What are the benefits of the MALOSSI banana
? High-performance exhaust systems, so-called
box
exhausts, have become established on the Vespa Largeframe.

This development is also finding its way into the Vespa Smallframe. As we are also currently working on such an exhaust system with the
bgm PRO BigBox Banana, we have used the Malossi banana directly for a comparison.
Bananas among themselves: Malossi VS Road Banana
Here in direct comparison to the previously available Road Banana.

The first difference between the two exhaust systems is the pressed manifold on the Malossi and the segmented manifold on the Road system.
The test engine for the bananas
For our tests, we used a tried-and-tested engine, as used in Class 5 (K5) of the
European Scooter Challenge is used. With well-known components that can simply be plugged together in this class, this motor concept is both simple and durable and can be reproduced at any time. So it's not an exceptional super-special professional unit, but down-to-earth home cooking that is fun to ride and can be easily assembled by anyone. Our test engine therefore consists of the following performance-influencing components:
The diagram shows that the
Malossi banana is slightly higher than the road banana. In the range between 5500 rpm and approx. 6700 rpm, the Malossi exhaust is slightly ahead.
Full banana!

PRO BigBox Banana
As we are also currently working on an exhaust for the Smallframe, the direct comparison with the Malossi banana was of course very exciting. From top to bottom:
- Malossi banana
- Road banana
For the BGM banana, we decided on a position for the manifold separator that is easy to reach with the spring hook on the classic V50 and Primavera, but is not in the immediate field of vision. The lower bracket is designed in such a way that two springs can easily be attached here.

The super banana: bgm PRO banana delivers 2 hp
The BGM banana already cuts a fine figure on the test engine. So far we are quite satisfied with the results... Between 5700 rpm and 8700 rpm, the bgm Pro banana is on average almost 2 hp higher than the Malossi. The torque, which is important for propulsion, is also significantly
higher than that of the other test samples in this speed range.
Delivery date bgm Pro BigBox Banana
We hope to have the exhaust ready for you by the start of the 2018 season.
