TS 11921

TS 11921 is a service standard that sets out rules for authorized services supporting motorcycles, bicycles, tricycles, scooters, mopeds and similar two- or three-wheeled vehicles. It brings together the physical characteristics of the service facility, the technical equipment to be available, personnel qualifications, and the certification framework, so the document is about the organisation of the service operation as well as the repair activity itself.

How facility, equipment and personnel fit together

The core idea behind this kind of standard is that a service business should have enough technical capability to receive, inspect, maintain and repair the relevant vehicles in a consistent way. In general technical terms, an authorized service is an enterprise connected with a manufacturer or authorizing body and expected to maintain a defined level of knowledge, equipment and staff competence. For motorcycles and bicycles, different systems such as the frame, drivetrain, braking system, wheels and other safety-related components require different kinds of expertise, so the layout of the service and the competence of the staff are closely linked.

Vehicle groups and the certification context

• Motorcycles and similar motorised two- or three-wheel vehicles
• Bicycles and related pedal-driven vehicles
• Tricycles, scooters and mopeds with different usage characteristics
• Rules for structural features, technical equipment, personnel qualities and certification

At the time of publication, the practical purpose of the standard is to provide a minimum organisational and technical basis for service delivery. In general technical context, service quality depends on suitable tools and equipment, appropriately trained personnel, and a documented way of operating. TS 11921 defines that framework for authorized services serving the vehicle groups named in the title.
