Do not know if the alternator is designed for the life of the engine, otherwise could be pricey to service/replace.
    I've heard the same. Also that the cylinders are a single unit with the crankcase and there is no going oversize on the pistons if that time ever comes. Just what I heard.

    The engine and transmission are a single unit with a vertically split case - there is no "between". As mentioned and illustrated above, the alternator is mounted on the crankshaft (above the transmission) and appears to be accessible without splitting the cases or removing the engine. I think oversize pistons stopped being an option a couple decades ago with the introduction of Nikasil cylinder plating.

    Yeah, my Guzzi has nikasil cylinders and still has the compression of a nearly new engine. Still, what is kind of a non-rebuildable essential part of the engine would be a concern to me and would affect my purchase decision, though I'm not in the market anyway. But then I'm pretty old school and that's the direction technology is taking us.

    fify.

    when's the last time you heard of an oilhead wearing out it's cylinders? or even wearing out the original cross-hatching, for that matter?

    2013 h2o

    received my GS yesterday Has cruise control and all the rest except blue tooth, led head light and TPM Got the side cases and top box and crash bars put 50 mi in the dirt today it is amasing how well the bike tracks in the sand dirt rocks and up hill. I put it in Enduro mode and it really works. Tires are the new Metzlers which wont be out to the stores till april they are great and stick on the dry pavement like glue. I'm 70 yrs had many very good bike but this one has me the most excited and wanting to head out every day. It is comfortable and is very quick. Electronic throttle is the best-you have very, very good control. Over 200mi and tomorrow 150 plus mon 325 then to the shop for service. Can't wait to get up in the morning!

    A member of the Pelican S forum test rode the new GS and loved it. He did have one concern, on a cool day he felt a fair amount of heat on the riders area from the radiators.

    This is the one thing I'm most interested to hear about with regards to the new waterhead. Where is it going to direct the heat from the motor. Especially on the RT version that won't be as accomodating with cool air.

    There is a picture in the new issue of BMW Motorcycle magazine which appears to clearly show the alternator inside the case and not accessible without separating the transmission from the engine. I checked with my local BMW dealer. The tech who said he has just gotten training on the new boxer stated that the engine must be removed to replace the alternator. At least 4 to 5 hours for the labor alone. Kind of like replacing a clutch. Except that clutches, at least the old style dry plate units are basically bullet proof in normal use, while alternators though mostly reliable are more prone to failure.
    I'm not trying to chill anyone's enthusiasm for the new model. I'm very certain that it's a fine bike. I just don't understand their logic here....but they didn't ask me anyway.

    Probably obvious, but the radiators do have electric fans behind them. Not just exclusively police bikes any more.

    As regards, the alternator, clearly there's no belt adjustment. I'd even doubt there are brushes to replace, but don't know that for sure.

    Bosch can build nearly indestructable alternators if given the funding. My son still runs my old 1988 Mercedes 300TE that's still on its original alternator. It's not the same as chebbies and fords. I recall once replacing the failed Delco starter on my Opel with a Bosch from a junkyard. That many more subsequent miles with no problems.

    I'd agree expectations of BMW aren't as high as they maybe used to be, but surely the alternator will make it past the warranty period. (!)

    Frankly, I think there's unfounded expectations that anything automotive can be bulletproof. I nevertheless always hasten to add that a German vehicle is usually closer to being a Ferrari than it is a Camry. Some TLC required, but oh the fun! But if you want to talk yourself out of one, you certainly can.

    Fan, not fans. There is a fan on the right side, none on the left. I believe it is thermostat controlled. Also, coolant flows from left to right so the fan is on the cool half of the split radiator.
