Sisu L-137 – the Finnish heavy truck with CIT, EIT and SVT chassis codes: six-cylinder engines from 121 to 140 kW, gross weights from 16 to 17.5 tonnes, lengths up to 8.4 metres
Sisu is a Finnish truck manufacturer whose L range counts among the heavy cab-over lorries for the Nordic market; the L-137 forms its own range within it with several chassis variants. The model names carry letter codes such as CIT, EIT, CVT and SVT, plus numeric suffixes such as 4300, 4600 or 4800, all listed in the register as distinct chassis designations.

The register lists here 10 versions with 121 to 140 kW from six-cylinder engines of 6,540 to 6,600 cm³ displacement, unladen weights from 6,900 to 10,950 kg, gross weights from 16,000 to 17,500 kg, lengths from 7,050 to 8,400 mm and widths from 2,420 to 2,600 mm.
Sisu trucks are known for their ruggedness in Nordic winter operation and were traditionally used for forestry, construction and military purposes in Finland; the L-137 belongs to the generation of heavy two- and three-axle chassis that, alongside imported marques such as Volvo and Scania, helped shape the Finnish market; such chassis typically carried tipper, flatbed and municipal bodies for construction and forestry work across the country.
When buying used, on these chassis check corrosion on the frame and axle suspension after decades of winter use with road salt, the condition of clutch and gearbox under heavy loads, the tightness of the brake system, and the availability of spare parts; for this rather rare marque these mainly run through Finnish Sisu specialists.
