TBParts Vintage Z50 versus CRF50 88cc Class Confirmed for 2012 GEICO MiniMotoSX
Back to the roots of Minibike racing
Irvine, CA. (February 7, 2012) Most active Minibike racers got their start on either the Z50 or Honda XR/CRF50 so they are considered by many to be the roots of Minibike racing. has been in business for over 15 years and still sells a lot of parts to people that enjoy riding and racing the “older”, smaller bikes so they have stepped up to sponsor the classic classes for 2012. Each class will be limited to just 10 entries on a first come first served basis so if you are interested in racing at the biggest MiniBike race in the world, you better act quickly.

You can get the complete rules here: 2012 MiniMotoSX Rules

Entries are NOW OPEN and are available here: 2012 MiniMotoSX Entry Form

Make your plans stick around in Vegas during the Monster Energy AMA Supercross weekend to get on the track yourself and race for an AMA #1 plate. You can find race entry and event info at Ticket information:

What kind of chassis can you run in the crf 88 class? super pro, stock a- style? I'm ready just want to make sure
I'm in and it's a done deal!!!!! +35 and crf88 class no turning back now . Time to build an 88 and plan a trip.
Is the 88 class going to be checked for true 88cc bikes? I would hate to come all that way just to be beat out of a position from a cheater?
Yeah those boys both haul, I don't expect to win but hate being beat by cheaters. I'm de-tuning my 115 back down to an 88 just for that class and I hate doing it,lol.
The rules don't say anything about Fuel Injected 88cc with a little shot of hidden nos for the hole shot. Or an 88cc nitro methane with methanol or alcohol burner.

Dang they did put it in the rules.............Fuel Gasoline ONLY No Nitro, Alcohol, Methanol etc. LOL, But nothing about fuel injected or nos
Lol a little nos would get my big ass moving off the gate!!!! Tore the 115 down with a tear in my eye to make an 88 but should be fun revving the heck out of it.
