The
latest production of Vespa PX125/150 scooters now come supplied with a
CDI with a waterproof multi plug, and although functional, these CDI
units now have a rev limiter at approximately 7000RPM.
This rev limiter will introduce problems if you wish to fit a bigger
cylinder kit or exhaust system. This will make any performance
modifications pointless as most cylinder kits and exhaust systems will
require a higher RPM than 7000 to reach full potential.
The new Readspeed "Zeus" CDI has been designed for this late ignition
system and removes the Rev Limiter allowing you to further tune the
vehicle from standard format to higher performance.
Priced at £79.99p the Readspeed "Zeus" CDI is a cost effective solution to this problem.
