Hi all I currently ride a 90 XR600R. It is stock, jetted well with an opened airbox. I Ride it dual sport running 15/48 gears with Kenda Trackmasters. I ride back roads/trails and some single track and off road stuff. Not afraid of the weight or power thing! I haven't the opportunity to ride a XR650L or a XR650R but am interested in upgrading for more power and better suspension modern features. Is the XR650L significantly more powerful than my XR600R? I know the XR650R will be, especially uncorked but how much more? I would be looking for more hp for road and higher speed off road stuff. I guess what I am looking for is whether the XR650L is a sufficient upgrade from my XR600R or should I pony up for a XR650R? I would have to find a blue plated one as it is getting to be a bitch to plate off road bikes now. All experience/opinions welcome please.
