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

BGM BigBox Touring for Vespa T5

This BGM BigBox is designed as a replacement for the sensational 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. Thus 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 system to keep the torque in the low and medium speed range at a similar high level as the standard exhaust. Depending on the setup, it can turn a little bit more.

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