The 250 SX-F was once again the World Champion in MX2 for 2014 and added a prestigious 2015 AMA Supercross 250SX Championship to its amazing trophy cabinet. The 2014 season was a great success in racing at all levels around the globe and the remainder 2015 promises to be no different. Already known for its strong performance, the new generation 250 SX-F presents itself with a newly developed, stronger engine built into an all new chassis. The combination of a powerful engine in a lightweight and agile chassis is sure to make the 250 SX-F the star of the show for the future. The new 250 SX-F, the lightest and best performing bike in its class, is the right choice for both the amateur and professional rider; a winning bike that the competition will find hard to follow.
