I just bought a CBR600 F2 with the most hideous handle bars which I of course want to replace. I'm looking for something black/chrome instead of just the boring original ones. I found an e-shop which has more than 60 different types of bars but I'm not quite sure which size I should get? As far as i know the original messurements are 22mm in diameter and 122mm lenght? If the diameter fits will it matter if the bars are a bit shorter or a bit longer?
