Slow and constipated triples able to run to 35k if left stock and the poor suspension didn’t have the rider off. Main’s seals and small-ends first to go but the gearbox output bearing was also a weak point (check play in the sprocket and also check for chain breakage damage). Also dodgy clutch, centre piston holes easily and exhaust studs break. 550 version marginally more useful.
