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 entire 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 kilometers 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 great alternative not only for these classic cars. Choose between Big Box Touring or Big Box Sports, depending on the engine concept and characteristics.
