Sorta kinda. Engine wise depends. If you look at Brian Brave's it looks like a carburetor 1 piston 2 stroke. My bike has a inline 4 4 stroke also carbuerated. There are different types of engines. V twins are usually most common on cruisers and Harleys. sport bikes usually have inline 4 cylinders (sorta like many smaller cars), there are even 3 cylinders like Triumphs. BMW like's to expirement with boxer engines so you have horizontally oposed 2 cylinder engines. You can have a single cylinder also. And yes, there are even 6 clyinder bikes (Honda Valkyrie for example). Majority of modern cars are fuel injection though and not carb. Carburaters work based on mechanical parts and IMO are simpler to work on than an engine loaded with electronics. The crankshaft is what the pistons spin on. And that eventually is connected to either a drive shaft (mostly big cruisers), a belt (also cruisers), or a chain (usually sport bikes and endurance).
