Find other: HMF Clutch Kits
The HMF clutch weight system is designed to address the lack of drivability of today's high performance ATV / UTVs. Rarely can you look at a product and immediately understand how it works. This is one of those products. The weights roller track is designed with shifting in mind. The roller track is flatter on the top than the bottom. So when the secondary clutch senses the need to back shift and provides a slight pull on the belt, the weights responds by quickly removing as much as 7 grams of weight from the tip and allows the weight to quickly roll back during back shifting. This is the first and only flyweight with a built-in back shifting function. It's the only weight that communicates with the secondary clutch. Now you have a truly smart CVT system, not just two clutches pulling the belt in opposite directions.
Today's engines produce high torque at low RPMs requiring heavy clutch weights for the CVT system to operate properly. The system was specifically designed for high performance use. Because of its unique roller track design, it immediately senses the need to upshift or back shift, and can move as much as 7 grams from one end of the weight to the other making this the ultimate high performance weight flyweight. How does it perform on the trail? For the high performance trail riders; during testing, all test riders reported that this weight never stops pulling. Excellent off-the-corner performance is achieved by moving weight in the form of a ball bearing from the base of the weight to the tip as the clutch shifts out. The highly refined roller track and ball can move as much as 7 grams from the base to the tip. The roller track is designed so the ball is always in motion - no flat spots. The weight knows instantaneously when to aggressively start your shifting!
