RS660 Season 2026

Aprilia RS660, Track Days, Data Acquisition, Suspension Setup

For the past five years, I’ve worked with motorcycle racers on data acquisition, lap simulation, and suspension setup. Last season, I decided to explore the other side of the equation—riding on track myself—to validate my approach to bike setup and coaching.

To do this, I chose the Aprilia RS 660—a platform I consider one of the most interesting combinations of engine and chassis performance in the middleweight class. With its short wheelbase, the bike offers strong agility and fast direction changes, while its advanced electronics provide a solid foundation for data integration and analysis.

This page provides a brief overview of the bike and its current setup as my track-focused development platform for the 2025 and 2026 seasons.
