R100RS convert to a naked R100

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.

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.

a bit unflattering

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



........and badges

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

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.....

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.
