Performance like a Vespa racing exhaust - Looks and acoustics almost like a standard exhaust

Purebred Vespa racing exhaust

The BGM BigBox Sport is a thoroughbred racing exhaust, in the unsuspicious design of an original exhaust. It positions itself as a clear alternative to eye-catching and mostly loud and large resonance exhaust systems. the high motivation clearly sets it apart from other boxing systems. Designed for performance-oriented drivers who appreciate the benefits of an inconspicuous vehicle.

The performance potential of the BigBox SPORT grows with the engine concept

Like any good racing exhaust, the Sport Box requires a powerful engine concept in order to be able to develop its full performance. Around cylinders like that Polini 210, Malossi MHR and Co. it offers impressive results. See performance diagrams from test runs on our in-house Scooter Center Dynamometer further down.

It also supports engine outputs above 25PS without any problems and pushes ahead with full torque. Despite their high peak performance the Sport Box rises with one early high torque and also enables comfortable driving.

Due to its consistent design for a high gas throughput, the BigBox Sport is not intended for use with near-series engines or tame tuning cylinders. It needs a clear and powerful discharge impulse to get the large volume and the thick elbow to fill the Sport Box with life.

PRO:

• Original optics
• Top performance like a resonance exhaust
• No performance hole
• Broad speed range
• More top speed
• Very unobtrusive
• Also fits rally / sprint without modifications
• Solid construction with clamp on the cylinder
• Handmade in SPAIN

CON:

• Not for vehicles with 8 inch tires (ground clearance too low)
• Not for near-series engines

Fixing and assembly

The assembly is easy. The elbow is attached to the cylinder using a clamp. The sealing is done for the different outlet pipe diameters in the 200cc models by insert plates. Compared to a loose fastening with an O-ring seal, this results in the best stability and prevents damage to the outlet flange. A long spacer on the rear shock absorber could be used for even greater ground clearance.

And finally ...

Pure understatement. Performance like a racing exhaust, optics and sound similar to an original exhaust.

Depending on the engine concept, the BigBox, just like a resonance exhaust, can significantly increase performance.

The Vespa BigBox in the test

BigBox SPORT on 12PS Vespa PX200

Even as a classy racing exhaust, the BigBox SPORT can mobilize more torque on a 12 HP original Vespa engine in the upper speed range. In comparison here against an old friend, the Sito Plus. But then things really get going on a tuned Polini or Malossi engine. See below.

Bigbox SPORT with Polini 207 cast iron

The BigBox Sport provide more power and torque.

With this engine, further processing of the Einalssform and one bgm Pro crankshaft sure to achieve even more power and, above all, torque in the lower speed range.

 

bgm PRO BigBox SPORT from Malossi MHR

The BigBox feels really good on engines that are built in the house large canal areas offer and generally that Potential for a little more performance to have.

Here on a motor with 59mm stroke bell shaft (57mm stroke with eccentric crank pin) and plugged in Malossi MHR (Spacer at the cylinder base 1,0mm, cylinder head gasket 0,5mm).

 

With main stand

Of course with the PX but even with Vespa Rally, Sprint, GT, GTR models the main stand still fits!

To accommodate the manifold length on the vehicle was not really easy, it took us a few tries to find a course that was as close as possible fits many vehicles and does not collide with the main stand or the footplate.

With the Rally, Sprint, GT, GTR models, the distance to the stand feet is often critical in connection with a 200 engine. With the BigBox Sport, we made sure that there was enough space here and on the main stand.

Maximale Bodenfreiheit

Although the BigBox lives up to its name due to the design, we also took the appropriate ground clearance into account when laying it.
As usual with the Largeframe Models, as a rule, only have the kick starter screw and the gear shift in contact with the road.

However, we have to advise against using the BigBox Sport for the 200 cc on vehicles with 8 ″ tires.

Please check the clearance of the elbow to the footplate and the roadway. In individual cases, you can still correct this with a longer spacer on the rear shock absorber.

Bigbox TOURING for 10 "and 8" Vespa

We are working on the touring version of the BigBox for those who love engines that deliver their torque at low speeds. This will then also be suitable for the 8 ″ models.
