FHN-S170 STM Wet Slipper clutch Honda CBR1000RR-R 2020-2026

The STM slipper clutch for Honda CBR1000RR-R 2020-2026 is designed to improve motorcycle behavior during hard deceleration, when engine braking generates negative torque through the drivetrain and can cause rear-wheel hopping. This phenomenon can reduce traction, stability, and corner-entry precision, especially during sport riding and track use.

The STM system operates specifically during braking and deceleration, modulating negative torque transfer and helping keep the motorcycle more composed during aggressive downshifts. Construction uses premium materials such as Ergal aluminum alloy, selected to reduce weight compared with an OEM clutch while maintaining high mechanical precision.

Accurate machining and a racing-oriented design philosophy make the STM slipper clutch a technical upgrade for riders looking for better rear-wheel control, improved braking stability, and more precise drivetrain response.

STM slipper clutch for Honda CBR1000RR-R 2020-2026

The clutch is developed to complement the performance characteristics of Honda's superbike, improving control during braking, downshifting, and corner entry without interfering with normal operation under acceleration.

How does the STM slipper clutch work?

The system activates when the engine produces negative torque during deceleration. In this phase, the clutch modulates engine-braking torque transferred to the rear wheel, helping reduce wheel hop and loss of grip.

What are the benefits of the STM clutch on the CBR1000RR-R?

Reducing drivetrain reactions under braking provides greater stability, improved traction, and more precise corner entry. The use of Ergal also helps reduce weight and create a more performance-focused configuration.
