IMPORTANT UPDATE: These bore kits are only for the 2021 and older models (will not work on the new 2022 models as the engine has been redesigned)
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.
