Nice shocks. But they are what they say - heavy duty. I have them on the lightest setting for my daily solo combat commute. They're just perfect for two-up weekend flings.

Important Product Notes

Note: When shocks are shorter than stock, clearance must be carefully checked for potentially dangerous interference.

Note: Standard Duty shocks are for ride loads under 225 lbs., Heavy Duty shocks are for ride loads regularly over 225 lbs.
