About the 1999 Yamaha XT225

Just like the XT350, the 1999 XT225 spells dual-sport convenience, but in an even more manageable package.

This bike still comes with a very useable 6-speed transmission mated to the 223cc air-cooled SOHC single, putting the rider in control while operating the XT225 on both asphalt and single-track paths.

Air-adjustable front suspensions and a preload/rebound adjustable rear monoshock also allow fast setups when switching riding surfaces, while the generous 11″ clearance and aluminum skidplate provide glorious obstacle-tackling capabilities.
