I completely agree that every motorcycle requires a unique techinque to achieve smooth shifting. It's part of each bike's character and something that it should be expected.
I also agree that the gearbox on the 1200 GSW is problematic, but I have found a technique that works for me.
On my way to work today, I experimented various combinations of preloading vs not preloading, pull clutch to the grips vs tapping the clutch and quick shifts vs slow shifts and the one thing that made the most difference was tapping the clutch instead of pulling to the grip.
Yes, it has excessive clutch drag, to the point that it's nearly impossible to move the bike in 1st gear, engine off and clutch in. That's how bad the clutch drag is. It's worse when it's the bike is cooled down but it doesn't get much better after being hot. It's easy to see this with the bike in the center stand: just engage the gears and pull the clutch in... the rear wheel should stop moving, but it doesn't... it just keeps spinning altough the clutch is engaged.
I'm taking my bike to the dealer in July to sort out a few issues (unable to program alarme remote, stuck switchgear, unexpected engine shutdown and instal Gear Shift Assistant Pro) and I'll be mentioning the clutch drag and gearbox problems.
One thing that it's strange is that some riders report no problem at all with the gearbox and others are so bothered to the point of returning the bike. If it has a design fault, all bikes must be the same and the reported differences that most riders write about must be related to the shifting technique used. If I had shifted like I do now from the first day I got the bike, I would never complained about the gearbox. I know that some riders who returned the bike and got a new one say that the new bike is much better than the one they returned and that, I can't explain.
The main problem with having a design fault is that all bikes will be the same. If BMW admits that there is a design flaw, they would have to recall all bikes.
Maybe it's time for some manufacturer to develop a gearbox, promote it as being much better than the original one and start making money!
