28mm Throttle Body for Honda Grom & Monkey 2022+

28mm Throttle Body for Honda Grom & Monkey 2022+

This 28mm throttle body is an upgrade built for 2022-and-newer Honda Grom and Monkey 125 bikes. By opening up the airflow into the engine, it aims to give quicker throttle response and more power. If you're browsing mini bike & pocket bike parts, this is a worthwhile piece to consider. It replaces the stock throttle body and suits performance-minded builds.

Performance Advantages

The throttle body uses a 28mm bore, which lets more air pass through while keeping low-end torque intact. A precision-machined inner bore and a high-tolerance butterfly valve reduce turbulence, so the throttle feels smooth. It is designed to connect with the factory sensors, so the ECU keeps communicating normally.

Installation Considerations

For the best outcome, pair this throttle body with the recommended 23-29mm Intake Manifold DP640000. An ECU reset or fuel controller is strongly suggested for proper operation. After installing, reset the throttle position sensor so the ECU can learn the new butterfly position at idle, which helps you get the full benefit of the upgrade.
