Ride Height Adjusters

Motorcycle Jack Up kits

Ride height adjuster kits replaces the stock (standard) links in multi-link and uni-track rear suspensions found on most Japanese sports and super bikes. Lust Racing ride height adjusters are made and developed for racing use. Replacing the links/tie-rods or "dog bones" provides the possibility to tune in the suspension and adjust the ride height without altering the shock absorber and spring settings. Indeed shock and spring settings can still be adjusted. Altering the ride height allows you to tune in your bike to fit racing track, track conditions and rider preferences. Adjusting the ride-height changes a motorcycles handling characteristics as the rake and the trail of the front fork changes due to the new angle or "stance" of the bike with a raised or lowered rear suspension. Rising kits will provide quicker steering response, and easier turn in. We do not recommend rising the rear suspension by more than 40...45 mm. Lowering kits increases high speed stability.

Rising kits / Jack up kits
We provide a wide range of motorcycle rear suspension rising kits. For most bike models we have several ride height options available. Jack up kits have become popular not only for racing applications but also in the streetfighter community. Rising the ride height can also provide taller riders with a more comfortable position. Please check that fitting ride height adjusters for traffic use is legal in your country.
