How motorbike insurance is calculated


When getting cover for your bike, it helps to understand how insurers set their prices so you can help reduce the cost of your policy.


Generally speaking, the amount an insurance company charges is a reflection of: 

  • how likely you - as a biker - are to make a claim

  • how expensive that claim is likely to be

Some of the factors involved you can’t do much about, such as your age.

But there are others – say, the type of bike you ride, and how much you use it – that you do have some sway over.

Some insurers may put more weight on certain factors over others, so it’s worth shopping around for policies and find one that suits your wallet.

These are some of the more common factors that insurers look at:

Your age

Your insurer doesn’t know if you’re a reckless or careful rider. Therefore it has to use statistics to work out how likely you are to make a claim.

Unfortunately, these stats are stacked against younger bikers.

Those between 17 and 25 years of age are considered the riskiest age group, and so tend to have higher prices.

The bike you ride

As you’d expect, the more expensive or powerful your bike is, the more of a risk it poses.

A classic bike, for example, may cost more to repair than a new model, particularly if it’s rare and the cost of spare parts is higher.

But if you own a beaten-up old scooter, don’t assume that just because your bike isn’t worth much, it’ll be cheap to cover.

Also, bikes with larger engines are also more likely to be involved in an accident, so a super-charged ride would likely cost more to insure.

It’s worth noting that, if you decide to modify you motorbike, you need to tell your insurer about it.

This may increase your insurance premium. But not telling your insurer could invalidate any claims you make in the future.

How good your security is

Sport bike

The harder your motorcycle is to steal, the lower your premiums.

If you can keep the bike in a locked garage at night, this can help keep costs down. Anti-theft measures such as ground anchors, immobilisers and bike locks can also help.

Make sure any security devices you buy are recognised by the insurer you’re planning to use, otherwise you may not get a discount.

Where you live

Your postcode also has a bearing on the cost of insurance. If you live in a built-up area where the risk of accidents is greater, you’ll pay more.

You’re also likely to pay more if you live somewhere that has high recorded levels of bike theft.

How you use your bike

If you use your ride for commuting as well as for social reasons, you’re likely to pay more for cover. This is because you’ll be riding more when the roads are busy.

Your annual mileage also has a bearing. After all, the more time you spend on the road, the more likely you are to be involved in an accident.

Your riding record and no-claims bonus

One of the more significant factors in calculating your cost of cover is your claims history, and whether you have any points on your licence.

Your insurer will ask for details of any claims or convictions in the past five years. Even if a claim wasn’t your fault, you still need to tell them about it.

If you haven’t made any claims for a year or more, you should have some form of no-claims bonus.

Most insurers will accept up to five years’ worth of no-claims to give you a discount on your premium.

Your excess

The higher the voluntary excess you agree to, the less your insurance tends cost.

The drawback here is that, when you make a claim, that amount is deducted from your final payout.

If you have zero voluntary excess, your insurer sees that it’ll have to pay you the full amount of the claim, so your premiums tend to be higher.

The type of cover you buy

There are basic kinds of bike cover:

Third-party only (TPO)

Covers damage to other people, property and vehicles in accidents that are your fault.

Third-party, fire and theft (TPFT)

All the benefits of TPO, but your bike is also covered if it’s stolen or damaged by fire.


All the benefits of TPFT, but you’re also covered for damage to you and your bike, even if the accident was your fault.

Usually, the higher the level of cover you opt for, the higher your premiums are likely to be.

However, this sometimes isn’t the case, and a comprehensive policy can work out at a similar price to TPFT.

As always, take a look at quotes for the various levels of cover and see where you can get the best deal.
