What are the differences between the Scrambler-sport frame VS the Trailblazer 250 frame. The reason I ask is I'm looking for a rolling chassis to fit a CFI 700 motor into for a dune machine to drag up the hills at Saint Anthony. Also what years have the best suspension Thanks for your help.

 

the frames are pretty much the same, you will need to reinforce the tranny mounts or run a jackshaft to not tweak the frame.

theres concentric and non concentrics, depending on year, but there the same across all three models for each style. use a 4x4 tranny and remove the output shaft its a gear case as opposed to a chain case.
