SoCal Motor Bicycle Racing Sat Oct 22nd 2011 Grange Racetrack

Cool! Thanks for the link MBR. Man that looks like too much fun. In the 2 stroke class what is the most common engine used?
Yes, it really was a lot of fun but this next race is going to be off the charts!

The 2 stroke class is only Chinese bicycle kit motors and the vast
majority were 66 cc powered also commonly misnamed 80 cc.
I didn't keep track but there had to be a few 49 cc motors there.

Another not so common size is a 55 cc but they are all look about
the same even though they are made by a few Chinese factories.

There are no rules or limits on engine modifications on this motor class
and there were a few Sick Bike Part shifter kits.

The only other 2 strokes at the Willow Springs race were 5hp, 9 hp and
11 hp Morini's.

Did you see the updated Motor Class list in a previous post?
There are a few other 2 strokes people have used on motorized bikes.

The pocket bike cag motors and the GP 460 would make great racers.

Cool thanks. Just thinking about what I might wanna use when I can step up from my 25cc weed wacker jobber. I think I had a GP 460 on a goped. Thing hauled ***. Too fast for those little tires.
 
Speaking of 2 strokes the big question before each race is if my mate
sifab is going to show up with his radical water cooled 11 hp Morini. :D

A member on this forum @kawasaki999 has hit a GPSed 55 mph on a
GP 460 driving through a rack mount Golden Eagle belt drive.

He had an expansion chamber on the 47 cc 2 stroke.

Here is a great video of SuperMotards racing at Grange Track
riding on the asphalt and the off road dirt section.

I don't know if we are going to ride on the dirt section or not?

That is one fun winding strip of blacktop!
Only 51 days until we all get to ride it!
