Saving and re-registering the chassis number

The loss of frame numbers is a fairly common problem on enduro bikes. This can happen due to painting or wear, for example. However, it is important to remember that the frame number will never disappear from the frame itself without significant intervention, such as grinding or heavy sanding.

Below are instructions on how you can try to save a chassis number in different situations:

1. Body number covered after painting

If your bike frame has been sandblasted and powder coated, the frame number can often still be found. Follow these steps:

• Use a thick carpet knife or paint scraper.

• Carefully scrape away the paint from the frame number until the number is visible on the bare metal.

• This method is usually sufficient for approval by authorities.

• Remember to cover any bare metal with a protective film, for example, to prevent the frame from rusting.

2. Frame number lost due to wear and tear

If the frame number has worn away, for example due to abrasion, it can often still be restored in the same way as after painting:

• Carefully use a paint scraper or carpet knife.

• When scraping, it's best to proceed slowly so you don't damage the metal further.

• Although a trace may remain visible, this method is usually sufficient for verification.

• Remember to cover any bare metal with a protective film, for example, to prevent the frame from rusting.

3. Frame number sanded or scratched Off

This is a rarer but sometimes occurring case. If the frame number has been completely removed:

Unfortunately, the only option in this case is to make a new chassis number.

Painting tip:

The frame number is an important part of the bike's identification and legality, so it is recommended to always check and protect the frame number before painting the frame or other major procedures.
