Honda CRF150F

The Honda CRF150 was introduced in 2003. The bike was a bigger version of the XR100 and was targeted at adults and bigger kids. The 150F was a huge hit with the off road crowd. Its torquey, slow revving, 4-stroke engine is perfect for ridding through the woods, rocks, and nasty stuff. The backyard MX racers took to the bike, too, with the majority of the 150 4-stroke classes around the country being won by the 150F. The 150F is super tough and reliable. This has to be one of the most maintenance free Dirt bikes ever built. The bike is super heavy but that is the price you pay to have it NEVER break. This bike can take a licking! Over the years the 150 has been updated twice. The first change came in 2006 with a completely new engine. The new engine even with electric start weighed the same as the old one. It also received roller rockers that let it rev much higher. In 2008 the 150F received new body work with a skinnier seat and tank. BBR has spent many years on the 150F riding poker runs and racing around the country on our perimeter framed versions. The must have items are the rev box, exhaust system, heavy duty springs, shifter and handle bars. BBR has many more items for the 150F so let us know how we can help.
