You are looking at RADIAL valve arrangement like MV of now and Rudge of the late 30's.

BMW has gone the distance with this design. Look at those short pin pistons! Radial valves and double overs with slappers.............all dreams have come true. No one will like chasing this BMW around the track or over the mountain..........whichever comes first.

Please explain this Radial Valve?

[Dr. Curve]

The valves line of travel is not Parallel to each other. Rather each valve is directed toward the center line of the piston travel line. Better breathing and more costly..........but well worth it. Getting more power out of the same ammount of gas is never a bad move.

Watch out there. You're wetting your self.

Besides it's been mentioned: Zwei oben liegende, kettengetriebene Nockenwellen (DOHC) und über sehr leichte Schlepphebel betätigte Ventile ermöglichen nun eine Höchstdrehzahl von 9 500 min–1. Die vier radial angeordneten Ventile sorgen jeweils für sehr kompakte Brennräume, so dass auf die zweite Zündkerze, wie sie bei den R-Modellen bislang zum Einsatz kommt, verzichtet werden kann. Das Verdichtungsverhältnis beträgt 12,5:1.

Just not in your native language.

...and not a twin-spark anymore...

...I always thought that BMW used the twin-spark configuration to get rid off the surging...
...apparently there are other ways to stop that annoying feeling...

Well, it may be an engineers wet dream, but it still only makes 133hp. That's just as much as your average 600cc 4-banger, which has to comply to the same EPA crap. And if you don't want to compare against 4-bangers, it is still 30hp down on the 1098. And let's be real, that is the bike it will be and should be compared against. BMW should have no problem creating 160 horsies in that engine.

Special engineering solutions are great but only if they are backed by results. They have wasted a lot of resources for a result that can be achieved with the current R12 motor. So as usual, it seems BMW did the engineering for the engineering again. And who gets to pay for it? We (the customer) do. This is how BMW prices itself straight out of the market.

But it still gives me a woodie.

[Deans BMW]

Both Nate, Brian and others as well routinely blow the 1098's and other higher HP bikes in the weeds with The R1200S that does not have the power and is not as light as this new bike. Its not always the max power out put but the quality of the power or to put it another way, the amount of power under the entire power curve.

Now, the upcomming 190/190 will be a horse of an entirely different color.

[throttlemeister]

Well, that's all fine and dandy and everybody knows an excellent rider on a lesser bike can out-perform an ok rider on a better bike, but in the end power DOES matter. The performance of Nate and Brian says more about them then it says about the bike. If you have two riders of the same ability, one on the HP2 and one on the 1098, the HP2 will get its ass creamed. The 1098 is purpose built for the track and has the power and chassis to back it up. The HP2 pretends to be, but does not really, while it will cost the same or similar to the 1098S. If BMW would put the HP2 into WSBK, it would finish at the end of the pack. And they know so, or else they wouldn't develop another bike for that (not that it matters much, cause 190kg and 190hp is not gonna cut it in WSBK; Toseland's Ten Kate Honda CBR-RR has something in the order of 250hp(!) and weighs less). Whereas the 1098 stands a good chance of wrapping up next years championship.

...please TM ; let us be happy for the moment...
...don't spoil our weekend ; and let us drool over this gorgeous bike...



...I also can't help that it's raining over here at the moment...

[throttlemeister]

Hey I'm drooling too. And I'd buy the HP2 over something like the 1098 any day. But a bit of realism isn't wrong.

.... now you've done it .... it's gone ...

Hey guys,

here a gear range table of the R1200S HP2 Sport in mph:



Maximum speed in the 6. gear 171 mph .

[RoLoo]

...that is almost 274 km/h...
...dang...

...with only those few HP more than a stock R12S...??

No....just a bit annoying.

[SAHD]

Is that theoritical top speed? If so it should be good for almost 160 mph.

I am in!

Thanks for all the great photos guys...to me this bike rocks. I'd trade up my BCR in a minute for this if I could afford it.

