I have a 2020 RS and when using the quickshifter to shift from 1 to 2 there is a noticeable jerk. The rest of the shifts are smooth. It happens all the time even when I try different throttle positions. |

Loads of talk on this subject and the differing quality of shifting. The consensus would seem to be just use it in upper 3 gears and only when you are maxing out on throttle. |

Zitat von bmw23 im Beitrag #1It's the same on mine and usually from 2-3 also. I use the clutch to shift 1-2, 2-3 most all the time. The quickshifter is best with a big handful of throttle but is manageable at lower throttle with practice. Frank

Zitat von bmw23 im Beitrag #1 Agree - the RR shifting is a lot smoother. We need that platform for a sport tourer. That said, over time, my clutchless shifts from first to second on the RS seem to have smoothed out. Plenty of debate whether that is due to machine and/or rider break-in. Stubborn - I paid for quick-shift technology in lower gears, and kept at it until it worked for me. Have fun. Sounds like you have some great steeds in the stable.

Zitat von bmw23 im Beitrag #1 Loads of threads on this, the QS works well except from 1-2 and 2-1. |

As Ray said, you can, with some time, get better with the 1-2 upshift. It works relatively smooth for me if I short shift. |

Zitat von Boxerboy im Beitrag #5 For my RS the shift down from 2 to 1 is good as well. Just have to be going slowly enough. To the OP - as others have said, big boxers have agricultural gearboxes so when you slap a QS on that you get a quicker shifting agricultural gearbox. But that said, mine is not too bad between 1 and 2 when accelerating harder. When accelerating slower and using the QS, the jerk is greater so just use the clutch ... or ignore the jerk and think of it as "character". The faster the acceleration the smoother the operation. The QS on my S bike is much smoother throughout.

I have a 2016 R1200 RS and a 2019 S1000 XR. The quickshifter is smoother on the XR than on the RS. 1-2 is perfectly smooth on the XR and clunky on the RS. And everything else is progressively even smoother going to higher gears on both bikes. That's the way it is. '16 R1200 RS |

Zitat von runnerhiker im Beitrag #8 My guess is that is the result of the inertia of the boxer engine's heavier components trying to quickly match the speed differential in the ratio gap between the lower gears.

Zitat von Ralfyrich im Beitrag #11 The downshifted is probably the best part of the system

Zitat von Richard230 im Beitrag #9 I agree. I don't think shift assist will ever work as well on a boxer as it does on a inline four.

I agree that the issue relates to the moment of inertia of the Boxer engine. I have owned both a K1600GT and an S1000XR, both of which have very smooth quick-shifters, and both of which have engines that can ramp up and down much faster than the boxer. Fast ramp up and down is essential if the engine is to match the RPM required for the new gear in the very short time available when using a quick-shifter. |
