Specific for Malossi cylinders 3116326 - 3115829

TECHNICAL FEATURES

Half-shaft material: 18 Ni Cr Mo5.
Monolithic forged half-shafts and rotating masses.
Machining on high-precision machine tools.
As many as five heat treatments on all components.
High surface finish to improve reliability.
Dynamic balancing up to 16,000 rpm.
Forged connecting rod in 18 Ni Cr Mo5 copper-plated, coupled to the shaft with a precision roller bearing for high speeds.

An exact replica of the original PIAGGIO base produced for the Ciao, Bravo, Si, etc. mopeds, suitable for standard and modified engines.

The supply includes all the nuts, bolts, and washers necessary for assembly, the cylinder mounting studs, and also both crankshaft bearings.

In these thermal units, the characteristic of high durability of cast iron combines with the almost obsessive quality standards of Malossi, one of the very few companies demanding the maximum even from this class of thermal units.
In this perspective, the very strict selections for the coupling between the cylinder and piston are strictly maintained within the range of 20 microns maximum tolerance.

The Malossi range for the Vespa offers products of extremely high technology capable of developing performance increases so exceptional compared to the standard, that they require the adaptation of other fundamental components of the vehicle as well.

Just compare a Vespa PX 200 E produced in 1978, which originally develops a power of 12.35 HP at 5700 RPM, with a Vespa "tuned" with Malossi Kits, which can develop 27.5 HP at 8000 RPM, that is, more than double the HP at an extremely higher rotation speed, to understand that it was absolutely necessary to design a clutch group capable of withstanding the stresses due to such a performance increase!

The Malossi POWER UP CLUTCH SYSTEM clutch groups are designed to provide a solution and overcome all the problems that inevitably arise when the clutch group's technology is not adequate to the other engine components. A traditional clutch, having to transmit to the gears more than doubled power, while having to rotate much faster, can lead to failures of the bell under the effect of centrifugal force, to slipping and deformations that result in annoying and not very reassuring metallic noises, up to the classic clutch slippage caused by the insufficient friction developed by the

The V-One is designed for those who want a casing perfectly replaceable with the original, provided with all the components necessary for assembly and allowing maximum interchangeability with components available on the market, it requires no aesthetic modification of the vehicle and fits all original Piaggio parts.

The crankcase seats are designed to accept the original crankshaft bearings and seals (not provided). V-One can be mounted with the original Dell’Orto Si 24-24 carburetor.
It is possible to use the original crankshaft or our rotary valve crankshaft with a 57mm stroke art. 5316082. Whatever the choice, the intake has been reviewed and implemented thanks to our modern
CAD systems that have profiled an optimized intake duct in the casing.

The new Malossi MHR grips aim at a trio of elements: design-safety-comfort.
Every detail has been designed and defined based on these three elements, essential for an aggressive design, grip safety, and comfort while riding.
In particular, the design promotes vibration absorption, the dimensions ensure a secure and manageable grip, and the ergonomic structure allows the palm to rest without inflaming the forearm.

The Malossi MHR BLACK grips are made with a thermoplastic rubber with high mechanical characteristics and excellent heat resistance, the result of long research aimed at selecting special polymers with high elasticity and soft touch. This material guarantees the MHR BLACK grips resistance in all usage conditions and, consequently, great durability. Finally, the soft touch provides a pleasant and comfortable sensation to the user.

MHR Version: The MHR version differs from the SPORT one not only in the exhaust port, but also in the decidedly racing transfer diagrams.

Malossi power exhaust has been redesigned, increasing the power compared to previous models by about 5%, thanks to an in-depth study that involved the internal surfaces of the sheet metal with which the expansion is made.
