Need suggestions for TRX 90 performance CHEAP
 

Just got my son a 2003 Honda TRX 90 for $400..
ALmost like new just needs handle bars

I am looking for some fairly cheap upgrades I can do to it. Here is my want list

HANDLE BARS.. I am not sure what ones people recommend
EXHAUST- Must be able to be used in a state forest
WIDE A-ARM Kits I know there is a 300ex kit out there but dont know if it is the best option... most likely isnt
Wheels
TIRES
REAR end Widening
SHOCK upgrades

My son wants to try a race next year to see if he likes it before we buy him a DRR.. I know the honda isn't the fastest bike out there but it was cheap for him to start out with.

They come with a plastic cap over the air intake, to restrict it and keep things mellow for beginners. Most likely the previous owner took it off, but just in case check that it is not still there.......

This thing is like new... The had the throttle limit screw set all the way in.. IM sure they haven't touched much to gain any power... I will check that later today.
