2007 Yamaha Wr250f , The '07 250WR comes with the aluminum frame that appeared on the 2006 MX bikes. The frame change was one of the significant mods targeted at giving the WR lineup a smaller, lighter and quicker-steering machine, a primary goal for making the bike more race-worthy out of the box. One of the changes that came with this new alloy chassis is engine oil placement. Where it was once held in the steel front downtube, the 250F uses an oil reservoir that sits against the front of the cases between the wishbone spars. Moving the lubricant from the upper frame to essentially the bottom of the engine drops the center of gravity and aids mass centralization, a huge issue for all these modern 4-strokes. "A lower center of gravity really helps the bike have a lighter, more nimble feel," assures Yamaha Technician and Test Rider, Mike Ulrich. Also like the YZ-Fs, the upper tripleclamp is forged aluminum for weight reduction and greater strength. Steering on the '07 models is much like the Yamaha boys have been pumping all along, responsive and light. Also new for '07 inside the 250F mill are a new intake camshaft profile and altered cam timing to boost low-end and midrange power. Jetting changes and revised ignition mapping complements the grunt-seeking effort. Getting power to the ground as quickly and efficiently as possible in tight situations is accomplished through a series of gearing changes. Special care was taken this year to ensure that the WRs are at the forefront of the quiet Thumper movement. Claimed to run at 84db, the '07 bikes are noticeably quieter than in past years. One final performance note is the addition of wave-style rotors, another YZ-F trickle-down. The 250mm front disc is the better-performing of the two and gives very good feel at the lever.
