Would need to have at least 15 to 20 Mini Bikes to make
a class with two 5 lap heats and a 12 lap final race.

How many of you Mini Bikers also have Motorized Bikes?

Were any of you guys at my first race on June 18th in
Willow Springs, Rosamond, CA?

It looks great Neil! I,ll be there. And I am sure allot more will to?. I,ll be getting a motorized bicycle going also,
Any chances of us doing some supermoto also? either during are race or another seperate race?.

Not only would it be FUN!, But we could actually say we have raced SuperMoto on minibikes which we have never done yet!.

And May be a Drag Race Exhibition? If you had time it could possibly make you more money??$$

Lots of minibike Drag Racers lately!

No limits on motor modifications, Shifter kits are ok,
No real motorcycle tires allowed. Bicycle tires only.

3) 2 Stroke:
48 cc to 66 cc aka 80 Chinese bicycle motors.

UNLIMITED Gas OR eBike Class
Includes any motorized bicycles that are over 12 hp and don't
fit in any the other classes but meet a few basic common
sense rules like functioning pedals and still resemble bicycles.

Multi speed shiftable motorcycle engines are in this class.
Motorcycle tires are in this class.

Exceptions may be made to the above classes at the race
organizers discretion [That's me] and the list will be updated as needed.

Racer's feedback is welcomed to define these classes more.
