Yoshimura Steering Stem Nut Kawasaki Ninja 300 / 250R 5 5 3 3
Talk about a simple weight reduction! When I pulled out the stock stem nut and held this one in my had I was shocked at how much weight I lost just from something this quick and easy to replace July 20, 2015
Love it! This took 5 minutes to install, torqued to spec and it looks a load nicer than the standard shiny nut. I bought the Grey one to go with my other grey parts. January 24, 2015
Looks better then stock Installation was a breeze torque wrench is required. The nut is about 1/5 the weight of the original nut and 100% better looking. If i were to install again i would taped off the edges (socket left little scars on nut where it was torqued down) October 25, 2013
