2013 Honda CRF250R

COMPETITIVE SPIRIT: The 2013 CRF250R's received a large amount of improvements for its racing performance.

CAPE TOWN - The Honda CRF250R won both U.S. Supercross Lites titles in 2012 and knowledge acquired in both campaigns has been fed into development of the 2013 model.

Large improvement in racing performance is often the sum of many small, marginal gains and nowhere is this more true than the highly-competitive 250cc MX arena, where even the smallest change can have the biggest effect.

Honda has evolved its CRF250R for 2013 focusing their efforts on the engine and suspension.

MODEL OVERVIEW

The engine’s response at low and mid-rpm has been boosted thanks to recalibration of the fuel injection, while the rear shock has been revised with new internals and damping rates. The front fork has a new, stiffer spring with damping to match. Taking advantage of the suspension’s upgraded performance are new Dunlop tyres, offering improved traction. The rear also saves weight.

ENGINE

The bike’s 249cm³, liquid-cooled four-valve Unicam engine has, Honda claims, always impressed riders of all abilities with its broad spread of useable power, everywhere in the rev-range, plus a pin-sharp and instant throttle response.

CHASSIS

Its steering geometry, aluminium twin-beam frame and swingarm are unchanged, but the Showa 48mm inverted cartridge forks feature new springs with a stiffer (from 4.4 to 4.6 Kg/cm) rate, for more precise handling through extra-rough sections of track. The forks’ internal sub-piston diameter has increased from 35mm to 37mm, for improved low speed damping. Both rebound and compression damping can be adjusted through 16 positions.

A redesigned internal damper adjuster bolt (up 2mm in diameter to 11.5mm), guide and coil spring improves the Showa rear shock’s high-speed control and bump absorption. Damping rates are firmer to suit. The Pro-Link rear suspension has 12.3in travel, plus spring preload adjustment and 17-position rebound adjustment. Compression damping is separated into 13-position (low-speed) and 3.5 turns (high speed).
