My AT 2018 was behaving standard first 2100km, but afterwards something happened.
Before the curve on the road as normaly I just release the throtle bar and want engine to break the speed, but at the moment I reach 3000 rpm the breaking power of the engine is off and I'm in panic because it's surprising and dangerous as I'm speeding into the curve. Instantly I have to grab for brake lever and pedal to decrease the speed this way.
Seems as the fuel delivery was renewed again but too soon or too high above the iddle speed.
The change of this behavior in comparizon with first 2000km is significant, but "service mechanic" says it's ok and it's not
Have some of you ever got such an issue?

On my 2017, engine braking is a a function of the drive mode. The 2018 ATAS has more options, but on the standard AT, try setting the mode to Sport 2 or 3.

Or I should say that downshift frequency is a function of drive mode. If you are in sport, it will hold the gear longer when accelerating and downshift sooner when deaccelerating.

I know the ATS has an engine braking setting. Does the 2018 AT have this same setting? It sounds like engine braking has been turned off.

My bike is with manual gearbox. And I tried to set all three levels of engine braking, however, even at the strongest level it is braking weak. But the point is, that the braking efect dissapear at 3000 rpm. Technician stated it's normal and the fuel delivery is renewed at 3000 rpm just in order to keep iddle speed. I say it's bullshit, because riding at 3000 rpm on 6th gear means more than 90 km/h, it would be impossible to brake with the engine.
But first 2100 km it did not behave this way, it was just normal.

Hi feel badly for you, this is the type of thing you do not want to go wrong on a bike.. I can see you have a problem somewhere & it shall take nothing short of a specialist to fix it.. or replacing a lot of parts to see when the problem disappears.. Honda dealerships generally do not have these type of specialist in house & also they do not have spare cpu's & sensors lying around to swop your bike out with.. Diagnosing the problem properly with intimate knowledge of the bikes workings are required here. I know I have been there with a vibration on my Honda VFR1200FD. After purchasing the workshop manual doing many things & using my own engineering mind I found that on the throttle body one bypass hole was blocked.. NO ONE WOULD BE ABLE TO FIX THIS AT THE DEALERSHIP.. It's a new bike so keep giving it back to them & then finally try to get a new bike from them so they could ask Honda Japan to get someone to fix it.. The reason I say this is that it could be a safety issue!!! I ride a 1200f DCT & I can imagine going down a pass in sport mode & the braking stops working the way I am use to it.. This could easily cause serious injury or even death on a sharp corner..!! Maybe use the words UNSAFE to ride, since this is what it is.. I sincerely hope you get this sorted..

Africano, you are 1000% right. It's trully unsafe and first ride when it occured I was twice almost off my lane ...

Today I had a 45 minutes phone call with that technician but he is saying all time the same. His diagnostic gadget is showing everything ok. I told him to sit on bike and go riding on some curvy road to find out how it is in real ride. No, he does not see the reason, because diagrams from the gadget are clear. All is ok.

And the biggest joke is, that according his "findigs" seller is going to reject this obvious waranty case. The bike is just 3 months old.

It's funny you mention this. I'm finally getting used to the heavy mechanical engine breaking on my 2018 ATAS (manual).

I didn't like it much at first. The last time I rode a lot was in the late 70s and early 80s (my first two vehicles were used motorcycles; didn't buy a car until I was 23). If I let go of the throttle on my 1976 Kawasaki KZ650 or my 1978 Honda 750 Four K, they virtually coasted compared to this 2018 Honda.

It does certainly make the bike much safer. But it also makes it a bit clunky when shifting in the lower gears. On my bike - anyway - if you try to do a nice, slow, easy, casual take-off from stopped... you can't really do it while letting off on the throttle completely (unless you’re riding downhill). Because letting off the throttle completely brings the bike to a halt quickly (esp. in 1st, 2nd and 3rd -- but even at highway speeds and in 6th gear: I used to be able to take both hands off the bars for whatever reason, to stretch my arms a bit, or make a quick adjustment when it was safe, etc., but with this bike, if I take my hand off the throttle at 60 Mph, it slows down so fast you'd think I was using my breaks or downshifting--it's flat out impractical (or even dangerous, depending on what's behind you) to take your hand off the throttle at highway speeds. Doing 60 Mph or better on highway? Want to take your right hand off the throttle to check your back jeans pocket for your wallet? Forget about it! Unless there is no one behind you for miles. She has a very unforgiving throttle).

But your example of coming into a corner is where the engine breaking excels. Even in the higher gears. Let off the throttle and the bike slows quickly for you, helps you navigate some of the more gnarly stuff.

The 2018 ATAS Manual has 3 EB settings. I’d like a 4th or 5th. Or more difference between 1 and 3. 3 is the “least engine breaking effect” but it still breaks fairly hard. And it breaks hard in all gears and at all speeds and RPMs.

But what you are describing *is* dangerous. The bike is supposed to mechanically break and you are *used* to it doing that (and that nonsense the Technician is spouting is BS—as I described above, my bike breaks fairly hard even over 3k rpm and even at setting 3). This is a serious safety issue. Your bike is not doing what it is configured to do. I hope they fix it for you.

In the meantime, be safe and engine break the old-fashioned way… downshift. :grin2:

Good luck, Gary

Thanks Gary,

The same way as yours was mine first 2100km - just perfect.

Probably I will have to write comment or complain somewhere higher. Maybe Honda Europe in GB

Have you ever solve this problem? Mine AT 2019 (DCT) is interrupting engine break when on heavy downhill

I have a 2018 ATAS and am creeping close to 2000 miles on it. I dont notice the EB being any more or less than alot of other bikes i've owned. Several Hondas, Harley Davidsons, Yamaha, Kawasaki, and Suzuki. I've been riding since I was 18 (now 35) and average about 10-15k miles per year via 2 wheels.

All of my EB settings are on 2 on my 18 ATAS manual. Ive never even changed them since it feels normal. IF yours happened at 2100km (1300 miles) I am already well past that with no issues. I'm sure if something goes sideways with mine in the EB department it wont take long to notice. But it almost sounds like something is causing your motor to 'unload' because the normal friction of the motor coming down in RPM is what causes EB. Are you DCT? Could it be there is something wrong in the DCT system and the bike is essentially shifting to neutral when you roll off the throttle? (ie. Like pulling in the clutch at speed on a manual bike)?

Amazing the gremlins that appear when we go from the good ole clutch to some automatic option.
I guess this will all be out the window when electric bikes take over.
Will be shame for the broom broom.
Maybe we will learn to appreciate ziiiing ziiiing instead.

IMHO perfection is when there is nothing more that can be taken away, not when there is nothing more that can be added.

If I have to ride an electric bike, I will be towing a trailer fitted with a large diesel generator to sort the range anxiety issue. They will now doubt soon be on us, as an old sod who has always relied on combustion engines, I am happy to finish my days with a crankshaft and pistons!
