JetPrime Short-Stroke Throttle Grip for Aprilia RS 660 (2020-2026) – JP ACC 109

Shaped by the demands of WSBK and WSSP 600 competition, the JetPrime JP ACC 109 short-stroke throttle grip brings a lineage of professional motorsport engineering to the Aprilia RS 660. Machined from solid billet aluminium, it distils that traditional cable-throttle feel into a modern, high-precision component that looks as purposeful as it performs.

Key Features

• 60-degree rotation angle replicates the direct, organic response of a classic cable throttle — trusted by top-tier Superbike and Supersport 600 race teams
• CNC-machined from solid billet for exceptional dimensional accuracy and long-term durability under hard use
• Developed in direct collaboration with WSBK and WSSP 600 factory and satellite squads
• Designed to accept JetPrime handlebar switch kits, enabling a clean, integrated cockpit build
• Purpose-built for riders who demand precise throttle authority on track and road alike

Heritage Meets Precision Manufacture

JetPrime's reputation was forged at the very top of production-based racing, and the JP ACC 109 carries that heritage in every machined contour. The 60-degree throw is a deliberate engineering choice: short enough to deliver instant throttle response out of tight chicanes, yet familiar enough to retain the analogue connection that experienced riders prize. Unlike cast or stamped alternatives, each unit is milled from a single billet, ensuring zero play and a surface finish that holds up to both track abuse and daily road use.

Precision Control for Road and Track

For Aprilia RS 660 riders who run the bike in both road and circuit environments, the short-stroke action transforms cornering exits. Less wrist rotation means the hand stays more relaxed through long track sessions, reducing fatigue without sacrificing feel. The fitment for JetPrime's own switch assemblies also means that if you are building a fully bespoke cockpit — clip-ons, bar-end mirrors, integrated controls — the JP ACC 109 sits at its centre as the logical foundation piece.
