The stock, vulcanized grips on newer Kawasaki's are a pain. This is a great replacement for the weak stock plastic piece. I've been down several times and never experienced an issue from this tube.
Direct O.E.M. replacement, but with high-quality billet aluminum instead of cheap plastic. Inside the Pro Taper aluminum throttle tube is Teflon-coated to reduce friction between the tube and your handlebar. A knurled finish provides a solid bond between tube and grip.
