At DMG Motorsports, we present the Yoshimura R-77M Premium Muffler Repack Kit (SKU: 960-9975, MPN: REPACK-R77M-ADV) — the factory-correct refresh kit designed to bring your Yoshimura R-77M muffler back to peak condition. Over time, exhaust packing material breaks down from heat and use, robbing your bike of the power and sound your Yoshimura system was built to deliver. This premium repack kit contains everything needed to restore your muffler to like-new performance, and because it's fitted specifically for the R-77M, you get a precise, hassle-free repack every time.

Features:

• Genuine Yoshimura premium packing material engineered specifically for R-77M mufflers
• Complete kit includes rivets, rivet band, R-77 name badge, and detailed repack instructions
• Restores lost power and improves exhaust sound by allowing freer airflow from the engine once dirty, worn packing is replaced
• Designed to fit R-77M mufflers only — not compatible with standard R-77 units
• Recommended repack interval of every 7,000–10,000 miles to keep your exhaust performing as designed
• Built for motorcycles in standard, as-delivered factory configuration
• Backed by Yoshimura's engineering standards for consistent, reliable exhaust performance
