Why not have the same adjustment on your shock and your fork?
 
These fork caps allow you to precisely adjust the preload on your fork springs to match your riding conditions. Whether you run a large tank, with or without luggage, solo or 2-up, the adjustment is easy with a 12mm wrench.
 
Maybe you want a plusher ride on those washboard roads or heading out for a BDR trip with all your camping equipment. No matter your plan, it's useful to adjust the preload on your suspension for optimum handling.
 
These premium preload adjuster fork caps are built with a bearing-mounted spring pressure plate and have built-in pressure relief valves.
 
They fit nicely on the Kawasaki KLR650 Gen2 or Honda XR650L but double-check that you have the necessary clearance with your handlebar if you've modified your position. These fork caps will also fit an XR and a DR; check the fitment section for specifics.  You need 1.5" or 38mm clearance from the top of the fork tube.
