STM APRILIA HONDA KAWASAKI MV AGUSTA SUZUKI TRIUMPH YAMAHA

STM originally engineered their slipper clutches for the Official Ducati World SBK team, and this revolutionary technology soon led to 2 world championships for Ducati. Originally designed for Ducati's dry clutches, STM Slipper clutches are now available Honda Kawasaki Triumph Suzuki and Yamaha wet clutches as well. Now you can take advantage of STM's rich racing heritage & experience and apply Superbike technology to your bike!

STM Slipper Clutches - Ride faster and with more control with the installation of a STM Slipper Clutch! Serious riders will likely have experienced the rear wheel chatter caused by engine braking during aggressive down shifts. This chatter unsettles the chassis and forces the rider to slow down to bring the bike under control - while losing valuable time and speed. Slipper Clutches lets riders bang through downshifts and smoothly delivers power into and out of corners while maintaining traction.

Features:

Wet slipper clutches uses a forced lubrication system
Features a 125mm / 121mm / 90mm diaphragm spring depending on model
Diaphram spring design provides more pressure lock up and less drag than helicoil springs
Digressive lever engagement
Uses OEM basket and clutch plates
A must-have for racers and a huge performance upgrade for street riders!

Fine Tune your slipper clutch set-up by installing different springs! Changing the primary spring accommodates more horsepower and changing the secondary spring amplifies / reduces the amount of engine braking!

Progressive Engagement Plate (PEP) - Clutch plates with PEP have quicker clutch engagement. This allows for easier race & drag launches with less chance of "bogging down" at incorrect RPMs. With PEP clutch feels "lighter" the more you depress the lever, rather than the more linear non-PEP clutch plates. PEP is a rider preference and one is not necessarily better than the other.
