Have to be careful trusting those japanese (and all other) speedometers. But then again, all speedos have their most accurate range, and it isn't at the lower end, or when topped out. Speedos are calculated to be as accurate as possible in a range where most riding is done.
A stock 929 Honda would not get close to 180 mph. It was and is a very fast motorcycle, and once you are past 150 or so, does it really matter? Best speed runs I have in my records we took back when 929 was new, it went about 165-167(radar gun). We were trying to see if it was any faster than the 900. It was/is, but not by a bunch. Aerodynamics plays a massively larger part of top speed over just horsepower.
Not at all bashing your 929, so please don't take it that way. I used to be involved in the technical side of testing new products as they came out(top speed, horsepower, 1/4 mile, etc). A case in point is my 2006 GSXR1000 that has way more horsepower than a Honda 929. Rear wheel dyno'd at 171 hp after some fairly extensive mods. Tapped out on the 4500 ft front straight at Miller Motorsports in Utah, it ran right at 179 to 181 every lap. That was radar and GPS tracked. 180 on a bike is pretty stupid fast, but it handled it like we were doing 90 mph, not double that.But even with a 30 or more hp advantage or a 929, it only went 10 or 15 mph faster.
Crazy thing was stock geared GSXR1000K6 would do 101 mph in first gear at redline. And you have 5 more gears! So as this post started, yes, 100 is a long ways from where it was when we were younger.
The muscle cars wars of old that many of us wished we could have been a part of were nothing to what is going on now. Ford putting a Line Lock in 2015 Mustangs so you can more easily do a burn out? Really? That is so freaking cool! Chevy selling COPO Camaros that are running 8 second 1/4 miles? WTF?
All I need now is the Plymouth name to come back, a legitimate 'Cuda produced that doesn't weigh 2 tons, and I will burn a hole in my checkbook to buy one. And I don't want a rebadged Challenger. I mean a "Cuda! With a Hemi and blower with a warranty! And maybe In-Violet. Then I could die happy, lol.
