Im goin to be racin the CMA Flat track circut this year and I still need some parts and info,does any one know what is the best size and make of tire for speedway and 1/2 mile tracks on a 86 TRX250R what rubber compound and tire presures ?any help at all would be great thanx

 

The answer to your question is not an easy one. Every track you go to will need a differant set up. Softer tires, wider stance, shorter swing-arm less jack in your sway bar.

This is the reason that you hear people say that set us 90% of the game. For a starting point yry this.

18x10x6 Mcreary SD23 compound fronts
18x10x8 Mcreary SD38 compound rears
Sway bar set to neutral (crank on one side of the sway bar or the other in order to make the rear tires weigh the same you will need bathroom scales to do this)
-2" swing arm ( 2inches shorter than an '88 4trax or 3 1/8 inch shorter than 86/87 4trax)

Other than that its up to you and how good you can read your quad and understand the track. As a general rule for circle track races your gonna want to put some jack ( more weigh ) on the front right and left rear.

Good luck the learning curve starts now...
