    Does anyone have a picture what the bike looks like with r100rs fairing removed?

    No pic, but I'd imagine it looking something like a plain ol' R100. :wink:

    Except with no front indicators, and clock and volt meter wires blowing in the wind.

    I think an RS bike doesn't have Headlight Ears because the headlight is in the fairing. Of do you have the headlight shell? And just need the glass?

    You need what ever isn't there to make a headlight and you need front turn signals and stalks to hang them on.

    Check out where the ignition key is on the RS. A naked bike has a different switch I think.

    A nice clean RS fairing with the brackets and other extras is sometime s a desirable thing to have. It might sell.

    An RS is the same setup as an RT. That means that if you remove the fairing, you will need headlight ears. The stock headlight will mount up to them. You will also need turn signal mounts and the signals. You will also need to find a place for the ignition switch. It can be retro fitted to the left side of the headlight, just like any other naked R100.

    And you will need to either remove or tape up the wires for the volt meter and clock.

    Minor rant below:
    It has been done numerous times. I know it is your bike and you can do whatever you want to it, but, I prefer to see an RS or RT left as is. If you want a naked bike, go buy a naked bike.

    It had been sitting around (already naked) for a while before it came to me so its getting a bit of a clean up at the moment, but I'm going for shabby chic. The ignition switch is flapping in the breeze at the moment but can be fitted into headlight. I will fit knee pads

    Not sure what you mean by headlight ears, as the RS already has them. Are you talking about the signal stalks?

    I've ridden my RS without the fairing a few times, headlight works fine. The headlight is not part of the fairing, it just slips into the lens boot.

    (Just have to figure out the signals and forget about the clock/voltmeter.

    The RS headlight is attached to a mount that is on the steering tube of the frame. It always points in the direction of the frame and bike. When someone mentions 'ears' they mean the mounting pieces that let the headlight be mounted to the steering forks.

    When I got my 'wrecked' R100RS, I removed the faring and then cut the already bent faring mounts ... so that the headlight was still held by the steering tube mount. It worked fine ...

    But if you want it to 'look right' ... you'll need a set of 'ears'. They can be had fairly inexpensively from Ebay. There are also aftermarket generic one's that look OK too.

    PS - The RS faring also holds the 'ignition key'. This key will need to be moved to the headlight bucket ... and that's where the genuine BMW headlight ears will be handly (because the BMW method (at least for the RS vintage) put the key in the hole created by the bolt connecting the headlight ear to the bucket!).

    I did the same thing years ago ... The bike is long gone ... but it was a great learning experience.

    On the first (Bike version 2.0) you can see where the key is meant to be on the naked bike. On the side of the headlight bucket.

    Yes but the headlight mount is part of the fairing mounting structure which is why it stays straight when you turn.

    What will the bike look like? Well it will look like whatever you put on it.

    I met a rider who pulled his fairing removed a bunch of stuff like the headlight and replaced them with /6 parts. Now his bike looks like a /6 a big RS logo on the engine, and it was all just sooooo wrong:lol3

    No it's not, it's part/connected to the frame's steering tube. The fairing is made to come clean off with only disconnecting the upper harness quick connect. 4 bolts and the mirrors and it's off in 5 minutes.

    I'm not saying it looks good, but I rode mine for 2 months without a fairing, and it was fine, the light still stays in line as it would anyway with fairing.

    When someone uses the term headlight ears, they usually mean the 2 triangular pressed flaps that have bolts on each side of the headlight (right?)

    I think you misunderstood me. The headlight mount is part of the fairing mounting support structure which is connected to the steer tube, which is why it stays straight when you turn.

    It's not part of the actual fairing it's part of the metal structure that the faring bolts to. At least that's the way it is on my 77 r100rs

    The headlight stays straight and is little further forward then normal, the brackets or ears that hold it also have two pieces of tubing attached to them, which serve as the mounting structure for the fairing.

    You can unbolt the fairing and remove it and the light stays put, but it's not a normal headlight mount.

    Here's Bs bike from his post.

    Though the headlight is further forward it stays with the bike.

    That's exactly what I said.....:dunno

    Except, I never said it was a normal headlight mount, just that it would work, which was the question spawned by the OP's inquiry.

    Wow. That's about exactly how I set up my '92 R100RT. Minus the blinkers. I don't have any in front. I first did that to my R65LS in '89 I think it was. I liked the LS setup even more because I canted my speedo above/center the headlight via small tubing welded to the mount and then made a cool little cover for the back of the speedo out of sheet metal and a trick tube for the R65's speedo's canted cable mount. I had never seen even a photo of anyone else doing that at that time. A lot of people use to check it out at rallies and whatnot. The R100 instruments are too much trouble to deal with so I mounted them almost just like above on my R100.

