I can sum up my experience with the White Brothers-modified CRF307X little red thumper in one word, that word is: fun. The 307 had just about every bolt-on imaginable, making the bike a real treat for the eyes but pretty punishing to the pocketbook. Two of the big-ticket items-the Tom Morgan engine and the Race Tech suspension-were what put the dream in this ride. Roaring up the bike was just a push of a button away, thanks to the electric start. Upon firing, the White Brothers pipe gave the bike a good hearty tone that stayed under the 96-decibel sound limit. It took only a brief ride to notice that the motor makes some serious power. The combination of the heavy X flywheel and the quiet pipe insert keeps the engine from having a radical hit. Instead, it pulls smoothly from idle, but at a little above idle, it starts to build oomph. There is plenty of boost to pull you through the tight stuff. The delivery remains buttery smooth and pulls consistently through the rpm range. In fact, the motor is so smooth, you could almost be fooled into thinking it’s slow, but it’s not. The consistent pull of the motor is perfect for long rides since it doesn’t tire you out. The motor and transmission are a match made in heaven, as the bike shifts perfectly every time and easily pulls the spacing between ratios.The smooth motor is only part of what makes this bike so much fun to ride. The CRF handled great, and thanks to the Race Tech suspension, it’s one of the most nimble-feeling off-road bikes ever. No matter what the conditions were, the bike cornered awesomely. The front end stuck in every corner. Even on the slippery hardpack, the bike would cut an arc wherever you wanted it to. The suspension was nearly perfect for me: plush enough to soak up the small chop while still maintaining some stiffness to take care of the big hits. Only in the roughest of sections would the rear end kick a little, but that was probably due to my light weight. I did notice that the more aggressively I rode, the better the suspension seemed to work.The CRF307X is one great, easy-to-ride package that was super fun.
