Used 65cc Metra Kit cast iron kit for Derbi Flat Reed.
We found this cylinder on an imported Derbi Variant Sport that we rebuilt. The bore of the cylinder is in great shape! The piston is in poor shape.
The scuffs on the piston could be smoothed out and maybe you could use it with new rings but we'd recommend a new piston. The 43.5mm Airsal piston for the new style aluminum kits would be a perfect replacement. Just notch the skirt to match the original and you're in business.
