I am still saving my money for the bike I have been wanting for a while - a big bore XR. I was originally leaning toward a 1992 - 1999 XR600 (I am steering clear of liquid cooling ), and I was going to set it up for dual sport to hit some of the trails from my garage. I have read a lot on the XR600's, and they seem bulletproof. But I have been intrigued by what seems to be a lot of XR650L's for sale lately. There is a reallly sharp one on ebay now, and the price seems decent, and it has a lot of aftermarket stuff on it. I understand there is about a 50 pound difference between the 650L and 600R (the L is heavier). Where does this weight come from? What are the differences in the bikes? Is the suspension different? Fork tube size, wheel travel, etc.?? Does the rear rubber mounted hub make for a smoother ride on the road? Can this rubber mount be installed on a XR600? I am estimating I'll be doing 50% riding on road(which will include fireroad riding)and 50% off road, including single track riding (my favorite type of riding, which I savor with my KTM 300 EXC). Does anyone have any experience on both bikes? Pros/cons? I have had a few guys tell me they absolutely love their 650L's, but they are heavier than the allready heavy 600 R. But I have seen some great dual sported XR600's, so I'm caught on the fence. Even though the 600/650 is heavy, I don't want the 400, as I know it won't handle freeway speeds. I want torque and power. Any and all input is appreciated.
