Silencer Exhaust RX/SX 125 - XTM/XSM 125 4T Arrow Thunder Approved

Exhaust muffler Arrow Thunder 52509 for motorcycle Aprilia RX - SX 125 4T - Malaguti XTM - XSM 125 4T - UM DSR 125 4T. Off-road design is heading towards a bike which is year by year lighter, compact and stiff. This caused Arrow to develop a new line of systems to match the needs of off-road riders. Arrow most important features like lightness, performances, reliability are now combined to the experience coming from years and years of races and “dirt” work on “dirt bikes” (work leading Arrow to a real dominance in the MX World Championships of the last ten years). This background led to the Off-Road Thunder exhauts. The diamond shape, a major distinguishing feature of Arrow brand, a real “trade mark”, ensure the best balance between inner volume and external dimensions, matched directly to the rear endcap, designed to fulfill the requirements stated in worldwide racing rules. TIG welding, top level materials (silencer canisters are available in titanium or aluminium) and a focus to details contribute to place Off-Road Thunder exhausts on the top level among “dirt” systems.

Arrow EU approved exhausts have rear cap removable (Db-killer) and are supplied with certificate of approval to be attached to the vehicle registration certificate. Removal of Db-killer transforms the silencer from homologated to racing, generating a performance improvement, but lost the approval compliance. The assembly does not require changes to the carburation, mappings or the use of additional units.
