2007 Honda CRF 150 R

As a successor to the Honda CR series. The full sized motocross bikes are equipped with liquid-cooled, single cylinder four-stroke engines that are available from 149 cc (9.1 cu in) to 449 cc (27.4 cu in).

To 2009. As of 2026, the CRF-F series includes the CRF50F, CRF110F, CRF125F, CRF125FB (Big wheel), CRF250, CRF300F.

. Further down the line, the CRF450X and CRF250X bikes emerged, both designed for mostly off-road use.

The CRF230L was introduced as an entry-level dual sport and was street legal from the factory, but still retained a dirt-oriented design. All have full lighting and electric starters.

. In April 2012, the completely redesigned dual-purpose CRF250L was launched in Japan.

The CRF 110F, CRF125F, and CRF250F all come standard with electronic fuel injection. This improves cold weather starting and makes the bike easier to maintain because of the lack of a carburetor to clean.

The CRF 250F was replaced by the CRF 300F. Source: As of 2026, the CRF-RX series includes the CRF250RX and CRF450RX.
