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: This adjustable link arm comes with a reversible insert. Testing determines the performance setting for competition use at a motocross track.
