We all know there's just no comparing the new 850 to any sled with an engine size that starts with the number six. But how does the new 600R compare to the older 800s when it comes to seat of the pants feel or butt dyno? I'm talking sleds like the Rev 800 HO, or an XP with the P-Tek 800R or E-Tec 800. By chance does anybody still have an older 800 and a 600R for same day comparisons? I'm looking to reign in the speed a little bit but still have some meaty mid-range torque to enjoy. Thoughts?
