In singapore, the ktm400exc and the 98`wr4 is been legalise on the road. sadly the dealer only bring in the 98 wr4(Aust), sadly still no mods(exhaust pipe) allow on both bike due to traffic regulation. i know that the ktm is ready out of the crate but it is a rfs, durability is still a ??? Is wr4 engine/gearbox/piston durability comparable to xr4 and ktm on the road? Riding 50%trail 50%road. how much hp on the 98wr4 stock.
