Upgrade your 2022+ Grom with the Takegawa Big Bore Kit, elevating the displacement from the stock 124cc to 145cc. Experience a substantial boost in both power and torque compared to the standard setup. For optimal performance, we recommend fine-tuning the fuel using the aRacer Mini X paired with the Wideband AF2 auto tuner.
With the notable increase in engine power and torque resulting from the SP Takegawa big bore kit, the crankshaft faces heightened torsion and deflection. To mitigate these effects and reduce the load on the crankshaft, SP TAKEGAWA recommends installing a crankshaft support adapter concurrently with the big bore kit.
