Koso 34mm Throttle Body Honda Grom MSX125

If you have upgraded your Grom's mill, you should be thinking about a larger throttle body so you can take full advantage. This 34MM number from Koso allows more air to flow into the engine, resulting in a better air/fuel mixture, better throttle response, and most importantly, more power.

Features:

• Controls the amount of air flowing to the engine
• Combine with Koso's Intake Manifold for a better air/fuel mixture
• Allows more air flow for better throttle response and more power
