XR250L and R claimed weight (it varies a little by year) is ~239 lbs dry. XT225 claimed weight is 238 lbs dry/267 lbs wet. DRZ400S claimed weight is 291 lbs dry/319 lbs wet. Feels like a lot more when it falls over. I wouldn't say any adult bike is "so much lighter" than an XT. A few may be a little lighter, but outside of Beta, I don't know of any that are. The XT225 is a great, lightweight trail bike. Unlike the XR it has e-start and a low seat height. The XT overcomes a lack of power with 6 speeds. I've stalled out my DRZ more than I have the XT. It also gets significantly better gas mileage than the DRZ. Stock tanks are about the same size, so in stock configuration, the XT has about 50% further range. Picking up the XT on an off-camber slope is substantially easier than the DRZ. In the last couple years my XT has done the WABDR, the NW Passage ADV Route, been to the Alvord Desert including a bit of sand riding, and my youngest son and I are planning a 150 mile round-trip dirt ride in Eastern WA in a month or so (he'll be riding the XT). Great bike.
