Hahaha, I'm gonna keep out of that. Redstar11 knows he's wrong, he's being a troll, and I'm not gonna feed him.
I will say that reason 900RR parts are easy to find is because it's the most popular stunt bike out there and gets wrecked so much that there are always spare parts available for cheap.
The Ninja 500 is a great bike, don't let anyone tell you it's not!
