VELOCITY STACKS CRF250 CRF450 PROX 38.VS1001. The latest generation of MX bikes is brought to market using electronic fuel injection. The majority of the OEM throttle bodies are designed for higher RPM horsepower. However, this is not the best set up for all tracks and riding conditions. ProX now introduces the Velocity Stack! The ProX Velocity Stack is an alloy tube that needs to be installed in the throttle body of the fuel injection system. The lightweight alloy tube is specially designed and developed to adjust flow so that the engine gets improved bottom power.
