DescriptionThe whole story▼
Converting the standard wet clutch on your BMW M1000RR K66 to a dry unit is one of the most rewarding upgrades you can make — not just for track days, but for every spirited road ride where feel and control matter most. The STM dry clutch kit KTT-2700 delivers measurable reductions in drivetrain power loss, a significant saving in rotating mass, and a clutch lever action that is genuinely more progressive and confidence-inspiring in daily sport use.
Key Features
- Replaces the stock wet clutch with a performance dry clutch, reducing power loss through the drivetrain
- Patented ball-ramp mechanism governs the slipper/anti-hopper function for precise control at high engine speeds
- Prevents rear-wheel hop under hard downshifts and allows controlled sliding without unpredictable tank-slappers
- Weight saving of approximately 0.7–0.8 kg by reducing rotating mass — felt immediately in throttle response and direction changes
- Diaphragm spring eliminates pressure-plate judder for a smooth, linear clutch-release feel every time
- Improved corner-entry stability: the closing phase of the clutch is better managed, reducing front-end dive under engine braking
Everyday Usability
Unlike some dry clutch conversions aimed purely at circuit use, the STM KTT-2700 has been engineered to work just as well on a morning canyon run or a Sunday sport ride as it does in a pit-lane setting. The ball-ramp anti-hopper calibration keeps downshifts smooth and predictable in traffic as much as under braking for a hairpin, and the diaphragm spring ensures the lever pull remains consistent whether the clutch is cold or fully up to temperature. Riders who clock regular road miles on their M1000RR will notice the improvement in corner confidence most of all.
Engineering & Build Quality
STM has built its reputation on precision-machined clutch components used across World Superbike and other top-level competition, and the KTT-2700 carries the same manufacturing standards into a bolt-on kit format. The patented ball-ramp geometry is the centrepiece of the design: by controlling exactly how the slipper function engages and disengages, it eliminates the abrupt rear-wheel lockup that a standard or poorly calibrated slipper clutch can produce. The diaphragm spring acts on the pressure plate to prevent wobble during engagement, giving the lever a feedback quality that feels more like a race-prepared machine than a production motorcycle.
