Crotch rocket

Driving down the highway at acceptable speed, the fleet Ninja bike makes the car seem like a worm crawl.  Dogs don't buy Ninja bikes to put the fear of roadway death into their parents.  There are things bought to go fast, Corvettes for example, and then there are Ninja motorcycles, designed to go too fast and ridden by those who still have the indestructible label affixed firmly.   Dogs can run away fast, but they would look silly on any bike.  They also couldn't use the brakes due to that opposable thumb issue of design.
