scooter racing mhr big bore ø 52 exhaust system

商品說明

The perfect musical instrument to make your Malossi motor sing.

Scooter Racing Malossi exhausts are designed and built with one objective: maximum possible performance tuned to the cylinders for which they were designed. Every evolution of Malossi exhaust systems is the result of fluid dynamic research which establishes the ideal shape and size of Scooter Racing exhausts with precision.

Only perfect exhausts with a completely uniform production process can proudly display the Malossi brand. Indeed, the production technology is applied to all Scooter Racing models, the only differences between them being the divergence of the cones.

All Scooter Racing exhausts are made from sheet metal of a precise and constant thickness of 0.8mm, are laser cut and welded with pinpoint precision, and have a calibrating nozzle whose size respects the minute tolerances needed to maintain pressure inside the silencer at the correct levels.

The development of Scooter Racing exhausts advances at the same rate as Malossi cylinders and in order to get the best performance, it is important to match the exhaust to the cylinder for which it was designed.

All Scooter Racing are fi tted with aluminium silencers, anodized in Nitro Blue.

MHR TEAM 3 and MHR BIG BORE Ø 52

MHR Team 3 and MHR Big Bore Ø 52 are the NEW Scooter Racing exhaust names designed for Testa Rossa Flanged Mount cylinders, 70 and 94 cc respectively, and are characterised by an unprecedented cone profile, now rotated vertically, for an even more dynamic appearance.

Malossi engineers have managed to considerably increase power and have paid particular attention to rounding of its usage range, in order to increase the fi eld of action and fine tune the assembly more quickly. There is a high rev range for the motor and the best power levels are achieved at 14,100 rpm for the 70cc, and 13,800 rpm for the 94cc.

The assembly system on the cylinder uses an attachment with four light alloy holes, designed to allow a perfect flow of exhaust gases, and so optimising fluid dynamic flow. This solution is a direct development of the technology used by the MHR Team 2 exhaust, where as it is unprecedented on the Big Bore Ø 52 version.

The connection system for the Nitro blue anodized aluminium silencer has been simplifi ed, and is now linked to the expansion chamber in a light and elegant way, using only one holding screw.
