Howdy.
I lived in Osaka for over a decade, and oddly enough my best friends were Scots, Brits, and Ozzies. That threw a spanner in my slang, so I often say dodgy instead of sketchy, and too many of my sentences end with "enit?" Hanging around Japanese bikers during those years did me in a treat as well. They use both British and American biker terms quite often, and as a result I say "winkers" where a lot of other Americans say "blinkers".
For some reason, Japanese guys call a 750cc bike a "Nana-han" which means 7 1/2. lol A 883 Sportster is a "Papa-san" (because 8-8-3 can be read PA-PA-SAN). Triumphs are generally "Tora" which means "Tiger". Motorcycle and bicycle seats are always a "saddle".
I enjoy hearing slang from other countries, but here I'd like to discuss slang that pertains to motorcycles. It doesn't matter to me if you're a Brit, from Oz, or South African. If you have some English-based biker slang, please lay it on us.
I'll start with what I've seen or heard, and please tell me if it's wrong (or old)
These are British bike terms I think we Americans have heard...
"Bitsa" Bit of this, bit of that? We'd say Frankenbike. Is this still used?
"Goes like the Clappers" Fast bike. Really? Old? What's current?
"Widowmaker" really fast bike. I think we might use this here too...
"The Ton" 100mph. Everybody knows this here, but now some bikes do 200mph or more. ...2 tons? lol
"Bodger" someone who buys cheap parts to fix #$%* quick. Old? Current?
"Panniers" saddlebags... or a French bakery.
"Clock" speedometer?
"Rocker" "Ton-up boy" "Cafe racer" "leather boys" are any of these current, or all out of date?
Ozzies apparently say carbo "Carbies" for carbs, which I quite like.
Where you're from, what do you call your riding leathers? Saddlebags? Car drivers, helmets, guys who wear flip-flops and shorts on a crotch-rocket...
