מסקנות: "Yamaha wanted to put in an impressive debut for the '07 WR machines and Costa Rica was certainly the place to do it. From the perspective of a man who has traveled no wider than spitting distance into Canada and Mexico, the fact that I can't decide which left a more lasting impression, the country or the machinery, says something special about the Yamahas. The power on both bikes is easy to use and offers plenty from each respective displacement. New chassis offer a racier feel and look but the benefits will still translate for even the most casual trail riders.
Here at MotoUSA, we've always been fond of the WR lineup, and the new Blue keeps on impressing. One thing's for sure, after spending three days aboard these capable machines, I decided that the whole Costa Rica experience was definitely better aboard the 2007 off-road Yammies. Chances are this will be true wherever you ride.
