Auspuff Vespa PK 50 bgm PRO BigBox TOURING

NEW: Exhaust bgm PRO BigBox TOURING for Vespa PK50 & PK125

Quite secretly a new racing exhaust for Vespa PK has crept into our shop. Today we present the new Vespa PK exhaust from bgm PRO.

Vespa PK Rennauspuff - bgm PRO BigBox Vespa PK | HANDMADE in EUROPE

We have two versions:

  1. for Vespa PK50 & PK80 | BGM1050PK
    Exhaust -BGM PRO BigBox TOURING PK- Vespa PK50, PK80 (S/XL/XL2/HP/SS/Lusso)
  2. for Vespa PK125 & PK75 | BGM1125PK
    Exhaust -BGM PRO BigBox TOURING PK- Vespa PK125 (S/XL/XL2/ETS), Motovespa PK75 (S/XL/Junior)

The history of this exhaust system lies in the fact that there were no original Piaggio exhaust systems for the PK 50 models. During the development of a new exhaust we recognized the potential and were able to develop a sport exhaust with original optics, low noise level and a significant increase in performance. The bgm PRO quality exhaust is now handmade in Europe and is available immediately: bgm PRO BigBox TOURING Vespa PK

Vespa PK exhaust with more power, discreet look & low noise

The bgm PRO exhaust in the TOURING version thus provides the discreet look and acoustics of an original Vespa exhaust, combined with a sports exhaust characteristic with high torque and wide power band. This system was originally designed as a replacement for the original Piaggio exhaust systems, which are no longer available. In the meantime we have developed it to a full-fledged, modern sport exhaust system.

We attached great importance to a good performance with a discreet noise level as well as a good fit.

  • Significantly more power
  • Quiet racing exhaust
  • Good fit
  • Original optics
  • High and early torque
  • Wide speed range
  • More final speed
  • Very unobtrusive
  • Fits without modifications
  • Handmade in Europe

The bgm PRO Sport TOURING harmonizes very well with a standard engine as well as with the classic tuning cylinders like the

  • Polini 75-112,
  • DR75-102 or
  • Malossi 75-112
  • Polini 133

Easy mounting

The relatively far down split manifold allows a quick disassembly of the exhaust body without having to loosen the manifold on the cylinder. The connection is secured by tension springs in a stable but quickly detachable way.

For safety reasons we recommend to start with 2-4 numbers more than a standard exhaust.

SCOPE OF DELIVERY

  • Exhaust body
  • Exhaust manifold
  • Exhaust Springs
  • Cylinder/ manifold gasket

Vespa PK Exhaust TIP:

  1. Adjust spraying, see above.
  2. Some heat-resistant sealing compound (see accessories for the exhaust) between manifold and exhaust body keeps this area permanently clean.

POLINI ROAD BOX Vespa PX now available again

The Polini Road Box exhaust is now available again for small and big engines:

This Poini exhaust for Vespa is a very good alternative to the old SIP Road. The Polini outperforms the SIP Road over the whole rev band, both in power and torque. The early and high torque application makes the Polini Box the ideal touring companion. The well-thought-out design of the exhaust system makes it possible to maintain the low and pleasant noise level of the system permanently.

Of course we tested the exhaust ourselves and drove many kilometres with it. The quality and fit is good, even the exhaust paint on the manifold lasts longer than average. Harmonizes very well with the BGM177 cylinder.

TIP: Choose the carburetor spraying about 2-3 sizes bigger than a SIP Road

JUST FOR VESPA PX?

The exhaust was designed explicitly for the Vespa PX models. On older vehicles, which were built before the PX series, it is possible that the stop plate of the main stand touches the manifold. From our experience they only touched the angle plate of the main stand at Vespa Sprint, Rally and Co.

bgm BigBox – a good choice!

Our bgm BigBox fits of course on PX and the Touring without problems also on Vespa Rally, Sprint & Co. and is often a super alternative not only for these oldtimers. Choose between BigBox Touring or BigBox Sport, depending on the engine concept and characteristics.
