Stage6 Quick-Action Throttle SSP. Quick action simply means that it takes a shorter stroke, and in turn reduced wrist rotation, to go from zero to wide open. This is particularly advantageous when using larger carburetors - the slider can be moved quicker, which might give you the milliseconds you need to win a race.
The grip is made of CNC-milled aluminium, definitely a state-of-the-art product with flawless finishing. Several lock-in wheel positions inside the throttle mechanism and an adjustable throttle cable ( included) provide sufficient settings for different carb sizes and set-ups.
THIS IS NOT A DIRECT FIT FOR ALL BIKES. This system is intended for guys doing custom builds, etc, do your research on the style you need for your build.
