CCT= cam chain tensioner
APE is a brand of manual CCT that some choose to use instead of the factory automatic CCT.
I'm not sure its been down on both sides. I think some of what is in the pictures may just be shadows. And I don't see a bunch of damage on the bar ends, etc. But if it does have some scuffs that's just a tool to use to negotiate the price.
The speed limiter is only a problem if you want to go faster than 114 mph. If you want to do that, flash the ECU. Our 2015 Tracer has never, ever had a wobble, so I'd say that its not a big deal from my perspective. If you do experience wobble, make sure your tires are in good condition, your tire pressure is correct, and your stem bearings are properly torqued. Also make sure the suspension is properly setup for your weight. If you do those things I doubt you'll ever have a wobble problem.
