So I just bought a pretty much brand new 2005 trx90 for my daughter for xmas. With that being said we race motocross so I'm not a newbie to this life. We are switching to quads because she is not physically strong enough to race a 65cc motocross bike (myself 25+ years and my daughter 4 years with a title in boys 4-6 injected class) So since we love to race this is our new thing. So I'm needing help with where to find parts and which way to go with parts,tires and so on. We will be racing flat track dirt and racing the whole entire cycle city promotions arena cross circuit this winter. I'm willing to buy used used offset rims and tires, front bumpers, nerd bars or just advice so if anyone has some stuff laying around or what ever let me know thanks Chris

 

Well my soon to be poor friend, the TRX90 can be built into quite the runner. A full blown 90 motor will run you a cpl thousand. They use 50cc cranks and do all kinds of wild stuff.
And then there is the suspension to work on.
If racing mini quads is in your future, you need a Apex or DRR. Sorry.
Call Hetrick Racing for info for the TRX and others.
