GRT Velocity Stacks for Aprilia RS 660 and Tuono 660 (2021/2024 – USA 2025)
Optimize your Aprilia RS 660 and Tuono 660 with velocity stacks for an unparalleled ride!
The RS 660 and Tuono 660 velocity stacks are designed to significantly improve torque and engine power, making your riding experience even more performant. Made from 6082 T6 aluminum alloy, these velocity stacks are the result of numerous tests on 3D-printed prototypes aimed at optimizing length and conicity for maximum efficiency. Thanks to these improvements, the engine responds better across the entire power band, reducing torque drop at mid-range and improving drivability. Additionally, the intake sound becomes deeper and more pronounced, adding a sporty touch to your bike.
The kit works well on OEM RS 660 and Tuono 660 maps with the stock exhaust (the first of the three attached charts), but great results can be achieved with a Race map when used with a decat exhaust (see the other charts).

The RS 660 and Tuono 660 are among the few bikes that show a real gain from using a racing air filter. Therefore, I recommend using the Sprint Filter for its durability, easy cleaning, and the fact that it works dry without needing lubrication:
