The tire feels as if it isn't staying in contact with the pavement when on the gas. The harsh, unforgiving ride makes the bike hard to control when riding through dips and rolling bumps at speed. The suspension's reluctance to maintain tire traction through these sections erodes rider confidence. Hitting bumps at speed causes the rear to bottom, which upsets the chassis. Ride is harsh, though not quite as bad as too much rebound - however, the faster you go the worse it gets.
Harshness hurts rear tire traction over bumps, especially during deceleration.
Medium to large bumps are felt directly through the chassis - when hit at speed, the rear end kicks up. The ride is plush at cruising speeds, but as the pace increases, the chassis begins to wallow and weave through bumpy corners. Poor traction over bumps under hard acceleration - rear tire starts to chatter due to lack of wheel control. Rear end wants to hop and skip when the throttle is chopped during aggressive corner entries.
