Where 916 fits
Why 916 is special
Its underseat exhausts and single-sided swingarm were adopted so widely that a design intended to be distinctive became the template.

Roman numerals
C M X V I
CMXVI uses the subtractive pair CM: a hundred before a thousand — a thousand minus a hundred.
Binary

1 × 512 + 1 × 256 + 1 × 128 + 0 × 64 + 0 × 32 + 1 × 16 + 0 × 8 + 1 × 4 + 0 × 2 + 0 × 1 = 916

1 × 512 + 6 × 64 + 2 × 8 + 4 × 1 = 916
Hexadecimal
3 9 4
3 × 256 + 9 × 16 + 4 × 1 = 916
Read as powers of two: 512 + 256 + 128 + 16 + 4 = 916.
In historical numeral systems
Egyptian
9 coils of rope, 1 hobble, 6 strokes
9 × 100 + 1 × 10 + 6 × 1 = 916. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 5 vertical wedges (sixties place), 1 corner wedge + 6 vertical wedges (units place)
15 × 60 + 16 = 916. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sampi, then iota, then stigma, marked as a numeral
sampi-iota-stigma + keraia
sampi + iota + stigma written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then tav, then qof, then tet, then zayin
tav-tav-qof-tet-zayin
The ordinary rule would give יו (yod 10 + vav 6), also a divine-name form, so 16 is written טז — tet (9) + zayin (7).
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
