I am hoping to get a bit of advice. I have a 2007 K1200GT with 44,000 miles on it. I've had all the standard interval service and take excellent care of my finely tuned machine.

I've had all the standard issues with Clutch squeal, and throttle stick that many people have had but aside from the clutch squeal the bike engine, transmission and final drive have always run beautifully. I have never found any metal in any of the fluid changes.

Just took a 2000+ mile road trip after changing the oil and about 1500 miles into the trip I got a false neutral between 5th and 4th gears while down shifting through some twisties. the next morning I downshifted from 6th to 5th gear to pass a vehicle when the RPM's spiked and the gears slipped then suddenly gabbed with thud and a clank. Then slipped again, and grabbed. The next pass it occured again. Initially only occurring above 5000 RPM with a good amount of throttle. I had to start skipping 5th gear. Now if I do go into 5th gear it slips under any load at all. All of the other gears are solid so I assume its not a clutch issue.

I am afraid I'm going to have to replace the entire Transmission, and of course I'm out of warranty. I have owned 5 bikes over the years and put close to or over 100K miles on all of them and never once had a transmission go out. Any ideas, as to what it might be. I've scheduled an appointment with my dealer service department, but they can't see it till next week.

This is going to set me back a few bones. $$$$$

Of course the Fuel Strip went out on the same trip but at least BMW will cover that. Only good thing is perhaps I can fix the clutch squeal and redo the clutch at the same time.

If I do have to replace the tranny, can the Transmission for the K1300 replace it?

Same thing just happened with me, I replaced the clutch plates with Barnett. Total off eBay was $159. the BMW clutch pack is about $800.

You were able to replace the clutch and fix the problem? Were you having slipping issues in all gears or just one?

I have a hard time believing its just the clutch since all the other gears are engaging properly. I'm concerned the dogs for 5th gear are pre-maturely worn, or were incorrectly machined causing a premature failure.

But I really hope you are right.

I agree Downunder. Its unfortunate but probably the right conclusion. Will find out for sure this week.

Skiboy, any further on your problem? My 07 S is doing the same thing. 3rd gear is unusable as any load causes it to come out of gear for a split second then engage again. I am going to pull the tranny to see if it is repairable. If not, I will put a K1300 S tranny in it and sell it. I love BMW motorcycles but wish they would build a dependable bike.

Yes KG4KDN I can provide an update. The transmission completely locked in 1st gear while trying to get it to the shop. Had to trailer it in. The transmission was torn apart and there were metal shavings everywhere. The dogs had started to round in 5th gear and slip and and slipping and grinding had thrown off metal and eventually a small piece caught and bent the shifting fork locking it in first gear. Had to completely replace the transmission and clutch. I was told that in some cases there is a small component on the shifter they can adjust on the left side of the crank case once they get it open, but after checking that first, they had to pull the entire transmission.

I would suggest not riding it till you can get it opened up. or at least change the oil and check the magnetic plug for metal. If you have any metal shavings in the oil they can get into the engine and cause damage to the master crank, and even the cylinder heads and seals since the engine clutch and transmission share one oil system. If the master crank is damaged you'll have to replace the entire engine as well.

The cost for the new transmission, clutch basket, lamellar/and clutch plates and new bearings and seals was over $12,000 from BMW new. I found a wrecked bike with a nearly new transmission and clutch online and bought both for about $1,400 with the surrounding parts, and brand new aftermarket clutch plates from Barnes $300 (BMW makes you buy the whole lamellar package for 800.00 when all you really need to replace are the plates for $300.00) The race team replaces their plates with Barnes. The whole job was done for about $3500 with labor. I found my parts at rubbersideup.com who just happened to have a very low mileage 08 that was just laid down and they were in the process of parting it out. By the way the replacement clutch plates also got rid of the annoying clutch squeal I have had since the bike left the shop. BMW has repeatedly told me I'd have to buy the whole clutch assembly and Lamellar from the K1300 to get rid of the clutch squeal. Turns out I just needed new clutch plates. The BMW ones are poorly designed and have much smaller grips than the Barnes plates.

Hope yours isn't as bad, but I would expect the worst. Your one of several I have talked to with the same experience. I'll most likely sell mine in the spring now that its running. Not going to take the risk of another total transmission failure. Its the best bike I have ever owned when its running, but I have owned a lot of bikes I have put over 100K miles on and never had an engine or transmission failure on any of them. Its happened to too many people and BMW simply won't stand behind anything.

