The abbreviation DRT stands for Denis Racing Team. Denis Innocente has found its way into scooter parts production via the Italian acceleration racing scene. With a background of more than twenty years in motorsport, he mainly manufactures transmission and clutch parts for the Vespa today. The Italian scene swears by the DRT parts. Thanks to the various primary and power wheels, you now have unprecedented freedom in grading your transmission. So you can build yourself a gearbox with your desired gradations. From the closely stepped racing gearbox to the tourer gearbox for the shift muffle. For lower mass acceleration, the DRT gears are lighter.
