Welcome! Do not buy an OEM clip-on. They are way expensive as apposed to an aftermarket clip-on, and most aftermarkets have replacement tubes that you can pick up for around 20 dollars if it happens again.
Brands to look at are:
Apex.
Apex Adjustable Clip Ons - Sport Bike Track Gear
Driven.
Driven Clip-Ons - Sport Bike Track Gear
Woodcraft.

Vortex.
Vortex Clip-Ons - 7 Degree - RevZilla
And probably a few others I didn't list.
I believe you need a 50mm. Someone with a 13-15 might need to chime in on that one.
Install is pretty simple. Remove the top triple clamp. (2 bolts at each side, and the steering nut. Your clip-ons should be bolted onto the bottom of the triple clamp as well, so remove those too.) Take the clamp off, loosen the old clip-ons and slide them off. Put the new ones on and then the triple clamp and you are good to go. A lot of the aftermarket brand clip-ons are designed to be able to be put on and taken off without having to remove the top triple again, so that's a plus!
