Sisu – other trucks: the collective page of Finnish trucks outside the named ranges, from the K and KB types to the L-131 and L-139, 47 to 408 kW, Sisu's own and bought-in diesel engines of 3.0 to 15.2 litres
This page gathers Sisu trucks the register could not assign to a named range – mostly older cab-over K and KB types and the L-131 and L-139 ranges of the 1970s, some models also carrying nicknames such as Kärppä-Sisu (ermine) or Karhu-Sisu (bear). Sisu, the Finnish truck maker with plants including Karjaa and, historically, Karhula, has built sturdy trucks suited to Finland's climate and infrastructure since the 1930s; the K in the type designation, by the maker's logic, stands for the cab-over cab (Finnish 'kaappiohjaamo'), the following number for the power or tonnage class, SVT, CVT and CIT for different cab and drivetrain variants.

The register lists here 174 versions with 47 to 408 kW from four- to eight-cylinders of 2,980 to 15,200 cm³, unladen weights from 2,300 to 18,500 kg, lengths from 5,000 to 11,930 mm and widths from 1,850 to 3,200 mm.
Sisu is Finland's most important truck maker and, besides civilian road transport, traditionally also supplies the Finnish military and forestry with off-road, winter-hardy vehicles; the marque has thereby held its own for decades alongside the big Scandinavian makers Volvo and Scania.
On the older K and KB types, corrosion on the frame and cab, the condition of the engine, clutch and gearbox, and the availability of spare parts, largely confined to Finland for these rarely exported models, count; on all-wheel-drive forestry and off-road versions, the transfer case, axles and tyres as well.
