Just thought i'd start a new thread.
Seems most if not all posts on here are for the older (pre 05 LT's). Does that mean that the 05 thru 09 didn't have as many issues as the earlier ones. Personally, I bought an 06 with 68k miles on her, and couldn't be happier. It seems the previous owner took very good care of it. I've had absolutely 0 problems with it, and have put on more than 15k in 6 months of riding. Would like to hear other members experiences with the post 05's. From what i see, they are a completely different bike compared to the earlier ones. I know there are still many many LT riders out there with the newer models, let's hear your experiences.
At least that's my perception.
I bought my LT new in June 2007. It is the most comfortable, most sophisticated and best performing bike I have owned. It is also the most expensive, most maintenance intensive and most troublesome.
My big failures have been final drive pinion seal, final drive pivot bearings, leaking transmission seals that took out the clutch, and failed u-hose on the fuel pump that technically left me stranded. I say technically, because it happened in my driveway just 1/4 mile from my garage. God was looking out for me as this happened the morning after we returned from a 5,000 mile ride to Newfoundland!
However, I have done extensive, expensive modifications to prevent failure: Jiffy Tite QDs, FIBIB trunk latch kit, etc. After I found the service bulletin on the squealing rear brake, the dealer replaced the rotor with the new style, but it is back to squealing occasionally. I also was plagued for years with an off-idle sag/hesitation that was very annoying and dangerous in heavy traffic. I am not sure the cause, but something I did during the clutch repair seems to have fixed it. Maybe it was the oxygen sensor, maybe it was the thorough TB cleaning, but my best guess is it was a vacuum leak in the canister vacuum line given its periodic nature (I suspect correlated to pulse valve actuation). I eliminated the pulse valve and simply interconnected the vacuum ports as is standard on the non-US bikes (thanks for that idea Sailor).
My biggest complaint of all is the dealer network. They are sparse and my nearest one, Country Rode Motowerks in Rochester, NY, poked me in the eye on a service request after I had spent $25K with them on LT, clothing and initial service visits. So, I now do all my own work including the recent clutch repair. If I buy another BMW, and that is not a high probability, I will try Kissell in State College, PA. They aren't much farther away and I have heard good things about them.
If the later model LTs are more reliable than the early models, then early models must have been atrocious! I suspect the reason is simply that the older models are, well, older and the age and mileage simply means they require more attention.
My only real apples-to-apples comparison point is my 1987 Kawasaki Voyager XII. It was far less expensive than my LT, less troublesome (never had a failure that could have stranded me), far less maintenance and with a closer and much better dealer. However, it lacked the features and performance of the LT.
