At the heart of the overhaul is a completely newly developed single-cylinder engine. Honda focuses on a larger bore, a modified piston, a new crankshaft with a shorter stroke, and higher compression. Additionally, larger titanium intake valves and new titanium exhaust valves are employed. The revised UniCam valve train is designed to improve gas exchange and allow the engine to breathe more freely.

Honda claims that the new CRF450R delivers over 10 percent more power and 4 percent more torque. This enhancement is expected to result in stronger acceleration, more immediate throttle response, and improved handling.

The compactly designed transmission receives new gear ratios. According to Honda, this should enhance propulsion across a wide speed range. Also new is a "Back Torque Limiter," a solution controlled by rubber dampers that aims to provide a refined anti-hopping function. Honda notes that this technology has already been used by the HRC factory team in the Motocross World Championship. A newly developed starter is intended to save both weight and space.

The electronics have also been revamped. According to Honda, the HRC Launch Control and HSTC (Honda Selectable Torque Control) have settings derived from official HRC race machines. This is intended to allow for more precise adaptation to various track conditions. The EMSB (Engine Mode Select Button) on the handlebar enables multi-stage power delivery adjustment.

Another focus is on the chassis. Honda mentions a frame that is 70 percent newly developed. Optimized materials, new manufacturing processes, and design changes aim to increase rigidity without adding weight. The construction is complemented by a lighter aluminum swingarm, which is designed to not only enhance performance but also ease access to the air filter for maintenance.

The fairing, seat, and side panels have been redesigned. According to Honda, the ergonomics are specifically tailored for situations where acceleration out of corners while seated is crucial. The titanium fuel tank has been expanded to a capacity of 7.1 liters.

Alongside the standard model, Honda is once again releasing the limited CRF450R HRC Works Edition. It features hand-finished intake and exhaust ports as well as additional premium components. These include a titanium header and titanium muffler from Yoshimura, as well as a TwinAir air filter. Honda states that these upgrades are intended to boost peak performance. The package is completed with selected suspension components and exclusive design features.

The CRF250R and the variant soon to be known as the CRF250 HRC Works Edition will also receive visual updates for 2027. Both models will feature the same "Extreme Red" graphics as the 450 models. This aims to create a unified brand appearance within the motocross family and in connection with Honda’s racing activities in MotoGP and the Superbike World Championship.

The new 2027 model year Honda off-road lineup is expected to be available in Austria starting in fall 2026. Leading the range are the two 450 motocross bikes, while the CRF250R and the CRF250R HRC Works Edition round out the lineup. Prices including VAT and NoVA are as follows:

• Honda CRF450R: 11,490 Euro
• Honda CRF450R HRC Works Edition: 14,690 Euro
• Honda CRF250R: 10,190 Euro
• Honda CRF250R HRC Works Edition: 12,390 Euro
