Vortex VTM, Mini60

• Piston Port
• 2 transfer ducts intake
• Integrated electrical starter
• Centrifugal dry-clutch
• Mixture-lubricated
• Cast iron made cylinder CNC worked

The innovations introduced by Vortex Engines, however, were not only limited to the restyle of the engine components, but also involved the updating of its manufacturing processes. The VTM, in fact, benefits from an additional manufacturing process, the paired crankcase boring. 

This additional machining phase of the engine crankcase makes it possible to achieve a higher final quality level of the product with positive effects both in terms of quality and repeatability of the various models produced as well as in terms of performance and reliability. On the other hand, those features necessary for the engine to comply with current CIK-FIA homologation regulations remain unchanged, such as the maximum speed set at 14,000 rpm.
