Description

Crankcase for all scooters that fit a Piaggio 50cc 2T engine as original equipment

This crankcase has been dreamed of and brought to reality with just one aim in mind: to produce the most innovative racing component for scooters that has ever existed.

A revolution cannot be considered as such, if it does not involve a radical change. That's the reason why Malossi decided to go beyond the C-One crankcase, thus realizing RC-One, an even more extreme version dedicated to those who love high-powered engines.

With the release of RC-One crankcase as well as the new MHR Flanged Mount cylinders, the engine capacity achieves 94 ccs and the power largely exceeds 30 hp, without any problems of boring or resistance involving the engine block.

RC-One is designed to use exclusively Malossi cylinders with flanged mount; inside it has a housing of such dimensions as to allow the installation of long-stroke crankshafts without any further modification.

MHR C-ONE was conceived and designed to:

  • Fit both drum brake and disc brake.
  • Replace the original engine both with short and long wheelbase (even on 12/13'' wheels). The position of the shock absorber fixing has been designed to satisfy both options.
  • Fit exclusively the brand-new Malossi MHR Ø 52 Flanged Mount testa rossa cylinders, with flange mounting and a housing of such dimensions as to allow the installation of Malossi RHQ crankshafts with stroke 44 and connecting rod 90, without any further modification.
  • House exclusively the Malossi MHR and MHR TEAM inner rotor ignitions.
  • Use an electric cooling pump to eliminate the power consumption of the traditional mechanical water pump.
  • Eliminate the automatic mixer.
  • Designed to fit the vacuum fuel pump.
  • Install the new bigger reed valve, designed using sophisticated programs of 3D fluid-dynamics simulation.
  • Hold all current Malossi products.
