Just as gearing is a trade off between acceleration and top end speed, a static height velocity static is a compromise off at what RPM range the engine will perform best.   This Gabro Racing Team Variable Velocity Stack Kit eliminates that issue since the height of velocity stacks will change while you are riding.   The velocity stack height adjusts while you are riding so it is provides the best horsepower and torque throughout the entire RPM range.    This kit requires a variable velocity stack specific map to be flashed, a promo code to get the map for no additional charge is included (UpMap T800+ for Aprilia required to flash the map).   It is recommended to use a Sprint high flow air filter with this kit which is available for purchase through CBC Motorsports.

This variable velocity stack kit is intended for Race Use only and is not considered Street Legal.
