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

BGM FASTER FLOW SI Carburetor - optimized carburetor for high-performance engines

High-performance engines require reliable and consistent fuel supply. The BGM FASTER FLOW carburetor is designed to meet these needs, using the Dell'Orto/Spaco SI24/24E or SI26/26E models. Each unit is completely disassembled, tested, reworked, cleaned, and carefully reassembled in our factory, ensuring the highest quality for modified engines.

Main modifications:

Enlarged connection holes from the float chamber to the nozzles
Added a hole in the float needle area
Spring-loaded float needle for increased durability
These modifications significantly improve fuel supply, preventing shortages even with powerful exhausts. In particular, the spring-loaded float needle compensates for vibrations and increases durability, while the optimized supply is also advantageous for stock engines.

Advantages:

No nozzle blockage with powerful exhausts
Easy tuning even with over 20 HP
Quiet, powerful, and suitable for everyday use
Available for mixed or separate lubrication
Suitable for:
Engines with SI20/20D or 24/24E carburetors

We subjected the set to a long and thorough stress test on the road and highway. The result is so convincing and reliable that we can now offer it as a set for the expert mechanic.
It allows the use of a Malossi 210 Sport cylinder from the PX200/Rally/Cosa models on the engine casings of the Vespa Largeframe models starting from 1977, the date from which the engine casings were converted to three transfers.

ADAPTER SET
The conversion is based on a crankshaft with rods 20 mm longer (125 mm instead of 105 mm). The solid CNC machined steel adapter plate is bolted to the engine casing and accepts the studs for the PX200 cylinder. A 1.5 mm thick aluminum gasket between the adapter plate and the cylinder base seals the screw holes and establishes the correct installation height.

MALOSSI SPORT
adapter set 07-AA-179-IR is designed for use with a Malossi Sport 210 cylinder. For this purpose, however, it is absolutely necessary to remove the spindle from the engine casing, as the Malossi cylinder base cannot be shortened without losing stability.

The BGM PRO 177cc is an improved and more powerful version of the proven BGM177 cylinder for Vespa PX125/150, now also compatible with models equipped with electric start.

Everyday Performance
The BGM177 cylinder is designed to offer high performance, durability, and reliability for daily use. By replacing the original cylinder, it is possible to double the power of the standard 125cc engine, with generous torque that allows for smooth riding. The cylinder can also be configured to reach over 20 HP, provided the right carburetor, exhaust, and crankshaft are paired with it. It is therefore an ideal solution for beginners who want to expand performance in the future.

With a displacement of 177cc, the BGM PRO 177 cylinder ensures a safe and relaxed riding experience, maintaining the same reliability and durability as a 200cc engine, operating within the same RPM range as a standard engine. It also offers low fuel consumption and good range. It is compatible with standard components, requiring only a small adjustment to the carburetor jet and spark plug.

Main Features
Material:

The bgm PRO clutch springs are produced in Germany and are subject to continuous quality control. The material used, Oteva70®, makes the spring block stable and true to size. The spring does not deviate laterally until it is blocked, and once unloaded, it returns to its original length. The clutch spring retains all its elastic force. The spring rate is significantly narrower than that of an original spring. Ideal for high-performance engines.

BGM PRO Super Strong clutch What is a plug and play solution - Made
in Germany. You get a ready-to-install clutch product with reinforced
clutch springs that works well in a power range up to 20hp / 22Nm. With
stiff springs available separately, the clutch does not disappoint, even with configurations of more than 40 hp.

Sealing kit included with the BGM cylinder
This kit includes three base cylinder gaskets and one head gasket.

Gasket thicknesses:
Base gaskets: 0.2mm, 0.4mm, 0.6mm in aluminum
Head gasket: 0.5mm in copper
The variable thickness of the base gaskets allows for optimizing control angles according to specific needs or stroke. For fine adjustments, aluminum spacers for the head are also available.

The shock absorbers from the BGM PRO SC series are the ideal solution for adjustable Vespa suspension, approved with TÜV certificate.

The BGM Pro TOURING exhaust offers a significant power increase
on short-stroke engines in the original look. True to its name,
the touring exhaust system is ideal for a fast street engine,
powerful yet visually and acoustically unobtrusive. It harmonizes
very well with common tuning cylinders from 75-112cc displacement, but it is
also clearly superior to the stock exhaust on a standard
50cc engine.

The performance level and ground clearance have been significantly increased compared to the previous version.
The new Touring revs significantly higher than the previous BBT.

The exhaust pipe has been expanded from Ø18 mm to Ø20 mm. However, to reduce noise levels, the BBT2 is equipped with an exhaust pipe inserted inside the Ø20 mm one with Ø18 mm.
This section is sufficient for almost all engines up to 190cc and about 22-25HP (this value varies depending on the engine structure and the achievable RPM).
Those who drive a very powerful setup with high continuous RPM can remove the Ø18mm exhaust pipe, which is fixed with only one weld point, and thus have the full Ø20mm section.

With the Sport and Competition line, BGM Pro offers two series of high-quality shock absorbers in its product range. Both share perfect workmanship, high-quality materials, and ABE approval. The shock absorbers are very lightweight despite their high load capacity because they are made of high-strength CNC aluminum and have an exceptional hard anodized surface protection. The front shock absorbers are 15 mm shorter than standard shock absorbers, thus lowering the front of the vehicle. This benefits driving stability, top speed, and, not least, the aesthetic appearance. Additionally, the swing arm angle is reduced, which improves the damper response. The resulting larger wheel stabilizes handling at higher speeds.
