in an Automatic Transmission. As Torque from the engine is applied to the Torque Converter, the internal workings  cause the torque output to be less than the engine Torque.  Less wheel spin on take off. The SPS Clutch Lever eliminates
stalling, improves traction,reduces arm pump, improves starts,increases corner speed, Puts more Power to the Ground in the most demanding situations, even if you are a novice racer or experienced , you will benefit with the use of the SPS Lever.

  Happiness Is Getting
        "The Hole Shot"
What it Does- and- How it Works
Using the upper Lever on starts or off the corners allows you to control the amount of Free Play in the  clutch cable causing the clutch to not completely releese. Using The lower lever  automaticly disengages the upper lever .
You can now control  Wheel Spin! Bogging, and excessive Wheelies!
Many motorcycle and ATV racers consider the start to be the most important part of a race, and it is particularly important in those forms of the sport where the tracks are very small, tight and difficult to pass on. This is particularly relevant in motocross where racers line up  alongside each other. Getting the Hole Shot is the difference between winning and loosing. The SPS Pro Start Lever plays a very important role on the line, allows quicker starts, less tire spin, lower 60 foot times.
