Racing Exhaust RZ Mark One

for Vespa P80-150X/PX80-150 E
/Lusso/`98/MY/Cosa 1
steel, black, stainless steel
silencer, right hand,
fits wide tyre

FOR RACE USE ONLY

The “RZ Mark One” represents the most powerful expansion chamber exhaust system that the pipe-guru Jim Lomas has ever produced for the VESPA PX range. This righthand exit exhaust system can tickle an extra couple of horses from motors that leaves lefthand exit systems behind (you). But beware of the sudden avalanche of power delivery! The silencers location, protruding from underneath the gearbox ensures a guaranteed eye catching extra to any PX motor setup. 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 quarter mile sprints :-). , the ideal playground for fun with this pipe! With the more moderately tuned, road going motor set ups the fitting of a shorter 4th gear has proved useful. If your set up includes a professionally ported MALOSSI 210cc,a high end Low Primary Compression crankshaft, a MMW reed valve manifold assembly and a decent carburettor of at least 32mm diameter ,the RZ pipe can easily cope with taller transmission ratios to deliver a higher end speed. The "RZ Mark One" is also ideal in combination with the POLINI 208cc,with it's delivery of power lower in the rev.range and more moderate port timings, so avoiding a too rapid rev increase and over revving.

JL Guarantee: Included with every SIP-Performance expansion chamber system is an automatic 3-years warranty from date of purchase for all original purchasers, if your exhaust splits open at any time during normal use (apart from grinding it along the curb) it will be repaired or replaced

Searching for a cheaper alternative, take the RZ Mark Two. LTH are now producing its successor at an unbelievably low-price. Compared to the first version, there are only minimal changes and updates to its design. The silencer of the RZ Mark Two can be identified by the following stamps on its side: RZ *MARK TWO*, BS AU 193 A 1990 T2.

Conclusion: Often copied but never equalled the RZ is a high quality, maximum power expansion chamber. Not for the faint hearted.

 

Competition Expansion Chamber/ Steel or stainless steel construction, black painted finish/ stainless steel silencer/ right hand exit

Stainless steel/steel, black painted, stainless steel silencer, right hand, springed manifold/exhaust connection assembly

This exhaust pipe allows the use of larger tyre sizes, a spare wheel and also the main stand of your VESPA PX. carburettor jetting and ignition timing should be checked and/or altered as necessary.

 

SIP-TIP: In combination with 139-177cc kits a 24mm SI carburettor and a taller transmission ratio are necessary. With 200cc cylindered motor set ups a lager jetting is mandatory, we recommend a reinforced clutch and a racing/ long stroke crankshaft. With a POLINI or MALOSSI, 30mm or lager carburettor, MMW manifold, a taller transmission and a VESPATRONIC you will have all the fun, ahead of the pack!
