I think they put 100,000 miles on it. Kia tests its engines for 300+hours at full load and above redline for short periods. I’m not talking about joe dirt chocking the front wheel and pinning the throttle on a production bike for a full day. The point is, put oil in the damn bike, do some periodic maintenance and run it.
    https://youtu.be/GNPB3RtHN2M this is the link for the Kia testing video, it’s two minutes. If it doesn’t work, search Kia engine test in YouTube. It’s the first video.
    https://youtu.be/_jCmu6qJXX4 ford link, this video is more in depth and better because I like Ford and Mike Rowe.
    Ok, good, glad someone else thinks this way too. Maybe it is an upstate NY thing.

    We get obsessed with creating the perfect engine operation profile for our bikes. I think it appeals to our engineering/perfectionist urges. What types of oils, warm up regimens, number of milliseconds at redline, and so on.

    What is the point? Are we gonna keep these bikes until they have 250,000+ miles on them? If so, great! If not, all you are doing is extending the life of an engine which will likely never get the opportunity to be tapped into because the bike be long gone by then.

    As JW says, change the oil once in awhile, follow the manufacturer's recommendations, and enjoy.

    If you exist to gain satisfaction and pride from neurotically maintaining your vehicles, enjoy that also!

    As for engine longevity tests, I believe them. Not sure if they really tell us anything, though. I remember the 1948 Tucker (also a flat motor) was run around a track at WOT for 5,000 miles at the Indianapolis Speedway in the testing process. And that was in 1948!! I think Opas was there...

    Unless you hold it against the rev limiter a long time on every shift, I doubt if it'll hurt anything. I hit mine sometimes, I never worry about it.

    I played with old Brit sports cars when I was younger. Those tachs had a yellow line and a red line. You could run up to yellow continuously, up to red for a short time.

    It will be purchased cheap because it will be worn out with high mileage and with all kinds of scratches and scuffs. Resell is unimportant.

    It’s YOUR bike. Ride it any way you like.

    These engines are tuned very mildly and have low redlines. My 1986 Concours had a 10,500 RPM redline, and many sport bikes are far higher than that.

    Knowing Honda, they left plenty of cushion when they set the RPM limits. Being a 2 valve engine with mild cam timing that favors the low end, I suspect that without a limiter, power would drop off noticeably before any damage would occur.

    I do agree with those thoughts F6Dave. It is exelerating to go through the gears with gusto with almost any bike, these F6Bs do it well. Of course if you want to poke along and smell the roses this bike does that well also. I would never suggest you should just get a scooter.

    The F6B can ware different clothing depending on one’s mood. That is what I really appreciate. When it’s time to sight see, it does very well. When it’s time to push ours and /or the bikes limits, you may just find both. Hopefully not at the same time. I’ve been asked, told, that I should have replaced my first F6B with a FJR 1300. I explained the 2 most important reason why I didn’t. #1 it’s way to tall for me #2 I will want to use it to it’s full potential. Meaning it’s speed and cornering ability. I already know how that played out on the B. I ride with people that have the FJRs, and mistakes happen to them also. AT much higher speeds.

    Here is a good article on the topic of hitting the rev limiter. From the article:
    "Longer answer: Redlining is OK, provided you're doing it in a specific sort of way. Banging off the rev limiter is bad, revving the snot out of an unloaded engine is bad, and riding around with the engine at full song for no reason is... well, not bad, but it's not great. Effectively, it's up to you to know the difference between "use" and "abuse."

    "That’s a bit different than the person who just sits there with the throttle wound out, either overspeeding the engine and not upshifting, or perhaps is just banging it repeatedly off the rev limiter. One is a quick trip into the forbidden zone, the other is staying for a meal, asking for a wine list, and starting with a salad."https://www.revzilla.com/common-trea...line-my-engine
