How do I make a game like exite bike

would it be possible to keep the player "on rails" like in exitebike and still being able to make the character jump and land in the right place ?

i have tried some things with the custom movement and plataform behavior but i couldn't make it work.

You can make something a little like Trials Fusion, which has very similar controls and mechanics to ExciteBike. This is a fantastic tutorial I've followed in the past:
