Your bike has been written off. Now what?

6 min readUpdated Jul 2026

A write-off offer is frequently the first thing riders disagree with after a crash, and often with good reason. The first figure offered is a valuation, not a fixed price, and valuations can be challenged with evidence. This guide explains how they are reached and what riders commonly get wrong. It is general information, not advice about your own bike.

What the write-off categories actually mean

A bike is normally written off when the cost of repair is uneconomic relative to its value, not necessarily when it is beyond repair. Category A and B are the most severe and mean the machine, or at least its frame, must be destroyed. Category S indicates structural damage that was repaired or repairable, and Category N indicates non-structural damage. The category affects both what happens to the bike and its future value, so it is worth knowing which one is being applied and why.

How your bike gets valued

Valuations are typically based on what it would cost to replace your bike with one of similar age, mileage and condition, rather than what you paid or what you owe on finance. Trade guides are commonly used as a starting point, but they are a starting point. They frequently fail to reflect genuine condition, service history, low mileage or the money riders have put into a machine.

Why the first offer is often low, and what to do

Evidence is what moves a valuation. Advertised prices for genuinely comparable bikes, ideally several, carry real weight, as do service records, MOT history, receipts for parts and any documentation of condition. Photographs taken before the accident help. If the offer does not reflect the bike you actually owned, say so and show why, rather than accepting it as final.

Where non-fault changes the picture

If the crash was not your fault, the valuation is part of a wider set of losses being pursued against the other side, which can also include your gear, your excess, and a replacement bike while things are resolved. Riders sometimes accept a low write-off figure without realising the rest of it was recoverable too.

Common questions

Questions riders ask

Answers to common queries regarding the claims process.

Sometimes, depending on the category and the insurer. Retaining salvage usually reduces the payment you receive. Category A and B machines cannot be returned to the road.

This is negative equity and it is common, particularly early in a finance agreement. Some riders hold GAP insurance which is intended for exactly this gap. It is worth checking whether you do.

With evidence rather than argument. Gather advertisements for genuinely comparable bikes, your service history and any receipts, and set out clearly why the machine was worth more than the offer reflects.

It can, depending on who is held responsible and how the claim is recorded. Where another party caused the accident, the position may be different.
