Bitubo Racing shocks makes a fully adjustable for spring preload, rebound, and high speed compression damping rear shock. The shocks for the TL’s weight less then 4 1/2 lbs! The Bitubo shocks replace the rotary damper and the “spring on a stick” for both the TL1000R. Your weight savings will be in excess of 9lbs! In addition to the tremendous weight savings you get a superior damping unit that will absorb bumps better, give you better traction, support the weights you will be carry better, and give you a more comfortable ride. We have different spring rates available for the shocks based on your weight, passenger weight, and how you are using the bike. While we try very hard to keep all popular shocks in stock sometimes we do need to order from Italy. For this reason please allow 2-3 weeks for delivery.
