Hi all, Just put Supermoto tires and wheels on my 2004 DRZ400S. Front is a 120/70R17 and the rear is a 160/60R17. The tires are Avon Distanzias and the chain is very close to the rear wheel, actually a lot closer than I would like (almost rubbing). I plan on getting the rear wheel off-set, once I can find someone that is capable of doing the work here in Northern CA. I have noticed that the swing arm chain buffer and guide on the SM models are different. The front chain buffer is obviously different and the rear chain guide near the sprocket also has a different OEM part number. Has anyone ever installed the SM chain buffer and guide on the S model? Is it recommended?
