of each wheel, offering protection to the wheel spindles, lower front forks, brake calipers and rear swingarm. The black bobbins are easily installed and held in place by a rolled-thread spindle rod. The durable materials of injection-moulded nylon and aluminium are designed to be first to receive impact should an incident occur, reducing costly damage to the motorcycle.
