R100GS - Replacing Fairing with a Single Headlight

Hello !

There was thread on here with a similar name, but it didn't really address the notion of replacing the fairing and roo bar with a single headlight and different dash/instrument cluster. Anybody have any experience to share....


(a) What was involved?
(2) How much weight was actually shed?
(iii) Any suggestions on a different dash?
(D) How do you deal with no longer having a charge light in the charging system?
(V) DId new blinkers need new relays and flashers?
(6) Did it require other electrical stuff to be hidden elsewhere?
(g) Did you ditch the stock mechanical speedo set up and install a plug at the tranny accordingly?
(8) Any reason not to do it? (Would you recomend it?)


Hmmmm that's about it for right now. Just been daydreaming about this at work for the last week or so and thinking about maybe doing it....

Thank you much! JB

The pre-1993 (?) R100GS's and R80G/S's ran the configuration you are after....

1995 R100gs

I rigged this R65LS fairing with single headlight to it.

Changed out again into a 89 Tombstone fairing with the small
headlight. Now the bike has been sold and I'm working on another
one.

Gear Box Breather

A zero $ breather replacement can be made from and old or disused speedo cable.

Pull the speedo cable out of the sheath
Cut sheath to required hight to tuck in to where the frame splits the backbone tubes into the rear frame loops.
Install "cable" as per normal but use a solid insead of hollow bolt.


Gearbox will breath but not mist even in extreme circumstances and will not suck water at the first creek crossing.

I replaced the G/S headlight instument nacelle with a polisport trail bike crap headlight thing and saved 1.8kgs. So I guess the G/S unit weights about 5 lbs compared to whatever tons your current set up runs.

The complete nacell including idiot lights is $425.00 AUD I'd expect <$300.00 USD. plus mounting hardware @ around $50.00.
The headlight lense can be sourced from auto supply shop for $8.00 and adapted.$180.00 for the BMW unit.
Edit And a headlight retaining ring & rubber seal @ $95.00AUD unless you can adapt something automotive. end edit
Speedo & tacho are interchangable (?) but only one can be used at a time.

The polisport setup cost me $75.00 installed including new speedo.I built a bracket for the idiot light circut board & ignition switch and mounted it to the handlebar clamps.
The polisport came with indicators that required the bulbs to be replaced with a higher wattage to get the flash frequency right.
The whole unit mounts by rubber straps to the upper fork tubes.
I used an illuminated Sigma bicycle speedometer good to 199.5 kph

It took a bit of fiddling with electrical connections to make it interchangable quickly (30min)

The intention was to have a sacrifical cheap headlight assembly but just like jeans you never fall off when wearing your old ratty pair.

Tour tech makes a headlight to replace the gs fairing or the headlight on the earlier models. It's very light. It's made to accept the IMO speedo/tach unit. Though you could use a vapor or others.

Baja Designs sells a decent DOT dirtbike style headlight and winkers
This will cut down a lot on weight.

If I was going this route I'd go full meal deal
And get rid of as much stuff as possible, while making what's left behind as light as possible.

LED blinkers
GPS for speedo
Smaller tach.
High front fender (get a Japanese MX bike aftermarket part less then half the cost of teh BMW or Acerbies stuff.)

I wonder if GPS for speedo is legal? I mean, if pulled over for something else will the cop write you up for no speedo?

Hmmm good question, round here even a bicycle speedo works

IIRC the law says something about and unresettable odometer and that's about and a device to indicate speed.

Here is mine

I have an R80G/S

I put the headlight from an R80/7 and the instrument cluster from a /6

cluster:


headlight...not a great shot of it..



I don't care about the weight, I want the candlepower!

(a) What was involved?
Some planning, some buying, some wrenching, maybe some swearing...

(2) How much weight was actually shed?

I don't know the specifics, but I would guess more then 10lbs and less then 30lbs judging from the weight of my bike's stuff when I had it off.

(iii) Any suggestions on a different dash?
Homemade ABS, it's easy to work and cheap to get.

(D) How do you deal with no longer having a charge light in the charging system?
Charging system will not work with out the light or some sort of resistance.
It's pretty easy to make up some simple idiot lights.

(V) DId new blinkers need new relays and flashers?
If you use led you will need something to keep them from fast flashing.

(6) Did it require other electrical stuff to be hidden elsewhere?
Not if you take off most of the electrical stuff that's up there
but you will need to deal with some loose wiring

(8) Any reason not to do it? (Would you recomend it?)

You lose posepoints, wind protection and stock connections.
Which are often better thought out then aftermarket solutions.
Purist might come knocking on your door with pitchforks and drive shafts...

Thank you team.

Mendodave I dig that simple old school look you've got going on - it is what I kinda have in mind.

Ruksta I love your zero $ breather idea!

Good Point SB - maybe not too hard to do with some stock parts out of the ol'bmw catalogue. It would still kinda be stock then.
