B.dropped at 5 mph w/minor damage to the street fairings
C. 1st 848 owner... not sure which type of oil to use, what type of chain lube to use and not sure how many miles can I get with the reserve light.
I'm sure if you had 2 848's, same mileage; one that never saw the track vs one that was on the track for 1 yr but had all the oem stuff removed (plastics, headlights, harness, clip ons, rear sets, exhaust) then replaced before it went up for sale, you probably wouldn't even notice the difference.
My gig is that it all depends on the owner. If you don't know the owner, you don't know the history of the bike.
The owner could have probably swapped out the gauge with one that has lower mileage, crashed the bike but fixed it and never told you.
The owner could have bought the bike brand new, only rode it on the track but at a B or C group pace and changed the oil after every other track day.
