SUSPENSION CHARACTERISTICS SOLUTION
Bike wallows through turns. Increase rebound damping.
Bike feels loose or vague after bumps.
Wheel tends to "pogo" or suffer continuous bouncing after passing a bump. This is
often noticable by watching the bike as it travels over bumps.

more pronounced over a series of bumps and is often referred to as "packing down."
Bike bottoms in dips or while cornering. Increase compression damping.
Bike has excessive brake dive.
Harsh ride, particularly over washboard surfaces. Reduce compression damping.
Bumps transfer through handlebars or seat.
Suspension seems not to respond to bumps. Tires chatter through corners or rider
is jolted over rough roads.
Changes in Load before the motorcycle is ridden any distance and after changing
the overall vehicle weight (adding saddlebags, etc.).
The front and rear preload setting will need to be adjusted for
the rider's weight and cargo. This adjustment should be made Changes in the load carried requires changes in the preload
settings. Carrying less weight than was used for setting up the

suspension requires decreasing the amount of preload.
Increasing the load carried requires adding more preload.

Enhanced Semi-active Suspension
Models equipped with enhanced semi-active suspension have
wires coming out of the top of both left and right fork
assemblies. See Figure 2-31. Adaptive Ride Height (ARH)
allows for a lower seat height when not moving without
sacrificing ride quality. If desired the system can also be locked Figure 2-32. ARH Selections

clockwise in the HIGH direction to increase preload setting,
or counterclockwise to decrease preload setting until
desired setting is reached.
