How does engine size affect motorbike insurance?


As with cars, you’ll typically find that the more powerful your motorbike is, the greater the cost of your insurance will be. When looking at buying a motorbike, you’ll probably encounter a measurement known as “cc” which stands for cubic centimetres and directly relates to the size of the motorbike engine. This means the higher the cc number, the more powerful the motorbike will be.

Insurers typically see powerful motorbikes as more of a risk than ones with a smaller engine size, usually because they’re perceived as more likely to be involved in an accident. That means you’ll usually find that as you move up the cc brackets, the more it’ll cost to insure your motorbike due to the higher speeds the bike can reach. For example, 250cc motorbike insurance and 1000cc motorbike insurance costs will differ greatly as their overall power is different.

For example, if you started off with a 50cc motorbike and modified or changed this to an engine size of 250cc, motorbike insurance costs will be significantly different as the power of your bike has increased.
