a 25 tooth sprocket will fit on a 9 tooth driver
No. a 9T sprocket will only fit a cassette hub, and not freewheel hubs.
Not a sprocket only, but you can buy a 23-tooth freewheel that should fit.
22 or 23 tooth sprocket will work. 23 will give you more top end speed for cranking at those huge gaps, while 22 will give you easier acceleration.
The recommended size of the chain to use with a small sprocket is typically a smaller chain size to ensure proper fit and function.
No way of telling as it'd depend also on the size of the frame. For all "normal" applications chains a sold a tad longer than needed, and are cut to length on assembly on bike.
Yes Pretty much all 3 piece cranks should fit any sprocket you buy for them.
Yes...this is the most comon gear ratio on bmx's. this is because it allows a good balance of accelration and top speed while still giving you the clearance to be able to roll into most quarter pipes.
It will if you have bmx (or bmx style) cranks.
