If you've worked on both bikes and cars, then you already know that one significant pro of taking apart bikes is that they are, generally speaking, a whole lot smaller. In many ways, that makes it both easier and more practical to start wrenching on a bike than a car (assuming neither is super modern and you can still work on them yourself, of course). Parts you pull off take up less space, you don't usually need an entire engine hoist, and so on.
But what if you could have your own Kawasaki Ninja H2R, and it was even smaller? And what if I told you it would only set you back a cool US $119?
You'd probably look at me like I'd lost my mind, that's what. (Plot twist: Maybe I have!)
