Vespa Engine and Parts
Engine and parts: The heart and driving force of the Vespa, the Engine and parts section is located at the rear of the vehicle, firmly anchored to the frame by two pins:
the first, at the end of the central tunnel and the second to the shock absorber.
Given its importance, the engine is composed of numerous and different parts. In a complete overhaul, it is good to check the wear of all the spare parts, paying particular attention to the crosspiece,

Crankshaft bearing and oil seal kit BGM PRO FKM/Viton® (E10/ethanol resistant) for Vespa 125/150 VM/VN/VL/VB1T/VNA/GS
Vespa 125/150 VM/VN/VL/VB1T/VNA/GS
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.

Vespa 125VM1>2T/VN1>2T-150 VL1>3T-VB1T
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

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.

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.

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.

The Superstrong 2.0 CR joint combines extreme durability, absolute reliability, and ease of use. It is the foundation of every solid engine tuning.
The solid CNC-machined clutch basket has excellent
concentricity and enormous torsional rigidity. It therefore offers a perfect
clutch engagement with a well-defined bite point and a clean cut. It is suitable both for the touring rider who appreciates high quality,
and for the ambitious racer looking for an extremely robust and
stable clutch. ULTRALUBE The latest generation Superstrong 2.0 CR clutches are now equipped with a new innovative technology: Ultralube. Ultralube
delivers (through precisely defined holes and centrifugal force)
gear oil both into the high-load hub profile (between the
clutch basket and the clutch hub) and into the clutch linings
themselves. This technology, unique in the Vespa sector,
makes the legendary Superstrong 2.0 CR clutch even more stable than
it already is. A clutch designed for eternity. PERFORMANCE
The clutch supplied ready for installation is adjusted for a

The BGM 200cc cylinder is an improved version of the already reliable and powerful original cylinder. Suitable for 200cc engines of the Rally200, PX200, Cosa200, and the Spanish models DS/DN/TX/Iris, the BGM cylinder offers an additional advantage in terms of safety and performance thanks to an exact honing of 9/100 operating distance and slightly larger transfer ports. This makes it slightly more powerful and more fuel-efficient compared to the original.
The original head can be used, ready for installation with pistons, clips, piston pins, and base gasket.

BGM BigBox Sport V2 for Vespa PX200
Performance like a racing exhaust - appearance like a stock exhaust
The BGM BigBox Sport V2 is a purebred racing exhaust for Vespa, in the unsuspecting design of an original exhaust. It stands as a clear alternative to large and flashy resonance exhaust systems. The high level of performance clearly distinguishes the BBS2 from other exhaust systems. Designed for performance-oriented drivers who appreciate the benefits of a low-profile vehicle.
NEW BBS V2
The basic concept has been maintained and only adapted to the greater requirements due to the increased power and engine displacement. The BGM BBS2 (=Big Box Sport V2) has widened pipe sections both inside the box and in the exhaust area. This effectively prevents the power fade that often occurs with very powerful engines (over 30 HP).
Additionally, the often-criticized ground clearance of the manifold has been modified. The system is now fully suitable for daily use and has the same ground clearance as a comparable resonance exhaust. Like the Big Box Touring V2, the BBS2 is now also equipped with a connection between the manifold and the exhaust body.

The BGM PRO ball crimper is an intelligently designed tool. It can be used to easily and conveniently install the gear balls with the spring into the main shaft of Vespa Smallframe engines.
Easy disassembly/assembly of the gear balls
The gear balls are held firmly in place
The main shaft is held by the tool - both hands free to mount the gear lever
100% made in Germany
Without this tool, assembling the gear claw is a true test of patience. How do you position and sufficiently preload the balls on both sides at the same time without the gear spring shooting them into the endless expanse of the workshop? It's not uncommon for the balls to simply disappear and you need new ones, of course exactly on a weekend...
With the BGM PRO tool, the job is done in no time. The whole process is so fun that you want to do it over and over again. Simply because it feels so good... Indispensable in every Vespa workshop.
