Aprilia RSV4 2025 GP-R4R exhaust

The R4R Exhaust: a bold choice for riders seeking something unique. Designed with a striking conical shape, the R4R delivers exceptional sound and performance while standing out with its distinctive style.

Handcrafted in the UK with premium materials, the R4R is available in two sleek finishes: Brushed Titanium for a classic, refined look, or Ceramic Black for a modern, aggressive edge. Its lightweight design and precision engineering ensure optimal gas flow and enhanced performance.

Each R4R comes with a removable baffle, giving you the flexibility to adjust the sound to your preference. Combining innovative design, top-quality craftsmanship, and standout aesthetics, the R4R is perfect for those who want their bike to look—and sound—like nothing else on the road.
