Slow Riding takes a whole new meaning when combined with turning a heavy motorcycle.
For handling a heavy motorcycle such as a Harley Davidson Fat Boy or an Indian Dark Horse model at slow speed successfully, you need to use all the 3 controls in a coordinated fashion: clutch lever, rear brake pedal and accelerator (as needed).
