My wife´s S50 Suzuki 2006 has the same problem. Just replaced the front pads and the breaks screech huge. Is there a treatment to put on the rotar to reduce the screech or possibly some other fix. No other complaints with the bike. It´s a perfect run-about bike for my wife who is short yet wants the power of a bigger bike. The S50 meets this objective great. Need help with the SCREECH. Thnx.
