The B25 gearbox was a pleasure to use despite the slightly long travel at the lever. These machines were designed to be revved hard with the redline being at 8000 rpm. Ouch. Compression ratio was 10:1. Needless to say, many didn't survive that sort of high rpm running.
I had one as a teenager, lovely bikes.
love the sound of it
