Roesner kit is one of them and it makes good power but most important it makes tourque that would rip to first 3 gears... there are these guys that also prep the bike and make power out of the boxer engine: http://www.rehcing.com ...and others...
Just because ... this forum has guys that don't do tunning to this bike that does not mean that it does not have potential ... there are bikes with only software and filters that produce :107 hp to the whell and 116 NM ... that is good power...
Anyway ...don't let these guys dissapoint you and if you wanna tune the engine and get more power just research a bit and doit...if you need more infor for the german forums ... then i'll post it and you can start asking questions over there ...

Thanks for your understanding.

I'm sorry no answered your question the way you wanted it answered. But the truth is I doubt anyone here is Stupid enough to have bought the R1200R expecting to be able to add 20 hp to a bike that's as dialed in as it is. I suspect most intelligent folks who wanted a naked BMW with 150+ hp would have bought a K1300R (or K1200R) which has the power out of the box that you seem to want? I guess my question is why didn't you buy the correct bike to do what you wanted?

Headers.

I don't know if it is a "radical" solution, but I was at my dealers today and the sales manager mentioned it is a modification I might like. I questioned how much a slightly bigger diameter exhaust system would really make a difference, and he said it eliminated the catalytic converter which makes a huge difference.

Maybe catalytic converters are not required where Dorian comes from, but I am all for playing with the bikes and making mods. The Rosner and Rose big bore kit looks like it would be a lot of fun, maybe even make the bike scary.

My experience with increasing hp is mainly with cars, and my SOP sense there is that you need to increase hp by 15% to make an increase you notice, one that yo can feel. At 109 stock hp that would amount to nearly 20 hp increase - very unlikely without compromising this bike way beyond what's reasonable. I'd take it for what it is or buy one of the K-bikes which make more than 130 hp. How much do you like the boxer configuration?

I think it's humorous that the originator of this post only posted four times almost four months ago and never came back. It would have been interesting to know what modifications he carried out and how it affected the performance of his machine.

One has to wonder if he was serious or, if to use a crude colloquialism, he was just 'pissin up a rope'.

Not everyone is an internet forum junkie like ourselves. Like many, he probably just came along to see what we have to say. He's now probably busy installing a big bore kit for some serious power gains that some here told him was futile and visiting forums where people give concise answers to honest questions.

Just as possible that he received the same answer elsewhere (e.g., don't bother beyond the exhaust, and nothing will give significant gains), and is now on a Hayabusa. Or dreaming about modifying it.

Only just read this thread and the strive for more power is common across all bike forums no matter the make or model.

The strange part of some of the replies from people saying "buy a different bike" is that it seams to be comming from people who have bought a naked roadster and then search out the biggest screen they can bolt to the front of it.

Pete (happy with the power and nakedness)

Pete
On the other hand if you read through the posts on this forum you will find lots of people that love their R1200Rs naked, but you will also find quite a few that have with little effort turned theirs into successful long distance tourers. Also you will find a few that use their R1200Rs as dual sports able to run along 90% of the roads that are supposed to be for GS bikes.

But I can't find any posts from someone that has worked their bikes up to the 120 HP level or to be competitive with the Jap liter bikes on the street or track. You would think with the mix of people world wide on this list anyone that knew of a really hot R1200R would have posted it.

Just came across this:

http://www.visordown.com/motorcycle-new ... 19582.html

I guess everyone has a different point of view. R12R is a great naked bike that can be enhanced to be a super comfortable lightweight tourer that will eat up the KLMS. For my needs the bike is rock solid and reliable with worldwide support on hand. To me this is what the RR is all about but hey that is just me.....

Your right in line with most of us Mike. But that is a neat kit.

OK, after all the nay saying, here is one alternative for bumping the HP on an R1200:

http://www.maxbmw.com/r1270/index.html

A recent issue of BMW Magazine also had an article on the Rosner and Rose hop up of an R1200R.

