2013 KTM 350 XC‑F: PERFORMANCE OF A 450
Back to Bikes Next Benefit
REVAMPED ENGINE
The advantage of the KTM 350 XC‑F has always been its weight. And now the bike's heart is even lighter. Another 500 g (17.64 oz) and more have been lost thanks to the new die-cast housing. The extremely short-stroked DOHC power unit, equipped with the latest generation of EFI, excels with its even wider rev range and exceedingly efficient rideability. And, just like all KTM four-strokes, it can be activated with an electric starter.
CYLINDER HEAD
The modifications to the 350 cm³ (21.36 cu in) DOHC engine can be summarized very easily: more power at less weight. Flow-optimized ducts supply greater gas flow and better cylinder charging. Strengthened valve heads and valve seats plus valve springs with a higher spring force make it possible for the lightweight titanium valves to withstand the increase in maximum engine speed from 13,000 rpm to 13,400 rpm. Or more simply said: more power for the new 2013 KTM 350 XC‑F.
CRANKSHAFT
Factory bike or production bike? The crankshaft on the new 2013 KTM 350 XC‑F is equipped with a revolutionary plain bearing in the lower conrod eye. In conjunction with the stiffened crankshaft and a lighter piston, this design is a key prerequisite for increasing the maximum engine speed to 13,400 rpm and the impressive peak performance of the 350 cm³ (21.36 cu in) engine. But not everything revolves around pure power. One major benefit is an extension to the service intervals for the crankshaft; a benefit in terms of time and costs.
