MOTORCYCLE CLASSES

rake, trail, wheelbase and seat height — six classes drawn at one scale

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

Formats: A4 · A3 · A2
What you get: Print-ready PDFs, one per size, with every letterform converted to outlines — nothing to install, nothing to shift.
Subject: vehicles · everyone · comparison · study

Figures from the makers’ own specification pages: Yamaha, Harley-Davidson, Honda. Inches and pounds converted here. Wheels, spacing, fork angle and seat height are drawn from them; the frame line is schematic.

THE SAME FORK CARRIES TWO DIFFERENT NUMBERS

BMW lists the R 1300 GS with a steering head angle of 63.8°. Yamaha lists the R1 at 24.0°. Geometrically these are not different worlds — they are different datums: the Germans measure from the horizontal, the Japanese and Americans from the vertical, and the two always add up to 90°.

That same GS in the Japanese system would read 26.2°, which puts it exactly between the enduro and the adventure bike, where it belongs. So a spec sheet saying 63.8° is not describing a chopper: turn the datum around.

On the sheet

Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
Nothing about how it was made: the sheet carries only what the reader needs.

Printing

Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
White background and sparing fills — it prints on a home printer without draining the cartridge.
Margins of at least 10 mm: a home printer cannot print to the edge.
No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 4 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
