Motorbikes change weight more than cars - an empty sedan versus one full of people and cargo might be say 25% heavier - but a naked bike and one with a heavy rider and riding gear plus full tank of fuel might double in weight. So your factory motorcycle dampers need more sophistication. If you have damping adjusters read our suspension setup tips to get the most out of them - but even if you don't have clickers read the section on sag because your OEM rear shock absorber will still have spring preload adjustability.
The most common solution is a pair of large locking nuts that screw on the threaded damper body. If you have pre-loaded the spring as much as you can and still have too much rider sag, consider a stiffer spring - read our suspension spring choice guide and browse Shock Springs & Hardware. For tight frames see our mechanical preload adjuster or for roadside ease use a hydraulic preload adjuster.
Consider matching with Suspension Tools for safe, accurate adjustments.
Browse our selection of upper preload rings, locking nuts and preload solutions to suit touring, track and everyday riding.
