The Yamaha has the shortest stroke in the 1000 class. Do the maths and it has to do a higher engine speed to do the same amount of work. It always has to be running at higher speed compared to the Gixxer, ZX10 and the CBR. Higher engine speeds means higher wear.

Give me a ZX10R you can drop the clutch at any rpm and hit the throttle and it goes. On the ZX10R you can open the throttle at any speed any gear and go. That is one thing I am sure the R1 can not do. Rev it like a 600 yeah it can go fast but is it better I don't think so.

Yes it can. I tried it, and it pulls as hard as the zx. Down low and up the top. With turbine like smoothness and superior stability.

I don't think it will make much difference to wear if you look after it, make sure that it is nice and warm, and has good oil in it and change it often. How long are you going to keep your bike anyway? 10 years? Not many people bought the zx to keep it for the long haul. This is not a Gold Wing we are talking about. People buying this type of bike do so because they want the latest and greatest. They are not going to own them for very long. They are going to change them for a new one, that will be by that stage revving higher, will have more horse power, and therefore will be faster. Even yours revs higher than any big bore Kawasaki ever did before it.

Let's get back on the revs topic.

I've had a ride on every 04 1K. IMO I don't like the R1. One reason is that you have to carry more revs for the bike to perform! More revs at the same speed as the 10R.
Now monti's point is noted that because the R1 is at higher rpm's it will deliver more power at the same speed. True. But, you are still at higher rpm. Which means that there will be more gear chaning required to keep the revs up! Right?
I am and will always be a fan of twins! I enjoy low end grunt when I'm on the road. I also enjoy revs when racing!

Another question! Why would the clever journo's rate the R1 as more rideable if you need to carry more rpm's? Higher rpm's also mean that you have to be more precise in your riding.

I know this post isn't going in any specific direction at the moment, I simply want your input on the rpm issue!
I personally don't like a bike that revs to 15K. And the 10R does have more low down power than the R1. Compared to the one I tested anyway!

Do you feel the same or am I barking up the wrong tree?
If the zx has the closer ratio gearbox, as you said, then who is going to change gears more? Think about it.
The R1 also has a close cut gearbox!

I know nothing about bikes!

indeed it does [smilie=1: the 04 R1 pals in comparison through the low & mid power range to the 10r & G1k.....in fact the earlier R1's 02,3 perform better through this area than the 04.

Change gearing and be done with it. We all do it anyway.

Put the R1 and 10r in 4th gear (just picking this gear because it will require some power down low to get the bike moving at a lower RPM) at about 40-50 mph and nail the throttle on both. The 10 will leave teh R1 no problem because the R1 does not have the down low power or torque that the Kawi produces. Buddies and I have done this, same outcome everytime [smilie=1:

I'm concerned about losing top-end. Theoretically, swapping front for 16T will reduce top end from something like 306 to some 286.

Both bikes have engines that rev quicker or slower. The R1 has a short stroke which makes the engine rev QUICKER, The ZX has a slower revving engine. Now listen I'm not talking about actualy RPM's but the speed at which the engine operates and spools up. This is another advanteg the ZX has on its side due to its lower revving engine, and being able to start making power lower than the R1. Also this aids in the close ratio gearbox, it requires less effort to keep the bike in the power. The R1 would require 2 downshift to get the bike back up into its operting speed as to the ZX, because the R1 needs to rev higher in passing and etc. I hope this made some sense.

Theoretically speaking if your into the top end stuff then don't bother with a 16t.
FYI after installing my 16t i managed a highly optimistic / indicated 186mph and still gaining slowly.
