We are proud to unveil the all-new MONZA-X 3.5cc, the latest expression of our high-end racing philosophy for the 1/8th on-road competition class.
The MONZA-X is the result of decades of hands-on experience in precision manufacturing, advanced material selection, and surface treatment technologies, combined with an intensive development program carried out throughout the 2025 racing season. Every component has been designed, machined, and finished with a clear objective: to deliver uncompromising performance with absolute reliability.
At the heart of the MONZA-X lies an all-new, exclusive 10-port cylinder, entirely developed in-house. Its port layout and internal geometry are the result of extensive fluid-dynamics studies and track validation, providing a substantial increase in power output while maintaining excellent fuel efficiency and thermal stability.
The long-stroke architecture has been carefully engineered to generate strong and consistent torque across the entire RPM range, resulting in outstanding drivability, immediate throttle response, and superior acceleration out of corners. This makes the MONZA-X both extremely fast and remarkably easy to exploit at the limit.
To ensure long-term durability and mechanical efficiency, the engine features a DLC-coated crankshaft, specifically treated to minimize friction, reduce wear, and protect against oxidation. The rotating assembly is completed by a 14 mm rear Swiss ceramic ball bearing and a meticulously aligned knife-edged aerodynamic connecting rod, designed to reduce turbulence and mechanical losses at high RPM.
Supplied with an 8.5 mm venturi, the MONZA-X 3.5cc stands as a true top-tier racing engine—crafted for demanding drivers who expect maximum performance, refined engineering, and race-winning consistency, lap after lap.
