Throw Fun into High Gear There is no one single feature that makes the CRF®230F stand apart. Instead it's the combination of all its features that has made it one of the most popular trail bikes we build. Features like the bulletproof six-speed transmission. The plush Pro-Link® rear suspension with long travel. The durable and right-sized 223 cc four-stroke engine. The rugged frame, lightweight materials front to back, and of course, the electric starter that gets you going with the push of a button. Add our legendary reliability and build quality to the mix, and you end up with a bike that delivers non-stop fun for adults and larger teens alike. So if you like low maintenance and ease-of-operation mixed in with your fun, then the CRF230F is the perfect bike for you.
