BMW right-side shaft drive manual

We recommend that the kit be installed by a specialised workshop.

Required tools:

1. Torque wrench and socket for tightening the motorcycle axle nut.
2. Small torque wrench and Allen key for tightening the clamp screws.
3. Medium-strength threadlocker, Loctite 243 type.

The resonator is mounted on the right side of the swingarm, except on motorcycles with a single-sided swingarm.

Next, attach the clamp with the resonator inside to the support, following the instructions below.

Keep the body of the resonator positioned in the clamp as shown in the drawing. Tightening torques: central bolt 2.3 Nm, upper and lower bolts 1.8 Nm. Note: the spacer (included) is only needed on the GS model with wheel fender or mud flaps.

1. Upper screw: 1.8 Nm
2. Central screw: 2.3 Nm
3. Lower screw: 1.8 Nm
4. 9.5 Nm with Loctite 243 or equivalent medium-strength threadlocker
5. 24 Nm with Loctite 243 or equivalent medium-strength threadlocker

Only for BMW with fender

1. Upper screw: 1.8 Nm
2. Central screw: 2.3 Nm
3. Lower screw: 1.8 Nm
4. 9.5 Nm with Loctite 243 or equivalent medium-strength threadlocker
5. Spacers
6. 24 Nm with Loctite 243 or equivalent medium-strength threadlocker

Calibration

Turn towards + for more sensitivity

Turning the adjustment towards + loosens the spring, allowing the Resonator mass to move more freely. It reacts sooner, cycles faster, and picks up smaller, more frequent vibrations from the road.

The result is a livelier, more sensitive feel: faster reaction, more movement, and more response to the surface beneath the tyre.

This setting is ideal for rougher, more textured surfaces: worn asphalt, cobblestones, secondary roads, and stretches where the tyre is constantly working.

Turn towards − for more control

Turning the adjustment towards − compresses the spring, making the Resonator more selective. It responds less to minor chatter and focuses on stronger, more defined impacts.

The result is a calmer, more controlled feel: fewer unnecessary reactions and a stronger focus on bigger changes in the road.

This setting suits cleaner roads with occasional bigger hits: potholes, surface changes, speed bumps, and sharper impacts.

In short:

+ Hz → means more sensitivity, faster reaction, and better response to frequent low-level vibrations.

− Hz → means more selectivity, calmer reaction, and better response to isolated stronger impacts.

When you check the torque of your motorcycle's main bolts, include these screws in your check.
