The SCS system replaces your stock throttle tube with a bonded carbon fiber tube and grip system. This eliminates the need for grip glue or safety wire. The left grip features a 100 percent slip proof Pyton gripping system. This will be your first set of grips with identical exterior diameter. This system is great for quick, on-site grip replacements. If you want absolute confidence, this should be your primary grip. Sold in pairs. Fit for Ducati, Suzuki, Yamaha.
