diameter

Hey everyone, Just picked up my MT-07 LAMS over the weekend and so far I'm very impressed with the bike, little disappointed with the brakes but I'm hoping they will get better as they bed in a bit more. I'm looking to do the unrestricted modifications on the bike at some point in regards to...

I was thinking of getting these, but I would like to know the diameter of them. I wanted to know if I can put a gopro roll bar mount on them, I know the mount can handle 1.4" to 2.5" (3.5cm to 6.35cm) diameter tubing. Just wanted to know if the Evotech was within that size before I buy.
