• 2012 KTM 450 SMR

"Ready to race" in its purest form, the KTM 450 SMR provides perfect technology for the racetrack, one that riders will come to enjoy for all of its awesome benefits.

For the 2012 model, the 450 SMR is equipped with the very finest components that money can buy, including a new chassis with high-quality WP suspension components and high-tech brakes and a renowned powerhouse of the 450 SX-F engine that has turned the 450 SMR into an invincible weapon in every Supermoto race.

We shouldn’t expect anything less, either considering the bike has been built with a huge amount of innovative technology, clearly setting the standard in production Supermotos. Headlining the bike’s list of impressive features is a 450cc DOHC engine that comes mated to a 5-speed transmission that has been specially designed for Supermoto and an APTC anti-hopping clutch. This provides everything you need as standard for landing on the very top of the podium.

The APTC anti-hopping clutch on the 450 SMR 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.

Lastly, you’re going to get a real good treat with the KTM 450 Supermoto R and the fact that it has been integrated with an extremely lightweight titanium exhaust header and the innovative "Header Pipe Resonator System“ (HPRS), in conjunction with the new silencer, guaranteeing even greater performance at further reduced noise levels.

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.

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.

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.

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.

Frame and Suspension

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.

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.

"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.

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.

totalmotorcycle----"Following the “Ready to Race” slogan, the long – awaited “new generation“ of the legendary 450 SMR is finally available – a brand new development equipped only with the finest technology. The barking DOHC 1-cylinder engine has been taken fairly straight from the powerful 450 SX-F Motocross. The compact single’s core is a high tech, DOHC cylinder head with titanium valves and DLC coated followers."

Motorcycle-USA----"The KTM 450 SMR model is ready to race and win. It has a 450cc engine that is combined with a compact starter which means lighter weight and a five speed transmission that was made for the supermoto with an APTC anti-hopping clutch. Just for good measure to make sure that you get going, they have implemented a backup kick starter. Give it a try; you might just be surprised with the 245 pound beast."

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio

I can’t imagine riding a 450cc dirt bike. I know these bikes are more lighter than those superbikes. So it would surely amaze you of its speed.
