Sisu CK16M – the collective page of Finnish heavy-duty trucks with an engine of about 16 litres, three- to five-axle tippers and tractor units for forestry and mining use, 380 to 460 kW
This page gathers the versions of the Sisu CK16M, a heavy multi-axle truck range from the Finnish maker Sisu Auto. Sisu, active as an independent Finnish truck maker since 1931 and at times linked over the decades with Leyland and Saab-Scania, specialises in rugged chassis engineered for the Nordic winter and heavy terrain. The designation CK16 refers to the range's six-cylinder engine of about 16 litres (15,569 cm³ displacement), M denotes a model generation; the type codes in the register such as K-AKK, KA-KK or KA-KKA behind the axle formula (6X4, 6X6, 8X4, 10X4) mark the arrangement of driven, steered and trailing axles. The number sequences after the slash give body or axle loads in kilograms.

The register lists here 57 versions with, throughout, six cylinders and 15,569 cm³ displacement, 380 to 460 kW output, unladen weights from 11,510 to 35,450 kg, gross weights from 29,000 to 55,450 kg, lengths from 7,115 to 13,550 mm and widths from 2,500 to 2,790 mm.
The CK16M range is widespread in Finland above all in timber haulage, mining and heavy transport, where the four- and five-axle chassis with trailer make full use of Finnish permitted gross combination weights well above 60 tonnes; Sisu chassis compete there directly with Scania, Volvo and MAN.
On used trucks, operating hours and the six-cylinder engine's service history, condition of the transfer case and axle differentials, frame and articulation on multi-axle chassis, brakes and crane mounting on versions with a loading crane count; parts run through Sisu's service network in Finland.
