I'm on a 2007 zx6r and noticed the other day I'm runnin Tokico brakes in back and Nissin in the front. Thought it was an upgrade from the kid I bought it off of then I realized another 07' at bike night had same set up. Anybody know why Kawi decided to run Nissans in front and tokico in back? my buddys 2006 has all tokico as does my dads 2009...confused
