If you own or are considering buying a 1979 Lambretta Gp, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects.
