Racing classes in the US

Hi,

I was talking to a racer at the track yesterday and we discussed PB racing in different countries. I know next to nothing about PB racing in the US.

Can you tell me a bit about it or suggest some good reading? Are there uniform rules across the nation or is the racing and their respective classes different from state to state?

Regards,

A lot of the groups here use rules based on the european rules.
Most organizations run
a stock cag/2.5 class,
a modified cag/2.5 class,
production class (40cc 3 port engines, production pipe, standard crank, 14mm carb, no internal modifications allowed),
super production (40cc 3 port engines, race pipes, race crank, 14mm carb, no internal modification allowed),
Open (40 or 50cc 5 port engine, race pipe, race crank, any carb, internal case work is allowed),

OK, thank you! Now I know and can tell my friend next time we meet at the track.

classes go like this...

stock 2.5 class(cags and 2.5s)
modified 2.5(modified)
4.2(stock series I polini motor, any tire, 17.5mm restrictor, 14 mm carb)
Super production(any polini seriesII motor 3 port,any production pipe,14mm carb, any tire, 6.2-10.5hp)
open pocketbike(open 40cc or 50cc 5 port motors, BZM or polini, any pipe, any tire, any carb, unlimited modifications)

rules about safety gear should be the same..

track rules should be the same..

Flags are the same..

-green flag: GO!!!!!!!
-yellow flag: caution..rider down..no passing under yellow flag
-red flag: danger..pull over to the side of the track..await assistance
-black flag: u are disqualified..u must leave the track due to unsafe riding or bike malfunction
-white flag: final lap
-checker flag crossed with another flag: race half over
-checker flag:race over
-blue and yellow flag: u are a lapper! move over a faster rider is approaching or passing

Who are teh recognised racing body(s) in the US? Is there an US National series?

I race at a club in Colorado and we are looking at getting in to the bigger picture (what ever that is). Is there any series where local points go towards national events or finals?

Thank you all for your replies in this thread and m14cus I hope someone answers your question to.
