Kitaco
In December 2022, Kitaco, a Japanese manufacturer of performance parts and accessories, unveiled two big bore kits for the Honda CT125 Hunter Cub. Enthusiasts seeking upgrades could opt for either a 164cc or a 181cc kit. These kits contained components such as cast aluminium cylinders, pistons, piston rings, gaskets, I-map injection controllers, and oil coolers, offering a comprehensive solution for the conversion process.
Performance Parts
Fast forward to August 2023, and Kitaco expanded its offerings to include Honda Monkey and Grom (MSX 125) owners. Kitaco’s Tuning Menu provided options for these models, featuring a 125cc high compression piston, Light 164cc or 181cc big bore kits, Neo 164cc or 181cc big bore kits, and an extravagant dual overhead cam (DOHC) 181cc big bore kit.
Tuning
Distinct from previous kits, the Light and Neo kits for the Monkey and Grom did not include high-performance camshafts and large-capacity fuel injectors. These components required separate purchases, along with the option of acquiring the I-Map controller and wiring harness for convenient fuel injection mapping adjustments—no intricate wiring modifications needed, just a plug-and-play setup.
Pricing
Concerned about aesthetics? Kitaco offered customization with black or silver cylinder options for both the 164cc and 181cc big bore kits. Pricing details as of August 16, 2023, were as follows: ¥17,600 (about $121) including tax for the black 164cc kit, ¥16,500 (about $113) including tax for the silver 164cc kit, ¥18,700 (about $128) with tax for the black 181cc kit, and ¥17,600 (about $121) for the silver 181cc kit.
Cast aluminum cylinder
The pinnacle of their offerings was the DOHC 181cc big bore kit, boasting an entirely new cylinder head with reshaped ports, larger valves, camshaft, piston, piston rings, hardware, and gaskets. This kit pushed the boundaries of performance for Monkey and Grom models without necessitating a full engine swap. The price for this extreme upgrade was ¥275,000 (about $1,886), tax included, and it was available only in silver.
Conclusion
Furthermore, Kitaco took steps to make its offerings accessible to a wider audience of Honda minimoto enthusiasts by providing instructions in both Japanese and English, enhancing the user experience for its products.
