Name for a new horse??? *Please?*?

I'm getting a new horse tomorrow and i've been searching for a new name for him for the past couple of months but so far i haven't found anything that really fits him perfectly. He's a 17.2 dark bay 6 yr old ex-racehorse gelding. I'd like an uncommon, unique name, one that speaks of masculinity but also gentleness and softness. So a name that would fit a strong silent type. One worded names though please, he already has a registered name (his racing name) but i don't want his name to be related to that one at all.
