I have owned a few XR's in the early 80's and 1 XL. I want a new dual-sport bike to ride to and from work at times, and in the future some long distance dual-sport rides. I am considering the XR,XRL, and the DR as rides. I like the XRL and DR due to the simplicity and reliability of the air cooled engines. The KLR is out due to its size and not being as capable off-road as the others. Hows the reliability of the XR and XL engine over time? What are the known problems and fixes? Show me some pics of your XR bikes you have modded with larger tanks and lighting kits? Thanks in advance for any info, im just weighing my options on all bikes.
