HP4? I don't need no stinkin' HP4!

I'd say I've got more power and am around the same weight if not slightly lighter, and a better battery (LiFePO4). The HP4 also doesn't have a Brembo RCS19 master cylinder. DDC and launch control would be nice, but I wouldn't pay for it.

But it is true that if you're starting from scratch, the HP4 is a pretty good package to start from, instead of the whole list of mods I've picked up over the past couple of years.

I'm with you on this argument, but I would like to see your bike on a scale just out of curiosity.

me too - in order to weigh less than the HP4 I need to have lost 16lbs. The exhaust took off 8-10lbs, the battery about 5lbs, PAIR valve and carbon canister 1-2lbs, all the carbon fiber maybe 1-2lbs, and HIDs added 2lbs (the ballasts). I was just thinking about getting my bike on a scale this week.

although, to be honest, my ultimate goal was to get down to 420lbs, so that I'd have matched the wet weight of the Desmosedici RR. It's doable, but it'd take another $8-10K on top of where I'm at now...and so there's that point of diminishing returns.

Taking off weight sounds all good and for the most part, it is. The benefit of the DDC is questionable when compared to full race Ohlins etc however I know that BMW Australia is going to run a stock standard HP4 in the ASBK 8 hour. We'll know a lot more about how the HP4 performs after the race.

I think for me the true benefit of the HP4 is the electronics package along with the modifications to the power characteristics. To suggest a 2010 S1RR will be similar is, quite frankly...silly. The HP4 has been built for a specific purpose by BMW and I'm willing to bet they have more money, expertise and opportunity to develop a top level supersport bike than any individual on any forum.

This is not designed to flame anyone. You love you bike and you should cos it looks hot. My issue is that, regardless of the parts on you bike, it's technology is 3 years old and when talking about m/bikes of this type and especially the improvements BMW has made each year with the S1RR,I'm be willing to bet we're talking 'chalk and cheer'.

Btw, it was the changes made to the power delivery and chassis that helped the guys racing WSBK's to go from mid pack to the front. They didn't need more power or strip any weight.

On the race track--but not on regular roads. The DDC will adjust to any surface. On regular roads, which is what most will be driven on, the DDC is superior (already been tested in the German magazine PS "RR vs. HP4"). Electronic suspension is the big innovation and, I am certain, it is the way of the mc future.

When an adjustable suspension meets gps tracking to change rates for each corner, then and electronic adjustable suspension will be a great benefit for the track.

Absolutely agree!!!

I think though at this stage it's still relatively unknown for the average rider to get their head around how good it is against proven technology such as Ohlins. what gets me all excited is the thought that I can enjoy it on the track and then not have to make any adjustments to enjoy it on the road...and it won't be hard as a rock. I currently run Ohlins on my S1RR and as good as it is on the track it has to be loosened up for the road.

Just wanted to let you know my case savers, frame sliders, and bobbins added 1.61 lbs:








Thus far the carbon fiber has not weighed a bit less...weights can be seen here:

I tried to pull my HID ballasts, but I've got them secured in there pretty damn tight.

just weighed my bike with the fuel topped off - 432lbs. So I'm 7lbs lighter than the HP4 and 19lbs lighter than stock.

That's good enough for me. BST wheels would take off another 10lbs or so? Not worth the $4000. But I will do a 520 chain and sprocket and when my Metzelers wear out, I'm putting on Pilot Pures. That'll take off another 4-5lbs.

Nicely done man!

I read the whole thread, and the biggest " advantage " I can see with the HP4 is the fuel/ECU tuning by BMW Motorad in the actual ECU/control module. As they say, more than the sum of it's parts... Seems that would apply to your beautiful ride AND the HP4.

You know what stuck out most to me? The whole time I was like " Isn't this guy in Korea? " ha ha.. Welcome back stateside! I was just in Nashville for the CMA's.

I did the exact setup with ohlins. Very big difference. I also had the suspension set up for my weight and Computrak do the frame. I can't even speak on the difference. Totally plants in the twisties solid. It's solid in every aspect now. It was a little twitchy before.