    On both bikes I welded some tubing just inside the fairing mount tubes and use them for a windshield mount. Aluminum rod bent just so to clear the bars and whatnot. A stop washer wielded on the rods to stop them in the tubes welded to the headlight mount with threaded ends so the windshield mount easily bolts on and off the headlight mount. The windshield is frame mounted. Effects handling none on either bike. Windshield on or off in minutes, the bike handles better either way for the headlight, windshield, and speedo, in case of my R65LS being frame mounted. That setup also makes the front end so much easier to work on and ESPECIALLY set up which is SUPER critical IMO. IMO, those stock headlight ears confound aligning the forks big time. The only draw back IMO is less turning radius but no less than RT's and RS's have to start with. Just less that a nakid bike with a fork mounted headlight.

    Yeah I know. I wasn't disagreeing with you at all. I was just adding something to what you said. That the fairing mounting structure, (which is kind of ugly imo) stays with the bike like the headlight.

    I still don't understand why those that want a naked bike, don't just buy a naked bike. Many have tried to explain it to me, but it just does not make any sense to me to bastardize a perfectly good RT or RS.

    As they say, it is your bike, and you can do what ever you want to it. Just don't go calling it an RS anymore. Cuz it ain't one. What you are creating is often called a Frankenbike, by the purists.

    I love the looks of the above setup.

    Why did I strip my RT. The RT deal fell in my lap. I gave it a fair trial. Not my cup of tee but I personally don't care for RS fairings either. Too heavy. My fairing was sold and created a RT somewhere so I don't feel too guilty. Offends the purist. I could give F all about the purist. I love modified bikes when they are modified to work better than the original. Unfortunately, a LOT of cafe, bobbers, and scramblers offend me. Ruining good parts to not work. Get a Harley!

    I hear you there.

    It's one thing if it's been severally damaged, or possibly even a neglected RT :D, but I can't understand why anyone would want to pull a good fairing off a R100RS as they are such a nice ride with the fairing.

    Last Friday I ran into someone who'd pulled his fairing off his RS while riding up in the canyons. He initially said it was too hot behind the fairing, and then added that it looked cooler without the fairing and with the toaster tank that he'd put on it.

    When I asked him why he didn't just buy a vintage toaster, he said they weren't as fast, and didn't handle as well as the RS.

    True enough I guess.

    Technically I'd say a true Frankenbike is something that's significantly modified with parts from other bikes to the point it's steering, suspension, or handling has been dramatically altered.

    For instance I have a 79 R65 Frankenbike that has DRZ400 forks, and a R1200GS monoshock in the rear. I built that bike because it was not only fun, but the original bike was destroyed to the point it would of cost more to restore it then it was worth.

    Since the bike was already destroyed I don't feel bad about making the changes. It's now a very fun ride, a one of a kind, and it cost me about a third less then trying to restore it back to it's original specs.

    So a couple of months ago I strike up a conversion at work with an older gent . Start talking about bike ... and WOW ... finally someone that doesn't own a Harley ... Actually he has 4 Beemer's and is looking at letting one go as he is about finished with his total restore of a R90S .

    The bike he was looking to off load is a 81 R100S ... Just what I am looking for in my next project of a mild café .

    When I get there to see his other bikes ... and he has done a wonderful job ... I notice the S actually has RS stickers . He then tells me that he has the total fairing that is included in the sale .

    Sigh ... I just know that if I do end up getting it I will convert it back to an RS ... and do I really need two RS's ???

    I am definitely in the " If you want a Naked bike buy a Naked bike and leave the fairing bikes to us whom appreciate them " ( unless its unfixable ) School.

    This is almost exactly what happened to me. It fell in my lap. And I was able to sell the RS faring (even though it was damaged) for what I paid for the bike ... I don't feel bad about it at all.

    I look at it from the bikes perspective. Do you think the bike would prefer the faring, and someone to pass it over? Or would the bike prefer someone to care for it, make it run, and actually use it?

    Warped, no? :lol3

    I know my R75/6 loves me for rescuing it from it's last owner, getting it back on the road and for paying all those past due DMV fees.

    My R65 feels like a total Badass with it's "New" DRZ forks.

    Anthropomorphizing? Hardly They talk to me, they really do. :lol3
