KTM/Rudi SchedlA set of 17-inch wheels with street tires and a firmer suspension is all you really need to transform them into genuinely fun little motorcycles. While this might be forgivable on the dual-sport model, it really is a bit of an oversight for supermoto riders. Anyone coming off another street bike with six gears will constantly be shifting up into nothing. The KTM 390 SMC R might be the one exception, but the main reason it is so affordable is that it makes use of a slightly heavier street bike chassis. It backs up respectable performance with a dynamic, adjustable chassis setup, Japanese reliability, and street bike service intervals.
