Honda CRF150RB BIG WHEEL 2024 Parts & Accessories

First introduced in 2003, the Honda CRF150 Series (CRF150F and CRF150R) represents Honda's dual-track approach to youth and intermediate off-road performance. The air-cooled CRF150F (2003–2017) was engineered as an accessible, ultra-reliable trail bike featuring forgiving power delivery, low maintenance requirements, and user-friendly trail ergonomics. In 2007, Honda introduced the revolutionary CRF150R and CRF150RB (Expert/Big Wheel), a pure race-bred four-stroke competition motocross machine featuring a high-revving 149 cc liquid-cooled Unicam engine designed to directly compete against 85 cc two-stroke race bikes.
