new to all this stuff... i just wanna know whats up with all the letters that are on the end of the model such as ZXR250A or ZXR250C. im thinkin of getting a ZXR but dunno what all the "A" and "C" means (dunno if there are more letters, thats all i seen so far!!) and what difference it makes and how you can actually distinguish the difference....??? as much help would be greatly appreciated... im think of getting one and need to absorb as much info as i can...