They guy at the shop admitted that they under engineered the final drive and the transmission to handle the power of the K1200GT engine. You can have a shop back east machine the dogs to an angle so they won't slip but most likely the final drive will blow up because it can't handle the torque. They made some changes to beef up the K1300 but not enough and were having some of the same problems. Rather than completely re-engineer the line BMW had enough problems they just scrapped the whole bike and went to the K1600GT/LT. Originally they had planed to launch the K1600LT and keep the K1300GT. I think the K1600GT is nice but it just doesn't ride like the K1200 and K1300GT, too bulky and not sporty enough. The K1600GT is just the LT with the top case off and slightly different footpegs. I'm trying to figure out what sport tourer I'm going to buy next. I love my BMW but really tired of them not standing behind their bikes. If I'm paying a premium for their ultimate engineering then they should stand behind it.

Slight hi-jack

I too recently replaced my clutch at 55,000 mi (and 3 coils...). Hopefully no transmission issues, but I'm feeling like you - time to go to another brand, I just have lost confidence in BMW. I'm looking at the new KTM 1290 GT and the updated FJR. The K1600 is just too heavy. The KTM looks great on paper but I'm not sure about its real world ability with a passenger and trunk as I think it lacks space. The FJR is a know entity but a slight step back in power/weight vs the K12/13.

What are you looking at?

Just a bump after a couple years to thank the OP here. This is one of several threads on several forums which was invaluable to me in helping to diagnose my weird situation on a '06 K12S which had a fuel pump failure and 2d-gear-trans-dog-failure at almost the exact same time, and I was lost as to how the pump could fix the on/off power in all gears but 2d.

I haven't looked at this post in a while. One last update. Bike ran great for another 10,000 miles then the engine blew in Feb of 2018. Too much metal from the transmission failure made it into the engine and wore some of the oil channels reducing oil pressure. Tried to fix it by replacing oil pump, etc. but nothing worked. I could get a used engine online for $2500 but I decided I was done with it and wanted something more reliable. I don't have enough info on the condition of the used engines and the bike's value is at around $5,000 after labor and effort it just didn't seem worth it to worry about another failure. I am currently getting ready to part out an otherwise perfect 2007 K1200GT Panniers and all. Photo of the bike currently.

Parting it out

Skiboy,
Very sorry you had so many problems with you KGT and it's death. If you would post pics from multiply sides I may find some bits I could use, and others too.

Sure, everything is in pristine condition except for the Engine. A few very minor scratches. I have the original seats, plus a 2 year old Custom Russel Day Long seat, as well as the original factory windscreen barely used, and the custom aeroflow windscreen. Also have both Panniers and a matching GIVI 27 Liter Top box, if anyone is interested. It will all be going on e-bay in the next few weeks. Just been too busy to pull it apart and start posting. Attached a photos. Clutchplates/Lamoliers have only 10,000 miles. Everything sells at 25-30% of the BMW list price for new.

I think I would do the same thing. I actually found a 07 K1200r gearbox on Ebay. Found it had the same part number as the K12s and bought it for $250 taking the chance. I put it in myself because I could and dont like to pay BMW prices. A year and a half later and it is still going strong. It the engine bites the dust, I too will part my tricolor K1200s out no doubt.

So what are you going to get now??

Need a right side pannier if you get to the point indicated. Whole unit, not just the cover; though I have the lock cylinder and all the rest of the internals from my own....The old one got melted. Don't ask....

My 08 K1200S had the same problem, but I did not keep running it once I saw brass in the oil filter. Should have had a warranty and did not now have an 08 K1200GT with a motor and drive train warranty. I plan to change the oil a lot more often and check for brass in the oil. I know it does not make much since but I will rebuild if it happens again. There is not another bike that it even close to my current ride.

I bought a 2017 K1600GT. The engine doesn’t have the same raw power and acceleration in the upper range. But it has a lot of torque in the lower range. It handles lighter than the k1200 due to a lower center of gravity even though it ways nearly 100lbs more. I still miss the exhilaration of the k1200 it was so fun to ride. Smooth and fast. I couldn’t find anything that compared anywhere I looked it with anything I rode. They all had issues. I considered buying a used k1300gt but ultimately decided to go with the 1600gt because I got a great deal. It’s been better than I expected. I was worried about the weight. But it handles nicely. Power is smooth, just not he same kick in the pants acceleration between 6000-9000rpm you get with the k1200

Yes I have the full panniers for both sides in near perfect condition I will sell for $300 each. A few very minor scratches from lazy boots while mounting the bike. I’ll take some photos and send them. Private message me your info and I will text or email directly. I’m pulling parts off and shipping now.

Actually the top case I have for the bike is the Shad SH50. It’s a used 50 Liter Top Case. Case and mounting brackets available for $200 looks great on the silver 2007 -2008 bike and matches perfectly.

RDL seat

Skiboy,
The Russel Day Long seat arrived today and it is in pristine condition and looks very good on my bike too. It was a pleasure working with you and I would encourage anyone who is thinking about buying any of your parts to rest assured that you will have a hassle free transaction.
Thanks again,
Lonnie
BTW I sent another guy to you about the shield from Adventure Riders.
