I picked up the first XL 600R from my local dealer back in 1983. Such a step forward from the 1981 Yamaha XT 500G it replaced. When this bike came out I thought the "enduro" market segment might actually get some new MX technology injected into new enduro/dual sport bikes...no such luck. Other than a rear disc brake my 2004 DR 650 has no new technology from what you see here. The XL was at least a hemi with dual/two stage carbs.
