Rider Profile

Best ForNote: the specifications provided are for a KTM 150 EXC two-stroke enduro bike, not the KTM 1390 Super Duke GT sport-touring machine named in the request, so this profile describes the enduro bike instead; it suits experienced off-road riders comfortable
PurposeBuilt purely for technical off-road enduro riding and competition, not for road use or touring.
Rider FitIts very low dry weight and tall seat height demand an active, standing riding style and reasonable rider fitness and leg length.
CharacterA sharp, high-revving two-stroke enduro weapon that rewards precise throttle control and skilled clutch work.
Not Ideal ForNot suitable for riders wanting a comfortable road-going or long-distance touring motorcycle.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
