The Arrow Off-Road Thunder Dark aluminum exhaust with carbon end cap (code 52510AKN) is an ECE Euro 5 approved slip-on exhaust specifically designed for Aprilia RX 125 and SX 125 (2021-2024). The Off-Road Thunder line is the result of Arrow's decades of experience in global off-road racing, featuring a diamond-shaped design that optimizes the relationship between internal volume and external dimensions, ensuring lightness, compactness, and superior performance.
