best thing to do is make sure the bike's clean and well maintained.
Always take it to the same MOT centre.
talk to the Operator, tell him you'll see him next year!
My MOT takes 5 mins, brakes, lamps, swing arm, horn, tyres. here's to another 12 months.
He told me he's sick of the scooter brigade with dirty unloved hacks, he goes to town on them to make sure they are safe for the litle darlings!!
