When a rider uses SaddleGel, the forces created by road induced shock and engine vibration that are normally transferred through foam cushioning are absorbed and dampened by the SaddleGel, instead of being telegraphed to the body. This technology makes three significant comfort enhancing improvements: first, it dampens, or absorbs, engine and road vibrations, a common cause of rider fatigue; second it isolates the rider from all of the hard motorcycle pieces located below; and third, it conforms to the rider's butt and spreads pressure over a larger area to eliminate hot spots and loss of blood circulation. Eliminating the pounding and minimizing these forces result in lower fatigue, stress and exhaustion. The Medium Original Comfort Seat Pad has a soft-stretch cover that maximizes SaddleGel efficiency. The medium is perfect for the buddy seat of most sport bikes, dual sport bikes, and the smaller passenger pillions of cruiser and adventure bikes.; Viscoelastic molded gel improves blood circulation and shock absorption Easy on/easy off harness or quick throw over mounting options Quick-disconnect harness system mounts onto or over seat and remains in place when pad is removed (instructions included), or use the optional side-seat hooks Durable, fiber-reinforced black cover is unaffected by weather, water or perspiration Lifetime SaddleGel warranty
