My '06 Accord (4-cyl VTEC engine) had a valve clearance inspection @ 100k miles per the maintenance schedule. The inspection was
"listen for abnormal clicking and adjust if necessary."
As regards the NTs long valve clearance interval in the real world, my guess is that many (most?) owners short shift them and revving to the max in the gears is rare which helps avoid unnecessary wear on the cams, rockers, and valve stems - at least that's true for me. The difference between upshifting at 4,000 vs 6,000 is HUGE as regards how many times the valves have to cycle open & close!
The last time I checked valve clearance was Sept 2021 @ 78k miles and one exhaust was looser than the others but still within tolerance. Prior to that, it was checked in July 2017 @ 61k miles and one exhaust valve was loose and needed adjustment. Thankfuly, it was on the rear cyl because I hate trying to adj the exhaust valves for the front cyl since it's so difficult to see what you're doing! The 17k miles in four years is because I have a 2nd bike (NC700XD) and it gets ridden from March-to-November and often on longer rides.
