Spirited, straightforward twin that mutated into the GPz305. Engine suffers top end hassles from 20k on if oil changes and maintenance neglected, with even the big-ends going. After 50k both engine and chassis knackered. The odd one reinvigorated with a newish 305cc engine but most dross now. Later models had belt drive (lasts 10 to 20k) and Unitrak rear end (needs yearly grease). Be careful of the engine as it goes off very quickly.
