220km/h in 5th

That’s interesting, my X ADV does the same. I think it’s to do with governing the throttle, I can almost redline it in fifth, and once six gear comes in it slows down( I think it’s because they are governed at 105, ( on a private road, of course) ))

What do you mean with “governed at 105”? They are limited? I think it has to do with limiting fuel consumption when cruising in 6th.

Limited or governed, same thing really, in six gear, mine is not able to rev more than Hondas preset levels, you can actually feel it pull back as you can see in that video the OP kindly posted
I’m guessing it’s the same for the transalp out I will find out soon

That would be weird. That would actually mean that reducing the sprocket size would make the top speed lower instead of higher, since the max revs stay the same.
Looking for a patch to remove that restriction. Not to gain more top speed, just because I don’t want my bike to be restricted.

It is weird, I know on the T7. If you increase the front sprocket size it lowers the revs and you’ve got that better high speed and there was no engine restriction, but I’m sure in time people will change the front sprocket to see what happens.!

On my ex adv, I can read it to 6500 rpm in 5th as does freely hit the rev limit or just about but as soon as it goes into six, I can’t get anywhere near it

If 6th is restricted in revs, then increasing the front sprocket is the way to gain more top speed given that the engine power can handle it. Which it looks it can. I find it weird that Honda would limit top gear too revs. But if you say so, I believe you. I just haven’t seen this before in over 50 years of riding bikes.

I’m thinking, are they limiting the top speed because the RPM are not limited in any other gear?

maybe for tire speed ratings?

If that was true, then top speed should be the same in 5th and in 6th. In the video you can clearly see that in 6th top speed is significantly less than in 5th.

I’ve just asked a chap I know why this could be the case and he immediately came back and said it’s to do with not exceeding the speed rating on the tires that Honda recommend to fit.

So example, it’s unlikely that fifth gear will do 135 miles an hour and a rider is less likely to use this for a sustained period.

This is our take on it, but if anybody else can shed any more light, then I will be very interested to hear for sure!

I wouldn’t go 200km/h on the Transalp anyway. That’s not my riding style and that’s not what the bike was made for. But I’m curious to see if anyone has another explanation as to why the bike goes so much faster in 5th than in 6th.
