Two-stroke golden era
If there was a golden age for the CR250R, it was the late '80s through well into the '90s. The bike underwent significant design and performance improvements during this period. A major overhaul in 1987 introduced a new chassis and engine, while the inverted front fork technology was added in 1990. Piloted by iconic racers like Ricky Johnson, Jeff Stanton, and Jeremy McGrath, the 250R won numerous AMA Pro Supercross and Motocross championships, cementing the bike's legacy in motocross history.
In the late 1990s, the CR250R underwent improvements in engine performance and handling, including the introduction of an all-new aluminum frame in 1997. The bikes of this era were known for their aggressive power delivery and sharp handling, which demanded skill from their riders. By 2001, the 250R had achieved a high level of innovation. Although it was still manufactured until 2007, 2002 saw a significant shift in the motocross world toward larger-displacement 450cc four-stroke engines.
The genesis
As the successor to the revered CR250R, the all-new CRF450R marked a significant shift in Honda's motocross strategy towards four-stroke engines. This transition was driven by changing regulations and the motocross community's growing preference for the torque and power delivery characteristics of four-strokes.
The original 450R set new standards for power, agility, and reliability and was the first model to feature Honda's revolutionary Unicam® engine design. Still used throughout the Honda Powersports lineup today, the compact, single-overhead-camshaft design is lightweight and efficient, delivering an unmatched power-to-weight ratio.
Over the next decade, the CRF450R underwent continuous refinement. Honda focused on incremental improvements to enhance performance, reduce weight, and increase reliability. In 2008, the bike received the HPSD, Honda's Progressive Steering Damper, which significantly improved handling and overall stability, especially at high speeds.
However, the most notable change came in 2009 with the introduction of a completely redesigned 450R. This model featured a new, more compact engine, a revised chassis, and electronic fuel injection (EFI)—a first for Honda in the 450 motocross category. EFI improved throttle response and ensured consistent performance across a wide range of conditions, marking a significant step forward in moto technology.
