yes, but the gear ratio will be very low. when you pedal you will need to do more rotations with your legs to travel the same distance as with a 33 tooth and 13 tooth.
BMX stands for Bicycle moto-cross, because of the stunts performed on them. Most BMX bikes have 20 inch wheels with a 25-30 tooth front sprocket, that way you easily pedal fast and up steepembankment, like a half pipe or ramp. BMX bikes are easilymaneuverable and agile. Most are made from light-weight aluminum, weighing around 20-25 pounds. There are many great BMX companies, but one of the most popular companies is "Wethepeople".
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.
no you can not 25 with 8
around 25 lbs or so.
You can get a 9 tooth sprocket, you will need a conversion kit to do it. Haro makes a decent one just do a search for Haro 25/9
9 tooth driver
It depends on the length of the chainstays on your frame.
a 25 tooth sprocket will fit on a 9 tooth driver
a 9 will do but an 8 would be better
A fang tooth lives for approximately 15 to 25 years although the oldest fang tooth lived up to 32 but the average is 15-25
25 goes into 25 one time.
