Well my 5penneth is i have owned and rode GS GSA's Rallye 1250's had 11 on the bounce and don't get m wrong had some memorable happy fun times along with a few offs spills and everything else that go's with the rove of two wheels.As Apex says you do get brand loyal and I too was sucked up in all that BMWs is best stuff. Yes the build quality was and I say was very good but IMHO BMW are going south fast! the build standards are not what they were particular the plastics are cheap and flimsy. The weight and the TFT poor connectivity wheels, engine paints etc plus a boredom factor brought me after a bad accident last year to look at other brands. I bought the V4 Ducati MS and soon realised that it was not for me the V4 had to be revved didn't feel like adv bike and the poor Brembo M50 front brakes which should have been amazing were dull.{Yes they were bed in) I liked the hayes brakes on BMW. The other thing was the cluttered TFT well to much going on strong noises from air box huge chain clunk clunk! and I just didn't like the Duke. Its amazing and well made but it was a case of
not for me. So I then moved onto a bike id always poo pooed
KTM. I was hovering like a Kestrel over the KTM Configurator and priced mine up with luggage at a tad over £20k the 1290 s in ORANGE that is. I rode the demo 1290s and the 850 to and boy they are both nice bikes. Let me say this a GS flatters a lot of riders riding where as the new KTM makes you ride the bike! the unlinked brakes means you have a back brake that actually works and the whole feel of it is "Lets Go" Im 5,000 miles in from end of April and yes I have issues like you do with all bikes.
The GSA GS will always be the comfy slipper! very nice but The KTM im riding is agile feels lighter than it is and puts a huge smile on your face. The downside for me being a fatty is the ergonomics I have the OEM seats the High heated Ergo seats and now th flat Rally high seat. But im getting there.
When you wash a bike properly you clean a lot from how well or not its made I have to say I was well impressed with the KTM Plastics are solid and tons better than BMW IMHO and the wheels are great the engine is a proven Badd ass and gives you fun sedate or on the gas. The chain for me coming after 100's of thousands of miles on the shaft drive BMW's (Not without failure) has been a new learning curve but easy as someone says just add the tightness up a bit and it's sweet.We ride down some very bumpy back lanes and on my GS1250 Rallye I used to think cant get better than this over these bumps! this lane is 4 miles so a good test yesterday on way home we rode same lane I remembered to swap the KTM suspension " on the fly" into Street mode and comfort suspension it really was amazing! the difference was noticeable. In fact the KTM ride Modes you really can feel the difference as you should be able to then theres Rally Mode with changes the whole bike... if thats your thing.Switchgear like every bike change takes a bit of getting used to but I'm fine with it now.Fuel Unlike the Ducati i was in the low 20's the KTM will give you all the fun you need and still give you a 52-54mpg return.
9k miles service intervals and a bike that you can put on the centre stand with ease push around gravel car parks easy etc.Go's like a missile Looks good when you let it grow on you

Suffered same with Ugly Beemers

So for me its been a Happy change to KTM a bit of
love hate thing I don't like how you cant turn your headlight on and off and you cant run the DRL with the headlight on, sometime when it does its auto change cars think your flashing them.Its each to their own I would not say i will never have another BMW but right now i like team orange....I wish I had tried a few Other brands and not had the last 12.5 years riding GS GSA 1200 1250's
