STM Slipper Clutch (Anti Hopping Clutch) - easy to fit, easy to adjust, easy to maintain. Technical excellence, quality and excellent value... can make your bike faster, easier and safer to ride.
WHY STM FOR STREET OR TRACK:
To help prevent rear wheel lock up and engine over running, to enable clutchless down shifting, to allow controlled sliding of rear wheel, to allow better take of and starts due to diaphram spring. STM becomes essential when improving Motor performance, as power increases you simply change the Drive Spring to cope.
IF YOU ALREADY HAVE A SLIPPER CLUTCH:
When you improve the Motor performance the Original Clutch and many other Slipper Clutches can become insufficient to handle the power, they may not be adjustable and the design could be simple to keep costs down. To avoid slipping It becomes important to use a higher specification STM slipper clutch on "non standard" engines where hp and torque has been increased. STM gives the ability to easily tune the clutch with a heavier primary springs with 10 kgs increases to get the right set up for the motor tune. The same secondary spring changes are available to get the right slipping for the rider and Track conditions. STM are very adjustable, most original Clutches are not.

SLIPPER CLUTCH TECHNICAL
• It applies pressure on the disc pack through the pressure plate;
• It replaces the many helicoidal springs.
• Allows adjustment when Motor performance is increasing.
• it applies pressure on the drum;
• it regulates the opening of the slipper clutch and regulates the engine braking to the wheel.
• It allows adjustment to rider preference - The lighter the spring, the less engine brake; the heavier, the more engine brake.
Primary Spring function:
• The primary and secondary springs are pre-loaded in order to generate an initial elastic strength of contrast.
• When you operate the clutch lever, the primary spring is compressed. The spring releases an elastic strength relative to the lever movement.
• STM 125mm diaphragm primary springs are offered in 10Kg increments and are changed as Horsepower increases. There are 13 different weights to choose from (sold individually).
• The 85mm diaphragm secondary springs are offered in 10Kg increments and are changed to rider preference and surface conditions. There are 6 different weights to choose from (sold individually).
HOW DOES SPRING LOAD CHANGE WITH COMPRESSION?
On closing the Throttle or changing down in gears, the engine's compression passes from the Cylinders to the gear box forcing the Clutch drum to rotate, with this action the secondary spring shifts the Clutch Hub outwards causing the clutch discs to disengage and moderate the compression shown at the rear wheel. The secondary spring is compressed in comparison with the initial drive and generates an elastic strength of contrast until power resumes. When power resumes to drive forward, the secondary spring to close the discs and start driving again.
ARE STM SUPPLIED WITH A SUITABLE SPRING SET UP?
All STM Diaphragm Slipper Clutches come with Primary & Secondary springs that have been calibrated for the specific application the clutch is intended for. The standard weight of both springs chosen by the STM Factory Technicians to be suitable for 90% of riders. One of the outstanding features of STM Slipper Clutches is that they offer a wide range of adjustment to suit any rider's needs. Both Primary & Secondary springs (weighted in Kilograms) are offered in 10kg increments and sold individually. Riders & engine builders can purchase additional springs to find the perfect combination to suit the rider preference and Horsepower output.
DIFFERENCE BETWEEN 90mm & 125mm PRIMARY SPRING.
The main difference is that with the 125 mm spring clutch, the elastic action of the spring is applied right on the disc pack. With the 90mm spring the pressure is not direct on the plates, because the spring is positioned in the centre of the clutch. The advantage of 125 mm spring is to give a softer clutch lever. The slipper clutch with a 125 mm spring is a later version of the 90 mm spring Slipper Clutch.
