The UFO Start Device for YAMAHA is designed to optimize starting performance in motocross (MX) and supermoto (SM) races. This sophisticated start mechanism ensures your fork stays compressed until you encounter the first bump, where it then releases automatically. The device comes pre-mounted on the supplied fork guards, making installation a breeze. The full package includes a pair of fork protectors for a complete setup. Whether you are a novice or professional rider, this start device will give you the competitive edge you're looking for.
