Important to know
Shocks slightly longer or shorter than the stock length can alter the head angle, affecting steering response. Before installing shocks that differ from the OEM length, ensure adequate wheel travel to prevent clearance issues (e.g., swingarm/axle to exhaust contact). Heavy-duty applications are recommended for motorcycles operating near maximum load capacity more than 50% of the time.
