The famous RK racing exhaust for Derbi Variant mopeds. Often referred to as the 'Blue Baffle' since they used to come with blue baffles. This is for the later Flat Reed and Start V frames. Not your Piston Port or Pyramid Reed Derbi.
Discontinued and hard to find. One finally graces our shelves. New old stock but expect a few scratches in the clear coat. No dents or anything. Comes with some hardware and roller weights too!
This pipe screams and is ideal for your 47mm Airsal setup. Get it while you can!
