The new BIG BORE Ø 50, stroke 39,2-39,3 and 44, cylinder kits comes from the technology of the famous Malossi 7 ports cylinders. They are designed for both Minarelli and Piaggio engines.
All pilots, thrilled about the news, wished to test them. The expectations were not disappointed : the power increase and the absolute reliability proved, once again, the high quality of the products and Malossi professionalism.
