Racing Stage 2 Kit for RS 660 & Tuono 660 E5+ (2025 / USA 2026) – UpMap + GRT Velocity Stacks
Upgrade your Aprilia RS 660 or Tuono 660 E5+ with this complete Stage 2 Racing Kit, engineered specifically for the 2025 E5+ platform (USA 2026 models). This plug-and-play package combines the advanced UpMap T800+ ECU tuner with precision-developed GRT velocity stacks, delivering stronger mid-to-high RPM performance, sharper throttle response, and smoother power delivery—while maintaining reliability for both road-focused sport riding and track use.
Overview
Built on the proven success of previous Stage 2 kits, this updated version is tailored exclusively for the latest E5+ generation. By integrating optimised intake components with dedicated ECU mapping from Gabro Racing Team, this kit enhances airflow efficiency from approximately 8000 rpm to redline.
The result is a more responsive, more powerful engine character—featuring improved acceleration, a stronger top-end pull, and a deeper, sportier intake sound. Best of all, installation requires no permanent modifications to the airbox or wiring.
