Classic looking stroker twins with reasonable handling and lots of go but piston seizures, rebores, gearbox and oil pump failures. Failure of the big and small-ends also caused much mayhem. Quality of the engine rebuild and the rider’s right hand twitchiness determines longevity and reliability. Rarer 350 best buy.
