How to Register a Modified Bike in India 

It’s widely known that for a large number of people in India, motorbikes are their daily mode of transport. Many people are also very passionate about bikes and often modify their two-wheelers to make them look or perform differently. However, there are legal implications to modifying bikes as making too many changes to a bike can prove to be dangerous. The good news is, you can get your bike modified within the legal parameters and get it properly registered with the RTO. Read on to know how you can register a modified bike in India.. 

Steps to Register a Modified Bike in India

Before you start modifying your bike, you should understand why the excessive modification of bikes is illegal as per the Motor Vehicles Act, 1988. Altering the structure or parts of the bike can have an impact on the technical performance of the bike and lead to accidents. For instance, if an excessively powerful engine is fitted in a bike built for a low-powered engine, the bike may end up causing an accident on the road due to technical malfunction. However, if you still want to make minor changes, you can do so by taking proper approval from the RTO. Given below are the steps to register a modified bike in India.


  1. Before you start with any kind of modifications on your bike, you need to take approval from the RTO.

  2. Note that RTO will allow for only minor cosmetic modifications to your bike so that it does not affect the performance of the bike and safety in any way.

  3. When your proposed modifications are approved by the RTO, you will have to get them registered on the registration certificate and your bike will be then regarded as a modified bike.

  4. Once the above processes have been completed, you can go ahead with applying the modifications to your bike.

  5. The modifications made must exactly match the modifications you applied for at the RTO or your bike may end up getting seized.

If you fail to get legal approval from the ARAI and go ahead with the modifications, you will risk getting your registration cancelled. If you do change the structure of the bike from what it originally was without any approval, your bike will be listed as illegal.

The authorities are already taking stringent action in this respect; the State Police, especially from Kerala and Karnataka, have started a crackdown on modified motorcycles. It is envisaged that the other states and UTs will soon follow suit.

What Can be Legally Modified in a Bike?

Now that you are aware of the process of applying for a modification to your bike, it is also important to know the kinds of modifications you can legally apply to your bike:

  1. You can legally change the colour of your bike. However, you can only do so as per the list of colours approved by the RTO. Moreover, you will have to take prior permission from the RTO for making any colour changes.

  2. Very minor physical changes such as replacing the visors, decals, winglets, etc are allowed.

  3. You can change the tyres of your bike if your bike company provides alternate tyres for the specific model of your bike. You cannot use any tyres other than the company-approved set of tyres.

  4. You also have the option to change your engine if the existing engine on your bike has been damaged beyond repair. However, you will need to take prior permission from the RTO to replace your engine.

How to Take Permission from the RTO for Colour Changes

One of the most frequently asked questions when it comes to modifying bikes is how to get approval from the RTO for changing the colour on your bike. Read on to know the step by step process:


  1. Visit your nearest RTO office along with your RC book and a sample of the new colour you wish to change your bike to.

  2. Fill the NAVM form for colour available at the RTO and get a signed letter of approval from the RTO for the colour change.

  3. Once you have gotten approval, visit a reputed bike workshop and get the colour of your bike changed. Make sure you only use high-quality materials.

  4. Go to the RTO with all your documents and the bike and get confirmation and verification that everything is as per the RTO guidelines.

  5. Once the RTO has approved the modifications, get the changes marked in your RC book by the relevant RTO official.

  6. It should be noted that the RTO has prohibited using olive green or military green colours for civilian use, as they are only reserved for the defence forces.

To Conclude

If you are planning to make major changes to your bike, it is always a good idea to take approval from the ARAI and RTO beforehand. In case the authorities catch you with a modified bike but without papers for approval of modifications, your bike may get confiscated and you may have to face legal action. Hence, make sure all your documentation is in place before you make any modifications. You should also keep your vehicle protected with a two-wheeler insurance policy so that you are always financially covered in case of accidents.
