Pro Circuit Yamaha YZ125 YZ125X RV Works Pipe & Ti-2 Silencer Bundle — Champ Spec — PY05125-RV, 1131412K-RV

Pro Circuit Ryan Villopoto Spec Bundle — Championship Performance, Bolt on the Multi-Time Champ's Setup

Stop guessing which exhaust combination provides the best "snap" for your small-bore engine. This Pro Circuit bundle pairs the Ryan Villopoto (RV) Spec Works Pipe with the Ti-2 Carbon/Kevlar Silencer to solve the common low-end bog found on stock setups. Developed specifically for RV when he made his iconic return to the YZ125, this high-performance package is tuned for tighter, softer tracks where acceleration out of corners is the difference between leading and following.

The RV Works Pipe is crafted from stamped AKDQ high-quality carbon steel with hand-welded and pounded seams for Factory Quality flow. By pairing it with the Ti-2 Silencer—which features a lightweight Aramid fiber canister and titanium tubing—you significantly reduce weight while gaining a tailored powerband that is stronger on the bottom-to-middle range than standard systems.

• Pro Circuit RV Works Pipe (PY05125-RV): Raw oiled metal finish designed specifically for increased bottom-to-mid torque.
• Pro Circuit Ti-2 RV Silencer (1131412K-RV): Ultra-lightweight Carbon/Kevlar and Titanium construction for a professional factory look and sound.

• Stronger pull off the start and out of corners on tight or soft terrain.
• Hand-welded and pounded seams provide precision internal exhaust scavenging.
• Ti-2 silencer utilizes Aramid fiber and Titanium end-caps to minimize weight.
• Reinforced mounting brackets and stinger for maximum durability under race conditions.
• Factory Quality CNC-machined aluminum mounting brackets for a perfect, secure fit.

Moto-House MX Pro Tip:

This "Champ Spec" setup is a raw metal system, meaning it needs a little maintenance to keep that factory shine. After every wash, we recommend applying a light mist of WD-40 to the pipe while it is still warm to create a protective barrier against rust and help the metal develop a beautiful blue-tinted "works" finish over time.
