Here is the kit 50cc diameter Ø41mm of the Italian house PARMAKIT for DERBI air. This kit is a model has 5 transfers reviewed and improved, a large oval exhaust and has a clean finish. A high-end VERTEX bi-segment piston.
Indeed, a kit really nice because of its performance as the elements that accompany it. It has a specific treatment and diagrams that will give you both in couples and high diets. His transfers are expanded and reworked. Its oval escapement always improves gas flushing. The piston is a high-end two-segment model because it is directly cast by VERTEX and designed to give maximum performance to this high engine. It is equipped with 2 chrome segments treated in specific steels allowing high speeds (reduction of friction) while preserving a generous torque! Comes complete however without bolt but this is only a detail ... Namely it is one of the most solid and therefore more reliable kits on the market!
