Alternatives to the race replica 600’s which go almost as well for most of the time, though benefit from a suspension upgrade. Plenty about with low mileage and in nice nick but the odd one thrashed, crashed and bashed. Tough engine but finish goes off after three/four years. Rear mono-shock bearings often shagged after 20k and electrical hassles around 50k. Some have done 75k plus.
