Vintage Dirt Bike Q & A

http://www.joeabbatescycletherapy.com/images/examples/Copy-of-P1010009a.jpg I have one of these in a box of parts I got with a 76 cr250. Can someone please tell me what it is. Its aluminum and very light. Thanks

Looks like either a Thor or Cross-Up arm. Does it measure out to be a 250 or 125??

For the naxt two weeks I'll be moving from WA. to San Diego. I will take pictures and measure it. There is a differnt aluminium swingarm thats on the bike now. I will take pics and measure it too. I dont know what it is either. Thanks.

Welcome to San Diego. I also live in San Diego in the La Mesa area.

Stay in touch.
Take care.

Thanks, I just rented an apartment in Spring valley. Its just temp unitl we close on our house in wa. me and the wife are looking to buy a house in San Diego area. house prices in SD I bought two bikes at the flee market in Point Loma. One was the 76 cr250 and the other was an 80 cr 250. Neither bikes are complete, but I did get alot of extra parts. I was looking around on the net last night and I think I found out what kind of swingarm is on the 76 now. It looks like a 78 rm swingarm. Would that be legal for AHRMA racing PV class?

Spring Valley is next door to La Mesa. Good luck on your house hunt Calif is expensive but has the best beach babes around The RM arm should be legal on the CR125 for Post Vintage. Come on out to Barona this Saturday the 26th for the local Vintage Club practice! 30 min or less from Spring Valley.

I would like to go to Barona. I know where it is, but I will be in washington loading up a uhaul this weekend. And driving down next week. What is the local vintage club? Do you have a web site for it? Thanks Ron

Can someone look at the bike of the month for feb 2005. That is the swingarm I have. Infact that is the bike I bought, only now it is torn apart and missing the tank. Does anyone know what swingarm that is? Thanks Ron

Sorry, I can't help on the swingarm, except to wish I had one like it !! Can you tell what type of muffler that is??? I want one of those too and might be able to afford that, at least.
