These figures are those published by KITACO on its company information page and are subject to change.[1]

Foundation and early years

KITACO traces its origins to April 1971, when it began operations in Higashi-Osaka dealing in the wholesale distribution of parts and accessories for both motorcycles and automobiles.[1]

A significant transition occurred in April 1975 when KITACO began planning, developing, manufacturing, and wholesaling its own special motorcycle parts. Concurrently, the company moved its headquarters within Higashi-Osaka and adopted the name “KITACO”, marking its shift from a general parts wholesaler to a developer and manufacturer of aftermarket motorcycle components.[1]

Expansion and corporate development

The company completed a new building in Higashi-Osaka in 1980 and restructured as a corporation in 1983. In 1990, KITACO established its Nara Distribution Center to strengthen logistics and distribution capabilities.[1]

In 2004, KITACO completed its present headquarters building in Nagata, Higashi-Osaka, and relocated its headquarters operations there. In July 2012, the company established KITACO (THAILAND) CO., LTD., extending its corporate presence outside Japan.[1]

KITACO produces a wide variety of motorcycle components divided into numerous technical categories covering both performance and maintenance.

Engine components

Engine tuning is one of KITACO’s most recognisable areas. Products include components intended for modified or high-tuned engines, such as oil pumps, crankshaft components, engine hardware, and other internal or supporting parts.

For example, KITACO offers a Super Oil Pump Kit for several Honda small motorcycles. The company states that the kit can increase oil flow by up to 25%, with the purpose of improving cooling and lubrication for tuned engines. KITACO also produces components for Honda’s Mini and Cub-derived engine families, including products compatible with models such as the Monkey 125, Dax 125, Grom, Super Cub, Cross Cub, and CT125.

Big-bore and performance tuning

KITACO has historically produced parts associated with increasing engine performance and supporting modified engines. This is particularly relevant to Honda’s small-engine ecosystem, including the Monkey, Super Cub, Grom, Dax, and related platforms. Rather than treating customisation purely as cosmetic modification, KITACO’s catalogue includes parts intended to support the mechanical requirements of a tuned engine, such as lubrication and valvetrain components.

Drivetrain

The company produces drivetrain components such as sprocket-related parts, hub dampers, and other transmission or final-drive hardware. Its replacement hub damper, for example, is listed for applications including the Monkey 125, Dax 125, Grom, and Super Cub C125.

Suspension and chassis

Suspension is another significant category. KITACO offers products such as:

• Front-fork springs
• Fork oil
• Preload adjusters
• Fork seals
• Suspension accessories
• Chassis hardware

For the Grom, Monkey 125, and Dax 125, KITACO offers fork-related products designed to alter suspension characteristics and support both street and circuit applications. One of its fork-spring products, for example, is offered in several spring rates and is described as suitable for street and circuit use.

Brake components

KITACO’s catalogue includes brake hardware and brake pads. An important part of its brake-parts business is its range of SBS Brake Pads, covering different compounds and intended uses. The catalogue lists ceramic, sintered-metal, carbon, dual-carbon, and dual-sinter formulations, ranging from street-oriented products to racing applications.

The company’s brake-pad applications extend across numerous motorcycle manufacturers, including Honda, Yamaha, Suzuki, Kawasaki, Ducati, KTM, MV Agusta, Triumph, and others.

Body and appearance parts

Not all KITACO products are performance components. The company also produces parts intended to personalise a motorcycle’s appearance, including machined aluminium accessories, covers, caps, bolts, grab bars, and other dress-up components. For example, KITACO sells an aluminium-machined front-fork top-bolt set with anodised finishes for the Grom, Monkey 125, and Dax 125. This illustrates an important characteristic of KITACO: the company operates across both functional performance modification and visual customisation.

Maintenance and replacement parts

KITACO supplies standard service and replacement components. Its K-PIT line, for example, includes maintenance-oriented parts such as fork seals and replacement hardware. Consequently, KITACO should not be viewed solely as a racing parts manufacturer; its catalogue spans performance tuning, maintenance, replacement parts, and cosmetic customisation.

KITACO products are particularly associated with Japanese motorcycles. The company’s current and archived catalogues show extensive applications for Honda, Yamaha, Suzuki, and Kawasaki. Its products also cover motorcycles from other manufacturers, particularly in the brake-pad range.

Honda

Honda is arguably one of the most important platforms in KITACO’s product ecosystem. The company has extensive applications for Honda’s small motorcycles, including:

• Monkey
• Monkey 125
• Grom
• Dax 125
• Super Cub
• Super Cub C125
• Cross Cub
• CT125 Hunter Cub
• Ape
• Various older Mini and Cub models

KITACO’s own vehicle-feature archive includes dedicated coverage for models such as the Monkey 125, Grom, Dax 125, Super Cub C125, CT125 Hunter Cub, PCX, ADV160, and Honda GB350/S. This concentration on small Honda motorcycles is a major part of KITACO’s identity.

One of KITACO’s defining characteristics is its strong connection to Japan’s mini-bike and small-displacement tuning culture. The company’s older English catalogue specifically organised products around platforms such as:

• XR50R / CRF50F
• TT-R50
• ZOOMER
• KSR110 / KLX110
• PCX
• CBR250R
• 4-stroke Mini Monkey
• 4-stroke Mini Ape
• Kawasaki Mini
• Yamaha Mini
• Scooters
• 250-class motorcycles
• Universal parts

This history helps explain why the KITACO name is strongly associated with compact Japanese motorcycles and customisation.

