First Look - The All New 2017 KTM 250XC-W & 300XC-W motorcycles


First Look - 2017 KTM 250XC-W & 300XC-W

KTM's 250 and 300XC-W 2-strokes are almost here. Massively redesigned and updated for the new model year, here's a look at what the new models have to offer...

The new KTM 250XC-W is the perfect package for all who love ripping performance, but don't want to lose control of their budgets. Pound-for-pound, punch-for-punch the compact 250 has always been one of the best fighters in the world of off-road, forming the ultimate fighting machine against more complex 4-stroke rivals.

All muscle, no fat. This 2-stroke machine is as lean as it is keen. With an unbeatable power-to-weight ratio, low purchase and ownership costs and straight-forward 2-stroke technology make the 250 a prime choice for extremely heavy off-road duty. Best-in-class performance combined with a perfectly geared six-speed transmission and a DDS clutch turn it into the absolute top dog of its class.

For those who want torque by the bucket loads, huge top-end power and a lightweight chassis ready to rise to any occasion, give the powerful 300XC-W a go.

For MY 2017, KTM underlines its continuous commitment to 2-stroke technology by thoroughly re-designing their 2-stroke power plant. An all-new architecture with a new shaft arrangement ensures even better mass centralization. Then there is a new cylinder with a twin-valve controlled power valve, a new counter balance shaft and plenty of other first-rate, newly designed peripherals. The crankshaft's 72 mm stroke remains the same, but otherwise, the component has been fully re-designed, which includes re-balancing and a counter balance shaft to reduce vibration. Compared to the SX motocross engine, it has more inertia due to a heavier ignition rotor. This helps the rider gently feed in the power for maximum traction in difficult conditions.

With a design to reduced rider fatigue, the new engine creates room for a lateral counter balance shaft. The impressive result of this is drastically reduced vibration levels, lowered by 50% on the handlebars and foot pegs.

Furthermore the engine's power delivery can be adjusted to track conditions in seconds by swapping between the different supplied power valve springs. New water jackets in the cylinder and head will take care of excess heat in any situation, while the revised lateral cylinder head brackets ensure fewer vibrations are transmitted to the frame via the two lightweight head stays.

The high-tech, lightweight chrome-moly steel frame is the base of the XC-W's handling, ride-ability, precise cornering and excellent stability. Due to wider but lower profiles for the steering triangle combined with hydro-formed side tubes, the torsional rigidity was raised by 20% providing more cornering and track stability.

At the same time the longitudinal stiffness is reduced by 30%, which results in better absorption of the impact energy from the suspension. In short: more comfort and less rider fatigue. Two threaded inserts in the lower cradle tubes make a rugged mount for an optional skid plate. In MY 2017, the XC-W frame is 300g lighter than the predecessor and a full kilogram lighter than that of the lightest competitor.

The all-new WP XPlor 48 upside-down fork is a split fork developed by WP in close collaboration with KTM. While it has springs on both sides, the damping action is split between the fork legs: compression on the left side, rebound on the right. The forks are easily adjusted for compression and rebound by twisting the individual dials on top of the fork tubes (30 clicks each). In addition, a longer and sealed hydro-stop guarantees better resistance against bottoming-out.

Due to high-quality materials and a state-of-the-art production process, the new XPlor 48 forks with some 300 mm of travel combine outstanding response and damping characteristics with weight savings of around 200g over the previous generation of forks. In addition, a new, optional pre-load adjuster allows to quickly dial up one of three different spring pre-load settings without any tools.
