Guys,


I'm about to change my rear sprocket but I have a huge problem. I am under the impression that my rear wheel is the original for mc18 r5k which is 18"., but I'm surprised that it is 17" inch rear wheel. It's probably good news on tire selection but I don't know gat sprocket to buy.. The parts manual for MC18 r5k will be useless since its a different rear wheel. I don't know what bike the wheel came from but its look exactly the same as the original in the mc18 pictures, is also has 6 spokes. I don't know what bike it came from.. could it be from the mc21 or the mc22 (CBR)? the sprocket that came with the bike is a TALON 42T-520. any suggestion on what bike the wheel came from?

Thanks.
