Okay, let's start a word game with words that relate to motorcycles that follow the alphabet. I will start with the letter "A" - Axle

B - bike

C - Chassis

D - Ducati

If you are doing to say Ducati for "D" than you might as well go with "Ducati desmodromic".

We're taking turns? E is for Excelsior!

(A classic American brand from the first decades of the 20th century)

Fatboy Harley

You may want to turn this around and start over again once we've done 26, but there's bound to be more "A"s and a couple of old brands that I doubt anyone else will think of just popped into my head.

Allstate - A buddy had a 100 cc (I think) from this brand that was distributed by Sears in the 60s (maybe earlier too.

Aermacchi - How about a little side action? Why should this brand be known to enthusiasts in the U.S.?

AAArghhhh!

Sorry, I can't wait. I'll try to include only the most arcane names/words that I can think of.

Aprilia, Bimota, Cagiva, damn - too bad I used desmo above - Drag racing, Elefant (a Cagiva model), Fast by Gast, Greeves, Husqvarna, ISDE (side action on what it stands for), Jawa, KTM, Laverda, Moto Morini, Nitrous injection (oh baby let's go fast), Oh baby let's go fast, Pope (I have a very cool Pope sales card from c. 1910), "q" is a tough one - maybe we ought to see who gets it in a "Qualifier" HA!, Royal Enfield, Shift fork, Twist of the wrist, Under-powered (aka Harley Davidson HA!), Velocette, Wrist pin, X-box - what you play with while you're waiting for a broken leg to heal, Zundapp.

Ahhhh. Sorry - it was eating away at me.

C'mon people, I'll do the whole alphabet again if nobody else will get in the game.
