It seems like it. At least for now in California.
So far, half way into the 2011 moped racing season I’m starting to have doubts that moped racing will make a come back to California this year. It’s a little disappointing. There’s no moped racers to compete against. I was planning on going to the race #6 at Buttonwillow August 20th for the SoCal vs NoCal event but I have little hope to see a lot of moped racers there. I can always race in the mini gp motorcycles class again but it’s not as fun. If I skipped race #6 I might go to the race #8 October 15th at Grange’ just for practice with few friends.
After reading Will’s comment on my blog, I’m starting to turn my eyes on motorized bicycle racing (2 stroke, 4 stroke and electric) that seems to be taking off. The organization will be at Grange’ for their next race October 22nd. I don’t think that any of my fast 50cc race mopeds would blend with those guys on the track but I might bring my motobecane av10 and just check out the event. It seems like they’re having fun rubbing elbows with at least 15 bikes on the track. Why not getting one of those 2 stroke motorized bicycles and bring my moped tuning skills to the game? They seem to care about aesthetic too with a best in show award. That could be a fun, cheap and revive my motivation for 2 stroke racing.

My white Motobecane Av10 49.9cc race moped (stock cases + 19 carb) at 66 mph uphill with a 56T rear sprocket.
I finally bought a GPS to find out the real top speed of my race mopeds. In the video, I don’t know what happened at the end of the ride but I focused the camera on the wrong reading maybe because the sun was blinding my eyes.
I made another video of the ride downhill but I ran out of battery and gasoline so I wasn’t able to read the top speed either. It felt like a solid 70 mph though and got a little scary with such small tires and no steering damper, plus I was worried about the traffic, radars, turns, etc…
I’m now confident that the bike will reach 75 mph with smaller rear sprockets. Next time I’ll try a 54T then 52T and probably a 45T. I’ll have to drive up north in the Valley outside LA and find some long straight roads with no traffic this time to be safer. I already know a sweet area.
I can’t wait to test my other faster race moped, the yellow Peugeot 103 Rcx 49.9cc Bidalot H2O 14,000 rpms (malossi cases + 21 carb) with a small 53T rear sprocket instead of my 74T sprocket currently 65 mph. I’m hoping to reach 80 mph with that bike.
It’s time to adjust the chain! Loose is good though, less friction, less resistance, more speed… Not recommended on puch or tomos bikes with small sprockets. Keep it a secret and switch to french variated bikes 😉
Like my buddy Shaw the moped guru would say as a joke: ” That’s some race shit! ”

Transmission 11 x 56
Estimated 70+ mph downhill:
Updates after the test ride:
I installed a smaller 52T rear sprocket for faster 70+ top speed on flat road + a clutch pulley for fast take off and idling. I’m using a modified heavy duty doppler clutch pulley with 8mm custom made pins and a custom triangle shoe brace. In the future I’ll probably replace the doppler er3 variator with my better Bidalot junior variator. The next test ride should be really fun and scary! Now I wish I had better mag wheels and bigger tires. It was a side project built within strict 50cc race class rules using cheap old parts to show that it was possible to build a race variated moped with a small budget and no French high tech racing parts.
I’m tempted to remove the fairings and the air box, mount a regular seat and a round head light to make it look more like a street bike since I’ll be riding the streets more than the track. It could look cool.
