First Impressions: 2017 KTM 350 SX-F

Vital Review

KTM's 350 SX-F has been an interesting concept ever since its release. The initial goal, power closer to a 450 but with the characteristics of a 250F. However, the first release seemed closer to a 250F, so KTM went to work all around the bike, but mostly with the powerplant. Now things are a bit different, as the KTM 350 SX-F produces horsepower than nearly rivals its 450 counterparts. While here in the US, the 350 hasn't ever quite caught on with racers in the motocross scene, it has become popular with the weekend warrior crowd, along with the casual and serious off-road racer. So if the 350 produces near 450 power, what makes it so easier to ride? Weight? It's only a few pounds lighter, but it all comes down to inertia and how the bike feels. With a bore and stroke closer to that of a 250F, the power it produces isn't as brutal feeling as a 450. Along with not transferring weight as violently during acceleration and then when decelerating. All-in-all, the 350 is an interesting choice for any rider who's looking for something a little safer than a 450 to ride, but not give up too much power like when jumping down to a 250F.
