Tamer’s rear Holeshot Hookup starting device is the perfect addition to the front Holeshot Hookup for the ultimate holeshot. Accompanied by the front device, the rear device together completely immobilizes the suspension making the bike rigid for the start ensuring that all transfer of power and energy is used to move the bike forward, so there is no energy loss of power in the suspension as in a bike without a rear starting device. This concept works excellent in all conditions from dry slick to tacky to concrete.HOW DOES THIS WORK:The Tamer Rear Holeshot Hookup works in 2 stages.STAGE 1 - When you are ready to start, you hold the front brake, apply the throttle and let out the clutch until it begins to engage or "chatter". Without a rear device, the rear of the bike raises up during this time and when you leave the gate, the rear has to settle back down and this absorbs energy from the motor that could be going towards forward motion. With the Tamer rear Holeshot Hookup, the rear of the bike is not allowed to raise up during take off ensuring that all energy produced by the engine is transferred to a forward motion. This equals 3 to 4 tenths of a second.STAGE 2 - Without the device, the rear of the bike has raised up, you dump the clutch to take off and the rear shock settles down and by doing this, you preload the rear shock and when the rear tire makes contact with the gate, the shock rebounds and the rear tire looses traction with the ground. With the Tamer Holeshot Hookup installed, the bike is already settled down and when the rear tire makes contact with the start gate, it releases the latching system and drives the rear tire into the ground without loosing any traction. This can equal 4 to 5 tenths of a second.All in all, this action translates into a full bike length advantage out of the gate over the others without a starting device.The Tamer Rear Holeshot Hookup is a bolt-on system and will attach to any stock and most aftermarket linkages available. The latch system attaches to your OEM shock bolt.
