WIDE FRAME ENGINE ISSUE: The BGM Pro and Corteco oil seals, which are of much higher quality, are available (for safety reasons) only with a 0.8 mm sheet metal coating. If they are installed in a wide frame engine, the crankshaft bearings deform, causing damage to the bearings.

WIDE FRAME ENGINE SOLUTIONS: The circumferential bead of the oil seal is flattened, reducing the height of the oil seal plate by about 0.3 mm. The bearings then run freely. b) The BGM Pro bearing set with special FAG 9-ball bearings. In this case, the shoulders of the bearings have been custom machined to ensure stress-free mounting of the crankshaft bearing. The set includes high-quality resistant BGM Pro FKM/Viton® oil seals.

The new BGM Pro Touring muffler is a true wolf in sheep's clothing: a powerful sports exhaust that perfectly blends into the inconspicuous design of a standard exhaust. Thanks to the innovative design of the BGM PRO Touring Box, with the flat diffuser opening angle and moderate resonance length, it optimally adapts to different cylinder concepts. The result? A wonderful touring machine that moves with great thrust even at low revs.
Perfect on tuning cylinders like BGM150, Pinasco160, or CC Corsa 160/175

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
