Exhaust BGM ORIGINAL BGM PRO BigBox TOURING V2 (BBT2) Vespa T5 125cc (VNX5T)

This BGM BigBox is designed as a replacement for the excellent exhaust system of the Vespa PX special model T5. The T5 engine, designed by Morini, has some peculiarities due to its adapted high-performance 125cc motorcycle cylinder. Consequently, the T5 engine reacts very strongly to replacing the exhaust system. The BGM BigBox for the T5 is based on the standard exhaust system to maintain torque at low and medium engine speeds at a similarly high level as the standard exhaust. Depending on the setup, it may rev a little higher.

The BigBox therefore harmonizes with the original engine as well as with Polini 152 or Malossi 172 tuning cylinders. On modified engines, the larger volume of the BigBox Touring provides a significantly better torque and power curve than the original exhaust.
