2017 KTM 350 SX-F
THE ULTIMATE COMBO
Since Tony Cairoli first took a 350 SX-F to the top of the MX1 World Championship in 2010, the Red Bull KTM athlete has dominated the class aboard this nimble but powerful bike with five consecutive World Championship titles. No surprises here, with the combination of 450-class muscle and the agility of a 250. Who said you can’t have everything?
Features may include:
- 99.8 KG
The main target for the KTM engineers when developing the SX models was a massive weight reduction compared to the previous generation. The result: the current SX-F models are the slimmest, lightest bikes on the track. Even though the 4-strokes are equipped with an electric starter as a standard feature, while the competition still needs to be kick started, the SX-F line weigh in pounds less. Rather than kicking to start – you can focus on kicking ass.
The airbox design offers maximum protection of the air filter while ensuring maximum airflow. The large twin-air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a face full of mud. Without tools. In seconds.
The high-tech, lightweight chrome-moly steel frame is engineered for excellent handling, precise cornering and supreme stability. You can also count on high torsional rigidity and low longitudinal stiffness for better absorption of the energy created by the front and rear suspension sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight engine head stays contribute to a reduced vibration level. Two threaded inserts in the lower cradle tubes allow for an optional skid plate. The engineers were able to pull off all that, while making the frame two pounds lighter than that of the lightest competitor on the market. In addition, the frame is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light aluminum subframe, which weighs in at less than 2 pounds.
Sophisticated å«No Dirtå« footpegs prevent clogging of the footpeg pivot, even when digging in deep ruts. Looking for a higher riding position? Then just mount the footpegs of the MY2017 EXC models, which are 6mm higher than the SX versions.
You can’t brake any harder, better, faster or stronger. These high-tech Brembo babies are combined with lightweight wave discs made by Galfer. For 2017, the rear brake features a 10mm longer brake pedal and you get new, less aggressive brake pads all round.
KTM engineers sure know how to handle handlebars. This tapered one, made of high-strength aluminum by NEKEN, is fixed in damped rubber mounts and has two different positions. From 2017 onwards, the lower handlebar clamps are separated, while on the upper side a new bridge-type clamp guarantees more torsional stiffness. It’s also easier to replace the bar in case it gets twisted in a nasty crash. ODI lock-on grips make grip changes easy which does not require any wire or glue to be secured.
Noise limits are a real challenge for every manufacturer. Therefore, KTM has put a lot of effort into the development of its exhaust systems. All 4-strokes are fitted with header pipes that have a unique standard feature; an additional resonator system ÛÒ a small chamber connected to the pipe. All 4-strokes are fitted with a short silencer, mounted as close to the engine as possible for mass centralization and better rideability. Its advanced internal design reduces the noise sufficiently in order to sit safely below noise limits while still raising the hairs on your neck.
