Linkage. Ride Engineering's newest product is a suspension link to lower the back of the motorcycle to help balance out the bike. This improves handling and keeps the bike going straight in whoops allowing the rider to be much more aggressive. It also keeps the back end planted in braking bumps. Stiffens the initial part of the stroke for better control and less wallowing in rough sections of the track. Typically, the bike feels more balanced and predictable while handling is improved in flat and off-camber turns, driving the bike forward instead of sliding sideways. Comes complete with all necessary bearings and seals. Detailed Specifications: Now available for the new 2019+ KX450 chassis, Ride Eng.'s new performance link is a key ingredient to balancing out the suspension, using all the travel, and improving handling.
