Picked this up on Friday -
It's a blast to ride. It has an Arrow chamber and a Mikuni flatslide. Pretty soft until about 7500, but then pulls strong to 11,000.
I need to clean it up and do a few things. Planning to powder coat the wheels blue to match the graphics, get some new tires (same sizes as the pregen), remove a few unnecessary parts, and add some neat finishes here and there.
Euro riders are probably familiar with it, but most U.S. riders have never heard of Derbi.
It's a 2-stroke 50 from Spain.
EDIT: Just figured out this one has a factory 75cc engine, and supposedly only 200 were imported.
