I've got a bunch of issues with this bike, and basically all of BMW's offerings under the R9T name.
They all use the old air cooled motor. I don't get why, when they've got the improved water cooled unit running quite successfully. Oh, they'd have to add s radiator. Like big deal, even dirt bikes have them. I can't help but think it was for the same reason that BMW made the 35is cars, they had an excess of the motors sitting around, and the rest of the design work isn't very expensive.
To piggyback off using the old motors, BMW compromises on features that have become almost standard across the board for BMW Motorrad, but can't be offered here. Now I may not be 100% accurate here, but I know for sure a lot of options aren't available. Traction control, cruise control, heated grips, and the quick shifters. While these are luxuries that one doesn't need, that's what BMW is all about in their Motorrad division. I've got their S1000RR, a full on race bike. It's a hell of a machine, able to run laps with the fastest bikes made. Yet I can settle back fairly comfortably, get 48mpg, activate the electronic cruise control, and flip on the heater grips while I pass the miles. I've got 21,000 miles on it and love it.
The R9T has the heritage and old school look and feel, but it falls short on the BMW lineup. That's why I don't own one.
It's a retro bike, lots of other manuf are doing the same thing. People who own these things love them, many BECAUSE it has none (or fewer) of the electronic gizmos. Keeps the price down too, go out an shop a new liquid cooled GS adventure, it's pushing $30k loaded.
Personally I prefer owning the actual older bike vs a retro, have had an '02 R1150GSA for 10 years and currently four other bikes. But I can see the appeal to other riders of this retro niche. If you don't like it don't buy it.
Oh and not to nitpick but I think this is the more recent R1200GS "old" oil cooled motor (oil head) and not a true "airhead". It has fuel injection, ABS, and so forth, plus modern USD forks but no telelever front suspension. At $16k or so it is no bargain but compared to a full up WC GS it maybe is a decent alternative. A little like the HP2 enduro but not as rare.
I'm curious to ride a big modern BMW without the telelever suspension.
