Does any one know for about how much will it cost me to change rear wheel...
 

...of my bike ?? bike is XCD !!!

if its like a mountain bike or bmxlike 50$ tops a dirt bike or chopper it can go up to 300$

Depends if you want new,or if you can deal with used. My dad just replaced the rear wheel on his wide glide, he knew exactly what he wanted, and found it on ebay for I believe like $150 or so. It has a few imperfections, but we know where we can take it to get it buffed out, and its still ALOT cheaper then getting it brand new. Just check things like ebay, motorcycle magazines, motorcycle trader, and believe it or not motorcycle shops will sometimes let people list the parts they are selling on a cork board or something.

Another bike..?
