A friend of mine has a good collection of BSA parts and he recently went through them looking to assemble an A50 project. While he was doing that, we noticed that he had two differnt types of swing arms. One style was 2" shorter that the other. Is the A50 arm shorter than the A65?

Thanks,
Doc

The early closed loop frames had a shorter swing arm than the bulk of the open loop frames. Those swing arms are set up for fully enclosed chain guards (mostly) and RH brake anchor.

I believe some early open loop frames may have had a shorter swing arm as well. I have read some references that early Cyclones had a shorter swing arm, possibly a few early Hornets as well.

Thanks, I recently read a magazine article on the A50 that said they all had the shorter arm. In the same article, they said a few other things that I know to be incorrect so I was not sure if I believed them. Your explanation makes a lot more sense. My friend has two early frames which would explain why he has two short swing arms.

Thanks,

Doc

If a magazine article is written by someone with technical qualifications in a area related to the topic then it has a 90% chance of being correct.
IF it is written by some one with journalism qualifications then it has a 50% chance of being .
If it is written by a company hack then it has a 1% chance of bearing some sort of obscure relationship to the truth.
