Motorcycle specifications KTM450 EXC 2016 Muscular enduro

The 450 and 500 EXC models are unquestionably the most powerful enduro machines in their class. Combining low weight and high displacement, their advanced SOHC (single overhead camshaft) 4-stroke technology is the best choice for riders looking for the optimum performance of four-stroke and the maneuverability of the E2 and E3 categories. These bombs are undeniably the benchmarks in their respective categories.

frame

the modern frame design of the 450 EXC, featuring tubular sections in lightweight, high-strength chrome-molybdenum steel, combines maximum longitudinal rigidity with optimum torsional rigidity. It ensures excellent handling and steering precision, as well as excellent riding stability. So the new frame doesn't just come in a new color; it also sets the benchmark in terms of weight and stability. The frame is the same orange color as that of the KTM factory team, making it even more attractive. Thanks to the combination of frame design and the PDS rear damping system, shocks to the rear wheel are optimally absorbed and dissipated. The 2016 model is also equipped with a sturdy frame protector.

suspension / damping

the KTM 450 EXC gets a new fork with new bellows, reduced caster and new suspension settings optimally matched to weight and engine. It also features new fork protectors. WP suspension components have been designed specifically for enduro riding. They guarantee optimum traction and comfort. at the rear, a PDS shock absorber from WP Suspension is connected directly to the upper part of the swingarm. KTM machines come with a wide range of rebound and compression adjustment options for high and low speeds as standard.

swingarm

the design of the cast-aluminum swingarm was the result of careful calculations and computer simulation. Its design and wall thickness guarantee optimum rigidity while reducing weight, as well as precisely defined flexibility.

fork tees

top-of-the-range CNC-machined fork crowns are designed specifically for enduro riding, ensuring precise handling by influencing fork flex. Feedback to the front wheel is exceptional, even on the roughest terrain, increasing safety and passing speeds.

brakes

kTM off-road models have always been equipped with high-tech Brembo brakes and Wave discs, the ultimate braking solution. True benchmarks in the enduro category, they remain unchanged on 2016 models.

wheels

giant's black 7050 T6 aluminum rims with black spokes are matched by CNC-machined hubs and lightweight aluminum spoke nipples, guaranteeing optimum stability for minimum weight. Specially developed for KTM, Maxxis enduro tires ensure optimum traction and exceptional performance.

front wheel axle

the front wheel axle has been reduced from 26 mm to 22 mm to reduce weight and improve front-end feel. Adjusted caster and greater ground clearance provide enhanced stability.

fork guards

the fork protectors have been adapted to the fork legs and are also lighter. The open design offers the same level of protection while allowing easy access to the fork legs for cleaning and maintenance.

engine

developed for committed enduro riding, the 449.3 cc SOHC engine is extremely compact, easy to maintain and offers exemplary longevity at minimal weight. Combined with Keihin's EFI system, it offers performance and comfort particularly suited to enduro riding.

cylinder head

the cylinder head features a single overhead camshaft. This drives two titanium intake valves and two steel exhaust valves. The weight-optimized valve train reduces friction and improves performance, while reducing the effect of engine braking.

piston

the lightweight forged bridged box piston features the same rings as those on the 450 SX-F.

balancer shaft

to compensate for inertia forces, the engine is fitted with a balancer shaft that also drives the water pump.

crankshaft

the crankshaft, with its 63.4 mm stroke and ultra-light connecting rods, is manufactured by Pankl from special high-strength steel. The crankshaft is fitted with a smooth connecting-rod bearing. Two bearing shells are force-fitted directly onto the crankpin. The bearing is supplied with oil from the engine's pressure lubrication system. This design extends engine life and crankshaft service intervals, saving the customer time, effort and money.

dDS clutch

the DDS (damped diaphragm steel) one-piece clutch housing is machined from a single piece of high-strength steel, together with the primary transmission pinion. This process guarantees unrivalled reliability, and contributes to the engine's compactness thanks to its rivet-free design and ultra-thin steel linings. The elastic diaphragm allows the use of an additional rubber damping system inside the clutch hub, ensuring transmission reliability and excellent driveability. Finally, the Brembo hydraulic clutch mechanism associated with this elastic membrane plays an essential role in the clutch's progressiveness and operation.

starter

the 450 EXC is equipped with a kick starter as standard, as well as an electric starter. The electric starter is well protected at the rear of the cylinder.

gearbox

the 6-speed gearbox features smooth, precise shifting.

engine Management System

keihin's Engine Management System, combined with electronic fuel injection and a 42 mm throttle body, ensures immediate response and optimum engine performance. The 196 W oil-cooled AC alternator is sufficient to power fuel injection, lighting and all other electrical consumers. Combined with the engine map selection control offered as an option in the Power Parts range, the EMS allows the driver to select different engine characteristics. What's more, the optional User Tuning Tool allows engine data to be read using a laptop computer, and ignition and injector mappings to be modified with just a few clicks.

fairing

the fairing design is ergonomic and functional, so that the machine is in perfect harmony with its rider, down to the smallest detail.

handlebars

all EXC models are equipped with ultra-high-strength, profiled Neken handlebars made of high-tensile aluminum alloy. Bridges of proven design standards allow the handlebars to be fixed in four different positions. Leonelli's new lighting control is adapted to the demands of enduro riding. Standard perforated handguards provide optimum protection for the rider's hands.

speedometer

mAE's speedometer integrates all indicators and warning lights into a single unit, with the exception of the turn signals. This gives the instrument panel a clean, minimalist look, with excellent visibility of all available information.

fuel tank

all fuel tanks are made of lightweight polyethylene. These large-capacity tanks are designed specifically for enduro riding, and all feature a quarter-turn bayonet-type filler cap opening mechanism for fast, easy opening.

air box

at the same time, the ingenious design of the air box provides optimum protection for the air filter against any damage.on of the air filter against dust penetration and ensures maximum airflow for high performance. The airbox covers are manufactured using the bi-component process with new molded graphics. The filter can be replaced quickly, without tools. In addition, two additional lugs on the cover allow it to be secured with screws if required.

graphics

the new graphics on the 2016 models stylishly complete the look of the enduro machine range.
