Sisu R-142 – the collective page of the Finnish Sisu truck type in the register: six-cylinder diesel of 11,100 to 14,000 cm³, 183 to 276 kW, gross weight of 22 tonnes
This page gathers the Sisu R-142 – heavy trucks from the Finnish maker Sisu of Karis (Karjaa) in southern Finland. The type designation R-142 follows the maker's own system; the suffixes in the model names such as BPT, CST, CEV-LAV or DET-6X2 denote different chassis, axle and drivetrain versions of the same base type, with the digit combinations after them giving frame lengths and wheelbases.

The register lists here 10 versions with 183 to 276 kW from six-cylinders of 11,100 to 14,000 cm³, unladen weights from 8,550 to 13,300 kg, a gross weight of 22,000 kg, lengths from 8,100 to 9,550 mm and widths from 2,400 to 2,550 mm.
With a gross weight of 22 tonnes and large-capacity six-cylinder diesels, the R-142 ranks among the heavy class of Finnish construction, long-haul and forestry trucks that Sisu built for decades for customers outside the large-volume makers. The range of axle and body variants shows use from flatbed through tipper to tanker, and the R-142's presence in this weight class put it in direct competition with the volume makers on Sisu's home market.
On a used example, the condition and mileage of the six-cylinder diesel, wear on clutch, gearbox and brakes at this weight, the condition of frame and body, and corrosion on cab and mudguards all matter. Drivetrain and chassis parts run through the Finnish Sisu service network, body parts through the respective body builders.
