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.

It also fits Vespa V50, 50N, 50 Special, V90, SS90, 90 Racer, V100 models converted to 125cc (or larger).

The BGM Pro Banana in the SPORT version offers a discreet look with the
performance values of a racing exhaust.
It resonates from about 5000 revolutions per minute and then pushes forward with great emphasis.
It is currently the strongest exhaust system available in the characteristic banana-shaped design of the standard exhaust of the Vespa ET3 models.

The BGM Sport Banana harmonizes very well with a powerful road tuning
based, for example, on the Polini 133 cylinder. The relatively low split manifold
allows, like an original banana exhaust, a
quick removal of the exhaust body. The connection is secured by
traction springs that are stable but can be quickly detached.

It is recommended to increase the jetting

MATERIAL The bgm PRO Touring crankshafts are forged. The material is denser, so it dissipates heat better and is therefore more resistant to distortion. In addition to the crank webs, the connecting rod is also forged and then CNC machined. LUBRICATION
The lower connecting rod bearing is lubricated via two large lubrication slots and a total of four additional pockets on the side. The SSC rolling bearing and side thrust washers provide a solid bearing. The lubrication of the upper connecting rod bearing is done through two lubrication holes. The INA piston pin bearing is included with the crankshaft.

The shaft is available with a long stroke of 60mm (long stroke) and with a 57mm stroke
(standard). With the long stroke version, you get a larger displacement, while at the same time the cylinder control angles (overflow and exhaust ports) can be modified to increase performance. GEAR ANGLE Compared to many other racing shafts, the bgm PRO Touring shaft has a much better intake layout. For
tuning cylinders, the standard wave, with its very short intake time, cannot keep up with the standard wave. The bgm PRO shaft, on the other hand, closes on a PX engine

PERFORMANCE EVERY DAY The BGM177 cylinder is
a very powerful, durable, and completely
everyday conversion cylinder. It covers a very wide range of applications. Simply
by swapping the cylinder, you can more than double the power of the standard
125cc engine and easily ride the wave of great torque.
Similarly, the exact same cylinder can turn the engine
into a beast with over 20 HP if it finds the right environment (carburetor,
exhaust, crankshaft). Thus, the cylinder offers beginners a
perfect base to be able to expand this, as needed,
more and more. The BGM PRO 177 replaces the original cylinder,
the conversion is simple and easy to reverse if necessary.
With its large displacement of 177cc, the BGM PRO 177 always offers
a safe and relaxed driving experience. The engine is as powerful as a
200cc machine, but with exactly the same reliability and durability.
It achieves this by operating in the same RPM range as a standard engine. The
low fuel consumption and the high range associated with it are

The advantages are a lighter clutch that separates more quickly and is extremely durable.
Despite the seemingly smaller pad surface, the clutch with the CR pad type can transmit more torque with the same elastic force. For this, only the effective radius is decisive, not the size of the friction surface as such (this is only relevant for wear).

Thanks to the extremely durable pad material, CR pads can also be used in very powerful engines in everyday use. A major advantage is the taller clutch discs compared to the
original discs.


RECOMMENDATION We also recommend a low-alloy gear oil of API GL3/GL4 classes for high-performance engines to prevent clutch slippage even under extreme loads.

Note: The entire lining package is approximately 1 mm lower with these linings

After installing the clutch, check if the clutch touches the clutch cover. If necessary, rework the whole thing or use an outward-facing cover. Alternatively, you can use the spacer ring we offer separately

Size--> 2.10-10" with pre-installed valve

WEIGHT REDUCTION The weight saving compared to an original PX steel rim is 600 grams. Additionally, there is a weight saving of about 370 grams due to the no longer necessary tube. The unsprung masses are thus reduced by almost one kilogram per axle (over 64%). The response behavior of the frame improves significantly.

SAFETY
Due to a so-called double "hump" in the rim well, the tire is always safely guided in the rim. Similar to the latest run-flat technology in the automotive sector, if a foreign object (nail or similar) is pushed into the rim, the air can escape slowly without the tire slipping into the rim well. The vehicle stops in a controlled manner. The rim has recesses between the bolting points. Brake cooling is improved.

SPECIAL FEATURES The track offset is 2.5 millimeters on the left side. Mounting aluminum rims on both axles equalizes the track offset. This is not noticeable while driving. The rim does not have a test mark and is not road legal.

For tubeless tires (TL)

Some Malossi V-One/VR-One engine housings have very deep holes for the silent crossbar rubbers. To prevent the engine from moving laterally and potentially touching the frame, we offer special spacer bushings.

The primary BGM wheels are bulletproof. Developed for the immense power and torque of today's engines, they are made of high-alloy steel (SCM415 / 15 CrMo 5) according to the highest production standards. The enormous strength of the base material (up to 1100N/mm2, HRC 58-62) provides a safe and reassuring foundation for the production of BGM primary wheels.

Thanks to the possible combination with BGM Pro straight-toothed clutch pinions

The Superstrong 2.0 CR clutch 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. Thus, it offers perfect clutch engagement with a well-defined biting point and a clean cut. It is suitable for both the touring rider who appreciates high quality and the ambitious racer seeking an extremely robust and stable clutch.

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 strength. The spring rate is significantly tighter than that of an original spring. Ideal for high-performance engines.

Developed for the high performance and torque of today's engines, they are made of highly alloyed steel (SCM415/15 CrMo 5), in compliance with the highest production standards. The enormous strength of the base material (up to 1100N/mm2, HRC 58-62) is a reliable foundation for the production of BGM sprockets.

The production meets the high standards in place for Honda gear manufacturing. Each individual piece is accompanied by a test report, allowing BGM to have continuous and lasting quality assurance.
