got a piagio x7 on a ten plate , there is a lot of movement at the rear wheel sideways rides as if the tyres are soft but there not any ideas as to were to start looking

Is the rear axle bolt tight? Or has the rear wheel been refitted minus a spacer after a tyre change? Had both above happen to me.

Try the fowlers parts site for exploded diagrams of the rear wheel, check spacers etc...

If you are describing the feel when riding rather than actual play at the wheel the it could be a symptom of a worn tyre with a flattened centre. Scooter tyres can square off leaving the centre very thin and this can lead to frightening squirming over road repairs and grooved concrete surfaces.

check the engine mounts

my old runner had this problem back wheel moved about three inches from one side to the other (inch and a half each way) and was found to be the mounts that joint the swing arm and engine to the front

Another vote for engine mounts here

thanks every one tyre is good , its actual movement from side to side at the rear wheel will check fowlers site
if I take the seat base out and shake the rear wheel the engine can be seen moving a fair bit
will dig deeper during the week and report back

Videos are available on the tube as to how to change the engine mounts if you have not done it before.

wheel bearing . or spacers like others have said or even ill fitted rear wheel always check simple things first.

You haven't said exactly where the play is visible.

If it's just the wheel, then wheel bearings, tightness of the wheel nut - as others have said - or the final drive output shaft bearings want looking at. The first two are easy; the latter less so.

If the engine is moving side-to-side with the wheel then the engine hanger bushes are knackered. I don't know about your scooter, but this is an arse of a job on the Helix.

Either way, I wouldn't be riding it again until you've got it fixed. Good luck!
