STM Dry Clutch Kit BMW S1000RR K67 (2019-2026) KTT-2700

Engineered to replace the factory wet clutch on the BMW S1000RR K67, the STM Dry Clutch Kit KTT-2700 is a precision-built assembly that draws on STM's racing heritage to deliver measurably better power transfer, sharper engine response and a significant reduction in rotating mass — exactly what demanding track riders and serious sport riders require from a drivetrain upgrade of this calibre.

Key Features

• Reduced power loss through elimination of the wet clutch's oil-drag losses, putting more of the S1000RR's output directly to the rear wheel
• Patented ball-ramp mechanism governs the anti-hopper function, providing precise back-torque limiting at high revs without the abruptness of a conventional slipper clutch
• Weight saving of approximately 0.7–0.8 kg by reducing rotating mass, with a tangible improvement in throttle response and rev-matching feel
• Prevents rear-wheel hop under aggressive downshifts, enabling controlled sliding with confidence rather than unwanted chatter
• Diaphragm spring design eliminates pressure-plate wobble, giving the clutch lever a smooth, progressive release with no dead spots
• Improved cornering stability during the clutch engagement phase, actively resisting front-end tuck caused by engine braking in mid-corner

Build Quality and Materials

STM has built its reputation on manufacturing clutch components to tolerance levels that satisfy WorldSBK and club-racing teams alike. The KTT-2700 kit reflects that pedigree: every component is machined from high-grade materials selected for their resistance to heat cycling and mechanical fatigue. The patented ball-ramp anti-hopping system is a proprietary STM design — not an aftermarket approximation — and the diaphragm spring is calibrated specifically for the S1000RR's engine character, ensuring consistent lever feel whether you are on a warm-up lap or pushing hard in the closing stages of a race.

Performance on Road and Track

Swapping the original wet clutch for the STM dry unit transforms how the S1000RR communicates through the lever. Engine over-rev on aggressive downshifts is curtailed cleanly, rear-wheel hop is eliminated and the reduced rotating inertia makes the motor spin more freely between gear changes. On track, where clutch heat build-up and fade can compromise lap times, the dry clutch's thermal characteristics offer a clear advantage. In sport road use the same qualities translate into a more engaging, connected ride.
