Both Eatern and Haro buys their sprocket from other manufacturers, and the sprockets don't really care what bike they're put on. However, there are two different types of BMX hubs, and sprockets can only be moved between hubs of the same type.
At the rear they're called sprockets(unless you speak BMX, then they're called drivers), at the front they're called chainrings, or chainwheels(unless you speak BMX, where they might be called sprockets)
Because they have small wheels. To get any speed out of a BMX they have to have small sprockets. It's all about ratios.
The BMX bikes that you buy at Target and or Walmart are not the same BMX bikes that are used in BMX Racing and BMX Freestyle. Real BMX bikes are lighter, they have diiferent size sprockets among many other things. Feel free to google the National Bicycle League or the American Bicycle League to get more information.
Yes all parts are except for the stems and sprockets witch are anodized. I perfer you get one.
If you have a "normal" bike (whatever you mean by that), and want to do BMX style riding, then sure, get a BMX instead. But if you're not interested in tricks, stunts and jumps, then a "normal" bike will probable be more useful to you.
A chain is a chain, it hasn't got any gears in it. But if you run it across a pair of sprockets you can create a gearing ratio.
yes it will, they are the same bikes exept for some few details and the engine, you would also need to swap the chain and sprockets
Throat Sprockets was created in 1994.
Sprockets are the toothed wheels that the chain run over.
The only thing that I can think of is chainwheels for BMX, or bikes with Ashtabula cranks. These are sometimes called sprockets and can have different diameters for the center mounting hole. The bore would then have to match the axle of your crank for you to be able to use that chainwheel.
It drives the rear wheel. Used on newer/more expensive bikes instead of a freewheel.
