The TR 650 Terra and TR 650 Strada are versatile dual-sport motorcycles produced between 2012 and 2013. Building on a rich heritage in off-road motorcycling, these models were developed during BMW's ownership and share components with BMW's single-cylinder lineup. The TR 650 Terra is distinguished by its spoked wheels, longer-travel suspension, and higher ground clearance, making it more suited for off-road excursions. In contrast, the TR 650 Strada features cast wheels, shorter suspension travel, and a lower seat height, prioritizing on-road comfort and agility. Both models are powered by a 652 cc liquid-cooled, single-cylinder engine delivering approximately 47 horsepower and 60 Nm of torque, paired with a 5-speed transmission and hydraulic clutch. This comprehensive Workshop Service Repair Manual (WSRM) in English provides detailed technical information for the TR 650 Terra and Strada models from 2012-2013. It covers all essential systems, including engine mechanicals, lubrication, cooling, fuel injection, ignition, transmission, clutch, brakes, electrical systems, and chassis components like suspension and frame. The manual outlines routine maintenance procedures, such as oil changes, filter replacements, and valve clearance checks, alongside in-depth troubleshooting guidance and complete repair and rebuild procedures for all major assemblies. Technical data, including torque specifications, fluid capacities, and diagnostic parameters, is also included, making it an indispensable resource for owners and technicians aiming to maintain, diagnose, and repair these motorcycles to ensure optimal performance and longevity.
