MIVV has announced the next-generation HR-1 slip-on for Softail models. It is scheduled to be unveiled at the next EICMA in Milan and will expand the lineup for models equipped with the Milwaukee-Eight 117 engine.
MIVV has developed a new HR-1 slip-on muffler for Softail models. Designed to strengthen its presence in the Harley-Davidson market, it is intended for the Street Bob, Low Rider S/ST and Heritage Classic.
The HR-1 is described as fully compatible with current Softail models equipped with the Milwaukee-Eight 117 engine. It can be installed as a direct replacement for the original silencer without requiring modifications. It is positioned as a direct-replacement solution approved for road use.
The muffler is made entirely of stainless steel and is available in two appearance options: a polished finish and a black ceramic coating. In 2026, MIVV also introduced the touring-oriented HR-1 series of dual slip-ons combined with headers, which had previously made its world debut at EICMA.
