Sisu R-142BPT-6X2 – Finnish trucks with 6x2 wheel formula: six-cylinder of 11.1 litres displacement, 161 to 195 kW, 10 to 21.75 t unladen weight, 22 to 26 t gross weight
Sisu R-142BPT-6X2 is a range from the Finnish manufacturer Sisu, based in Karis (Karjaa), with the 6x2 wheel formula, meaning six wheels of which two are driven. The brand name Sisu, used in Finland for commercial vehicles since 1931, means roughly perseverance in Finnish and stands programmatically for the vehicles' construction, built for harsh Nordic operating conditions. The vehicles recorded here uniformly carry the six-cylinder engine of 11.1 litres displacement, an engine common in heavy Sisu trucks.

The register lists here 7 versions with 161 to 195 kW from six-cylinders of 11,100 cm³, unladen weights from 10,000 to 21,750 kg, gross weights from 22,000 to 26,000 kg, lengths from 7,700 to 14,700 mm and a width of 2,500 mm.
The 6x2 wheel formula, with one drive axle and one steered trailing axle, is common among heavy trucks in Finnish road and distribution traffic, since it allows a high permitted axle load with less wear on the trailing axle; Sisu is represented in Finland with this range alongside Scania and Volvo. Unlike the large-series manufacturers, Sisu builds its trucks in smaller numbers and largely to individual customer specification, which explains the large number of different equipment and body variants within a single range.
On used R-142BPT-6X2-range trucks, engine operating hours, the condition of the drive axle and trailing axle, rust on the frame and body mounting beams, and brake and tyre condition appropriate to the axle load count; spare parts run through the Sisu service network.
