Flat Track Quad Racing has a lot to do with handling and being able to adapt to changing race conditions.
In order to be legal to race you need a tether switch and nerfs bars. Next would be numbers and number plates. You need a plate on the front bumper and rear grab bar plus numbers on your rear fenders and front hood. Some other quad modifications are listed below:
Basic Quad Modifications:
Tires and Wheel Choices
- Typical tire sizes are 18x6x10 for the front and 18x10x10 for the rear. A wheel thickness of .160″ or above is best for strength and safety. A 10×8-rear wheel is tougher to use because it causes too much tire rollover.
- Tire Compound – For an amateur rider a good starting point would be a SD-33 compound front and rear for American Racers and a T20, D10 front and D15 rear for Hoosiers.
- Air pressure is next and depends on track conditions. A good starting point would be 8psi in the front and 6psi in the rear.
- Sway Bar – The function of the sway bar is to keep all the wheels planted on the track for optimum traction.
Advanced Modifications
Suspension: Lowering your quad’s suspension will greatly improve the handling. Either this can be accomplished with aftermarket lower kits or lowered shocks made for flat track racing. Next would be an adjustable axle and wider a-arms. Both will help tune your quad to track conditions and improve handling.
Engine modifications would be last. For a 4 stroke, a pipe is the biggest mod you can make on an engine. The same goes for a 2 stroke. Next would be things like a cam (4 stroke), porting, high compression piston and aftermarket ignition.
