I voted for tool, hehe. I never use gender to describe my vehicles, just like I dont have a name for my cock!! ....too weird, but if i were to describe it I'd say it was a big strong fast animal of some kind that couldn't be tamed but just had to be ridden !!
I always thought my Buell looked like a Bull, with it's huge 'shoulders' and slim rear end, like it was charging forth. The KTM.....not sure yet, it hasn't hit me with an obvious likeness yet.
I suppose with the hints of orange it could a bit tiger-like (?) but maybe some other wild cat would be better?
I see this is an important issue for you , since it's posted in technical........
