# How to create a Motorcycle Controller

## Vehicle First Steps 

1- Place motorcycle model in the scene, set layer of car to **Vehicle**(8) and Unpack Prefab

2- Add <mark style="color:green;">Colliders</mark> and <mark style="color:green;">Rigidbody</mark> (set a high value for the mass of the vehicle, like <mark style="color:red;">100</mark>)

3- Create Wheel Colliders for each wheel model

4- Add **Motorcycle Controller component** and assign <mark style="color:blue;">wheel models</mark> and <mark style="color:green;">wheel colliders</mark> in same sequence:

5- Assign Steering Wheel

6- Set the Center of Mass

7- Create a vehicle enter trigger

8- Create and assign **Inverse Kinematic Target Positions**

The above steps are the same as the [car setup](/ju-tps-documentation/game-development/how-to-use-vehicle-system/how-to-create-a-car-controller.md), see the [page ](/ju-tps-documentation/game-development/how-to-use-vehicle-system/how-to-create-a-car-controller.md)for more details

{% hint style="success" %}
Tip: if you place the center of mass at the height of the wheels and further back, as in the image above, you will get good results

## Motorcycle Parameters

Motorbike physics has some unique parameters:

[Overturn Check](/ju-tps-documentation/game-development/how-to-use-vehicle-system/standard-vehicle-configuration.md#anti-overturn-checker-parameters) is the same for any vehicle.

## Motorcycle Suspension

Up to this point the bike will be working normally, however it is interesting to use a suspension script:
