2014 KTM 150 SX

Posted on by  

The 2014 version of the KTM 150 SX is here. To keep it up with its rivals, the motorcycle has received a series of important modifications so we can expect to a boost of performances.

The most important upgrade is represented by the new engine which is now stronger thanks to the newly-developed intake reed valve with Boyesen high-performance reeds. It also features an optimized piston grinding shape and a new carburetor setting. Its power continues to be kept in check by the same old, six speed gearbox with multidisc clutch.

The engine is mounted on a modern frame made of lightweight, high-strength chromoly steel sections that offers a perfect compromise between longitudinal stiffness and torsional rigidity.

Together with the improved engine, the 2014 KTM 150 SX has also received a new, lightweight polythene tank with a capacity of 1.98 gallons.

Hit the jump for more information on the 2014 KTM 150 SX.

Overview

KTM 150 SX

The best of both worlds.

With a stronger engine, the 2014 150 SX keeps even closer on the heels of the 250cc 4-strokes, not the least thanks to its unbeatably low weight.

Wheels:

The wheels use lighweight, CNC-machined hubs, high-end Excel rims and spokes coated in black with lightweight aluminum nipples to achieve maximum stability at minimum weight. The OEM Dunlop Geomax MX51 tires deliver perfect traction and outstanding performance.

Brakes:

High-Tech Brembo brakes have always been standard equipment on KTM offroad bikes. Combined with the lightweight Wave discs, they are the ultimate solution in braking technology. The SX models gain a newly-developed master cylinder with a new reservoir, a smaller piston diameter and optimized lever kinematics. Combined with optimized brake pads, this makes for another perceptible improvement of front brake performance and action.

Engine:

A newly-developed intake reed valve with Boyesen high-performance reeds along with an optimized piston grinding shape and a new carburetor setting allows for improved response, optimized performance and increased durability.

Graphics:

New classy graphics with clear lines visually underscore the exacting standards of what KTM deems a true, cutting-edge motocross bike.

Handlebar:

All SX models are fitted with the super strong, tapered Renthal Fatbar 827 whose bend is especially well suited for the requirements of motocross. The proven standard KTM mount allows to fix the handlebar in four different positions. A large Renthal crash pad in a classy combination of black and silver, offers effective crash protection for the rider.

Bodywork:

In shaping the bodywork, the KTM designers’ ergonomic and design focus was to achieve complete harmony between rider and bike, down to the finest details. The front fender is a prime example of a moulded polymer component gaining maximum stability through a well thought-out structure and mounting.

Seat:

Ergonomically perfect, the seat has received an improved foam core, ensuring greater comfort and durability.

Air box:

The airbox design offers maximum protection of the air filter against soiling while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM.

Fuel tank:

All models of the SX range have a new, lightweight polythene tank with a capacity of 1.98 gallons. The new filler cap with the inside thread makes for an easier and reliable closure.

Frame:

The state-of-the-art frame design made of lightweight, high-strength chromoly steel sections combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability.

Suspension/damping:

KTM 150 SX

The rear monoshock as well as the 48mm upside-down front fork by WP Suspension guarantee the best response and damping characteristics. In 2014, the fork has more reserves against bottoming out thanks to their optimized setting. Of course, compression and rebound damping can be adjusted to the track conditions and the rider’s preferences with a twist of the wrist - the rear monoshock even has separate high and low speed adjustments.

Swingarm:

KTM 150 SX

Designed using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm have been optimized for minimum weight at optimum stiffness and precisely defined flexibility provides perfect stability at minimum weight. For 2014, the engineers have revised the chain guide to increase reliability while lowering the weight.

Triple clamps:

KTM 150 SX

Top-quality, CNC-machined triple clamps have been something of a KTM trademark. Ensuring a precise handling, they perceptibly support the flex characteristics, and with it, the fork’s action.
