After riding my 84 RM125, which has had the magic wand waved over it, i thought that it was pretty quick, untill i rode this one. Bottom end does not exist, but mid range and top end are beyond explanation. Sounds like a 250 and explodes like one.
Engine wise there are more factory bits than you can poke a stick at. It runs a heavily modified 39mm carburettor with a factory works pipe and muffler. From the factory the bike would have been fitted with a single left side radiator whereas this bike is fitted with twin radiators. Suspension is nothing like i've ever seen or ridden on before, specifically for something built in the early eighties,
I'm not 100% sure of the exact origins of the bike although a certain Queensland Kawasaki collector may know more but i was of the understanding that it came out of Europe/UK some time back.
