smelling123 Posted January 1, 2014 Report Share Posted January 1, 2014 Would anyone be kind enough to post some close up pictures of the swingarms fitted as an option to the 340s by comerfords please? It would be inetresting to know length (pivot point to wheel spindle centre) too. I am looking to make one for a ratty 198b I have in bits as a spring project. many thanks in anticipation Stu 2 Quote Link to comment Share on other sites More sharing options...
woody Posted January 1, 2014 Report Share Posted January 1, 2014 Don't forget that those bikes had the pivot point moved forward so if anyone does come up with the length of the swingarm, you need to also know how far forward the pivot was moved. The same length swingarm on the standard pivot would probably be too long. Commerfords only did this conversion to the 340 models, but there was a 198b that was also done at the time by Reg. It was a special order by the customer that purchased the bike from them and was the only genuine conversion to a 250 model Quote Link to comment Share on other sites More sharing options...
smelling123 Posted January 1, 2014 Author Report Share Posted January 1, 2014 Thanks Woody, all understood, my intention is to move the pivot forward too - I think I can go about 15mm without having to machine the cases but I havent taken any accurate measurements yet just started looking. I wanted to know if the comerfords arm and pivot mod ended up with the same wheelbase as the standard bike. It'd be nice to see/measure one in real life if anyone is feeling kind..
