Crazy little stroker that rivals Kawa triples. Pistons, gearboxes and main bearings major problems. Heavy vibes indicate imminent crank failure; thrashed examples last only 12k. Poor acceleration may be clogged silencers as they need cleaning frequently. Swinging arm pivot seizes in and seat splits. Worn suspension causes wobbles. Pirelli tyres help. Several still left on the road and stock rebuilds can last for 20 to 25k
