Sisu Avolavakuorma-auto (BA) – the Finnish register class of Sisu flatbed trucks: six- and eight-cylinders of 5.2 to 15.9 litres, 59 to 405 kW, unladen weight 3,050 to 17,350 kg
This page gathers the Sisu trucks of the Finnish registration class Avolavakuorma-auto (BA), that is, flatbed trucks with an open load platform, as kept by the Finnish vehicle register Traficom. As the register here records engine capacity above all as the distinguishing feature, the model names carry the respective engine size in cubic centimetres, in some cases with the added suffix 2ov for the second axle variant. Sisu, the Finnish truck maker with roots in the state group Sisu-Yhtymä, built its vehicles on its own chassis with six- and eight-cylinder diesel engines.

The register lists here 14 versions with 59 to 405 kW from six- to eight-cylinders of 5,240 to 15,928 cm³, unladen weights from 3,050 to 17,350 kg, gross weights from 6,500 to 50,000 kg, lengths from 6,100 to 10,000 mm and widths from 2,300 to 2,600 mm.
Flatbed trucks of this kind formed the backbone of construction and timber haulage in Finland for decades, where Sisu, with chassis and engines tuned to Nordic weather and road conditions, ranked among the preferred domestic makes alongside the international manufacturers.
On used examples, rust on the frame and platform, the condition of the engine, clutch and gearbox, the tightness of the hydraulics on tipping platforms, and the condition of the axles and brake system on the heaviest versions all count; parts run through Sisu authorised workshops in Finland and the Nordic commercial-vehicle parts trade.
