Malossi has taken the design of performance parts to the next level. The introduction of their Malossi Crankcase Kit C-One has revolutionized scooter tuning by presenting innovative technology ready to house the latest and newest racing components.
To date, riders were forced to equip their tuned racing scooters with original or OEM quality crankcases that were designed for limited power and performance. They had to modify these crankcases so they were capable of dealing with the requirements and strain of 70cc and more powerful engines. But times are a-changing, and Malossi's C-One crankcase, developed and manufactured in Malossi's Research & Development centre, represents a milestone in building the ultimate racing engine.
Malossi basically started from scratch, discarding traditional concepts in crankcase design, and came up with a completely redesigned transfer and inlet port area with short stud bolts while at the same time increasing structural rigidity.
Special attention was paid to the reed valve area - employing the newest CFD (Computational Fluid Dynamics) software, Malossi engineers were able to calculate and design optimum angles and dimensions for reed valve placement.
They got rid of auto-lubrication and traditional water pump technology in order to minimize power loss, a pre-drilled opening allows for the use of a vacuum fuel pump. The opening for the electric starter was closed. Shock absorber mounting was redesigned and reinforced.
The C-One for Minarelli is based on the C-One for Piaggio; this means that you'll have to use Piaggio components. You can use standard Yamaha / MBK wheels with disc brake. The crankcase was designed for Malossi MHR cylinder kits.
