400's
 

Think I got the explorer sold and gonna look for a 400 2 stroke 2 wheel drive. Are there any differences between a sport 400, trailblazer 400, or scrambler 400 2x4 other than name? Also what years are better than others, like features or problems? thanks

those are all basically the same machines. look around there are many available. imo, i would stay with at least the 99 & up. they are concentric drive, not that there is anything wrong with the non-concentric, i just find a few less drive train problems with it. the scram 2x4 has the better rear shock, but that can be put on any at reasonable cost, and also braided lines. i switch my 99 over to the wilwood brakes with braided lines. also, youll get a steering post bearing rather than the bushing like on earlier models. plenty of mods for any of them. Good Luck.
