Fast50s - Honda CRF150F - CRF230F

The Honda CRF150F is an off road motorcycle that was introduced in 2003 as the successor to the Honda XR series. The 150F is a mid-range dirt bike for beginner to intermediate riders, teens or adults. It is mainly used for family recreation on/off road trails. The stock model has a stiff suspension, narrow seat and high ground clearance. The 2003 CRF150F was styled after Honda's racing bikes, with tuned suspension and 156 cc (9.5 cu in) engine. It had a 5 speed manual transmission and O ring chain drive, and the Pirelli MT18 tires. The front brake was a 240mm hydraulic disc brake. Redesign came in 2006. The biggest change for 2006 was to the engine. In other years, the 150F's engine was a smaller version of the 230F. Less power with almost the same or slightly more weight. In 2006, Honda totally reconfigured the engine with a different compression ratio, 9.5:1, and a bore and stroke of 57.3 × 57.8. The overall weight savings of the new 149 cc (9.1 cu in) were significant with an increase in power as well. Another change was a new electric start system. The battery is concealed under the left side panel out of the way from water or mud. With the new light weight engine, the 2006 150F with extra electric start system now weighs about the same as the 2005 model.
