High Thrust Clutch 301900, HiT301900, Kymco MXU 400

Invention: a little change that makes big difference.

A good clutch should transmit engine torque to wheel torque efficiently.
However, power loss always exists, for ALL clutches.

So we invented something new, a patented HiT system that can borrow engine torque directly,
and then add this extra power to the clutch shoes.
In this way, you get at least 35% higher force to grab the bell,
the clutch pads won't over slip, and the clutch bell won't be over heated.
We shorten the pad slipping time to exactly what your clutch needs. Never over do nor waste effort.

The patented HiT design is a true design, not just adding a screw to change springs for fun.
Therefore HiT clutch performs smoothly at the time of engagement, as well as disengagement.
Get your vehicle "HiT clutch inside."


"HiT Clutch uses a set of interlocked moveable plates to combine the engine torque and centrifugal force to achieve the highest possible power transmission as a CVT clutch. Unlike those conventional clutches on the market, this innovative design realizes a simple yet effective concept, which generates more power from the engine to work on clutch weights and then the clutch bell, and to your vehicle, of course.

This HiT-only design is a one-of-a-kind patented structure that you can only see in Dr.Pulley HiT clutch."
