The NX 500 was the smaller-engined sister of the NX650 Dominator, sharing its frame, styling and RFVC air-cooled single but with a 498 cc engine for markets where insurance or licensing favoured a smaller bike. It is a road-going trail bike rather than a hard enduro, with a 21-inch front wheel, disc brakes front and rear and both electric and kick starting on early bikes.
