**IMPORTANT NOTE FOR Z125's: It is recommended that a professional technician make sure the bike is tuned properly after install. An aftermarket fuel controller is required and possibly an autotune will be needed to prevent a lean condition and damage to your engine. Additionally, a performance exhaust is also recommended as the stock exhaust is restrictive and may cause your engine to run hotter.
