Yoshimura · Alpha T
The Yoshimura ALPHA T (Taper) Premium Muffler Repack Kit is a replacement service parts solution designed to refresh muffler packing at the intervals Yoshimura recommends for Road exhaust systems. Keeping the packing material in good condition helps the exhaust continue operating as intended, supporting proper airflow and maintaining exhaust tone over time.
This kit is intended for the applications listed in the fitment table, including select models from Aprilia, BMW, Honda, Kawasaki, KTM, Suzuki, Triumph, and Yamaha. It includes the key service items needed for a straightforward repack, along with repack instructions, so the muffler can be returned to its designed performance and sound characteristics after miles of use.
Performance
Yoshimura notes that Road exhaust systems should be repacked every 7,000 - 10,000 miles. Following that interval helps prevent worn or dirty packing from restricting airflow, which can lead to a loss of power and a degradation of sound.
Materials
This kit includes premium packing material intended to restore freer airflow through the muffler after the original packing has become dirty or spent. Repacking at the recommended time helps bring back the exhaust sound characteristics the system was designed to deliver.
Included
Along with packing material, the kit includes rivets, a rivet band, an Alpha T name badge, and repack instructions. These included components support a proper service refresh so the muffler can be reassembled cleanly after the repack is completed.
Performance
Over time, muffler packing becomes dirty and less effective. Yoshimura explains that dirty packing can restrict airflow from the motor, which results in a loss of power and degradation of sound. Repacking the muffler at the suggested service intervals allows for freer airflow from the motor, which restores lost power and improves the exhaust sound.
Fitment
The ALPHA T (Taper) Premium Muffler Repack Kit is intended for specific applications across multiple makes and models; reference the fitment table on the page to confirm compatibility with a particular motorcycle and year range. An installation PDF is provided on the product page to support the repack process using the included repack instructions.
