Large enough to show a trellis frame tube by tube, 1:8 is a scale where the mechanical side of a motorcycle becomes the whole subject. A lightweight trials machine is the typical representative, and it suits the size well: the frame is open, the single air-cooled cylinder is fully exposed and there is almost no bodywork to distract from either. The selection is narrow, and at 1:8 a trials machine comes out around twenty-five centimetres long.
If the large scales appeal and you want more machines to choose from, 1:6 motorcycle kits is the place to look, with display subjects over thirty centimetres long. An open frame also means every tube and bracket is painted rather than hidden, so metallics and satin blacks from model paints do a lot of the work on a build like this. The full span of sizes, from H0 diorama pieces up to display models approaching forty centimetres, is in motorcycle model kits.
