2006 Yamaha YZ250F 50th Anniversary
Even though from a distance, the yellow livery of the 2005 YZ250F 50th Anniversary might trick you into believing you're seeing a Suzuki, this is only good-old, proven Yamaha technology. Like several other highly-popular Yamaha machines, the 4-stroek quarter-liter off-road beast got an anniversary edition.
It sports all the features and revisions of the base mode, but its livery will surely make a lot of eyebrows raise, as people draw nearer and observe the three tuning forks.
