FAQs

Yes. We supply sealing and elastomer-based components for motorcycle and scooter platforms, supporting both original equipment (OE) production and structured aftermarket programs.

We supply a broad range of components used across motorcycle and scooter platforms, supporting both two-stroke and four-stroke engines, as well as key engine, transmission, and vehicle systems.

Our motorcycle and scooter component scope includes:

• Oil seals and shaft seals used in engines, transmissions, and rotating assemblies
  
  
• Rubber-to-metal bonded parts and vibration control components
  
  
• Intake and air system components, including inlet pipes and intake manifolds
  
  
• Functional rubber parts, such as grommets, dampers, and sealing elements
  
  
• Engine and drive-related parts, including reed valves, chain guides, and chain tensioners
  
  
• CVT-related sealing and rubber parts used in scooter transmission systems
  
  
• Selected engineering plastic parts used alongside elastomer and bonded parts
  
  

 KOK International is a long-established Taiwanese manufacturer, with roots in motorcycle and scooter parts production dating back to 1963.

Over multiple decades, we have supplied parts used across the majority of global motorcycle and scooter OEM platforms, supporting both high-volume scooter programs and street motorcycle production. This long-term involvement has positioned us as part of the core supplier network supporting the two-wheel industry in Asia and internationally.

Yes. Our motorcycle and scooter parts are supplied into long-term OEM production programs, supporting both scooter and street motorcycle platforms produced at scale.

OEM supply requires suppliers to meet strict requirements for quality systems, process control, traceability, and production consistency. Our long-standing involvement in OEM programs reflects our ability to operate within these expectations over extended production lifecycles.

 Yes. We actively supply motorcycle and scooter parts for the aftermarket, working with established aftermarket brands, distributors, importers and system manufacturers across multiple regions.

Our aftermarket supply is typically structured around defined product ranges and long-term programs, making it straightforward for partners to source consistently and scale over time. Parts supplied for the aftermarket are produced in the same manufacturing facilities and under the same process controls as those used for long-term production programs, ensuring consistent quality and repeatability.

We understand that aftermarket ranges often include a mix of high-volume and lower-volume items. Where there is a clear program roadmap, we work with customers to accommodate this reality — including supporting range development, initial trial volumes, and phased growth as programs mature.

 Our motorcycle and scooter parts are supplied into a wide range of vehicle systems, supporting both scooters and street motorcycle platforms.

Key systems include:

• Engine systems
  (oil sealing, rotating shaft sealing, functional rubber parts)
  
  
• Transmission systems, including CVT systems for scooters
  (sealing and rubber components used in continuously variable transmissions)
  
  
• Intake and air systems
  (inlet pipes, intake manifolds, reed valves, and related rubber components)
  
  
• Suspension and damping systems
  (sealing and elastomer components used in shock absorbers and related assemblies)
  
  
• Drive and control systems
  (chain guides, chain tensioners, and associated functional parts)
  
  

 Premature failure in motorcycle and scooter parts is often caused by a combination of inappropriate material selection, inconsistent manufacturing processes, and components being used outside their intended operating conditions.

In transport-focused two-wheel applications — particularly scooters and street motorcycles used daily — parts are exposed to continuous motion, temperature variation, vibration, and environmental factors. When parts are produced without sufficient process control or lifecycle validation, these stresses can lead to early wear or failure.

 Yes. Our motorcycle and scooter components are manufactured as part of series production programs, supporting consistent quality across large volumes.

This approach is essential for both OE supply and established aftermarket distribution.

 Our motorcycle and scooter parts are manufactured within our group production network in Taiwan and mainland China, supporting both OEM and aftermarket programs.

Taiwan has long been a hub for motorcycle and scooter parts development, and our roots in the industry date back to 1963. Over time, our manufacturing footprint has expanded to include mainland China, allowing us to support large-scale production programs while maintaining consistent standards.

Across all production locations, manufacturing is governed by aligned process controls, material standards, and quality systems, ensuring that parts produced in different facilities meet the same technical and performance requirements.

 Our manufacturing model is designed for series production and long-term supply programs.

When sourcing motorcycle and scooter parts, buyers should consider whether a supplier has the experience, operational discipline, and production capability to support their requirements consistently over time.

Key factors often include:

• Familiarity with motorcycle and scooter platforms, rather than generic multi-industry supply
  
• The ability to operate within structured production programs, whether for OEM or aftermarket applications
  
• Manufacturing discipline and process control that support repeatability across batches and ranges
  
• Clear communication, accountability, and an understanding of international business expectations
