Hmmmmm . . .
I'm wondering about the testing quality control here.
The "R" version is up by 2.5 hp and +/- 1 ft lb of torque, weighs less than the "S", and is apparently geared to run slightly higher revs at the same speed, and yet the 0-60mph time is supposedly almost .5 sec slower than the heavier, lower powered, lower geared "S".
The fairing makes literally no difference at the 0-60 level. While it would become a factor at higher speeds, somehow the "R" is almost a second quicker at the 60 - 100 mph dash.
That math doesn't add up in my calculator.
I'll give ya the top end, because the fairing does make the "S" much more slippery at speed, but sorry folks, I'll line up a stock "R" against an "S" in the 0-60 dash and take yer money every time.

PS Have I ever mentioned trying to get a jet aircraft to take off on a conveyor belt. Yes you did, but we are not going there again please or you'll be :banned:

Not so fast buster. On the one hand, as you say, the R ought to be marginally quicker in it's 0-60 times. The S fairing adds another 11 lbs to the weight it carries and aerodynamics don't really come into play until higher speeds are involved. On the other hand, 11 lb adds up to a typical Rexers breakfast and I'm already several stone lighter than most of you. I'll wait for you at the finish line shall I? (Insert cat amongst the pigeons icon here) Both bikes in standard trim ARE geared the same and mechanically are no different either.

I suppose the weight of the S fairing helps to keep the front on the ground in the lower gears too. . . Sadly,i dont think this point will ever be settled,cuz 2 identical riders in identical conditions that launch the bikes in an identical way with identical weather conditions is all but impossible to achieve.. & with the bike's performance up to 60/80 & even 100mph so similar it will come down to launches,reaction times,gear changes,wheelie/wheelspin control,rider skill etc rather than which bike is the quickest. For example,someone who does drag racing every weekend for his hobby is always gonna beat someone like ME on an identical bike. . . Im afaid the R v S acelleration debate will only be settled by conditions & rider skill & not by the bikes themselves...

: greed: Hence my comment about the typical Rexers breakfast weighing about the same as the S fairing.
A full tank of juice, if I've got my figures right, tips the scales at nearly 31 lbs so even that could have some kind of difference to performance figures and certainly the handling.

A full tank of juice, if I've got my figures right, tips the scales at nearly 31 lbs so even that could have some kind of difference to performance figures and certainly the handling. A couple of years ago in MCN, talented rider SEAN EMMETT , agreed a challenge with a reasonably good track jockey. The track jockey was on a then, standard Honda CBR Fireblade , Emmett was on a bog standard HONDA CB500 They raced on a track, (I forget which one). A fireblade boasting 954cc and 170MPH against a lowly CB500 with 498cc and 125mph. Emmett won by a second or so against the odds. The data logging showed how he braked later, accelerated quicker in a straight line etc. It was true and accurate. I don't know what significance this story has in relation to the topic posted because it's Easter and I have been on the falling down juice all afternoon...... But I hope it helps....... Actually, what I'm trying to say is that n'ths of seconds don't really make a lot of difference. I am a pretty average rider.....put me on a Mille, a Fireblade, a 999 and I bet most of you talented riders could beat me 0-60 and round a track at any time on a REX 'R' or 'S' in standard trim. That's my ego shot to pieces......

This is completely off topic too but that brings to mind an opportunity that presented itself a couple of years back. Rex was off the road, :violin: after the alarm/ immobiliser locked me out. Still, I have another bike, a GPZ 500s (stop sniggering at the back) so decided to go on that ZRXOC rideout at the weekend anyway. On the 500. As the owner of both bikes it's still dificult to compare the relative performance of one to the other. Rex looks a lot faster on paper. I don't ride on paper though, tarmac being the preferred medium. Obviously I kept getting left behind on the straight bits, the little z just cant possibly compete. However, its performance on the twistys surprised everybody and I don't think it was entirely down to rider skill. The 500 being lighter, a lot lighter, can brake a lot later into the corners. Surprisingly later as was ilustrated perfectly by watching one Rex thunder past me on a long straight before a sweeping bend and than almost immediately brake. As Rex started braking, I cheekily accellerated past, braking far later and probably getting on the gas sooner. I caught and passed other Rexes in the group in exactly the same way and would have overtaken the lead rider if I'd know where we were going. From that point on, along that twisty bit of road I stayed in that Rexes mirrors, shadowing its every move with ease. Maybe that's a little bit like comparing chalk and cheese. You'd have expected Rex to be a clear winner over such a humble bike. Case proven, particularly in the real world on real roads.

I know what you mean tho Grem... Theres a ride of about 140 miles that ive been doin for years & years & ive ridden it on all sorts of bikes over the years,GPZ1000RX,ZX10,Firestorm,Blade,GSXR1100,ZZR1100,ZRX1100,EXUP's,Blackbird...even a GT750 Kwak & a TZR250 - & surprisingly(or not...)my time taken to complete this loop has only varied by a few minutes each way,regardless of the bike ive been riding. Interesting. I suppose its pointless having a 170mph bike if your average speed is only gonna be 70. . .

I have to agree with wardourdrive . . . I went off Ride mag when Liisa Steele left because: 1.Liisa did a helmet review and said this particular helmet was ok but noisy. "What does she know she's a girl" I thought and bought said helmet anyway. Didn't get on with it because it was . . . . NOISY 2.Liisa did a long term test on a ZZR 600 which I also owned at the time and her description was 110% correct. 3. She is HOT TOTTY Sorry if I've gone off the subject a bit

guys you are def. missin the point about bike mags. they are abosolutely the dogs, great for coverin the kids schoolbooks, great for lookin at the piccies while on a plane, (makes you look hard)(well in a marshmallowy sort o way). glossy ones are great for usin as a funnel when toppin up oil etc. the list can go on. use your immagination.

I was primarily commenting on the lamentable inaccuracy of the stats that the "vaunted" magazine states and how, if they were anything like correct, the math doesn't add up. Now on that 0-60 run? I'm a little lighter than the average REX rider - Hmmmmmmm . . . . . and I could skip breakfast . . . . . . Guess we'll never know cuz were 7000 miles apart

How can one magazine manage to road test the same bike twice and get different results on each occasion. (The 1200S and R models are essensially the same bike.) My comment about 0-60 times and big breakfasts was a little off-topic, I agree but I doubt if any two of us here would post the same times in a shootout situation simply due to different skills and abilities, never mid our differing physical characteristcs. Once you have a bike as powerful as the Rex, in real life, real road situations, the facts and figures become academic.
