Honda Monkey 125 more power – The development of engine tuning for the Honda Monkey, MSX 125 Grom, or Dax has been around almost as long as the mini bikes themselves. In 2023, from Japan, there’s a breakthrough: the Kitaco kit with DOHC, 4 valves, 181 cubic centimeters – and more than 20 horsepower.
Kitaco is a Japanese company specializing in technical accessories, tuning parts, and kits. Kitaco Parts & Kits are specifically designed for Honda’s iconic mini bikes, namely the Monkey, Dax, and MSX 125 Grom.
Honda Monkey 125 more power – Kitaco Big Bore Kit for Honda Monkey and MSX 125 Grom
Starting from July 2023, Kitaco has launched its highly anticipated, state-of-the-art tuning kit specifically designed for the Monkey & Co. series. This advanced big bore kit notably enhances engine capacity, expanding it from 125cc to an impressive 181cc. This significant upgrade is not just about increased displacement; it also includes a sophisticated head assembly featuring a dual overhead camshaft (DOHC) design and a four-valve configuration on the top end. This combination represents a major leap in performance and efficiency, offering riders improved power delivery, smoother acceleration, and a more responsive riding experience. The integration of these high-performance components ensures that the engine not only delivers more power but does so with greater reliability and durability, making it an ideal choice for both casual riders and enthusiasts seeking to elevate their riding experience.
Honda Monkey 125 more power – 181 cubic metres, twin camshaft and 4 valves for the single cylinder
Japanese engineers are making a remarkable technical effort to innovate the classic Honda engine, focusing on the air-cooled, four-stroke single-cylinder model. This iconic engine, known for its reliability and efficiency, features an overhead camshaft (OHC) and two original valves. Historically, this engine has been celebrated for its nearly 10 horsepower output, which, while modest by modern standards, was a significant achievement at the time of its introduction. The engineers are exploring ways to enhance its performance and efficiency, combining traditional engineering principles with modern technological advancements. This project reflects a blend of respect for the engine’s storied past and a forward-looking approach to engineering, demonstrating a commitment to preserving and improving upon a key piece of Honda’s automotive legacy.
Honda Monkey 125 more power – Cult minibike from Honda with over 20 HP
According to Kitaco, it’s possible to achieve over 20 horsepower at speeds exceeding 10,000 revolutions per minute. This impressive feat is made feasible not only due to the increased displacement but also because of the fixed-speed valve train. A significant contributing factor is the heightened compression ratio, which has been elevated from approximately 10 to 11.5. To facilitate this, a lighter forged piston is employed, mounted on an H-profiled, lighter connecting rod.
The big-bore cylinder used in this configuration is crafted from aluminum, featuring a traditional steel liner on the inside and cooling fins on the outside for effective heat dissipation. This comprehensive kit also includes other essential components such as the timing chain, camshafts, rocker arms, valves complete with springs, spark plugs, and gaskets.
These enhancements not only boost the engine’s power output but also improve its efficiency and reliability. The use of lightweight materials like forged pistons and H-profile connecting rods reduces the overall weight, contributing to a more responsive and agile performance. The increased compression ratio extracts more power from each combustion cycle, making the engine more powerful without significantly increasing its size.
Furthermore, the aluminum big-bore cylinder with its steel liner ensures durability while effectively managing the engine’s thermal dynamics, thanks to the external cooling fins. The inclusion of high-quality components like the timing chain, camshafts, and valves ensures that each part of the engine works in harmony, leading to smoother operation and extended longevity.
Overall, Kitaco’s approach to enhancing engine performance exemplifies a blend of advanced engineering, quality materials, and attention to detail, resulting in a significantly improved power output and efficiency while maintaining the reliability and durability of the engine.
Honda Monkey 125 more power – For previous types JB02, JC61 and JC75
Initially, the superior tuning kit from Kitaco was exclusively compatible with the Honda models JB02 (Monkey 125) and JC61 and JC75 (MSX 125 Grom) up to the year 2021. These models featured a slightly shorter engine stroke with a piston size of 57.9 millimeters. To enhance performance, Kitaco’s upgrade involved enlarging the bore of the cylinder and piston from 52.4 to 63 millimeters. This modification effectively increased the engine displacement from 125cc to 181cc.
Further elaborating on the advantages of this tuning kit, it’s designed to boost the overall power and efficiency of the engine. The increase in bore size allows for more air-fuel mixture to enter the combustion chamber, resulting in a more powerful explosion and, consequently, greater horsepower and torque. This modification is particularly beneficial for riders looking for improved acceleration and hill-climbing capabilities.
Moreover, Kitaco’s tuning kit includes high-quality components that ensure reliability and durability. The larger pistons are made from superior materials that can withstand higher pressures and temperatures, which is crucial for maintaining engine integrity during intense riding conditions. Additionally, the kit comes with a detailed installation guide, making it accessible for enthusiasts who prefer to upgrade their bikes themselves.
The adaptation of such tuning kits is a testament to the evolving landscape of motorcycle customization. It reflects the growing demand for personalization and performance enhancements among biking enthusiasts. With the rise of new technologies and materials, the possibilities for upgrading and customizing motorcycles are continually expanding, allowing riders to tailor their machines to their specific riding styles and performance needs.
Honda Monkey 125 more power – Honda Monkey and MSX Grom’s Powerful Enhancement: Kitaco’s Nearly 200cc Possibility
Kitaco, a renowned tuning company, has not yet released their top-of-the-line tuning kit for the latest models of Honda Monkey, MSX 125 Grom, and Dax 125. These bikes originally feature a 50-millimeter bore and a 63.1-millimeter stroke. With an extended stroke and a 63 big bore, the engines could potentially reach an impressive 197 cubic centimeters.
Honda Monkey 125 more power – Kitaco’s Tuning Kit: An Expensive Upgrade
The comprehensive tuning kit, which includes a dual overhead camshaft (DOHC) and a 4-valve system, expands the engine capacity to 181cc. As of August 2023, this kit is priced at approximately 1,700 euros (or 275,000 yen). Kitaco also offers additional tuning parts, such as larger fuel injection nozzles, electronic control units, exhaust systems, reinforced clutches, and oil radiators. However, there is no information on whether these components are approved by the German TÜV for road registration, which means a modified Honda Monkey or MSX Grom might not be street-legal in Germany.
Honda Monkey 125 more power – Top Speed and Modifications
One of the most significant changes is the recommendation to adjust the final drive ratio. This modification is expected to increase the top speed of these mini-motorbikes from just under 100 km/h to at least 130 km/h. Accompanying this speed boost are upgrades for the chassis and brakes, also available from Kitaco.
Conclusion: Powering Up Honda’s Cult Mini Bikes
Honda’s iconic mini motorcycles are transformed into powerful machines with Kitaco’s tuning kit from Japan. With significant technical enhancements – including DOHC, a 4-valve system, and an increase in displacement from 125 to 181 cubic centimeters – Kitaco manages to extract over 20 horsepower from the old air-cooled four-stroke single-cylinder engine.
The premium tuning kit, available since July 2023 for around 1,700 euros, is currently only for earlier versions of the Honda Monkey 125 and MSX 125 Grom, up to the 2021 models. Kits for newer models and the Dax 125 may soon follow. However, there’s a catch for enthusiasts in Europe: these modifications are not legally permissible for public roads.
