Apparently the K12 series has had some issues with premature clutch wear, according to this article in the March issue of the BMW Riders of Washington newsletter:http://www.bmwbmw.org/bts/201/bmwbmw_bts_2013-03.pdf#bmw #clutch_problems #bwwridersofwashington

I did take the G650GS Sertao for a test ride. Morton's had three in stock. A demo unit on the showroom floor. A used one outside and one in the back being prepped. I took the used one for a 7 mile loop. It's quite tall but not as tall as the F800GS. I can just barely touch my heels down. Standing still it feels much more substantial that I would have imagined but once underway it's quite nimble. Being a thumper it vibrates. Not nearly as bad as a KLR but still quite a lot. There are a few places in the rev-band that are particularly bad. I think overall the video review that John posted was pretty accurate. The footpegs do seem oddly placed and are way too small. They would need to go. However, I didn't find the bike unstable nor did I think the transmission showed any problems. The bike pulled strong all the way up to 80mph. The suspension is soft, the way an off-road capable bike should be. Because of the soft suspension the front does dive a bit on extreme braking but not anything like bikes from back in the day. The seat is terrible and would be the first thing I'd replace. ABS and heated grips. The ABS can be turned off which is key when heading down rocky slopes. These days, for me and my sore hands, not having heated grips is a real liability, so that further tilts me towards the Sertao. Of course, heated grips can be added as an afterthought on almost any bike. The stock accessory plug is mounted in a very odd place on the left side under the "tank". Looking at it, I think it's probably closer to being the "right" bike for the TAT trip than anything else I've seen or heard about. It would, however, need: 1. a new seat. 2. wider and longer foot pegs. 3. a better engine guard 4. a center stand 5. hard luggage of some kind. 6. more aggressive tires. The used one they were trying to sell for $8900 or so. New they are 9400. The one in the back with 5k miles on it that was a bit rougher they said they might let go for just under $8k. The jury is still out but I am starting to change my thinking with regard to the bike. I can see myself using it around the East Coast here more than I would have thought. Back in the day I used to really enjoy dirt biking but mostly it was exploring trails ... endless miles of trails. I'm starting to think it might be fun to have one of these ... 2012 G650GS Sertao(https://adv-traveler.com/136/photos/506/untitled/774/2012-g650gs-sertao) 2012 G650GS Sertao(https://adv-traveler.com/136/photos/506/untitled/775/2012-g650gs-sertao)
