The RSI TB-4 Billet Throttle Block with Push-Button Kill Switch is a direct replacement throttle block assembly designed for a smaller, stronger profile than the stock unit. CNC machined from 6061-T6 billet aluminum, it provides a solid construction for handlebar use while retaining the stock throttle lever and lever pivot.
Its two-piece design clamps securely onto the handlebars and is designed not to spin or pop off during demanding riding conditions. The slim profile also opens additional handlebar space for accessories such as handguards, mountain bars and GPS equipment.
Built-in wire channels allow heater wires to pass through the assembly for a clean appearance and installation. The RSI TB-4 combines durable billet construction, a space-saving design and compatibility with the stock throttle lever and pivot in a direct replacement assembly.
