The 52-year-old British Citizen, who has not been named for legal reasons, is said to have hit the 42-year-old head-on with his car yesterday.
The Man was said to be attempting to perform a U-turn in the middle of the road and struck the motorcyclist.
The incident occurred around 3pm on Thursday outside a fire station near the village of Prosilio on the Kalamata-Areopolis road that runs across the southern coast of the country.
Local reports said the motorcyclist, a father-of-two, was killed instantly.
The father-of-two was a driver at an intercity bus firm in Messina, a region in the southwestern part of Greece's Peloponnese region.
It is believed he was returning home south to Kalamata on his motorcycle after work.
Western Mani police said the collision happened some 17 miles (around 27 kilometers) along the long stretch of road.
Police said the driver, heading towards Areopoli, further down the coast, then entered the opposite flow of traffic.
The municipality's Western Mani authorities confirmed that the 52-year-old British citizen was arrested.
Police said they would continue to investigate the fatal incident.
