If I had to pick something motorcycle related based on his looks, I'd name him "sprocket". There's a girl who works at my vet's office who rides, and she has two dogs, Ducati and Enzo. Other cool dog names: Deacon, Grizz, Griff, Graff, Doug, Murphy... Etc. Just start playing with him a lot, and generally his playfulness will help you land on a name. My dog's name is Bear (I adopted him at 2, and it just didn't seem right to change it at that point), but I call him "Bud" or "Buddy" so much that one day, I grabbed his leash and said: "C'mon Buddles!" My GF and I cracked up for like 10min, so that's his new nickname.
