New edition of the Due+ by TOP PERFORMANCES. The Replica cylinder of the world race record in Nardo has been further developed and now has the cylinder head, called modular, divided in two. Cooling water now better wraps around the cylinder head and thus improves cooling power. The utility must be seen more from a visual than a technical point of view, since with simple cylinder heads there have never been any cooling problems. From the point of view of performance, there were no problems. As with all Mid-Race cylinders, you should drive a 17.5mm and proper exhaust; to improve performance and durability, we can recommend the Nardo exhaust of the TOP PERFORMANCES and the discharge YASUNI C16.
