Slip-on rear silencer Aprilia RX/SX 125 from year 25 (Euro5+), without EG-BE

The Arrow Thunder rear silencer gives your Aprilia the sporty look and rich sound it deserves.
The matt black aluminum body with stainless steel end cap impresses with its high-quality workmanship, low weight and long service life - typical Arrow.

The exhaust is perfectly matched to the standard manifold of the new Euro 5+ models and noticeably improves the engine's response.
The result: a throaty sound, a sporty look and less weight - all legal thanks to EU homologation (E number).
An ideal upgrade for anyone who wants to upgrade their 125 visually and technically.