Go for it...

ok

If horsepower upgrades floats ones boat then go for it! From my narrow minded point its not what this bike is all about. To be honest for real-world riding this bike has enough torque and grunt to get me in some serious trouble. For me I prefer a more relaxed and consistent pace in order to cover some serious distance in a day rather than some serious speed in a day. Sorry didn't mean to gibber on but can't help myself sometimes.....

Come on Mike. It does look cool. (except for the coolers under the cylinder heads)

okay you got me... it does look cool. Whatever someone wants to do with their moolah and their ride is all good with me. Just wouldn't do it for mine.... dunno just saying. anyway i used to be vague but now I'm not so sure

Anyhow Mike, it seems that it costs you blokes (is that right) down under a fortune to import motorcycle stuff. So it would be cheaper for you to buy a V-Max, put on a loud exhaust and a 250mm rear tire and be really really cool

Enjoy your riding season, I'm waiting for the first snow storm to try out my new snow blower

The cost for us guys or conversely blokes is pretty high because we don't have the range due to the size of the market. Freight cost is where it hurts the most. A$ is strong against most currencies. The real Big issue for me is "suck it and see" method of buying. I never really know what to expect until the delivery arrives. That's why this site is so good because I can learn from you guys. Anyway I might pass on the V-Max for now. Weather here is not too hot and I hope you have cranked up the horses on your new blower,,,,,

swap your rear gearing out for a gs final drive.


http://wossneronline.com/forged_pistons ... cts_id=850


Just the Wossner Rods would remove 200 grams each of weight off the Crankshaft:
.. 1lb. of weight off the Crankshaft .. and these long cranks need Weight Removal
as they Flex after certain power levels.

After 140HP .. 1200 engines start eating Rod Bearings .. so Blueprinting the Oil System .. shim the Oil Pump
to raise pressure .. have the crank_rods_pistons_flywheel & clutch assembly Lightened & Blueprinted & Balanced
at a Pro Balancing Shop is also Mandatory .. you'll enjoy the effects of the Crankshaft Lightening_Balancing greatly.

RB Racing has some info on their Kit for the K&N Air Filter replacements.

Install Larger Intake & Exhaust Valves.

Bore the Throttle Bodies.


If then .. you still desire Uber Power .. their TURBO kit is presentable ..

You wouldn't need the 105mm bore kit .. just the Wossner Connecting Rods ..
as you want Cylinder Wall Thickness to control the Pressure and the smaller
Piston will have less ROCK to it .. meaning higher RPM's.

If you like .. go with the Wossner 105mm bore kit when you order the Con. Rods
.. these come with bored & matched cylinders ..

Then get your Computer Software remapped .


As far as the Lightening Balancing .. use a Dedicated shop .. the Automotive Racing
community knows who is best .. Google .. call around to the Top Builders ..

Pick your most used cruised everyday RPM level .. that is what you'll have the
Engine Balanced to .. 3,000 RPM with a Harmonic of 6,000 RPM perhaps.

As you reach 3,000 RPM the engine will get way smoother .. as you run above it
vibration sets in .. same with reaching 6,000 RPM level .. so .. 2,500 RPM has
a Harmonic of 10,000 RPM .. the Wossner Lite Rods will remove big amounts
of Vibration .. less weight bends the crank less too .. think it over ..

Do Not Call San Jose BMW to do it as your Pockets will be SUCKED DRY of Money..
.. they will just send it out to the Shop YOU didn't bother to find out about and
charge you a whopping FEE on top of it.

I suspect that once you've done all of the Above WITHOUT the TURBO kit ..
YOUR Engine will be Beyond HPII Boxer Cup Quality .. it'll spin up faster & make RPM quicker
.. a ' Blip ' engine .. and Power Delivery will be such that you won't get KILLED
deep into some Highway turn forgetting that TURBO Bikes are ' Light Switch ' items ..
.. instant shrieking Banshee .. smokes the Tire at 70mph .. you correct & high side .. Adios.

TURBO Bikes are for Straight Lines .. louzy Road Racer.
