Show original supplier description
The BBR Motorsports CRF150F 175cc Big Bore Kit with Cam is a comprehensive performance upgrade designed to significantly enhance the power of your 2003-2005 Honda CRF150F. This kit allows for a simple bore-in-bore installation, increasing the engine's displacement to 175cc. It comes complete with a 67mm piston, pin, clips, rings, BBR MX camshaft, valve springs, and all necessary head and base gaskets. The included high-performance camshaft features higher lift and duration compared to the stock unit, contributing to a more aggressive power delivery. This translates to a noticeable increase in horsepower, with claims of up to 3.5 HP added. The kit maintains the bike's ability to start easily and idle smoothly, ensuring usability alongside the performance gains. Installation of this big bore kit requires professional machining of your stock cylinder. It is crucial to note that this kit is exclusively compatible with the 2003-2005 CRF150F models. The 2006-2017 CRF150F utilizes a completely different engine and cannot accept this bore kit; for those models, BBR offers a different 195 bore kit.
