Assuming March onwards is the worst time to change bikes as dealers have plenty of punters walking in the doors, when are they at there most receptive to lower margins? Could it be November to January ?
End of February or end of August, so that dealers can sell bikes before the new registrations come out
Also if you are buying new there tends to be manufacturers offers around this time, especially if a new model might coming out
Change for a mint low miles used bike a month or so after the new plate, when the new bikes are all sold and the trade in PCPs -that no hardly rode- are wall to wall? You save 20% VAT plus the depreciation, maybe you can buy two...
Dealer margins are quite tight. As said, not much in it. If there was everyone would be steaming in at the same time. Sales volumes might be down in autumn and up in spring, but mega deals are a unicorn. Quite often if I’m on the hunt for a new TV, bike, car, lawnmower or whatever, I time it for when there’s an all singing and dancing latest model/revision released. You can generally get a decent deal on the brand new ‘old’ generation. For example I’ve just a bought a new mirrorless camera. As soon as Canon announced the new holy grail, hey presto the one I wanted shed £1.5k.
