Rear Swingarm, Disc
« on: March 23, 2021, 02:54:44 PM »
My bike came with this disc conversion? Consisting of a Lester Mag wheel, rear disc caliper and swingarm.

Anyone got any idea where it is from?

I'm building a CB550 and deciding whether to keep it or sell it on.

If it's got tits or wheels, it's hassle, if it's got both, RUN!!!

Yup F1 swingarm with 550 wheel, get a 500/550K swing arm from 71to 76

It’s a 750F1 swinging arm with a 750F rear wheel Bryan, the 550 has a rear drum, clearly the PO fancied discs all round for some reason or maybe they fitted what they could find when the liner cracked on his original wire wheels.

Didnt notice te disc fittings, looks an odd pattern, looked like a drumed lester at first glance
