For every debate that could be made in favour of buying a new car, in nearly every scenario, a case can also be made in favour of buying a second-hand one. That is even more so when it comes to motorcycles.
Places to search online include WeBuyCars, Facebook Marketplace and Gumtree. At the time of writing, the former had 211 motorcycles listed, Gumtree had 2 800 (including scooters) and Facebook, quite possibly, had more than the two combined. Autotrader has more than 3 000 bikes listed for sale.
