Yeah it is a twin with a whopping 14.2bhp if I recall
. The bike weighs about 164KG too so it wasn't a rocket ship but I did see 80 once or twice.
I never had a problem with the reliability what so ever but I only had it for 3-4 months while I was learning then passed and then sold it for a fazer.
It's loosely based on the GS500 frame wise, that fuel tank was whopping too, the bike felt very big for a learner bike but it wasn't a very
good ride. Suspension was too firm.
Dunno if you would call it a reliability issue but the fork stanchions seemed to like pitting.
