My buddy is hooked after taking my beaten 1988 XR250R for a spin. He's now looking to buy a bike like mine since he enjoyed it so much. He's about 5'11", 225#, looking to spend about $1500. He's currently a novice rider (used to ride when he was a younger) but I am sure his skill level will quickly improve as he gets more seat time. Reliability/durability is most important, then size (will fit his build) and price is important too. It seems most of the major manufacturers had a decent 250 thumper trail bike during the 80s-90s. An XR250 is an obivous choice, but also maybe a Yamaha TT/TTR250 or something from Suzi or Kawi? Maybe something bigger (400cc)? Thanks in advance.
