Orange KTM 150 XC-W 2018 DIRT Bike

Minimal Fuss, Maximum Fun

‘XC’ means cross country. ‘W’ represents its wide-ratio transmission. ‘KTM’ stands for winning. This model is a race-ready bike built for closed course Enduro rides or races that don’t require a homologated motorcycle. And for riders who don’t want to drag around the extra weight that comes with homologation requirements. With the agility of a 125 and enough muscle to take the fight to the 250cc 4-strokes, this bike punches well above its weight. That’s why when the going gets tough, the tough get an XC-W.

Engine & Exhaust

The KTM 150 XC-W engine is the most powerful and most competitive engine in its class, providing precisely the kind of power an Enduro rider wants. This 150cc ripper has been developed with the latest KTM engineering know-how and the most advanced technology available. The results: whopping power and mountain conquering torque across the entire rev range, while being extremely compact and light.

 

Cylinder head (Serial)This compact cylinder with a 58mm bore features a cutting-edge power valve unit with a sophisticated mechanism for the lateral support exhaust ports. Matched to a twin-component cylinder head, it is KTM’s secret to all-round grunt. The layout of the water jackets in the cylinder and head guarantees efficient heat dissipation when you’re riding at the limit.

Crankshaft (Serial)A reliable piece of engineering that has been skillfully balanced to guarantee minimal vibrations. It allows a decrease of the displacement to 125cc just by replacing cylinder, piston and head. There’s no more need to change the crankshaft. Two-in-one in no time.

Crankcases and engine covers (Serial)Lightweight, die-cast crankcases featuring a high crankshaft and clutch shaft position, located close to the center of gravity, which results in optimal mass centralization and outstanding rideability. In addition, the engine body is extremely lightweight and compact, while still able to house an E-starter. And because looks matter, the engine covers feature an advanced surface structure in order to reduce the wear caused by the rider´s boots.

Transmission (Serial)A wide-ratio 6-speed Enduro transmission was designed specifically for the small 2-stroke Enduro engine, its gear ratios perfectly in sync with the 150’s power band. The latest production technologies allowed for compact dimensions and minimal weight. Keeping safety in mind, an advanced ´No Dirt´ gear shift lever design prevents muck from blocking the joint. Because even dirt lovers hate mud when it’s in the wrong places.
