The Sisu DK12M K-KK-6x4 of 2011 is the only three-axle representative of the DK12M series in the dataset and therefore carries the configuration with six wheel positions of which four are driven. Two driven rear axles give the vehicle traction on loose ground and make it the classic construction-site and timber truck.
The six-cylinder engine delivers 350 kW from 11,946 cm³ displacement. The length of 9,460 mm and the width of 2,500 mm are compact, the slim body of 2,500 mm helping on narrow forest tracks and building sites. The kerb weight is 9,980 kg. The dataset gives no permissible gross weight; for three-axle trucks of this kind it usually lies within the legal maximum values, but the exact figure must be taken from the vehicle papers.
The light kerb weight for a truck of 350 kW shows that the chassis was meant for bodies that are fitted only afterwards, such as a tipper, crane or tractor body.
Sisu DK12M – the 12M variant of the Finnish DK range: a single six-cylinder engine at 350 kW from 11.9 litres, axle configurations from 6x4 to 10x4, gross weights up to 51 tonnes
The DK12M designation marks off the 12M power class within Sisu's DK range, while the parallel DK16M class carries a stronger engine. As across the whole DK range, the letter strings K, A and P denote axle types and cab configuration, the figures 6x4, 8x4 or 10x4 give wheel count and driven axles, and the following plus-linked numbers state axle spacing in centimetres; the number of configurations reflects the wide range of bodies offered for timber haulage and special transport.

The register lists 14 versions, all with the same six-cylinder engine at 350 kW from 11,946 cm³, kerb weights from 9,980 to 27,000 kg, gross vehicle weights from 36,500 to 51,000 kg, lengths from 8,740 to 13,500 mm and widths from 2,500 to 2,800 mm.
DK12M chassis form the base for crane, container and tipper bodies in Finnish and Scandinavian construction and forestry traffic; the single engine paired with widely varying axle counts and body lengths shows that Sisu matches the power class to payload through the number of driven axles rather than through the engine.
When buying used, as across the DK range, check the condition of crane and tipper bodies, axle differentials on multi-axle versions, frame condition after off-road use, and corrosion of brake lines; with the engine standardised, it is also worth comparing mileage across the different axle configurations. Parts are available through Sisu's authorised workshops in Finland and Scandinavia.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
