STM Dry Clutch Conversion Kits for TM Racing Motorcycles

Upgrade your TM Racing motorcycle with an STM Dry Clutch Conversion Kit, combining competition-developed slipper clutch technology with a complete dry clutch conversion engineered for high-performance supermoto applications.

Our range of STM dry clutch conversions for TM motorcycles covers the TM 450 SMR, 450 SMX and 450 SMK, with applications across current and recent model years.

TM 450 Dry Clutch Conversion

TM’s 450 supermoto platform is built for serious performance, making clutch control particularly important during aggressive braking, rapid downshifts and hard corner entry.

STM’s TM conversion kit features a CLG slipper clutch, Z40 clutch basket and CNC-machined crankcase components, creating a complete performance-focused dry clutch system.

An STM TM 450 dry clutch conversion is ideal for riders looking for:

• Complete dry clutch conversion

• STM CLG slipper clutch technology

• Z40 clutch basket

• Precision CNC-machined components

• Improved clutch control during aggressive downshifts

• Reduced rear-wheel instability under engine braking

• Race-developed STM engineering

• Distinctive dry clutch sound and mechanical appearance

• Premium upgrade for supermoto, track and competition motorcycles

STM Dry Clutch for TM 450 SMR, SMX & SMK

The STM conversion range includes applications for the TM 450 SMR 2021–2025, TM 450 SMX from 2021 and TM 450 SMK 2022–2025, giving riders a properly engineered clutch upgrade for some of TM Racing’s most focused supermoto machines.

On a motorcycle designed around lightweight handling, strong braking and aggressive corner entry, an STM slipper clutch can become a genuine performance component rather than simply a visual modification.

Whether you're building a TM 450 SMR race bike, preparing an SMX for track use or developing a high-spec 450 SMK, STM provides a serious clutch conversion designed around competition use.