KITACO occupies a distinct position in the motorcycle aftermarket. While companies may approach aftermarket parts from various directions—replacement, dress-up, performance, competition, or complete tuning systems—KITACO operates across all of these areas. Its catalogue includes inexpensive replacement hardware alongside considerably more specialised engine, suspension, brake, and racing-oriented components. That breadth makes it possible for a rider to use KITACO parts for anything from a simple cosmetic customisation to a substantially modified motorcycle.

Relationship with manufacturers

Although KITACO is an aftermarket company rather than a motorcycle manufacturer, its company information lists major Japanese motorcycle-related businesses among its principal business partners, including Honda Motorcycle Japan, Yamaha Motor, Kawasaki Motors Japan, Suzuki Motorcycle, Suzuki Business, and Yamaha’s Y’s Gear.[1] This places KITACO within Japan’s broader professional motorcycle-parts distribution ecosystem rather than being simply a small independent tuning shop. However, it is distinct from being an OEM subsidiary of Honda, Yamaha, Suzuki, or Kawasaki.

Product philosophy

KITACO’s catalogue suggests several recurring priorities:

• Performance: Many products are designed specifically to support improved engine output, cooling, braking, suspension performance, or durability.
• Compatibility: KITACO frequently specifies exact motorcycle model codes and production ranges. This is particularly important for Japanese motorcycles because seemingly identical models can have substantial component differences between generations.
• Reliability: A number of products are positioned not simply as performance upgrades but as durable replacement or supporting components. For example, KITACO describes some components as intended for high-tuned engines or as replacements meeting genuine-equipment dimensions.
• Customisation: The company also embraces the enthusiast side of motorcycles, offering anodised, machined, coloured, and otherwise visually distinctive components.

KITACO maintains a substantial catalogue system rather than relying solely on individual product pages. Its official site provides product search, English and Japanese product information, vehicle-specific catalogues, universal-parts catalogues, SBS brake-pad search, inventory information, PDF catalogues, and product/application information.

The company’s extensive application information is particularly useful for owners of Japanese motorcycles because compatibility is often specified down to the model generation or chassis code.

Although KITACO is fundamentally a Japanese company, it has an international dimension. The company established KITACO (THAILAND) CO., LTD. in 2012, and its English-language product catalogue demonstrates an effort to make its products and compatibility information accessible outside Japan.[1] Its products are also designed for motorcycles sold internationally, and the brake-pad catalogue, for example, includes applications for European manufacturers such as Ducati, KTM, MV Agusta, and Triumph.

As of 2026, KITACO remains an active Japanese motorcycle aftermarket company with a continually updated product catalogue. The company’s website currently lists hundreds of new-product and feature entries and continues to introduce parts for both current and older motorcycles. Recent examples include security locks, brake components, wiring components, grab bars for the Monkey 125, mufflers, and engine-related parts.

This is notable because KITACO’s business model has remained relevant across several generations of motorcycles: instead of concentrating exclusively on one historic platform, it continues developing products for newer models while maintaining compatibility with established enthusiast motorcycles.

KITACO’s distinctive position can be summarised in several points:

• Japanese specialist: Its roots are in the Japanese motorcycle-parts market, and its headquarters and development history are centred in Osaka.[1]
• Broad coverage of small motorcycles: Honda Mini, Cub, Monkey, Grom, Dax, and related platforms are particularly important parts of its catalogue.
• Full modification spectrum: KITACO sells everything from inexpensive replacement hardware to serious engine, suspension, brake, and racing components.
• Application-specific engineering: Rather than simply selling generic components, many products are designed for particular chassis and engine generations, with detailed compatibility information.
• Longevity: A business that began in 1971 has spent more than five decades developing and distributing motorcycle components, giving KITACO a long history within Japan’s aftermarket motorcycle industry.[1]

Comparison with typical aftermarket brands

KITACO is best understood as a full-line Japanese motorcycle aftermarket specialist, rather than a brand focused exclusively on one category such as exhausts, suspension, or racing.

Among motorcycle enthusiasts, KITACO is particularly relevant when building or maintaining Japanese small-displacement motorcycles. Its appeal comes from the combination of Japanese-market experience, extensive model compatibility, long product history, broad parts availability, performance-oriented engineering, compatibility with popular Honda Mini/Cub platforms, and products ranging from basic maintenance to serious tuning. The brand therefore occupies a space between a traditional replacement-parts supplier and a specialist performance-tuning manufacturer.

KITACO’s official company profile lists several related companies, including KRP Co., Ltd., Tops Co., Ltd., Moto Planning Co., Ltd., and KITACO (THAILAND) CO., LTD.[1] The company itself reports a capital base of ¥25 million and 55 employees, with its primary business described as planning, development, manufacturing, and wholesale sales of motorcycle parts.[1]

KITACO can be regarded as one of the established Japanese names in the motorcycle aftermarket, particularly in the world of small-displacement and enthusiast-oriented motorcycles. Its importance is less about producing one iconic component and more about the breadth and continuity of its catalogue. Since its transition into special-parts development in 1975, the company has maintained a business centred on developing motorcycle components and adapting its catalogue to successive generations of Japanese motorcycles.[1]

In short, KITACO represents the Japanese aftermarket philosophy of detailed, model-specific motorcycle customisation: parts are developed around particular engines, chassis, and applications, while the overall catalogue spans everything from maintenance and replacement parts to performance tuning and racing-oriented equipment.
