First thing to check is tyre pressure. It's also the one thing most likely to change over the course of a few hours.

Can you expand a bit on the symptoms too? Speed you're travelling, whether the bars are aggressively turning to the left at low speed or if the bike is just wandering to the left at normal road speeds.. That sort of thing.

That was the first thing a thought of was the Tyre pressure but the seem fine the rock solid and it a was traveling about 30 mph. The bars never suddenly turned to the left they just gradually started to veering to the left. after it happened i just rode home shitting my self lol lol and put it in the shed and its been there since. Im going to get it out tomorrow and have a look at it see if there anything obvious up with it not that a now what am looking at or anything a mate said he will have a look at it for me.

Give everything on the front end a good bounce, shake and twist. See if anything moves that shouldn't. Also check the rear tyre pressure.

What's weird is that things don't usually just 'go' like that. Bearings wear, frames get bent, forks twist, sure, but bearings will grumble and get notchy first, usually, and you'd know if you'd had the sort of incident that leads to bent metal.

The wheels may be slightly out of alignment, you can check that with a length of string (there are YouTube vids that help) but is there any chance you were just on a horribly cambered road surface at the time the issue arose? 125 tyres, especially the horrible hard compounds they tend to fit at the factory nowadays, can track quite significantly on bad roads.

Isn't it possible, you just went across a longitudinal unevenness on the road? Sometimes lorries and other heavy vehicles in general imprint straight lines (rails) into the tar, which affects cars and esp. motorcycles. It forces the wheels of the bike to get inside or outside the line (rail). The most deep lines (rails) tend to be in the intersections with traffic lights, as when in summer the heat gets up, the tar gets more soft/formable and standing vehicles have more time to feck up the road.

No it deferentially wasn't the road because it started veering to the right a little on the way home. and its weird when a take a roundabout it sort of pulls out a bit as if it cant get round if you no what a mean. i just put it down to bad handling an just getting used to the bike at first till that happend on the road.

Check the brakes are not dragging. When I had issues with the Tokico 6 pots, some of the pots were returning a bit slower than the rest, causing it randomly dragging, which felt like a force pulling me out off the corner. Which is what happens when you apply the front brake mid corner, the bike has tendency to straighten up.
