BMW K1300R

The BMW K1300R is a naked motorcycle made by BMW. The engine was subtly modified by British company Ricardo plc.  It has an exhaust butterfly flap to boost torque and improve exhaust note. The K1300R features BMW's optional ESA-II electronic suspension adjustment. The bike also has a conventional indicator switch instead of the usual BMW three button configurations.

The K1300R is considered a muscle bike, a slang term for naked or standard motorcycles that put an emphasis on high power output and fast acceleration. Its close gearing and exceptionally broad power delivery provide the drive output power necessary to accelerate quickly, while its long wheelbase and low and canted mounted engine help the motorcycle plant the power without unintentional power wheelies. In tests carried out by Bike Magazine in the UK, its 2.81 second 0–100 km/h (0–62 mph) time made it the fastest accelerating naked motorcycle.
