KTT-4200 Dry conversion clutch kit STM EVO SBK from wet to dry Triumph Street Triple 765RS 2023-2025

STM EVO SBK 48D dry clutch kit with basket and plates for Triumph Street Triple 765RS 2023-2025

The STM EVO SBK wet-to-dry clutch conversion kit is a technical solution developed to transform the original clutch system into a dry clutch with slipper technology, directly inspired by racing applications. The kit includes a clutch basket, 48D clutch plate pack, and a new CNC-machined engine cover, creating a complete system for riders looking for greater mechanical precision, improved braking stability, and a more race-oriented setup.

At the heart of the system is the STM slipper clutch, designed to reduce rear-wheel hopping caused by negative engine torque during hard deceleration. This helps make the motorcycle more stable during aggressive downshifts and braking, reducing unwanted drivetrain reactions.

How does the STM slipper clutch work under braking?

The slipper system operates only during deceleration, when the engine generates negative torque. In this condition, the clutch modulates torque transfer to the rear wheel, helping reduce wheel hop, instability, and harsh reactions during downshifts.

Why choose an STM EVO SBK dry clutch conversion?

This conversion is designed for riders looking for a more race-focused solution featuring a dry clutch, slipper system, 48D components, and CNC-machined engine cover. Its main advantage is improved motorcycle control during braking and corner entry, especially in sport and track riding.
