Tuned 600 with twin carbs, high compression pistons, big valves and radical valve timing, produced too much vibration above 70mph but roars along very nicely. Slimline frame’s just as good as the Wideline whilst allowing improved comfort and styling. Rods, pistons, big-ends, main’s and valves can all go if the engine’s really thrashed but modernized, re-engineered motors have sorted these hassles. Good, bad and ugly bikes on offer.
