BMW K1200RS Power upgrade, going from 98hp to 130hp

[@rodolfosabatini1417]

In italy the original power of this bike is, exactly, 130 hp. The power of 98 hp was reserved to the K 1200 LT

[@georgegeorgas3840]

everywhere the RS has 130hp and 98hp the first LT. maybe he is doing a downgrade from 130 to 98hp!!

[@mikem597]

The best bike I've ever owned I had two different ones .Fast, fun to drive,good storage.

[@mikem597]

These were great bikes. I had two different ones. They were great to drive

[@clifford.B]

wow. It's so simple. Great video. Thankyou for sharing.

[@jeangaelcognat4988]

Merci pour le partage et le montage...beau boulot

[@ozmosis0074]

Love my k1200rs. Guess I didn't know they sold a lower hp version.

[@restorationvalve]

Yup, euro versions came with only 98hp, upgrading the air box is one of the easiest OEM upgrade

[@ozmosis0074]

​@@restorationvalvea 30% increase in power will be nice. Any reason why the euro version had the drop in power?

[@rgrauduzis]

@@ozmosis0074 It was because of insurance policies in europe. Bikes with power less than 100 hp was in lower insurance group.

[@ozmosis0074]

​@@rgrauduzisthat makes sense, motorcycles seem to be one thing the US government hasn't really regulated the fun out of yet. 3 day msf course and here's your 200hp H2

[@adventureswithshawstie2641]

What two wires does that yellow jumper jump?

[@chrisjamieson8537]

What is the compression ratio on the 98hp RS engine? The US model K1200LT 98hp engine has a lower compression ratio than the RS (10.8/1 vs 11.5/1).

[@atomicdmt8763]

mine is 130hp outta da box!

[@atomicdmt8763]

THANKS! I didnt know this was a thing!

[@AkA-zg1sj]

Great step by step guide. Thank you for sharing. I've a 1998 K1200rs from Germany. Is it 98hp? I can't wait to take it apart and check that air box.

[@rgrauduzis]

It should be. This K1200RS is also from Germany. If I'm right, every European RS is 98hp.

[@ScaramouchedaVinci]

@@rgrauduzis No wrong. Mine is from 2001 and has 130 PS in Germany.

[@rgrauduzis]

⁠As I said, If I'm right, but now I know that I'm not. Thank you, for information.

[@AkA-zg1sj]

​@@rgrauduzis Thank you.

I looked in my 2002 K12RS maintenence booklet that came with it. It showed in the specs 2 versions, one 76 kW and one 92 kW, if I remember correctly. A note for the lower power one said it was for national use of some areas. It did not show power in HP.

[@jayteezee]

It's probably a stupid question but you say the yellow relay tells the bike that larger tubes are fitted, but it looks like you are removing the relay in the video. Is the yellow relay removed to give 130bhp or do i need to buy one and add it to the bike?

[@restorationvalve]

@@jayteezee it looks like a relay, but actually it’s just a jumper that connects two wires, there’s nothing in it. With it the ECU assumes that the bike has the smaller intakes for the 98hp, without it the bike ads more fuel for the bigger intakes.

[@jayteezee]

@@restorationvalve Thank you!

[@JuhaEerikki]

Would this work on a 1999 K1200LT German model as well?

[@restorationvalve]

@@JuhaEerikki hard to say, I haven’t checked how the LT model is set up. The engine is the same, but there may be differences

[@JuhaEerikki]

@@restorationvalve I also haven't researched this yet, I just saw your nice video. Someone said that LT and RS have different compression ratios. Anyways, if this would work on the LT it would increase the fuel consumption, right? Would it increase low down torque, say in the 1500 to 3000 range?

[@georgestepney6864]

Great video well presented. Where did you get the parts and their specifications please.

[@restorationvalve]

Parts were found on eBay. Instructions can be found in the BMW service manual that you can easily find on the internet.

[@irakperez]

Great video! Thanks a bundle!. I didn't get what was the yellow relay about. What was it about?

[@restorationvalve]

The yellow relay ( just a jumper in disguise ) tells the ECU that it has the larger tubes, so it can adjust the fuel correctly and thus giving more power.

[@paulagarten378]

The radiators on my 1999 K1200RS are barely sufficient for 98HP, I wonder how they will do with 130HP

[@restorationvalve]

The owner of this BMW hasn’t had any problems with cooling on this bike. It has participated in several motorcycle rides/parades where the speeds are below 20km/h on summer day’s averaging 30°C. The cooling should be all good considering that the power on lower speeds seem to be more tamed, on road driving speed the airflow takes care of the cooling quite well.

[@paulagarten378]

maybe a good idea to change the motronic to 2.4 version to prevent over speeding the engine

[@restorationvalve]

Don’t really see how a over-revving could be caused by this. The limiters haven’t changed. This modification is how BMW adjusted the power to suite the European market.

[@rgrauduzis]

And by the way, reading from specs, k1200rs already have motronic MA 2.4

[@adventureswithshawstie2641]

What does the yellow jumper eliminate?

[@restorationvalve]

The yellow jumper tells the ECU that the larger intake tubes are installed and more fuel is given to the bike

[@rgrauduzis]

From k-bikes: “since this power limitation needs a different fuel-injection map in Motronic ECU, a Yellow relay is installed in the electrical junction box (under fuel tank) to trigger this new map. It is in fact a "dummy relay" as internally it functions only as a jumper wire to make a connection into the ECU.”

[@georgestepney6864]

Well presented video. Where do you secure larger boots and relay dummy from? A road test would really sell your modification.
