It does have a lot of similarities with the 200 , the tank and cable operated front disc brake being the most obvious but it has left side cam chain engine. The closest to it is the CB125 K5 but there is a difference in the external shape of the cylinder head which was only used on this one model. The K5 had a rounded cam chain chamber and points cover. On the B6 they're more square so a different head would mean different points and tacho covers etc. As best as I can tell from image comparisons its the only difference in the K5 and B6 engines.

In all honesty I've given up on David Silvers , they don't even list my bike For the most part she looked good but almost every bolt/screw is rounded/stripped and the engine was a mess with re-used broken gaskets, half a gallon of sealant and pitting in the combustion chamber from moisture deposits. Not to mention someone had tried running the 6 volt system on a 12 volt battery. So far I've spent around £600 just on engine and electrical stuff, most of which has ended up coming from Indonesia. It would have been nearer £800 if I'd gone to CMNSL . I'm praying my attempt at polishing out the internal pitting has worked as I simply can not afford the minimum of £1700 for a replacement head (CMNSL actually want nearer to £2.5k for one!) at the moment . Saving for one would take at least 6 months Currently waiting on valves coming from somewhere over seas before I can rebuild the motor. Then it's time to try and figure out why the headlight blinks along with the turn signals..

Been riding on and off for around 30 years and just started my first project bike. Talk about a midlife crisis Living in God's Own County , Yorkshire and wondering why on earth I thought trying to rebuild a bike that's only 10 years younger than me was a good idea. Hoping to get some inspiration and maybe advice from more experienced folks on here. The bike I'm trying to get back on the road? A 1978 CB125 B6 twin aka CB125 JX Benley. Never released in UK or USA , believe mine was imported from Germany altho I don't know when. It was first registered in UK January 2023 and I'm the second owner since then.
