MILWAUKEE-EIGHT™ VVT 121 POWERTRAIN
The highest displacement powertrain ever to be factory-installed on a Harley-Davidson Touring motorcycle, the Milwaukee-Eight VVT 121 features liquid-cooled cylinder heads, variable valve timing (VVT) and a new intake tract. The increased displacement produces more power and torque than the Milwaukee-Eight 117 engine, while VVT broadens the overall powerband and improves fuel economy.
