2011 Yamaha YZ250 First Ride
Fortunately for Yamaha, and all aspiring racers, the AMA now allows 250 two-strokes to race alongside 250F machines in amateur competition.
None of our riders complained about the shock, but sorting the fork took some effort.
Yamaha altered the 250 cylinder head to increase the volume by 0.5cc and dropped the compression ratio from 10.9:1 to 10.6:1.
Changing lines through rolling whoops is simple and picking lines through corners leaves riders plenty of options.
Our faster riders were keen to keep the bike singing at all times and had no complaints about the Keihin carburetor.
All of our riders liked the lightweight (227 pounds claimed) feel and responsive aluminum chassis.
For amateurs competing in the 250 class, the YZ can be a viable option for collecting trophies.
Getting the bike to turn in rutted corners takes almost no effort and the bike glides through rough corner entries with little concern.
Yamaha hasn't done anything radical to the YZ250, but it still has a powerful, responsive engine and agile handling.
Climbing off the multitude of four-strokes and spinning laps on the YZ250 is a breath of fresh air, especially for those who like to whip.
