Which it isn't, at least not any more than any other heavyweight bike released in the last five years (*COUGH* CTX *COUGH*) was.

No need to choke on it. I readily will state that the CTX is definitely NOT a ST replacement. Each bike stands on it's own and is different in many ways from each other bike, ST-CTX-GW. While I do see some styling queues from the CTX in the new Wing I don't consider the new Wing a replacement for anything other than the old Wing. And it's the right direction I think for Honda to take with the Gold Wing badge.

For some reason I thought the higher the compression ratio the more need for higher octane fuel, The more compression creates pre-detonation on lower octane fuels example "pinging" and when I looked at engines that use regular fuel vs premium, in most cases the compression ratio was noticeably less.
How ever I also read that it takes regular fuel so that blows my thinking out of the water.

The 2018 Wing still linked brakes (and ABS standard). Like a cruise control previous Wings had them and I have no reason to think that Honda would drop either of those features.

Just an FYI - gl1800riders has the owners/navi manuals on downloadable links. I saw Mellow (is there another Mellow?) post over there so i thought I could reference them here. If that's a no-no then I apologize and Mellow can delete this post.

Nothing wrong with those as Honda doesn't really sell them and they usually provide free links anyway, it's the service manuals we don't allow as those are sold by Honda and many will copy / distribute those illegally.

So the shared owners manual is:

Looks like it covers all the models since it calls out when a feature or control applies only to a certain model or group of models.

It's more complicated than just compression ratios. For one thing going to a 4-valve head allows a central plug location which is ideal compared to a two valve head where the plug is stuck over to one side. That makes for a really long flame path to reach the other side of the combustion chamber. Since gas burns at the same rate regardless of RPM, more spark lead is required to allow time for this long path to burn. This additional spark advance makes the engine more susceptible to knock. I'll bet with the centrally located plug, Honda was able to back off on the ignition advance. Another factor is CC turbulence, the better the fuel/air mixture can be evenly mixed, the quicker the burn, which also allows for less spark lead. Even Harleys have finally gone to a 4-valve head, it was overdue for the GL.

Wow, had no idea, just thought any large displacement Japanese m/c since the early '80s had 4 valves per cylinder.

Higher compression ratios cause fuel/air mixtures to compress more which creates more heat. To slow this igniting reaction down a bit, a higher octane fuel may be reccomended, which is a bit later igniting than a lower octane fuel. Using a higher octane fuel can eliminate any pre-ignition issues. In other words, lower octane fuel ignites quicker than a high octane fuel.

Per the specs in the back of the official owners manual (link in post above) the recommended fuel is 86 PON or better. As stated compression isn't the only factor in determining what fuel to use. Combined with spark timing and even spark temp are also factors.
