Pro Series 2 CNC Launch Control

RFX Hardware Pro Series CNC components are designed, tested, and manufactured for the serious competitive rider.

Using our 30 years of racing and engineering experience, we've combined quality designs, superior materials, and precision manufacturing processes to create factory racing parts that are available to everyone.

RFX Launch Controls allow you to lower and lock the front suspension to stop front wheel lift under hard acceleration off the line.

The new dual-knob design allows the rider to choose the best fit for different riding conditions. The new dual-knob design also features a new plunger that's milled further out for more clearance on the new KTM models, but also has extra reach to ensure maximum lockout.

The new hinged latch design eliminates snags on the back of the fork guard, as the rear bolt has been replaced by two smaller bolts at the front. The new, deeper-positioned latch prevents the bike from being accidentally pulled off when passing the starting gate. The hinged design also allows for easy installation.
