Posted August 7, 20177 yr Hey, Just wanted to ask you guys at what speed should I go for longer distances (like 50 miles/ 80 kilometers) on my YAMAHA R125Â so it doesn't overheat or break or stop working and etc... In my country max speed is like 130kmh/80mph and thats like max yamaha r125 speed so how fast should I go for long distances? -Noah
