Yoshimura · R-77
The Yoshimura R-77 Premium Muffler Repack Kit is a replacement service part designed to refresh select Yoshimura Road exhaust systems. Yoshimura states these systems should be repacked every 7,000 - 10,000 miles to help the exhaust continue performing as intended.
Old, dirty packing can restrict airflow from the motor, which Yoshimura notes may lead to lost power and a decline in sound quality. Repacking helps return freer airflow, restoring lost power and improving exhaust tone. This kit is listed for a wide range of fitments including BMW, Honda, Husqvarna, Kawasaki, KTM, Suzuki, and Yamaha models shown in the fitment table below.
Materials
This kit includes premium packing material along with the supporting hardware and components needed to service the muffler: rivets, rivet bands, and an R-77 name badge. It’s a straightforward way to replace wear items during routine maintenance without guessing which small parts are required.
Performance
Yoshimura recommends repacking at 7,000 - 10,000 mile intervals so the exhaust continues to function as designed. Fresh packing helps reduce airflow restriction caused by dirty material, supporting freer exhaust flow and helping restore the power and sound that can fade over time.
Installation
Repacking is easier to tackle with clear guidance. This kit comes with repack instructions to help ensure the new packing and included components are installed correctly, supporting consistent results and helping the muffler return to its intended sound and operating characteristics.
Performance
Muffler packing is a wear item, and Yoshimura notes that as packing becomes dirty it can restrict airflow from the motor. That restriction can contribute to a loss of power and a degradation of sound. Servicing the muffler with new packing at the recommended interval helps bring airflow back to a freer state, which Yoshimura says restores lost power and improves exhaust sound.
Included
The R-77 Premium Muffler Repack Kit is assembled to cover key consumables and finishing details used during service. Along with premium packing material, it includes rivets and rivet bands for reassembly, plus an R-77 name badge. Repack instructions are also included to support an orderly, repeatable maintenance process.
Fitment
This repack kit is specified for a broad list of applications across BMW, Honda, Husqvarna, Kawasaki, KTM, Suzuki, and Yamaha models, with model years shown in the fitment table on the page. An installation PDF is also provided on the product page to support the repacking process and help confirm the correct approach for servicing an R-77 muffler.
