Couple of interesting posts from a couple of British writers from, (I think Performance Bike), British magazine.
They have just taken on 4 new long termers and will be modding and evaluating these bikes over the next several months so it will be interesting to hear their first hand accounts. Here are the comments from the first session from each rider for the 2013 BMW S1000RR, (not HP4) and a 2013 Kawasaki ZX-10R.
BMW S1000RR
-"It's the best bike in the world, say's Matt. It really does make every other bike feel like rubbish. And I don't know why but I'm really worried about you ending up in a hedge."
This is the fastest most powerful bike in the world and I'm already a touch anxious without Matt's sage words. But as I head out on my first ride, the bikes so confidence inspiring that I feel immediately at home and any trepidation simply drops away. It ismind bogglingly fast, sharp, and violent like a Zx-10R, but cossetting, flattering and accomodating as a Fireblade.
I love Sport bikes, always have, and S1000RR's riding fashion suits me, or maybe I'm more suited to it after all these years of racing in a crouch. If someone had built a bike specifically for me, I don't think they could have done it better than BMW.
For something as extreme as this, the S1000RR is almost too easy to ride fast. The bike has the wonderful weightless sensation through corners that is, for me, the whole point of riding a motorcycle. It attacks bends with astonishing accuracy in a completely unflusterd way and gets back on the gas with such naked aggression that keeping the front on the ground isn't an option. And the sharp metallic bark as you quickshift through the box is spine tingling and so addictive you have to do it again and again and again. And theres power everywhere; whatever gear, whatever revs, whatever throttle position."
Kawasaki ZX-10R
-"No one makes a sports bike as single minded as this one. Even BMW's S1000RR makes concessions to road use with things like heated grips. A ZX-10R is just about going fast. It has the best handling of any liter sports bike, brilliant electronics and revs like an absolute demon. And it's the bike to have in Superstock Racing.
With over 175HP at the wheel it's explosively fast and while I don't agree with the commonly helf notion that it lacks mid-range, this long stretch with it will either cement my opinion or open my eyes to the uncomfortable truth. It's a bit of a cop out to say the 10R handles like a 600cc supersport bke. However, it does exhibit a lightness of touch and rate of turn not too far away to it's smaller sibling, but a more accurate statement would be that it handles like no other liter bike, especially the way it turns.
I haven't touched the suspension yet, electing to give it and the engine a chance to bed in before fiddling. First impressions are that it feels to soft at the rear and too firm at the front. Elsewhere I've been fiddling with lever and footpeg position to find a place for everything so I can find a place for everything so it's not something I even have to think about while riding. I'm going to try and get out on the track as much as possible on the ZX-10R and get at least one big road trip done. I'm going to carry over all the best mods i discovered on last years GSX R750."
