Tens of thousands of highly polished chopper motorbikes with riders and pillions converging at Port Grimaud in the south of France for the 2017 HOG Eurofest. Several thousand bikes participated in the parade through the streets of Cogolin, St. Tropez and finishing at the festival site on the beach at Port Grimaud for a rock concert. Traffic jams for the cars and mobile phone networks overloaded... Big noisy Harleys predominated but not a few other chopper bikes from other makers, customised more or less within the limits of being street-legal. And even Harley do a sports bike.
