New Honda CRF450 models headline CRF family changes
Honda’s enduringly popular CRF range of off-road machines have undergone a major overhaul for 2027.
There is also a new name in the line-up, as the CRF450R and CRF450RX are joined by the new headliner, the CRF450 HRC-WE; the CRF250R and CRF250RX receive minor visual changes to keep them in line with their bigger siblings.
The 27YM CRF450R is effectively a brand-new machine that follows a simple recipe for success: more power, less weight. Building on the strengths of the previous model the CRF450R sports a brand new, much more powerful engine housed in a redesigned, lighter chassis with a completely revised suspension philosophy.

The headline figures standout: 10% more power, and 4% more torque. The result is a machine that accelerates harder, responds faster, and is noticeably lighter and more agile on track.
The performance gain starts with a more efficient, harder-revving engine. The redesigned, more compact unit features a larger bore, a new piston with revised crown, and an all-new crankshaft that enables a shorter stroke and higher compression ratio. Larger titanium intake valves join newly introduced titanium exhaust valves, while a reworked UNICAM valve train improves gas flow efficiency, helping the engine breathe better and deliver stronger, more usable power.
Drive out of corners is improved through a more compact transmission with revised gear ratios, increasing rear wheel thrust across a wider speed range to allow riders to apply power earlier and with greater confidence. The clutch introduces a world-first rubber damper-activated Back Torque Limiter (BTL), bringing refined slipper performance validated by HRC in MXGP, while a redesigned starter motor saves both weight and space.
Control is just as important as outright performance, and the electronics package reflects that. HRC Launch Control and Honda Selectable Torque Control (HSTC) are now updated with settings taken directly from factory race machines, offering sharper, more adaptable performance in changing conditions. The Engine Mode Select Button (EMSB) continues to give riders instant control over engine character, tailoring delivery to suit both rider preference and track demands.
Handling has been sharpened, stability increased, and predictability across even the roughest of track conditions improved by a 70% new frame. New sections, optimized materials and manufacturing processes have increased overall rigidity without increasing weight over the 26YM. This new frame works in harmony with a new, lighter aluminium swingarm that has been shape-optimised not only for performance but also to improve access for air filter maintenance.
The 27YM CRF450R gains all-new dynamic bodywork with redesigned shrouds and side covers to allow a flat knee trajectory, front to back of the machine, to be maintained. The side covers are now symmetrical, and smaller in radius at the rear with deeper cutouts to improve rider gripping power when the rear is fully loaded under acceleration. For 27YM, the enduro-focused CRF450RX shares the redesigned bodywork – and for the first time ever – the slimline titanium fuel tank of its MX sibling.
Topping the line-up is the limited edition 27YM CRF450R HRC-WE, which adds Works Edition factory exotica to the standard machine. Hand finished inlet and exhaust ports, plus a new Yoshimura Titanium downpipe/muffler and Twinair filter boost peak power, while exclusive suspension components and cosmetic detailing create a truly special, high-end race bike.
The smaller capacity CRF250R and CRF250RX are updated for the new model year, receiving the same revised graphic package as the 450cc duo for a unified family look and feel, whilst the CRF250RWE is renamed as the CRF250R HRC-WE in keeping with its bigger sibling.
All 27YM CRF models use Extreme Red as their base colour, and feature all-new HRC inspired graphics built around increased application of blue, and an oversized Honda logo that brings consistency across all of Honda’s racing activities – on and off road.
