The challenge

The Vins Duecinquanta is an innovative high-performance motorcycle featuring an uncompromising design and a number of advanced engineering solutions that set it apart from conventional sport bikes.
At the heart of the motorcycle is a unique hollow carbon fiber monocoque chassis. This multifunctional structure integrates the steering head, radiator, fuel tank, and engine into a single load-bearing component. In addition to providing structural support, its internal geometry also acts as an air duct, extracting and directing hot air through the motorcycle to improve cooling efficiency.
Although the first functional prototype successfully demonstrated the concept, its weight exceeded the original design targets. The objective of the project was therefore to optimize the composite laminate schedule, reducing the mass of the monocoque while preserving—or improving—its stiffness and structural strength.
Composite optimization is inherently multidisciplinary, requiring expertise in structural mechanics, material engineering, and manufacturing. The challenge was not only to maximize mechanical performance but also to simplify production and reduce manufacturing costs without compromising the motorcycle’s exclusive character.

Our contribution

SmartCAE supported Vins Motors in redesigning the composite laminate of the Duecinquanta’s carbon fiber structures to improve structural performance while streamlining the manufacturing process.
Starting from the original CAD design, we developed detailed finite element models of the motorcycle’s primary structural components, including the carbon fiber monocoque chassis, rear swingarm, steering head, and front swingarm.
Using the design load cases provided by Vins Motors, we identified the highly stressed regions requiring additional reinforcement as well as low-stress areas where material could be safely removed to reduce weight.
Working closely with the manufacturing team, we also evaluated alternative composite materials and laminate configurations aimed at simplifying production, reducing raw material costs, and improving overall manufacturing efficiency.

Benefits for the client

SmartCAE’s extensive expertise in composite structural engineering, finite element simulation, and carbon fiber manufacturing enabled Vins Motors to rely on a single engineering partner throughout the optimization process.
The project achieved outstanding performance improvements, including a 41% reduction in component weight, a 47% increase in the torsional stiffness of the carbon fiber monocoque, and a 50% reduction in composite manufacturing time.
By combining advanced structural simulation with practical manufacturing expertise, SmartCAE helped Vins Motors enhance the performance of its ultra-lightweight motorcycles while simultaneously improving production efficiency and increasing overall product profitability.
