Bitubo twin shocks bring modern damping to bikes with two rear shocks: classic Japanese and Italian bikes, Harley-Davidson and other cruisers, cafe racers and scooters. They come as a matched pair, built to the correct length for your model, with red, black or chrome springs to suit the look of the bike.
Which Bitubo twin shock?
| Family | Adjustments | What Bitubo says |
|---|---|---|
| WMB | Spring preload | Affordable bolt-on upgrade with fine preload adjustment |
| WME | Spring preload and rebound | Adds rebound adjustment for more comfort on long trips |
| WMT | Preload, rebound and compression, piggyback reservoir | Developed for cafe racers, modern classics and Harley-Davidsons |
| YGB / YRB | Spring preload | Made for scooters |
Length and spring colour
Harley-Davidson twin shocks are listed by eye-to-eye length in millimetres and inches, so you can keep the factory ride height or lower the bike. The spring colour is in the title: red, black (02 or 02V2) or chrome (03). Everything else about the shock is the same between colours.
Frequently asked questions
Do Bitubo twin shocks come as a pair?
Yes. Bitubo twin shocks are sold as a matched left and right pair at the price shown.
Can Bitubo twin shocks lower my Harley?
Harley-Davidson fitments are offered in several eye-to-eye lengths. Choosing a shorter length than stock lowers the rear, but it also reduces travel, so check ground clearance and sag with a workshop before going much lower.
What is the difference between WMB and WME?
WMB shocks adjust spring preload only. WME shocks add rebound damping adjustment, which Bitubo says improves comfort on long trips.
