The engine cases are a match with the Africa Twin’s, and the Unicam engine head is distinct from the DOHC engines employed on the existing Rebel 500 and 300. The front view (pictured below) shows an engine, and fuel tank that are noticeably wider than the svelte Rebel 500.

This allows the radiator to provide a bit of protection to the exhaust sensors while also allowing easy access to them. The sensors are also protected …read more
