Suzuki Savage and S40 Bobber 1986-Present. The Thumper has arrived!!! Lightweight, dependable, cheap, clean look, a blast to ride, excellent mileage, unusual neat sound and a really cool little bobber. That huge single cylinder has the same thump as the old BSA’s from the 50’s and 60’s. The low end torque make these the perfect bobber for the smaller riders.
