The Tractive HPA for BMW S1000R (2014 onwards) is a hydraulic preload adjuster designed to let you change rear spring preload without tools. It uses a sealed, closed and pressurised hydraulic system to keep adjustment consistent and reduce the chance of aeration. This style of adjuster is typically fitted to make load changes simpler when switching between solo riding and carrying luggage or a pillion.

Who is this for?

Riders who regularly change bike load and want quicker preload changes.
Owners who prefer a remote-style preload adjuster rather than accessing the spring collar directly.

Design & features

Sealed, closed and pressurised hydraulic preload adjuster architecture for stable operation.
Hydraulic adjustment mechanism intended to make preload changes more convenient.

Tuning Controls

Hydraulic spring preload adjustment.

Before You Install

Confirm model fitment for BMW S1000R (2014 onwards).
Check available mounting space and hose routing (if applicable to your installation) before final assembly.
