Does Motorcycle Insurance Cover Custom Parts and Aftermarket Gear?

What Your Standard Policy Actually Covers

When you buy a motorcycle policy, the insurer is pricing coverage on the bike as it left the factory. The base value, the standard parts list, the manufacturer-installed components — that's what's covered under a standard comprehensive and collision policy.

Anything you've added or changed after you bought the bike is, by default, in a gray zone. Most standard policies do include a small amount of "miscellaneous accessories" or "custom equipment" coverage — typically $1,000-$3,000. But that number disappears quickly when you start adding up what riders actually spend on their bikes.

What Counts as Custom or Aftermarket Equipment?

Broadly, anything not included in the manufacturer's base model MSRP:

Aftermarket exhaust systems
Performance air intakes
Upgraded suspension components (forks, shocks, linkage kits)
Custom wheels
Upgraded brakes
Paint — custom paint jobs can be worth $2,000-$8,000 on a custom bike
Extended windscreens, crash guards, sliders
Luggage systems (hard cases, soft bags, tank bags)
Heated grips, electronic accessories
LED lighting and signal upgrades
GPS units and communication systems
Custom seats and upholstery
Performance ECU flashes (the software itself isn't a part, but the value added to the bike is)

On a well-specced touring bike or a custom cruiser, the aftermarket additions can easily exceed $5,000-$15,000. None of that is covered by the $1,000-$3,000 default accessory limit in most policies.

What Is a Custom Parts and Equipment (CPE) Endorsement?

This is the specific endorsement (add-on coverage) you need to protect aftermarket investment. A CPE endorsement extends your policy to cover custom and aftermarket parts at their actual replacement cost (or agreed value), typically up to a limit you select.

Most carriers offer CPE endorsements with limits up to $30,000, though common selections are $3,000, $5,000, $10,000, or $15,000.

Cost: Usually $30-$100/year for $5,000 in coverage. For $10,000-$15,000 of coverage, expect $80-$200/year. Extremely cost-effective compared to the potential loss.

The endorsement typically covers the same perils as your underlying collision and comprehensive coverage. If your custom exhaust is damaged in a crash, the CPE endorsement pays for it. If your custom paint is vandalized, it pays. If the bike is stolen, it pays for the full value including the custom parts.

Does the Default Accessory Coverage Include Riding Gear?

Usually not. Most default motorcycle policies explicitly exclude clothing and riding apparel from accessory coverage. A standard comprehensive and collision policy does not cover your:

Helmet
Riding jacket
Gloves
Boots
Overpants or protective pants
Armored base layers

A quality full set of riding gear — a $450 helmet, a $400 jacket, $150 gloves, $200 boots, $200 pants — is $1,400 that evaporates in a crash with no insurance remedy under a standard policy.

Riding Gear Coverage: Is It Available?

Some carriers specifically offer riding gear coverage as either a standalone endorsement or as part of a broader accessories package. Check with your insurer.

When available, it typically:

Covers helmets, jackets, gloves, boots, and protective pants
Has a combined limit (e.g., $1,000 or $2,000 per incident)
May have per-item sub-limits
Requires the gear to have been in use or on the bike at the time of the incident

Gear damaged in a crash is covered. Gear that wears out over time is not — that's normal wear, not an insured event.

If your insurer doesn't offer gear coverage, another option is checking whether your homeowners or renters policy covers personal property damaged off-premises. Some policies cover personal property globally up to a percentage of the total coverage limit, which might include expensive riding gear.

What Happens to Custom Parts in a Total Loss?

This is where the gap matters most. In a total loss — your bike is totaled in a crash or stolen and not recovered — the insurer determines Actual Cash Value. Without a CPE endorsement, ACV is based on the stock value of the bike. Your $4,000 in aftermarket work is simply not considered.

With a CPE endorsement, the custom parts are included in the total loss payout up to your endorsement limit. For a seriously customized bike, the difference can be thousands of dollars.

Should You Document Your Custom Parts?

Yes. Even with a CPE endorsement, the claims process goes much more smoothly if you can document what you had. Before adding expensive modifications:

Photograph everything — detailed photos of each component, serial numbers when visible
Keep receipts — both for parts and for labor if a shop installed them
Update your insurer — when you add significant value (new exhaust system, custom paint, wheel upgrade), call or update your policy in writing. If the endorsement limit you're carrying is $3,000 and you just added a $5,000 Öhlins suspension kit, you're underinsured at the current limit.

Updating coverage before something happens is far easier than arguing coverage limits after.

What About Bikes That Are Heavily Customized from the Factory?

Some bikes come from the factory with a lot of "standard" equipment that other bikes would call optional — premium audio systems on touring bikes, factory custom paint programs, heated grips, quickshifters. These are included in the purchase price and therefore in the standard ACV calculations. You don't need a CPE endorsement for factory-installed equipment.

The CPE question only applies to things you added after purchase.

What Is a Scheduled Article Rider?

For extremely valuable individual items — a one-of-a-kind custom paint job worth $8,000, a set of forged wheels worth $6,000, a Ducati Panigale V4 with significant performance work — you can sometimes "schedule" individual items on your policy with agreed values for each. This is common in high-end homeowners/renters policies for jewelry and art; it's less common in motorcycle insurance but available from specialty carriers.

If you have a high-end custom that would be difficult to value otherwise, ask a specialty motorcycle insurer (Markel, Foremost, Hagerty's motorcycle offerings) about scheduling individual items.

Common Coverage Gaps to Watch For

Dealer-installed accessories at time of purchase — these are sometimes covered as part of the purchase price, but ask your insurer explicitly. Dealers often list them as part of the financed amount, but insurers may treat them as aftermarket.
Performance modifications that increase the bike's risk profile — some aggressive performance modifications (engine work, turbos, significant power additions) need to be disclosed to your insurer. Some carriers will exclude them or surcharge, but non-disclosure is worse — it can void coverage on a claim.
Custom parts that affect safety systems — removing or replacing brakes, traction control, ABS, or other safety systems should always be disclosed.

Bottom Line

A standard motorcycle policy's accessory coverage is a thin baseline, not a real protection for riders who invest in their bikes. If you've spent more than $2,000 on aftermarket equipment, get a CPE endorsement sized to cover it. If you ride in full gear, check whether your policy or homeowners coverage includes gear protection. Document everything with photos and receipts. The endorsement cost is genuinely minimal compared to the customization investment it protects.
