Pretty sure it's the case with my "new" used bike, but why? It is my estimation the bike has the instrument cluster of a Yamaha FZ6R (newer model) although it is a 2007 FZ6. I noticed this as it has a 2000rpm lower redline at 12,000rpm, while the 2007 FZ6 redlines at 14,000rpm. I did not notice when I bought the bike as I am new to motorcycles and was not focused on the redline / tachometer. First thing to mind is odometer fraud. Yet the bike shows little sign of wear, has its original rubber (soon changed), and looks and seems very much a 7,000 mile bike as claimed. In fact it looks much like new and runs flawlessly as one would expect of a low mileage bike. Has a few minor cosmetic scrapes but shows no signs of abuse or the sort of wear that comes from many thousands of hard run miles or exposure. So, what gives? Checked out fine with the DMV and insurance company and has a clean title. I have no intention of pursuing this with the seller, really. I like the bike and paid just $3,000 for it. And I really have no idea what I'd be pursuing but a shallow lawsuit, and a misdemeanor for odo fraud. If that. And he is not the original owner and could just claim the bike is "as is" being his title is clean. So, what we have here is a mystery wrapped in an enigma. Why 'o why does my FZ6 redline like a FZ6R? Which is my next thing to ponder. I read these things were high tech, fed by sensors and ECU's and all? Everything on the instrument cluster functions right. Fuel, temp, speedo. Its all digital. The tach functions perfectly, the bike screams appropriately as the needle rises. I have not gone to redline yet but 9,000rpm would seem very much 9,000 rpm. Would an FZ6R engine fit in the frame of a FZ6 if rebuilding a bike? But why not just rebuild a FZ6R if doing that? It would fetch more money. I am not a thief, however. So cannot think like one. So I really don't know. I even researched to see if the bike had a lower redline because of Cali emission standards, or maybe it came from overseas? But that would not seem the case. Those bikes seem all the same as any other 2007 Yamaha FZ6 S2's with....14,000rpm redlines!! So, what gives? Could it have all been innocent? Someone whose cluster failed and was replaced by the wrong one? But would it even work without some "know how" going into it? If this bike wasn't so perfect in several hundred miles of riding the last couple of weeks or was falling apart and seeming OLD, I might have issue. But should I have issue, anyway? For those with more experience here then I, what sounds most likely? Is this bike "clean" with a simple replacement cluster, or has something been amiss in it's seven year history?
