My son rides a 02 yz125. He doesn't motocross, but on a rare occasion takes it to the tracks. Mainly, he rides desert and longer rides with guys on their 4 strokes. That is the type of riding he prefers, but loves having the power and weight of his 2 stroke. He is of interested in making the YZ a "desert bike". Anyone suggestions out there of what he should plan on doing and buying? Anyone do this to their bikes?
