BMW R1200RT/R1250RT Forum

Today while out on my '23 RT with the ACC engaged, as I approached a traffic light and started downshifting without touching the brakes or clutch, the cruise control stayed on and the speed didn't slow down (it just revved the engine higher).

Is this working correctly??? I thought when you use the Gear Shft Assistance Pro it always deactivated the cruise control while downshifting. Any help, thanks.

I have a R 1250RT which is a 2022 model and when I disengage the cruise control I turn the throttle forward or hit brake or clutch levers. The throttle was quite stiff turning it forward in CC when the bike was new. It is freeing up now as it gets older. I have never tried shifting down with out using the clutch while in CC, but will try and see what happens, when the snow melts here.

Found an R1250RT review on Bennetts BikeSocial which says, "differentiating from standard cruise control, ACC allows gear changes without deactivating, pushing the throttle against the stop deactivates it".

When downshifting using gear shift assistance pro, should the throttle be fully closed.

Today I got out on both my 2020 RT (no ACC) and my 2023 RT (with ACC).

1 : The 2020 RT, with cruise control activated, downshifting without touching the brakes or clutch, cancels the cruise control, (I personally like this better) and you start to slow down.

2 : The 2023 RT, with the ACC activated, downshifting without touching the brakes or clutch, does NOT cancel the cruise control, and you keep going at the same speed in a lower gear w/more RPM's.

3 : The 2023 RT, with the ACC turned off, and using the regular cruise control, downshifting without touching the brakes or clutch, does NOT cancel the cruise control, and you keep going at the same speed in a lower gear w/more RPM's.

I do like the old way better, for when you come upon a twisty section of road, I would just bang down two gears and lean into the turn. Now I'll have to tap the brakes first, then downshift.

Another thing about the ACC, is that at the farthest setting you're just too close to the car in front (especially if the speed is above 45MPH), here in Arizona the speed limit can go up to 75MPH and it will give you very little time to react yourself, (my two cents). I keep the ACC turned off for this reason, to me it's just too close for comfort.

A lot of cars are going this way with the cruise! our car you can resume the cruise and work your way up the gearbox without it cancelling

Instead of tapping the brakes to switch it off twist the throttle forward will cancel it

Yes, you are correct and I'll just twist the throttle forward before downshifting.
