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.
✓ Strengths
- ECE Euro 5 approved – legal for road use with db-killer installed
- Dark aluminum body – much lighter than the original steel, better heat dissipation
- Carbon fiber rear end cap – premium design, durable, and ultralight
- Stainless steel silencer internals – durability and corrosion resistance
- Weight 2.43 kg – significant weight reduction compared to the stock exhaust
- Removable db-killer – for track or closed-circuit use
- Arrow diamond design – optimized shape for the best volume/space balance
- TIG welding – high-quality manufacturing with premium materials
- Slip-on mounting – installs directly onto the original header
