Technology
Most tune by feel — some even by voodoo. We tune by data: calculated, measured, controlled for every motorcycle. The difference isn’t magic. It’s something you feel instantly.
Forces and oil flow are calculated, not guessed. Every valve design is based on defined flow targets and pressure profiles.
Damping behavior follows physical models. The base design determines quality — not the number of adjusters.
Force-velocity curves, not subjective assessments, define behavior. Every change is validated on the test rig.
Reproducible measurement data instead of gut feeling. That is how suspension is built that you can rely on.
Every motorcycle has its own mass distribution, geometry, and use characteristics. Good suspension accounts for all of that.
That is why every DR | BRAUN suspension is specifically tuned for its model — not sold generically.
Suspension Technology
Compression and rebound are designed for defined force targets. High-speed and low-speed ranges are separated and tuned independently.
Force ranges from 500 N to 6000 N at velocities of 1 m/s to 3 m/s are calculated and validated on the dyno.
Shim stack configurations, spool concepts, and valve sizing define damping behavior. The premium line uses licensed SPV valve technology.
Every valve design is based on defined flow targets and pressure profiles — not trial and error.
Every suspension is tuned specifically for its motorcycle model. Parameters are changed in a controlled manner and evaluated through measurement.
Cavitation, delays, nonlinearities, and inefficiencies are identified and systematically eliminated.
Before a product receives the DR | BRAUN seal, it undergoes defined motion and load profiles on the test rig.
Dyno measurements deliver reproducible force-velocity data. The name obligates.
Capabilities
Flow calculation inside dampers, valve sizing for defined force targets, pressure and flow behavior under dynamic conditions.
Shim stack configurations, spool concepts, and seal technology. The foundation of every damping characteristic.
Numerous test rigs designed, built, and commissioned in-house. Experience with systems from Roehrig, MTS, CTW, and Laba7.
Force-velocity measurements, defined motion profiles, closed-loop control. Reproducible validation.
Custom tools for force-velocity visualization, hysteresis analysis, and automated evaluation.
Every tuning decision is backed by data. No guessing, no gut feeling.
Every motorcycle model has its own requirements. Mass distribution, geometry, spring rate, and usage profile determine the design.
Setup data for every supported model. Documented, traceable, reproducible.
SPV Technology
SPV (Speed-sensitive Piston Valve) is a valve technology developed in Germany by Mototech Suspension. It automatically adjusts damping based on the speed of piston movement.
During slow movements (cornering, braking) damping stays firm. During fast impacts (potholes, sharp edges) the valve opens and lets the wheel work.
Conventional shim stack dampers are always a compromise: soft enough for comfort or firm enough for control. SPV resolves this conflict.
The result: better ground contact, more stability, and less rider fatigue — without manual adjustment.
DR | BRAUN licenses SPV technology for its premium line. Our personal relationship with the developer ensures technical depth and direct collaboration.
The SPV line complements the core brand. A customer who does not need SPV still gets a very good suspension.
Demanding riders, touring, adventure, ambitious street riders. Anyone who wants the most out of their motorcycle — without constantly turning adjusters.
Premium quality, honestly priced.
