Yamaha
Japanese manufacturer of the snow-bikes ridden by Locque's men in Cortina. As well as having spiked tyres for grip on snow and ice, the bikes also have small machine-guns concealed inside the front indicators - not a standard factory option. (FYEO)

Yogurt
Part of Bond's breakfast for one. (FRWL)

Yoyo
Normally an inoffensive toy, one of Kamal Khan's hired thugs (for once the term is entirely accurate!) has a specially-made version consisting of two steel circular saw blades. The weapon sees off the unfortunate Vijay, and very nearly gets Bond too - a drop of water, from its recent passage through the lake around Octopussy's palace, alerts him moments before the deadly device is unleashed. Its user, unlike many of Bond's gadget-toting enemies, doesn't die a horrible death from his own weapon, but he is at least eaten by a crocodile instead. (OP)

Yukon
A part of Canada where the 747 that had been carrying the Moonraker space shuttle crashed. The exact co-ordinates were 136 degrees 15 minutes 10 seconds West, 63 degrees 20 minutes 48 seconds North. (MR)
