What does the MALOSSI banana bring?
With the Vespa Largeframe have powerful exhaust systems, so-called Box exhaust systems, established in an almost original look. We have with the bgm PRO BigBox Touring and the Big Box Sports 2 optimized BigBoxes in the program.
Scooter Center - home of bgm
This development also applies to the Vespa Smallframe Indent.
Since we are with the bgm PRO BigBox Banana are also working on such an exhaust system, we have them Malossi banana used directly for a comparison.
Bananas among themselves: Malossi VS Road Banana
Here in direct comparison to the previously available road banana.
From a purely visual point of view, the two exhaust systems initially differ in the pressed manifold at Malossi and the manifold made up of segments in the road system.
The test engine for the bananas
For our tests we used a proven engine, like the one in class 5 (K5) of the European Scooter Challenge is used.
With well-known components that can only be plugged together in this class, this motor concept is both simple and durable and can be reproduced at any time. So no exceptional super special professional unit, but down-to-earth home cooking that is fun over the long term and can be easily set up by anyone.
Our test engine therefore consists of the following performance-influencing components:
- Crankshaft: Mazzuchelli Racing, ETS
- Cylinder: Polini 133 Racing
- Carburetor kit: Polini membrane with Dellorto PHBL24
On the diagram you can see that the Malossi banana is slightly above the road banana.
In the range between 5500 rpm and approx. 6700 rpm, the Malossi exhaust is slightly ahead.
Full of banana!
bgm PRO BigBox Banana
Since we are also working on an exhaust for the Smallframe work, the direct comparison with the Malossi banana was of course very exciting.
From top to bottom:
- Malossi banana
- Road banana
- bgm PRO BigBox Banana
For the purpose of better accessibility, we decided to use a position as the separation point for the manifold for the BGM-Banana, which can also be easily reached with the spring-loaded hook on the classic V50 and Primavera and yet is not in the immediate field of vision. The lower holder is designed in such a way that two springs can be hooked in here without any problems.
The super banana: bgm PRO banana brings 2PS
The BGM banana already cuts a fine figure on the test engine. So far we are quite satisfied with the results ...
Between 5700rpm and 8700rpm, the bgm Pro-Banana averages almost 2HP over Malossi.
The torque, which is important for propulsion, is also clearly in this speed range above that of the other test subjects.
Delivery date bgm Pro BigBox Banana
We hope that we will have the exhaust ready for you by the start of the 2018 season.
