changed my front tyre a while back on my ducati 748. derestricted it at the same time.
when i reach 160+km/h (hadn't been able to do before derestriction) the front end shakes like crazy. i read a few articles that describe that the bike vibrates and some people find it uncomfortable at speed but i feel as though this is more than a vibration, rather violent shaking.
i first found the problem on a high speed bend. needless to say i had a little moment. but i rode on.
could it be something as simple as an impropperly balanced wheel or does anyone know of other possible causes?
