Honda CRF250RX 22YM
CRF250RX 2022
For 20YM it followed development of the CRF250R and gained a major low to mid-range power and torque boost, plus frame and swingarm of the 19YM CRF450RX. 22YM sees a major step forward for the CRF250RX, including chassis upgrades inherited from the 21YM CRF450R improving both ability and agility plus a boost in low-rpm torque for the engine.
From only £8,569.00
Introduction
The battle in MX2 is close competition and generates rapid, constant evolution. For 19YM – and after 18YM’s full redesign, with seventh-generation 17YM CRF450R frame and swingarm, new Showa suspension and brand-new DOHC engine – Honda gave their CRF250R much stronger bottom-end torque and HRC launch Control.
And for the same model year, a cross-country option in the form of the new CRF250RX was added to the range, with off-road specific modifications drawn from the CRF450RX including larger fuel tank,18-inch rear wheel plus off-road specific engine mapping and suspension changes to ensure it was equally at home speeding up a root-strewn climb, or slicing precious seconds off an Enduro special test.
For 20YM it followed development of the CRF250R and gained a major low to mid-range power and torque boost, plus frame and swingarm of the 19YM CRF450RX. 22YM sees a major step forward for the CRF250RX, including chassis upgrades inherited from the 21YM CRF450R improving both ability and agility plus a boost in low-rpm torque for the engine.
Model Overview
A full 3kg lighter the CRF250RX’s new frame and swingarm’s rigidity balance – combined with tighter chassis geometry and heightened ground clearance – target peak cornering performance in any riding situation. In support the Showa suspension gets a re-valve, improving bump absorption, traction and control.
Riders have always loved the CRF250R’s top-end power hit. To link up with the healthy mid-range, extensive revision to both intake and exhaust efficiency yields much-improved low-rpm drive; the ECU mapping is also revised optimising air/fuel mixture and ignition timing.
A great deal of work has also gone into enhancing high-rpm cam timing accuracy and long-term reliability. A 9-plate clutch and new ratios for the strengthened gearbox ensure none of the extra punch is wasted. For 22YM the CRF250RX also wears standard-fit knuckle guards.

Overview
The new CRF250RX is the strongest it’s ever been, inheriting the chassis of the 22YM CRF450RX, plus extensive cylinder head development producing a considerable low-rpm torque boost with enhanced reliability. New radiators improve efficiency, the clutch now has 9 plates and lighter lever feel, while the strengthened gearbox features revised ratios for improved ‘roll-on’ performance. The Showa suspension is re-valved for enhanced bump absorption, and knuckle guards are also standard fit.
