Lambretta resonance exhaust and big box prototype test
A Lambretta exhaust test: the new and upcoming Lambretta big box is currently in production. Unfortunately, a delivery date is still unknown.
The Lambretta exhaust systems in the test
Before we sent the final sample to Spain, the new box was put through its paces. Lambretta exhaust test: Another prototype box from our friend Chalky from Replay Scooters and
JPP was also put to the test:
- bgm PRO BigBox Proto
- JPP Box Proto
The following resonance racing exhaust systems competed against the boxes:
- the TSR Evo,
- the JL3 and
- in MB3
And all three resonance systems performed better against the boxes than we would have expected!
The Lambretta engine
The test engine was constructed as follows:
Result & conclusion of the test
Nice and clear to see how well the box scores right from the start not only with
power, but also with
plenty of torque compared to the 'racing exhaust systems'. This is precisely what makes the bgm PRO boxes so nice to ride. Sufficient power is always available without having to struggle with gear connection problems or having to twist the throttle like crazy to get going. The moderate consumption values of the engine concepts with the bgm boxes are a further advantage, apart from the original look and pleasant background noise. Another outstanding feature is the protected mounting system with horizontal and vertical adjustment options. This allows tolerances and, above all, the spacers used for different strokes and connecting rod lengths to be compensated for.
