Vespa T5 exhaust - order the test winner bgm BigBox

bgm BigBox Vespa exhaust for T5 is test winner

Our Racing exhaust for Vespa has been tested again. And again it is the test winner with the greatest performance. In that case it became ours BigBox for the Vespa T5 from UK online scooter magazine SLUK tested. Here is a video of the test:

BGM BigBox Touring for Vespa T5

The bgm BigBox Vespa T5 is designed as a replacement for the original sensationally good exhaust system of the Vespa PX special model T5. The T5 engine designed by Morini has some peculiarities due to the adapted powerful 125cc motorcycle cylinder.

The T5 engine reacts very strongly to the exchange of the exhaust system. The BGM BigBox for the T5 is based on the standard exhaust in order to keep the torque in the lower and middle speed range at a similarly high level as the standard exhaust. Depending on the setup, it can turn out a little further.

Nice to see at our customer Nino in Portugal, Original T5 with the bgm BigBox. Seems to be fun:

Conclusion

Nice to see in the diagrams: ours 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.
