What GS is this?

[Taevans64]

Hi guys

I’m currently looking to buy a cheapish big adventure bike to mess about on the miles of forest tracks around our home, here in Poland. I also want it to be a bit of a project bike come restromod to introduce my kids to the delights of spanners as opposed to virtual reality. One of the bikes I’ve come across is this

https://www.otomoto.pl/oferta/bmw-gs-gs-1150-adventure-100-sprawny-ID6Bsc2G.html#beaf6e5820

Pricewise it is in the right ball park and it looks in ok condition. But I am confused over it’s description. It is listed as a 2000 adventure. But Dr Google reveals adventures were only introduced in 2002. It also appears to be a twinspark which, if t’interweb is correct, only started in 2004. As it is calibrated for miles rather than km’s it is possibly an import from the UK or more likely the US, the vendor lives close to two companies who import bikes and cars from the States.

I am not overly bothered about the accuracy of the description, if I go to see and it fits the bill I’ll get it. But I would like to know what it is so I can order the correct parts for it.

Thanks in advance for your replies

The bike is a standard 2000 1150 GS but looks to have had a later model engine fitted.

I would be very wary of buying it

Look at the engine on this one and compare.

Twin spark models which this is came in 2003.
Looks like a standard model with an adventure beak.

Will the pannier boxes come with it?

Yes the engine is a twin spark but the rest of the bike looks to have started life as a year 2000 single spark

Or..., it's a single spark with later rocker covers fitted (i.e. If the originals had been damaged)

Thanks for the quick reply. At what price point does ‘it looks as dodgy as f*ck’ become ‘well I only want it to mess about on forest tracks’? Also if it has had a replacement engine is that unusual for 1150s?

There are no pictures of the panniers so I presume they are not included.

Bikes nearly 20 years old so anything could have happened to it over the years - comes down to what it looks like in the flesh and how it goes/rides like.


The only thing I can tell for certain from the photos is that it is not the adventure model, the colours/decals are the same as the 2000 1150 GS I bought brand new in 2000 and it looks to have a later twin plug engine fitted so buyer beware!

Looks to me like a 100% twin spark , I’m thinking that if it was imported from UK that somewhere long the line the date of manufacture was recorded incorrectly, why don’t you check out the vin number to confirm. Other than that I think it looks good, so if the price is right and it’s registered correctly in Poland then it could be a good option for you.

These are heavy bikes off road so unless you are reasonably experienced or the tracks are very easy I would be looking for something lighter.

Here’s my two pennies worth.

I’m not convinced it’s a twin spark. I think it’s a single spark with twin spark cyclinder head covers.

The easy way to check is to look under the cyclinders for the lower secondary plugs. My guess is they are not there.

Why do I say this.....From the picture it looks like a HT lead going to the cyclinder head, which would be correct for a single spark. On a twin spark, the lead is low tension as the coil sits on top of the spark plug.

Secondly, I can’t see the wire for the lower secondary plugs. That wire is HT and from the picture it’s not visible along it’s normal routing.

Thirdly, To convert a single spark to a twin spark, is more than just an engine swop, it would require either a twin spark wiring loom, or a hybrid loom making. You would also need the motronic unit.......why would anyone bother. It’s a lot of work, for no real gain.

This is my opinion too.
Bike is actually a 2000 or early 2001 model, as it isn't fitted with EVO brakes which were introduced in 2001.

Its prolly ok engine wise ..maybe previous owner had problems with the gearbox nad swapped it for a lower mileage or better n it need rebuilt or the input shaft for the clutch had worn and couldnt get a replacement .maybe the previous owner had a mishap with the original engine and found a low mileage one n swapped them over ..??

How can you tell?

Exactly the same process of elimination I went through... Although you could piggy-back a second set of coils, they still need wiring up and I can't see anything to suggest a second pair of plugs.

This is my opinion too.

Another good spot.

It's a single spark with twin spark heads fitted and as others have said the calipers alone point to it being a year 2000 bike.

The clock also shows 0:23 indicating it's maybe resetting itself. Total guess, but with water on the dash it has obviously been given a blast with the hose recently, probably 23 minutes before the picture was taken. Is green thing on the dash another clock?

It not particularly cheap either.

 

[Nobby]

Single spark. No bottom plug or any signs of it or a coil lead plus pic showing cover you can see a coil lead and not the plastic sleeve that covers the wires for coil that the twin sparks have.

 

[King Rat]

So that is where two of the stolen GSs ended up....there is another one, a 2003 version sporting a single spark engine!

 

[snelly]

More to the point; what GS is this;; 125hp; that's some hilltoping there boy.

 

[gabriel_gs]

That’ll be the ‘incorrectly advertised’ model
