No compromise between style and performance. The 641 Piggyback shock with external reservoir was specifically developed for the new Harley-Davidson Softail models. The included bracket positions the reservoir so that it integrates seamlessly into the overall look of your bike — functionally designed without disrupting the clean appearance.
ClubStyle stands for reduction, precision, and a clear statement. That is exactly what this shock represents: entirely handmade, precisely tuned to your rider weight and riding style — not a mass product, but true custom manufacturing.
The piggyback design ensures more consistent oil temperatures and therefore significantly improved damping reserves. In addition, compression and rebound damping as well as spring preload can be adjusted precisely to your needs, allowing you to fine-tune the suspension exactly as required. You will feel the difference from the very first meter: more direct response, better feedback, and increased control.
Before production begins, we configure the shock together with you. Your rider weight, passenger use, and preferred riding style — all of this is taken into account. The result is a suspension setup that fits you perfectly from the start, rather than being compromised after installation.
“Anyone who has ridden a custom-tuned shock once understands why there is no going back.”
Like all Wilbers products, the 641 Softail Piggyback comes with ABE (General Operating Permit) and is backed by a 7-year warranty — ensuring long-term enjoyment of your suspension.
