Honda CRF450R 2013 — Specifications

What could have driven Honda to completely overhaul its Honda CRF450R for the 2013 model year, when the machine was already a regular on the podium? The answer comes down to one word: the rider. Everything was rethought to match the sensations of the person sitting on the seat, perched 953 mm off the ground. The result is a 111 kg motocross bike that tries to make you forget it puts out 51 horsepower at 8,500 rpm. Honda worked with legends of the caliber of Jeremy McGrath to fine-tune the behavior of this CRF450R, and the HRC program, battle-tested in the Japanese motocross championship, served as a laboratory. This is far from a simple cosmetic update.

The chassis deserves a closer look. Sixth generation of the aluminum twin-spar frame, redesigned from the ground up for a contained weight of 9.35 kg. The stated objective: to centralize mass as low and as close to the center of gravity as possible. In practice, this translates into a reworked front geometry, a 1,492 mm wheelbase that favors straight-line stability without sacrificing cornering agility, and a generous 330 mm ground clearance to swallow ruts without flinching. Jump landings gain in comfort and predictability. On this front, the 2013 Honda CRF450R positions itself against some serious rivals. As a reminder, the specs and pricing of the 2019 Yamaha YZ450F show that the YZ450F costs $9,299, the same price as the Honda CRF450R and the Kawasaki KX450, proof that the segment remains ultra-competitive year after year.

The real technical revolution of this model year is the fork. Honda drops the conventional hydraulic system in favor of a 43 mm air fork. The weight savings reach 800 grams, which is no small matter on such a light machine. But the main benefit lies elsewhere: internal friction decreases, responsiveness improves, and sensitivity to small impacts is noticeably refined. The rear Pro-Link shock with a 40 mm cylinder completes the package. Braking remains conventional with a single hydraulic disc at each wheel, two pistons up front and one at the rear. Adequate for the intended use, even if some competitors offer more aggressive setups.

On the engine side, the 449.70 cc single-cylinder four-stroke retains its bore and stroke dimensions of 96 x 62.1 mm, but everything else evolves. The compression ratio climbs from 12:1 to 12.5:1, the valves gain in diameter, and airflow improves by 3%. The 47.70 Nm of torque now arrives 10% earlier in the rev range, with a peak at 6,500 rpm. The power curve aims to be more linear, more usable during acceleration phases where grip is precarious. The fuel injection has been recalibrated and the five-speed gearbox reinforced to handle the demands. For those looking for a reliable Honda CRF450R over the long haul, that is a reassuring point. The 6.40-liter tank remains modest but consistent with a purely competition use where motos rarely exceed half an hour.

Priced at €8,690, this 2013 Honda CRF450R is clearly aimed at committed motocross riders, whether licensed racers or knowledgeable amateurs who ride every weekend. A beginner will not find it forgiving: the power is blunt, the seat is tall, and the handling demands a minimum level of technique. On the other hand, for an intermediate to advanced rider, it is a solid working platform. The competition of the era, notably the Kawasaki KX450F and the Yamaha YZ450F, offered similar arguments on paper. But Honda plays the card of smooth power delivery and riding comfort here, two qualities that make the difference when arms start pumping up toward the end of a moto. Tim Gajser would prove a few years later, aboard the Honda CRF450R, that this philosophy can lead to a world title.
