Long time lurker, first time poster! No where near my first bike, but def. my newest bike. I've had my 08' 400-SM for about a year now, and bought it for a fun, city-bike to drive back and forth to work/play. Well, I'm looking to transition into more dirt riding with it now. I had a street-legal Yamaha TTR250 years back, and did alot of dual-sporting/long rides/camping trips with it. Looking to set my SM up the same. My biggest thing is the wheel/tire situation. I'm (idealy) looking for a second set of dirt rims, as I have a brand-new set of tires for 18/21's All I've been able to find are new sets for $1000+ Not really wanting to drop $1000+ on some dirt rims. And everytime I catch some on ebay, it's when I've not a penny to spare (of course, LOL). Now, I'm not opposed to the ideas of: 1) Picking up a set of 17'' dual-sport tires from http://www.procycle.us/bikepages/drz400.html#wheels Though, I'm not sure how they perform.. 2) Trading my SM wheels for some S (or E?) wheels. But I'd imagine I'd have to relocate the calipers? What about the gear-ratio? Are they pretty close? For off-road, I'd like to get something a little lower-geared. Anyways.. I've browsed the forums, and I've only been able to find little snips and pieces here and there.. Only people looking to convert TO an SM model, not the other-way around. I'm going to keep searching, but if there is anything else that I should be aware of, I'd greatly appreciate it! Also, I'm in the Dallas area, so if any other DRZ guys out this way, give a hollar! Thanks!
