vespa PX125 RZ MK1 RH ORIGINAL Stainless Polished

RZ Mk1 RH “Top Power” Stainless Steel Polished
This Exhaust represents the most powerful expansion chamber exhaust system that we have ever produced for the VESPA PX range. This righthand exit exhaust system can get an extra couple of horse power from motors that leaves lefthand exit systems behind. Very strong powerban with a strong Low rev range. The (more) flexible spring connections between the exhaust manifold, expansion chamber and silencer unit help to absorb unwanted knocks and consequent damage to the exhaust system. Although this exhaust can be mounted to older VESPA models such as SPRINT or RALLY etc., it is made complicated by the lower side panel design and so requires a little modification during fitting and lots of patience!

The impressively peaky performance that the “RZ Mark One” offers, demands a lot of control and rider involvement. Maximum power delivery occurs between 5000 and 6000 rpm. The on/off switch performance can be stressful around town but an absolutely ideal power band for road and track. With the more moderately tuned, road going motor set ups the fitting of a shorter 4th gear has proved useful.
