Pat 850T beating Chris 850n/a (both have clutching)

  • Quicker backshift
  • Strongest engine braking
  • More track speed
  • Pulls hard to the finish

Here is where you're going....

You made it...

I love the smooth engagement to feather the track to get unstuck.  Its the strongest engine braking I've ever felt. 

A test guy said to me "I could stand up and drink a coffee coming down this hill haha". 

Opposite of that, crack the throttle and BANG....7900~8000 rpms, hang on. 

The kit digs deep, pulling out all the muscles from the engine.  It has the ability to make them useful not only wherever, but however you run your sled.

Tight connection between your thumb and snow.  Drive the clutching as smart as you want.  A tree rider's delight.

Throttle control
Feather smooth engagement for slow, wrong foot forward.  The handlebars dont surge, tugging on your hands.  After you made it, blip the throttle, time it right, do a victory wheelie.  You'll burst more track speed for the next climb.

Pulls hard
When you want to drive more aggressive, the feeling is like having a gigantic hand on the front bumper, pulling you up even the steepest hill. "woo hoo" and then its holding the sled back with strong engine braking coming down.

When you need the power to overtake your buddy, there is more power on tap to speed up and pass.  30mph side by side breaking fresh snow, full throttle, pull away strong to the finish.

Good mileage
Drive the clutch kit with the same fuel economy as stock clutching, most times even better.  With the low revving at part throttle, high torque feature when you need to drive for fuel economy on the way out >> Drive it gently and you will be rewarded with lower fuel consumption at part throttle, arriving back at the trailer.

There is more engine power under your thumb, just waiting to be used.
