RMS, Italy, is a prolific manufacturer of OEM quality aftermarket parts for many scooter brands, including Vespa Vintage and Vespa Modern parts. Their catalogue is extensive, with equipment made for even the most vintage models. Apart from OEM quality parts, RMS designs tuning parts so you can boost your moped / scooter engine.

This is a RMS Cylinder Kit 125cc Vespa PK 125cc; The 55mm bore will not increase displacement, but as it is a "Sport" cylinder, you will notice a nice increase in torque and wider power band. More power means you have to adjust the rest of your set-up a bit - we definitely recommend a reinforced crankshaft capable of dealing with the increase in power.
