Honda CRF250

The Honda CRF250 off-road motorcycle series appeared in September 2003 (model year 2004), introducing two models to the market - Honda CRF250R (cross) and Honda CRF250X (enduro) ... These models positioned themselves as replacements for the outdated XR line, as well as the 2-stroke crossover model Honda CR250R.

The Honda CRF250R and Honda CRF250X models were targeted at the markets of Europe, North America, Australia and Japan (the CRF250X has been available there since the end of 2010).

The Honda CRF250 series is based on a 1-cylinder 4-stroke liquid-cooled engine, with a volume of about 250 cm³, with one camshaft and 4 valves. The engine modification for the crossover version of the Honda CRF250R featured more boost, exhaust system and constant change every few years. The engine for the Honda CRF250X was largely unchanged from 2004 to 2017.

Both models featured an aluminum frame, sport adjustable suspension (47mm inverted fork + Pro-Link swingarm with fully adjustable shock absorber), disc brakes and a 5-speed gearbox.

The first major facelift was the Honda CRF250R in 2009. The motorcycle received a new version of the engine with an increased compression ratio and an injection power system. The engine has also been bolstered with stiffer valve springs and stronger aluminum piston material. The frame has become thinner and lighter, the wheelbase and swingarm length have been increased, and the diameter of the fork stays has been increased to 48 mm.

In 2010, as mentioned above, the Honda CRF250X model became officially available in the Japanese market. Unlike the motocross version, the CRF250X did not undergo major changes and was still equipped with a carburetor power system.

In 2012, a new budget model appears Honda CRF250L, which, although it has a similar name, does not belong to the full CRF line.

By August 2013, Honda introduced an updated version of the Honda CRF250R crossover model. The motorcycle received a new generation of frame and swingarm. To improve weight distribution, the exhaust has become double. The suspensions remain the same, but have changed their characteristics for the new frame and swingarm. New generation of the engine - increased compression ratio, redesigned piston and combustion chamber, new 2-stage fuel injection system 2 PGM-FI.

For 2017, the Honda CRF250R gets another major update. The new engine - increased the compression ratio, got a new cylinder head with two camshafts (DOHC), new titanium valves, a new intake design, an electric starter instead of a kick. New frame. Electronic Systems: 3-Stage Launch Control (HRC Launch Control), Engine Mode Select Button (EMSB). The new front suspension is an inverted fork with 49mm stays.

For 2018, the Honda CRF250R model is slightly modified with new camshafts and an updated look. For 2019, the Honda CRF250X model changes its name to Honda CRF250RX , gets a new look, a new engine from the CRF250R, differing in ignition settings, suspension settings and an increased fuel tank capacity.
