Indian Thunderstroke 116 Stage 2 Performance Kit

This Thunderstroke Performance Kit delivers up to 17% more horsepower* than a stock Thunderstroke 116 ci engine. Enjoy responsive, punchy acceleration from a stop and plenty of no-lag passing power at highway speeds. With this kit, you’ll never compromise reliability or ride quality. Plus, Indian Motorcycle stands behind every accessory with warranty protection and the guarantee that you'll never void your motorcycle’s warranty when you install a factory-backed stage kit. This Stage 2 Kit must be installed in-conjunction with a Stage 1 Air Intake and Stage 1 Slip-On Exhaust Kit (each required and sold separately). This kit includes a card with a unique calibration code that upgrades your Engine Control Module (ECM) software from a standard set-up. This software upgrade is required to ensure peak performance; therefore, dealer installation is required. *Increase results may vary depending on specific testing conditions. This accessory is not compliant on any Chief model for use in California.
