Not necessarily nath. It can just can just come loose.
Yeah real easy mate. But like nath said if uou've been riding hard with it loose i'd be tempted to check the bearings.
Literally remove front headlight. Indicators. Clocks. Handlebars. Unscrew the nut on top of the yokes. Remove yokes. Unscrew the two locking nuts. Take the dust cap off. Examine bearings. If they're ok then put it all back together. Except with the lockin nuts tighten it up as much as you can with the c spanner. I've been told to tighten them up until you can't move the bara. Then crack it off half a turn. Should be nice and tight.
