I thought I would just make a separate thread to highlight my experience. My bike was built in factory with the GSAP and from the first moment I had gotten it I felt it wasn't quite the same as the demo RS I had ridden, but I wrote it off as my memory being cloudy. I distinctly remember finding the RS working better with the GSAP than the XR when I demo'd the two bikes. Never really had an issue with it not working, but it just wasn't as smooth as I remembered and I figured maybe it was because I was permanently balls to the wall on the test ride (which the GSAP does like after all) and the more docile day to day riding showed up it's true colours. Not like it ever failed on me but it was just inconsistent with an "elastic" action at lower throttle openings. WOT was always fun and games and never a problem, but especially the 1st to 2nd shift would be very very odd at times no matter how hard on the gas you were. Fast forward a year and I went to Sri Lanka for a month and upon my return the quickshifter was doing behaving very oddly. Sometimes going down into 1st it simply wouldn't blip the throttle and instead smash down into gear and other times going up into 2nd it would shift but then either not quite go into gear or pop out back to neutral when the torque arrived. Reported it to BMW and my initial logic was that because the bike had stood so long maybe the drop in voltage had seen it lose it's settings. Many guys on here reported a "software reset" making a different to their own. Mechanic requested to have the bike for three days stating it's a somewhat known problem with water ingress which would explain why the four weeks would mess it up as it has time for the corrosion/rust to settle. Rocked up yesterday to fetch the bike and upon asking what was wrong or how they fixed it I was simply told the unit was replaced with a new one. Kudos to BMW compared to every other bike or car I owned before where getting something sorted under warranty always required a stern word with the boss they pretty much volunteered this one. Now he didn't say there was a revision to the units but did claim the new ones are nicer/better so I was meaning to take a look and see if there were any part number changes with the 2017 bikes maybe. Either way there is a major difference to the operation of the unit. Where previously I wouldn't even attempt it below 4000rpm it now shifts happily from 2500rpm when just cruising down the road. 1st to 2nd is still a bit different from the rest, but that is understandable as the action is much longer from the underlying gearbox design. It still requires a firm foot to shift, but then I can say that for the gearbox in general so it's to be expected really. Reason for the thread? Well to bring it to the attention of others that if you are disappointed with your GSAP unit and feel that other people saying it's awesome are delusional or just easy to please (much as I did) take it to your dealer and have a moan about it because chances are it is in fact actually buggered and not operating the way it should be.