On the street, and in the twisties, this bike will hang with just about anything even given riders of equal ability. But I'd agree with the nay sayers when on the race track this BMW against 600s and open classers will be a back marker.
Sorry to say so. But then again I could be wrong, so who cares.

The dreams of many Boxer fans have become reality. The launch of the new BMW HP2 Sport sees the sportiest, most powerful and lightest Boxer of all time hit the roads.

Based on the R 1200 S Sports Boxer, that competed successfully in Endurance race events this season, the new HP2 Sport bristles with high-end, top-quality racing parts. The HP2 Sport is the third model in the BMW HP ‘High Performance’ range. The HP series has been designed by engineers at the BMW factory to produce bikes that represent the ultimate in riding performance; with the skilful harmony of exceptionally high quality components resulting in a high-end range of motorcycles.

For the new model, BMW Motorrad has developed the most powerful Boxer engine ever. This has been achieved through the complete redesign of the cylinder heads to create the first Boxer engine with double overhead camshaft. This allows the engine to reach higher revs therefore generating more power. Achieving over 128hp at 8750rpm and 115Nm of torque at 6000rpm, the engine really packs a punch. With a dry weight of just 178kg, the bike’s power to weight ratio promises impressive performance.

The HP2 Sport has been designed with racing components originally developed from lessons learnt in Endurance racing. For instance, the frame has been strengthened from the standard one fitted to the existing R 1200 S model. Also the HP2 Sport is the first production motorcycle to be available for road use with a quickshifter. This enables fast gear changes without easing off the throttle or operating the clutch, making for a smoother, faster ride. As well as this the bike has a close-ratio six-speed gearbox, for maximum acceleration. Continuing its race credentials the HP2 Sport comes complete with a light-weight carbon fibre fairing, including a self-supporting seat unit.

Further innovative sport design elements include a MotoGP-style dashboard, forged aluminium wheels, Brembo brakes with radially mounted calipers and specially developed Öhlins front and rear suspension units, making the bike truly track ready.

The endurance racing features of this bike are clear. A first for a Boxer engine, the new stainless steel two-in-one exhaust system is placed under the oil sump, guaranteeing optimum lean angles. The HP2 Sport is also comes complete with adjustable footrests, brake and gear levers to allow for the optimum riding position for both racing and the road.

Although racing potential is clearly at the forefront of the design of the HP2 Sport, this does not mean forgoing safety design features such as ABS. Available on request, this sophisticated anti-lock system has been designed specifically for the model, and has been configured to be switched off for track use.

Tony Jakeman, BMW Motorrad’s Marketing Manager said, “The HP2 Sport is a bike designed for riders with an ultimate passion for sports riding. With numerous cutting-edge sports design features and a high performance engine this model is really leading the way for BMW sport production motorcycles. The bike is indicative of the brand shift that we have taken over recent years, whilst maintaining the uncompromising standards expected of BMW Motorrad.”

The on-the-road price of the HP2 Sport is expected to be around £14,500 (to be confirmed) when the bike becomes available at BMW Motorrad dealerships in Spring 2008.

Comes with a quickshifter...cool!

these heads are awesome, i have't dug into the k1200 engine so i'm a bit in the dark about valve adjusts. looks like they just have some kind of cam follower but i see no provision for shims or any kind of adjuster,

would be nice if they had a hydraulic buckets and eliminate this maintenance chore...

Ron here the range table in km/h:

[pdonnell]

Somebody mentioned "longevity requirements" of this motor.
.
News flash.....BMW isn't spec' ing 250,000 miles out of their motors any longer. There in the game (marketplace) for power. Longevity and bullet proofness is a bygone era for BMW. Just look at how there responding to the marketplace...rolling out more power......

You can't get 160HP out of this engine, not air cooled. It would have to be liquid cooled. Which would make the cylinder heads stick out more. I would say at least 4 inches (101mm).
