2014 Honda CRF 250 R


The 2013 Honda CRF 250 R was a neat evolution of the previous model, the very one that won the two US Supercross Lites titles in 2012. For 2014, development engineers have chosen the path of revolution rather than l ‘evolution: they optimized the CRF 250 R by adopting the same philosophy and the same framework as that of the CRF 450 R. The PGM-FI engine and fuel injection also received improvements to increase horsepower, torque and throttle control while weight was limited wherever possible..

At the center of the transformations of the CRF 250 R 2014, we find the latest generation of aluminum frame inaugurated on the 2013 vintage of the CRF 450 R. The lowering of the center of gravity and the reduction of inertia provided by this new frame increase tenfold. again the dynamic behavior of the CRF 250 R on the runway but also in “aerial” sequences. Internal modifications to the Showa 48mm inverted fork are complemented by the adoption of a new compact rear shock as well as upgrades to the Pro-Link and aluminum swingarm design..

Always as exemplary in terms of availability and ease of operation, the 249 cm3 single-cylinder has benefited from a multitude of developments on the part of HRC engineers, in particular on the PGM-FI injection feed and on the flow of gas streams at the intake, cylinder head and exhaust.

In the end, the new CRF 250 R comes even closer to perfection: once again, the HRC has given birth to a perfectly homogeneous and efficient machine. A superb tool for professionals as well as hobbyists.


For this 6th generation of aluminum frame dedicated to the MX, the chassis specialists of the HRC have accumulated the requirements: improved traction at the front as well as at the rear, feeling of reinforced grip, stability and braking at high speed, feeling of lightness in turns whatever the conditions. At just 9.35 kg (for a total weight of 105.7 kg), the frame of the CRF 250 R emerges as the new benchmark in its class.

In fact, this is a total redefinition: the junction point of the steering column and the main spars is indeed much lower on the column tube, now closer to the midpoint than to the top. This change helps lower the center of gravity and introduces a kind of “calculated flexibility” into the frame for the benefit of better front grip and better cornering speed. A cradle specific to the CRF 250 R supports the engine.

The steering geometry (27’23 ° angle, 116.7 mm drag and 1489 mm wheelbase) takes advantage of the new frame characteristics to offer a more direct connection to the front tire with, in the end, a better feeling of the grip available and therefore faster cornering speeds. With a lower center of gravity, side-to-side swings are easier, promoting a feeling of confidence in the pilot and limiting fatigue..

Careful arrangement of the equipment around the frame contributes to the centralization of the masses, to a significant reduction in inertia and to the feeling of lightness which emanates from the machine. Lightened to the maximum, the electrical components – electronic control unit, capacitor, regulator and electrical harness – are concentrated around the injector body. Lighter and cleaner than the CRF 250 R, the new radiators are now located lower.

In terms of suspensions, the upper mounting of the Showa shock absorber is placed 14.5 mm lower on the frame while the shock absorber itself – which receives new spring, compression and rebound settings – is also 14.5 mm shorter. The benefit of mass centralization in this area results in a reduction in inertia in the axis of the machine: thus it is possible to brake harder without compromising stability. Thanks to a greater height in the center and in the front, the new aluminum swingarm offers more rigidity, deforms less and improves the propulsion of the rear tire out of a corner..

In 2013, the Showa 48mm inverted fork received new, larger diameter internal pistons (35-37mm) for better low-speed damping characteristics. For 2014, the spring setting has been adapted to the new characteristics of the frame. Rebound and compression still offer 16 adjustment possibilities.

The Pro-Link rear suspension benefits from new gear ratios that allow it to debate over 375 mm. Fully adjustable, the shock absorber offers 17 possibilities of rebound adjustment while the compression is adjustable in 13 positions (low speeds) and 3.5 turns (high speeds).

The new trim of the CRF 250 R marks an evolution of the “triangular” style seen on the 2013 CRF 450 R: the machine is literally built around the rider, with particular attention paid to ergonomics and mass centralization. The radiator scoops, the side covers, the ultralight saddle or the fuel tank (6.3 liters) have a continuity of shape which gives the rider significant freedom of movement and fluidity in his movements..

At the same time, the fixing points of the covering with which the pilot is likely to be in contact are very rigid so as to allow the latter to “grip” the motorcycle for a better feeling and better control. Finally, the rear fender has an integrated lifting point which facilitates the handling of the machine in the pits..

On the tire side, the 80 / 100-21 casings for the front and 100 / 90-19 for the rear help reduce unsprung weight. With regard to braking, the front disc “petal” of ø 240 mm and its 2-piston caliper are protected by a 2-part cover while the rear disc and single-piston caliper are also protected from projections.


During the development cycle, the HRC engine manufacturers focused their attention on a number of points aimed at increasing the power and availability of the CRF 250 R engine. The water-cooled 249 cc Unicam 4-valve single cylinder has always impressed its users not only by the amount of power available at any speed but also by its liveliness at the slightest opening of the throttle. Improving this ubiquity was one of the objectives to be achieved.

Thanks to a compression ratio reduced from 13.2 to 1 to 13.5 to 1 as well as a redesigned cylinder head and intake and exhaust ducts, combustion efficiency has been increased. The bore and stroke values ​​remain unchanged (76.8 x 53.8 mm), as does the valve diameter (ø 30.5mm titanium for intake, ø 25 mm steel for the exhaust). On the other hand, the gearbox has been revised in order to increase its resistance. In the end, the progress in terms of power and torque was concentrated on the most important rev range, namely low and medium revs..

As on the CRF450R, the new PGM-FI injection mapping and the modified injector angle further add to the performance gain. Finally, copying that of the 450, the air box is associated with a double exhaust specific to the CRF 250 R and again favoring mass centralization..
