Interesting factoid regarding the s1000rr/xr. BMW modeled this after the suzuki K5 1000 engine from the 2005 gsx series that won the WSB. Suzuki recently revived this engine (with updates) for the new gsx-s1000 and gsx 750 models. It is a revered design, and is particularly feral on the new bikes. Dunno - have a thing for the new gsx-s - a good way to die...

My guess, in typical BMW fashion, is they took the i-4 refinement, and removed the k5 ferocity.

It's interesting you mention the GSXR. In the latest reviews of the 2017 model, people complained about vibrations in the engine due to removal of the counterbalance shafts. This is what BMW did with the i4 in the S1000RR, R, and XR in order to increase power and reduce rotating mass. However the new GSXR also has variable valve timing. I might expect to see that in the future on the S1000 models.

I Ride: '13 Hyperstrada, '06 DR650, 2017 KTM 690 Duke
Great review and comparisons! I wonder how you get along comfort wise after a couple hours in the saddle? Every review I've read rails on the bad vibes on the XR. Vibes usually don't bother me ... and apparently you're doing OK too. So why are SO MANY EDITORS so upset by this?

You mentioned stiffness on the XR suspension. On many of the roads I ride, they are incredibly beat up, pot holes, ridges, rises and Whoop De Doo's.

On stiff sport bike suspensions I've nearly been tossed right off the bike from too stuff suspension combined with poor rebound damping.

Owned ... and loved ... many In-Line Fours. Mostly Ninjas. (2 ZX-6's, ZX-9 and ZX-10) All needed suspension help, all were FAST, most handled pretty well considering weight on the older bikes. One of the best ever? GSXR-750 and R1.

One main reason I gave up the big sport bikes was just how fast they go. When you starting riding at 150 mph on the street ... well, just a matter of time.
I remember testing (City Bike editor) a ZX-12. Riding our local back roads I got a bit frisky. This bike could get up to 100 mph instantly ... and on this twisty back road ... I got nearly caught out as I came too hot into a corner at 100 and sign said ... SLOW TO 15mph! But got it slowed down OK, made the turn. Staying clam and good braking technique saved me ... and of course ... constantly looking where I wanted to go. It WORKS!

But man, with that much power, if not judicious ... it can catch you out ... and I knew this road!

One thing that attracted me to the Hyper was how controllable it feels, now easy it is to turn in, even if your in too hot. Turns in and STICKS. That weight over the front you mention matters to me. Tire pressures really important and good suspension set up matters too. My Hyper suspension has been fiddled front and rear. Very plush, works fantastic on back roads, never wallows on 100 mph sweepers. Best I've ever ridden. Too bad my bike blew up ... still in shop.

The issue isn't that the XR vibrates so much more than other bikes, in fact it vibrates less than many other bikes. It has to do with the frequency. It's a secondary imbalance in the inline-4, meaning it vibrates at a speed twice the RPM. That means at 4500RPM (where the handlebars tend to vibrate), the frequency is around 150Hz. It feels like the vibrate mode on your phone, and humans find it obnoxious, and of course its a very subjective thing. I will say, after 1k miles the bike is considerably smoother. To an untrained person you'd have to know about and look for the vibes.

For the suspension. the XR is the first bike I've ridden that feels right from the factory. You wouldn't want to ride some super torn up bumpy road with massive pot holes - it only has 6 inches of travel. But for most things it's fine and in soft mode it floats pretty well.

Totally agree about too much speed. The bike is too fast. After my first real ride on it, I started to realize this. The bike is so composed and competent, you need to go way way too fast to feel like you're even being challenged. Is it weird to say it's too good? I guess that's why they say it's more fun to ride a slow bike fast!

Not to harp on it, but I test rode an 800st and it was the largest bike I'd ridden at that point, and i was both bored to the point of irritation, and going too fast. I couldn't see the point, It's a BMW thing,but some people like this.

Met some guys at a campsite on GSs and one guy was bragging how he was going 80 through a town and the cops stopped him - he didn't know he was going 80 cuz bike. I had 3 thoughts - what's the point, downshift, and show some respect for people in towns. I was drinking their beer so I kept quiet - but the Buell guy knew what i was thinking.

This is why I got the strada as my big bike: It's fully capable of high speeds, but it feels alive at moderate speeds. That to me is a good bike: It's fun to ride the fast bike slow, and the fast bike fast.

Well... despite what I've said, and your experiences with BMW, the XR is certainly not a bore. It's a very insane experience and far from mundane. It's just hard to surpass the experience the Hyper gives you is all
