This is a discussion on A little asian 50's action. within the General forums, part of the Caferacer.net Forums category; ...
I think I watched this same video just the other day. After seeing a NSR50R posted for sale on one of the message boards I went on Youtube odyssey for 50cc racing vids. I love 50s but sadly my fat ass is too big for them!
Thanks Nic. That was fun to watch. I love 50cc bikes, just wish some one else in uscra had one that ran in my c110's class.
I too am too fat for a 50, but down nearly 20lbs from last season. Now if I just got bigger balls, or retired so I wasn't afraid of injury. No work no eat.
II found the rule book will be looking it up. Thinking about though I have always wanted to race the 125cc strokers.
I really need to just get my shit together and race again.

5.4.1 Classic 50cc GP
Machines are to be prepared in the spirit of the early years of
international 50cc racing. The purpose of the class is to recreate
the period from the late 1950’s through the mid 1960’s when
many small street based motorcycles were modified to compete
in the 50cc class. Genuine works race machines from the period and
accurate replicas of works machines from that period may fall outside
the permitted modifications and engine specifications for the class.
Some machines acceptable from the period, but not limited to, are:
Benelli • Derbi • Ducati • Garelli • Harley Davidson • Honda C110, CA110
Itom • Kreidler • Minarelli • Mondial • Moto Morini • Sachs
Suzuki (Restricted: 4-speed transmission max) • Tomos • Zundapp
1. Engine: Air cooled engines only.
2. Displacement: 50cc.
3. Carburetion: Maximum carburetor size 21mm.
4. Transmission: Maximum 4-speed transmission.
5. Frames: Must be of tubular steel or pressed steel
construction with steel swing arm.
6. Suspension: Twin shock suspension rear - conventional each side.
Conventional telescopic or leading link front suspension.
7. Brakes: Drum brakes front and rear.
8. Wheels: Wire spoke wheels only. Rim size 17, 18 or 19”.
9. Tires: Minimum 2.00”, maximum 2.75”
I raced an RD60 in a YSR series in Boulder, CO back in '91. Unlimited fun - until your bury a footpeg. But the crash is mere inches off the ground and is at a speed that most folks would feel non-threatening to life and limb. I highly recommend it.
Caferacer.net - Come for the motorcycles, stay for Witworth's vast knowledge and wisdom that we should all heed without question. He (it) IS the smartest person (chatbot) in the room - just ask him (it).
Nic, as you probably noticed, there are several classes for 50's- classic, which mine runs in, super vintage up to 83 or so and modern.
Mb5's are popular in SV, and reiju, derbi and those Honda dream 50 replica racers ( which I want some day). Those are fast! George decamp does Very well on his and he is fricken 79 years old.
There is also the Cosmo Class- RIeju and derbies punched out to 70cc. Very fast.
5o 's are a hoot.
What 50cc class and bike would have a good mix of skill levels racing as well as track time opportunities cost is always a consideration.
