Product information "Wilber shock absorber – Bobber – Type 643 Competition"
Wilber’s high-end shock absorber with compression and rebound adjustment for Triumph Bobber
The Triumph Bobber models are significantly too stiff as standard and have a shock absorber with very poor responsiveness.
This, combined with the very short suspension travel inherent to the design, results in an uncomfortable ride.
That’s why anyone who rides their Bobber a lot and values comfort should fit a decent shock absorber.
If you’re looking for an absolute top-of-the-range shock absorber that can be fine-tuned even further, the Wilbers Competition shock absorber is exactly what you need.
The shock absorber is individually tuned to your weight and delivered perfectly fitted.
The shock absorbers comewith ABE approvalfor your motorbike (so they do not need to be registered separately with the TÜV).
PLEASE NOTE: no ABE yet for Euro 5+ models:
The shock absorber also fits the current Euro 5+ models – but these are not yet included in the ABE. An ABE update is expected next season, when the model will also be listed.

TheWilbers Type 643 Competition QS shock absorbersare high-quality, top-of-the-range units offering a full range of adjustment and customisation options:
- Compression damping adjustment (high and low speed)
- Rebound damping adjustment
- Expansion tank
The spring preload (which is, of course, pre-set to the correct level) is infinitely adjustable.
The rebound and compression damping can be adjusted in 22 clicks using the rotary dial.
Radial pistons, wet guides and Teflon-guided swing bearings ensure a smooth response.
Mechanical spring preload (Wilbers X-PA)
TheX-PAallows you to adjust the spring preload – and thus the vehicle ride height – in no time at all using the supplied socket spanner. The purely mechanical adjustment mechanism is extremely lightweight and, thanks to its robustness, is ideally suited to withstanding heavy loads. The adjustment range is 15 mm.

- Rider’s weight – (including motorcycling gear)
- Luggage weight
We recommend only taking this into account if you ride with a passenger very regularly. Otherwise, we advise tuning the shock absorber perfectly for solo riding, as a shock absorber can only be optimally adjusted for one weight. - Percentage of riding done with a passenger and luggage
- Rear shock absorber setting: Comfort / Standard (our recommendation) / Sport
- Intended use: Race track / Road / Off-road
Classicbike-Raisch Tip / Accessories
- If you want an all-round good suspension set-up on your bobber, we recommend having a cartridge fitted to the fork (see accessories below the product description)
- Many bobber riders complain that the footpegs touch down too early. To address this, we offer a suspension lift kit for the shock absorber or a complete multi-part kit. Both, of course, also work in combination with the Wilbers shock absorber. See the accessories listed below the description.
