The advanced twin-spar aluminum frame of the CRF450R also contributed to its stability and maneuverability, making it an ideal choice for motocross racing.
The suspension system on the 2017 Honda CRF450R was another noteworthy upgrade. The Showa forks and shocks on the bike were refined, with improved damping and spring rates that made the ride much smoother and more responsive. The brakes on the CRF450R were also upgraded, with a larger front disc rotor and a new caliper design that improved stopping power.
Finally, the 2017 CRF450R came equipped with a range of advanced electronics, including traction control and launch control. These features allowed riders to have greater control over the bike's power and performance, making it easier to navigate challenging terrains.
Overall, the 2017 Honda Powersports CRF450R was one of the most impressive dirt bikes on the market.

With a Dunlop D404 street tire mounted on its rear wheel, Honda's 450cc motocross bike spun the drum on our in-house Dynojet 250i rear-wheel dynamometer. Although it fell to fifth in peak horsepower with 52.5 hp at 9,100 rpm, the CRF450R shot back up to first in maximum torque with 35.1 lb. -ft.
However, the CRF450R is not far behind with 53.8 hp at 9,300 rpm.
As on the CRF450R, the EMSB (Engine Mode Select Button) provides the rider with 3 distinct choices: Mode 1 equals all-round smooth performance, Mode 2 gives the most easy-to-manage throttle feel, and Mode 3 delivers the power in the most aggressive, responsive way.
The key is frequent oil changes and a clean air filter. A well maintained 450 ridden by a fast motocross guy will easily go 60 hours on a topend (piston,rings, timing chain).
