1100S with 1150 Kit

[03 Boxer]

So what is this 1150 kit I keep hearing about that you can put on your 1100S? Is it a simple modification, is it costly, is it worth the effort? I love my 03 BCR but not very happy with the power so I'm looking for ways to get more out of her without braking the bank. As of right now she's totally stock. Took her to a track day once and had a great time but left me feeling a little under powered.

Email "Crunch". He has the SJBMW 1150 kit on his bike. It runs and sounds real good.

His name is Andy BTW.

the 1150 kit was something put together by San Jose BMW when they were looking for more HP out of their R11S race bikes

unfortunately you will have to spend thousands for modest gains with the BCR. you will need full exhaust, the 1150 kit, some type of FI module or chip, air intake and filter, ported heads and a weight savings program to still be 10 HP less and 40 pounds more than a box stock R12S. I have been down that same road and can tell you from personal experience that if its power you seek get the R12S.

with that said, and understanding the state of the economy, if you want to take a methodical approach and use the BCR as your starting point, start with a full exhaust, and the intake horn (just the horn) to free up the breathing and a chip or FI module to get more fuel in with your air. the R11S bikes are pretty notoriously lean. this will get you about 90% of what you can squeeze out of the R11S engine, and will be a perceptible improvement.

As opposed to the thousands we've spent on our R12S' to make even more power! The formula always seems to be the same: $$$ = More Power

I have done the conversion five years ago, and now have 27,000 mile since the conversion!
It transforms the bike! you can do the work yourself, pick up a set of new or used cylinders and pistons, Jugs have to be machined to fit the engine case! would cost around $1,500 depending on which way you go! would I do it again, hell yes!

Can you show photos and discuss how you removed the crosover tube? I am (much too slowly) assembling a large tube exhaust and would like to see your set up and thoughts on the changes.

Here are the mods I did. I'm very happy with the results especially since I do 80% of my riding 2 up. If I could afford it I would have a R1200S for solo and mod it like shreddr.

If it may cost something that goes with a 1100 S.

That is a LOT of Pferde.

Ya know...it sounds like if I won't a stronger bike...I need a different bike. Seems like alot of money just to get a few more ponies out of her.

119 HP at the crank vs 98 HP

Thats an interesting one,I've had my S over 10 years spent far too much money on it,i need this, i need that,and more HP te boot,i go and buy a K1200,if there's 300 miles between A nd B,i'm not sure my 1100s would be any slower,riding them back to back on a regular basis,the K motor may be more of a thrill,but the K bike is no were near as much fun to ride as my S.

1150 kit,hmmm,next time the Dollar is poor!!

[03 Boxer]

I will have to say, I have more fun riding my BCR than any other bike I've owned. I guess it's a give and take situation!

[shreddr]

once you pump up the volume on the BCR engine, you will want some worthy suspension, which is gonna set you back another few grand. if you like to do it methodically and incrementally then the BCR is a good starting point, but you will have a step function increase in performance with a box stock R12S with the Ohlins option.

i believe this means the dyno chart is from an R11S that had the 1150 cylinders, along with the crankshaft from the R1200C, which makes it a stroked, overbored R11S. not a trivial mod, and I am sure there is more that wasn't mentioned.

For what it's worth, my ZX6R is waaaay faster than my BCR but no where near as enjoyable to ride in the real world as the beemer. I start to think about how to power up the BCR and then I remember why I bought it in the first place. It is a highly entertaining STREET bike and way more comfy for a realistically sized human being than that teeny jap bike. I'm gonna throw a y-pipe a chip and a SJBMW intake kit at it and ride the crap out of it, it goes plenty fast to send you to jail as it is. If you want a really fast beemer think S1000RR or K1300S. Just my .02

Stock R1200S has about 3 Hp more then my R1150S
