i was wondering if i had to change my brakes and suspension if i was to get the KMC BACKSEAT SERIES 125 22"....thanks

 

You don't have to change your suspension, you should however upgrade your brakes. I guess you could get by with the stock brakes, but it's not really safe. Every time you go to apply pressure to the brake pedal you're going to feel like nothing is happening, so then you press harder; then finaly the vehicle starts slowing down(very sluggishly). This could be dangerous. I don't know what your driving style is, but if you drive anything like my wife.....*cringe*
