Overview

Introducing the 1961 Bultaco TSS: A Cross-Motocross Icon The 1961 Bultaco TSS stands as a legendary beacon in the world of cross-motocross motorcycles, capturing the hearts of enthusiasts with its raw power and racing pedigree. Emerging from the Spanish manufacturer Bultaco, renowned for its innovative designs and competitive spirit, the TSS was crafted for riders who sought both performance and agility on rugged terrains. With its lightweight frame and nimble handling, the TSS quickly established itself as a favorite among motocross racers, pushing the limits of what a 125cc bike could achieve. Engine Performance and Riding Characteristics At the heart of the TSS lies a spirited single-cylinder, two-stroke engine with a displacement of 125cc, delivering an impressive compression ratio of 13.5:1. This powerplant, fed by a precise carburettor, offers exhilarating acceleration and responsiveness, making it a joy to ride on both trails and tracks. The TSS’s wet multiplate clutch and chain final drive ensure smooth power transfer, allowing for seamless gear changes and a connected feel with the bike. Riders will appreciate the TSS's lightweight design, which translates to agile handling and the ability to tackle sharp turns and jumps with confidence, embodying the essence of motocross racing. Key Features and Technology The TSS is built on a sturdy tubular frame that not only enhances durability but also contributes to its lightweight disposition, a crucial factor for competitive riders. The bike is equipped with expanding drum brakes at both the front and rear, providing reliable stopping power essential for negotiating the unpredictable terrain of motocross. Additionally, the telescopic front suspension plays a pivotal role in absorbing shocks and ensuring stability during high-speed maneuvers, further solidifying the TSS’s reputation as a formidable competitor in its class. This combination of engineering and design results in a motorcycle that is both fun to ride and highly capable on various surfaces. **
