Best for: Pure competition motocross. Built to blast berms, launch jumps and dominate off-road tracks - no compromises for road or trail-riding use.
Built for: A raw, explosive 490cc two-stroke thumper - notoriously wild power delivery and vibration. Light, nimble and intimidating, an old-school motocross brute.
Not ideal for: Not for beginners, commuters, or anyone wanting road/street use. No lights, drum rear brake, no passenger provision and zero comfort for touring or daily riding.
