I've only changed bikes when they've died or been killed (except changing the CG125 for the GT750).
The GT was killed by a moron that ran me off the road.
The CB900 blew it's gear box (Grouch desease).
The CB750 just died under me.
I was knocked off the GPZ600.
Basically every bike I've had has been the right bike at the time and I've been sad to see the going of all of them.
I'm 47, have never owned a car licence and never wanted one.
I ride all year round pretty much every day (but not in the snow, I'm not insane).
Why do I love bikes? Couldn't tell you, it's not a thing that can be put into words.
Welcome to YOC and to bikes.
It's worth repeating what's already been said, when you get out on the road take it easy.
Remember the bike only goes as fast as you make it go, don't make it go too fast until you have a bit more confidence.
Not sure about that, sorry. The part is called a tail panel so maybe look for a 2013 version (try wemoto) unless someone else here can say whether it will fit your bike or not.

This is the one for the other side.
