Our racing exhaust for Vespa has been tested again. And once again it is the test winner with the greatest power delivery. In this case, our BigBox for the Vespa T5 was tested by the British online scooter magazine SLUK tested. Here is a video of the test:
now The bgm BigBox Vespa T5 is designed as a replacement for the already sensationally good original exhaust system of the Vespa PX special model T5. The T5 engine designed by Morini has some special features due to the adapted powerful 125cc motorcycle cylinder.
Conclusion
The diagrams clearly show that our bgm BigBox harmonizes with the original engine as well as with Polini 152 or Malossi 172 tuning cylinders. On revised engines, the larger volume of the BigBox Touring results in a significantly better torque and power curve than with the original exhaust.
