Riders and the media were excited about the prospect of a lighter and easier to handle open-class machine when KTM’s 350cc project was publicized. When the bike was first revealed, the motocross media said it was only slightly lighter than the 450 and had much less torque, running more like a fast 250F. Still, the machine has won motocross races all over the world, plus KTM had considerable success at off-road races with riders aboard converted 350SX motocross bikes.
2012 KTM has done the off-road conversion, with a wider-ratio transmission and engine modifications that make the aggressive powerband more appropriate for off-road racing. The new frame uses the non-linkage WP PDS shock, which KTM swears works better off-road. A host of improvements to the clutch, engine cases, fork, tripleclamps, rear suspension shock position and ergonomics highlight the major changes. KTM also improved the electric-start system and added a more powerful 190-watt electrical system to power FIM enduro-legal lighting. The new exhaust is spark arrested and quiet, and the tamper-proof EFI settings ensure EPA and California 'Green Sticker' compliance.
The hydraulic clutch uses a new diaphragm-type single spring, which is adjustable for preload. The light pull and progressive feel are excellent. Despite EPA-compliance, the 350 has sharp, instant throttle response and a satisfying yet quiet exhaust note. The electric starter fires the bike up pretty quickly, but to be honest, the bike starts faster when you use the kicker.
One thing is for sure, nothing about the KTM feels cheaply made, and everything is designed to be functional.
