Early twin shocker needs suspension upgrade to handle sanely. Uni-track version needs yearly grease. Steering head bearings short-lived. Needs Phantom tyres. Engines start to give trouble after 45k, most dead by 65k. Also, exhaust, clutch, cyl head gasket, caliper and electrical hassles. Camchain tensioner can stick with loads of rattles. Motor flat below 3000 revs even when new but engine has reasonable power.
