2012 KTM 450 SMR

Posted on by

The KTM 450 SMR offers first class performances and is packed with many modern technologies which help it remain among the top dogs in its segment. Moreover, the motorcycle has received a series of upgrades for 2012, hence it just became better.

At the heart of the motorcycle lies a new single-cylinder, 4-stroke, spark-ignition engine. The unit is liquid-cooled and has a 449.3 cc displacement. The engine is brought to life with a compact electric starter and is paired with a 5-speed transmission.

The 2012 KTM 459 SMR rides on new, front 48mm upside-down forks from WP, featuring closed-cartridge technology. On the other hand, the rear wheel is kept in check by a WP monoshock which has been specially tuned for Supermoto racing. Needless to say, that a wide setup range for rebound and compression damping allows individual adjustment of the chassis for the most diverse tracks.

Hit the jump for more information on the 2012 KTM 450 SMR.

OVERVIEW

KTM 450 SMR

"Ready to race" in its purest form, the 450 SMR provides perfect technology for the racetrack. The SMR has been completely redesigned for the 2012 model year. It is equipped with the very finest components that money can buy: A new chassis with high-quality WP suspension components and high-tech brakes plus the renowned powerhouse of the 450 SX-F engine turn the 450 SMR into an invincible weapon in every Supermoto race.

ENGINE

KTM 450 SMR

With a huge amount of innovative technology, KTM is clearly setting the standard in production Supermotos. The mighty DOHC 450 cc engine, which is brought to life with a compact electric starter, is equipped with a 5-speed transmission specially designed for Supermoto and an APTC anti-hopping clutch, providing everything you need as standard for landing on the very top of the podium.

CYLINDER HEAD

The 4 ultra-lightweight titanium valves are actuated by two overhead camshafts, in combination with DLC-coated rocker arms. This means an extremely wide rpm range, optimum engine-speed strength and plenty of power from the very bottom up.

ELECTRIC STARTER

Why use a kick-starter, when the bike can also be reliably started with the push of a button? A huge advantage when things get tough during the race. The small electric starter motor is located in the free space behind the cylinder head, and the battery takes up practically no space in the airbox.

TRANSMISSION

Specially designed for the demands of Supermoto racing, the transmission is equipped with five gears. The rider therefore always has the right gear at hand for every speed range.

CLUTCH

The APTC anti-hopping clutch precisely prevents the rear wheel from chattering, therefore improving control when drifting into curves. This design also significantly reduces the hand strength required to operate the hydraulic clutch. The Magura hydraulic system is completely maintenance-free and guarantees precise application with the minimum of effort.

BRAKES

"Ready to Race" brake technology also makes the SMR unbeatable ahead of every curve: At the front, a radially bolted, four-piston fixed caliper from Magura takes a powerful grip on a floating 310 mm disc from Braking. In conjunction with a radial handbrake valve, the brake system guarantees maximum, but nevertheless controllable deceleration.

WP SUSPENSION

Together with the high quality, CNC-machined triple clamps (with adjustable offset), the 48mm upside-down forks from WP, featuring closed-cartridge technology, are in a league of their own. Both the fork and the WP monoshock have been specially tuned for Supermoto racing, guaranteeing sensitive responsiveness and reliable damping. At the front, new SKF seal rings and teflon-coated slide bushes further improve the sliding behaviour. A wide setup range for rebound and compression damping (there’s even high and low speed at the rear) allows individual adjustment of the chassis for the most diverse tracks.

WHEELS

For maximum stability in curves and easy handling, the KTM engineers chose a 3.5 x 16.5" rim on the front wheel and 5.0 x 17" at the rear. The Dunlop slicks fitted as standard are renowned for outstandingly good grip.

EXHAUST

The extremely lightweight titanium exhaust header and the innovative "Header Pipe Resonator System“ (HPRS), in conjunction with the new silencer, guarantee even greater performance at further reduced noise levels.

FRAME

The new, ultra-lightweight chromoly frame with KTM shock absorber linkage has been developed for the extreme demands of the Motocross World Championship. Thanks to its modern design and wide tube profiles in the steering head area, this frame, in conjunction with the high-strength, die-cast aluminium swingarm, supplies an extremely high level of torsional stiffness, hence ensuring excellent tracking stability above all for Supermoto.

WP SUSPENSION

Together with the high quality, CNC-machined triple clamps (with adjustable offset), the 48mm upside-down forks from WP, featuring closed-cartridge technology, are in a league of their own. Both the fork and the WP monoshock have been specially tuned for Supermoto racing, guaranteeing sensitive responsiveness and reliable damping. At the front, new SKF seal rings and teflon-coated slide bushes further improve the sliding behaviour. A wide setup range for rebound and compression damping (there’s even high-speed compression damping at the rear) allows individual adjustment of the chassis for the most diverse tracks.
