About this generation
The Sisu S-Series was introduced in 1980 as a new modular heavy-duty truck range designed for road transport, construction, forestry and demanding vocational applications. Its modular cab architecture allowed Sisu to offer low and high forward-control configurations as well as conventional-cab trucks on a common platform. The range included SK, SM, SL, SN and later SR models, with multiple axle configurations and engines supplied by Valmet and Cummins.
