Look, I know the grass is always greener ....I too have a much loved K1300S, but I lusted after a S1000R. I kept my K bike and have a wonderful S bike also. A very good combination. Don't dump your K bike, you will be sorry. I have 120,000 miles on the K bike and between the two S bikes about 30,000 miles. They are individuals, each has its own personality.

If you don't master shift-cam technology, just push more air into them cylinders: Leaked pictures of the Z H2. Revealed on October 23.

The new Kawasaki Z supercharged needs to have been on a serious weight loss programme before it's of any interest to me, I'm not 250kg bikes

My two cents worth....

As a new owner of an S1KR, I am still learning about all the bike has to offer. And as a former owner of Honda's since the 80's, I am still learning about BMW in general. IMO, the S1KR needs very little as it is and my short list does not include shift cams at this point. However, I am always open minded when it comes to change and I hope what ever BMW does with this bike over and above shift cam technology does not take away from its basic character. Getting a few more pounds of torque is not a problem on the existing engine. So for me it would come down to what other changes they make to compliment the bike.

beech - love the 1300! And the 120,000 miles on the K bike is impressive as well. There may be a bike with a boxer engine in my future before it is all over. You are "spot on" about different personalities. I still have a Honda in the line up and find myself enjoying it as much as I do my BMW but in a completely different way.

Shift cam? who cares....  It was "de-tuned" in the first place to have more torque than the RR. I love my '19...

Cycle World published the dyno curve for the new shiftcam RR.  Nice high end...but mid-low rpm torque curve has a big dip and not what you'd hope for with all this shift cam technology...a step backwards for the rpms you are using on the street with a naked bike.  Cycle World blamed it on noise restrictions...but makes you wonder.

There is a huge difference between the Euro and US spec 2020 RR(K67), this is the dip they are talking about. Still not good for the US, but an explanation.

This mid range dip would keep me from buying one. This area is much of the range I use most of the time. Living in the 9 to 11000 rpm range is not street great. I just read an article about trying to keep an RR in the hot upper range on the track and even that wore out the rider with all the shifting. This article is in the latest issue of Cycle World and is their superbike shoot out.

I was under the impression that Euro 4 noise restrictions  were more severe that US regs...am I mistaken about that? Why would the US bike be the one with the torque dip?
