Hello, I'm looking to get some DRZ 400e/s dirt tires to convert my DRZ 400sm for dirt riding. My question: can I use any year DRZ 400e/s dirt tire for my 2009 DRZ sm? I have read many links that the e/s tire will go right on the SM and the only modifications are using the SM calibers/spacers. My main question is regaurding the front tire speedo- what year 400 e/s tire will be compatible for speedo hook up? FYI-I'm looking at a set of 2005 400e to put on my 2009 sm. thanks!
