As you may have seen below I have posted a little something on the top speed. Besides the tiny little whole in my seat (which occured when my mom and stepdad decided they need some room in the garage and st it and and my CR-125 out in the drive way entirely too close together on a windy day the 125 fell onto the R6 bringing tears to my eyes)the bike is bone stock. I have had the speedometer read 167 and i plan on making it go a little faster than that hear in the next couple of days if the weather will let me get it out. How fast have you had yours?
