In Indonesia the YZF-R15 is known as the Yamaha V ixion. The specs are pretty much the same except without the front fairing giving it a more street fighter look. My bike is still standard but planning to change the tires for more stability. Can anyone suggest a good tire measurement that´s fitting without having to change anything other than the tires or wheels? I´m still a major newbie to bikes and need as much info as i can get.
