The Bolt keeps its classic bobber look, while Yamaha claims the Bolt R-spec will be the "sportier" version. With that said, both bikes retain their 942cc 60-degree V-twin engine, sharing everything from frame, suspension, wheelbase, brakes, seat height, rake and trail; all unchanged from the previous year. Each bike gets a new flangeless fuel tank for 2017, cleaning up the transition edge from tank to frame. Additionally, the fuel capacity of both bikes gets a bump up by 0.32 gallons, increasing range to an estimated 173 miles. To further clean up the aesthetic of both bikes, the wiring has been tucked more neatly away with wire guides.
