About this generation
The Sisu R-Series was introduced in 1970 as part of Sisu's new heavy-duty Jyry truck range. Designed for demanding Nordic transport, logging, construction and vocational applications, the R-Series combined a robust conventional cab chassis with a wide range of axle configurations and diesel engines from Leyland, Rolls-Royce and Cummins. The series included 4x2, 6x2, 6x4, 4x4, 4x4+2 and 6x6 configurations and remained in production into the early 1980s.
