Anyone who has ridden Yamaha's YZ250F can appreciate its well-roundedness, but it always comes across a little like our favorite mellow dairy product. This year, Yamaha has tried to give its smallest motocross thumper some added flavor, and succeeded! Though certainly not ground-breaking by any means, the 2009 Yamaha YZ250F has received enough attention from the Tuning Fork gang to make it a better machine. Most changes focus on expanding rider adjustability and minimizing maintenance requirements. Hence, there's very little that pertains to the performance gains, but a few tweaks was all it took to breathe a little excitement into the popular 250F.
