What is modified bike insurance?

Also known as custom motorcycle insurance, this is specifically tailored to cover the potential increases in bike value and claim risk that aftermarket mods can cause.

Making modifications to a motorcycle can change the way it performs and increase its value. These two factors mean that modified bikes require insurance policies that consider the changes that have been made and reflect them in the level of coverage and the premium you pay.

While a range of minor bike mods can usually be covered with a regular bike insurance policy, some insurers have a limit on how many modifications they’ll accept, or how drastic the modifications are. In these cases, you need a specialist.

Types of bike modifications

There is a huge range of potential modifications you can make to your motorcycle, but they generally fit into two main categories.


Physical bike modifications are usually bodywork changes that affect the way your bike looks or add functionality that isn’t performance-based. They’re commonly made to make motorcycles more attractive or better suited to their use.

They can include:

  • A tail tidy
  • Crash bobbins
  • Radiator protectors
  • Aftermarket indicators
  • Heated grips


Performance bike modifications are entirely focused on changing the way your bike rides. They’ll usually make your bike more powerful, easier to handle, or able to conquer different terrain.

They can include:

  • An aftermarket exhaust
  • Clutch or brake levers
  • Aftermarket air filters
  • Engine tuning
  • New brake pads

The cost of modified bike insurance

Is insurance more expensive for modified bikes? Well, that depends. Different types of modifications alter your motorbike in different ways, and the more they change the way it rides or the value it holds, the more likely it is to affect your premium.

This is down to three main reasons. Firstly, modifications generally increase the value of your bike, making it more expensive to repair or replace. Secondly, visible modifications that make your bike more attractive might also make it more attractive to thieves, potentially increasing the chances of it being stolen. Finally, performance-based modifications that increase your motorbike’s speed or acceleration could be seen as a factor that increases the risk of you being in a road incident or collision.

Some bike modifications, such as heated grips and aftermarket indicators, aren’t likely to affect your premium by much (or at all) as they don’t increase the risk that you pose as a policyholder and also don’t significantly increase the value of your motorcycle.

However, as you start to stray into more substantial modifications, such as a new exhaust or a heavily tuned engine, you’re more likely to pay for it when it comes to insuring your bike.

Modified bike insurance premiums are calculated using a huge range of other factors, so there’s no way of knowing exactly how much modifications will add to your policy price.


Are there any modifications that make custom motorcycle insurance cheaper?

It’s a common myth that all bike mods will make your insurance more expensive when, in some cases, they can make your insurance cheaper. Security modifications such as built in steering locks and electronic immobilisers make it less likely that your bike will be stolen, potentially resulting in cheaper insurance. As with anything, this depends on the insurer’s specific policies.

How do I get cheaper modified bike insurance?

There are plenty of ways you can try to reduce the price of insurance for a modified bike, just as with any other type of motorbike. They include investing in security features that make your bike less likely to be stolen, reducing the amount of mileage you cover, and working towards building a no claims bonus.

What happens if I don’t tell insurers about bike modifications I’ve made?

Withholding information from insurers about any modifications you’ve made to your bike could see your policy be invalidated. It’s essential that you accurately portray the modifications you’ve made to your bike to make sure that, if you come to make a claim, your insurance is valid.
