The Street Bob in its 2025 India spec is powered by a 1,923 cc V-twin engine (Milwaukee-Eight 117 Classic) with an electronic sequential port fuel-injection system.

It develops about 91 hp (≈68 kW) at 5,020 rpm and 156 Nm of torque at 2,750 rpm. This engine gives it substantial low-end punch and cruiser character — ideal for highway cruising, though the bulk and weight remain considerable.
