My bike fell over while waiting for the other traffic

Do you mean the clutch handle or did you drop it on its side and crack open the clutch housing? Replacing the clutch handle is easy, the housing is a different story.

As for the mirror and paint, well thats all cosmetic and easy to repair.

Now to the important part are you OK?

As to what you need to do. Thats up to you. Do you want to fix this yourself or are you looking to get someone to fix it? If you'd like to do the fix yourself and would like some guidance we can help, we will need to know a few things first.

What kind of bike were you riding? Year and Model. And Is the bike running?

Can youpost pictures of the damage. The more information you provide the more help we can be.
