Introducing the new 2010 Yamaha YZ250F. The key development concept behind this awesome new machine is excellent cornering and handling performance. In other words, the new 2010 YZ250F “does exactly what the rider wants”.

The year was 2001 and Yamaha introduced the first modern 250cc 4-stroke motocrosser. We have taken the original concept of “Ultimate Quick Turn Performance” and elevated it to an entirely new level.

The all new Bilateral Beam aluminum frame centralizes mass for exceptional cornering and handling performance. The 250F is more compact than the pervious generation chassis for superior cornering. The optimized engine delivers a new level of power in the low-to-midrange, with a great torquey feel, exactly where riders want it. Mix in improvements to the intake and exhaust system, lighter valve train, new carburetor settings and you have a winning combination that will be hard to beat.
