mhr 100 rc-one complete engine crankcase (for piaggio engine)

商品說明

Crankcase for all scooters that fit a ZIP MHR 100 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.

Designed to be the best housing for MHR 100cc cylinder, with no need for further processing, this plug & play crankcase is ready for assembly: every detail has been finished with CNC machining to ensure maximum reliability and performance.

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 and ed RC-One crankcases, thus realizing MHR 100 RC-One, an even more extreme version dedicated to those who love high-powered engines.

With the release of MHR 100 RC-One crankcase as well as the new Ø 52 MHR Flanged Mount Testa Rossa modular-head cylinder kit art. 3118679, the engine capacity achieves 100 ccs and the power largely exceeds 35 hp, without any problems of boring or resistance involving the engine block.

MHR 100 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 100 RC-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 Ø 52 MHR Flanged Mount Testa Rossa modular-head cylinder kit art. 3118679, with flange mounting and a housing of such dimensions as to allow the installation of Malossi RHQ crankshafts with stroke 47 and connecting rod 100, 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.
