This is the biggest Grom big bore kit on the market for your Grom or Monkey 125! The all aluminum ceramic coated cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker).This new big bore kit will provide the extra power to make your new Grom or Monkey a lot more fun to ride! High quality parts and requires no machining to the cases.

The Oil Cooler Kit is a high quality accessory designed to help the Honda horizontal engine keep cooler. Air-cooled engines run hotter when modified (with big bore kits) and/or subjected to heavy loads such as racing use. This kit will help the engine’s durability and reliability by circulating the engine oil through a cooler reducing the engine’s oil temperature.

NOTES:

Aftermarket fuel controller and upgraded fuel injector is required. Professional installation is highly recommended!

Performance upgrades to the clutch is highly recommended!
