jock Kerr used to do a 180cc kit for the CB125, must have been great fun while it lastedmy mate had one with a Jock Kerr 400cc conversion.
Used Hillman imp pistons.
he though he was a fast kid - until it came to a corner![]()


A 1956 NSU 250cc Supermax. It's tidy and runs well. Just needs a bit of finishing here and there. Amazingly good brakes though for the age of it. It's got an unusual overhead camshaft which is driven by a rod/crank in a similar way to a steam engine's wheels. 
Wrote off my new G5 back in 1986 so last year acquired an identical full nut & bolt restoration (after having some liquid refreshment) None of the cam problems which affected many of these bikes although it's low miles and I will probably only add about 1000 miles annually.

Lovely restoration job on the Indian, but why the "Hipster Bobber" tyres and shorty mudguards? They ruin it IMHO
Could have been worse I suppose - exhaust wrap anyone?

That's a very nice restoration he's done there Andy,
I have a few spares knocking about somewhere, not a lot, but he's very welcome to them,
Cheers Graham

He has based it on an Indian dirt track racer:
I was helped by Paula of course, as a Commando was the first bike she ever rode pillion on. It's been covered in some sort of gooey protective spray (not ACF 50) and needs a good spruce up but, as you can see from the photos it' starting to look very nice. With a Z1, CBX1000, GT750 Kettle, R90/6 my 1970's collection is almost complete!. It was a great and very exiting era of motorcycling band I'm enjoying every moment spent on them.
