HP2 Sport Maintenance

Hi, I used to own a HP2.. one of the first ones here in Spain. That bike had an unfortunate end but, I still have hopes of getting another one. Ive had a GS1200ADV and a Monster 1000s since but my thirst for a HP2 is yet to be quenched.

I promised that I would take some photos of the maintenance manual regarding the big 50,000km service and I have finally done so.

Here goes:




Regards,
NuTTs

I remember your crash. Can you translate the captions.

it does show some suttle differences between the 12S and the HP2S. I immediately note thelonger rod on the HP2S.

Hi, translated..

R1200s has cast pistons, left & right pistons are different..

HP2S has forged pistons and are identical for both left & right cylinders, at 50,000km the service stipulates changing the conrod bearings and piston.
Also at 50,000km the head gasket must be changed. Retorquing the nuts is not req'd 1,000km after the service.

The HP2S piston is 3mm shorter, and the conrods are 3.1mm longer. The cylinder walls are 4.2mm thicker.

There was a lot of hype about if this 50,000km service existed etc. and I remember having seen the workshop manual back then. I just forgot to take pictures and post them up.

Regards,
NuTTs

It seems that they must have really rung every last little bit out of the twin to engineer in such a drastic 30,000 mile service!

i think the sportiest, most powerful and lightest boxer ever manufactured, the hp2 sport features numerous exclusive details, previously restricted to racing, that were never before seen in series production vehicles.

The 30k mile top end work will prolly not be necessary on a street driven HP2S unless you keep it in 1st gear the entire time. Even if it loses 10-15hp in that time, on the street you'll prolly not notice it.

sujulcorn, welcome. Where are you located and do you own a HP2S?

YAYA, you are just trying to get a fleet of HP2S Jap bike hunter/killers with light weight con rods, pistons,bigger bores, and fuel management out there. I'm onto you.

No, not at all, absolutely wrong. BMW was only cautious. They wanted to avoid motors from blowing-up. Especially motors from such high-class and high-price models.

homologated stock R1200S: 122 hp DIN
homologated stock HP2S: 133 hp DIN

real life stock R1200S: 113-125 hp DIN
(difference mostly by different software versions and 3-4 hp normal spread)

real life stock HP2S: 131-138 hp DIN
(normal spread within the production)

actual tuning achievements among my personal friends and racing comrades:

R1200S: >152 hp DIN

HP2S: about the same.

New targets:
R1200S: 155 hp DIN
HP2S: 160 hp DIN

all without supercharging or turbos.

The new Woessner BigBoreKits are key measures for tuning, giving the R1200S a displacement of 1216ccm (103,0mm bore instead of 101,0mm) and together with the 128.1mm conrods a lot less weight on the crank.

The HP2S Woessner BigBore Kit lead to a displacement of 1240ccm (104,5mm bore instead of 101,0mm). Reason for the bigger bore in HP2S motors is the enlarged tie anchor clearance and the thicker cylinder wall.

Of course, the BigBore Kits are not the only measures, there's a lot more to reach that over 150 hp barrier or even break it.
But 135-140 hp DIN in a R1200S is quite easy and nothing special anymore. And up to 140 hp DIN the motors last mostly like the stock ones.

Reaching over 140 hp DIN out of a R1200S you have to work on a lot of issues to prevent the motors from blowing up.
But that's no "sorcery" and if tuning amateurs can do it, the BMW factory could do this also easily (and certainly even better if they just wanted to).

So, with 122 or 133 hp DIN nothing is "squeezed out".

Hmmm. From the old HP2Sport forum. I remember the first reported HP2S crash in Spain. I believe it was struck dead by a cage.

So maybe when the time comes for the 30k 'major service' I'd go for a Wossner piston upgrade too.

Cause 133hp is plenty for me. Very few places I can really 'safely' use all that power. And with ACH in my back yard, I found the 98hp from my old 11S was more than adequate.

tony distefano used to drive his factory mechanics nuts with that attitude. they always wanted to make his bike faster (usually on top end), but he stubbornly insisted on not wanting more power until he could hold the throttle on all the way around the racetrack.
that never happened, but he did win some chanpionships along the way...

maybe you need a downgrade

if enough is enough, and more is better, then most is best!

Is the HP2s faster than my new r75? My butt dyno tells me my airhead pulls 112.4-113.3 hp.
I'm going to just say that I think that's about right.
