ok, first thing... i might be mislabeling this topic. if so, please correct me.
i recently took a spin on a hypermotard, one of the ones of the hyper truck. the throttle response was incredible. it was right there, instantaneous. had to be carefull not to loft the front wheel by mistake (that was against the ride rules) . this was the second hyper i have demo'd, but i dont remember such a contrast with the last one
i think the bike i rode had the 2-1 termi + ecu. dont know about the sprockets.
my question is -- why doesnt my s2r1000 have the same kind of response? is it the 1100 cc motor? is it the exhaust + ecu? is my throttle just sticky?
i would especially like to hear from those who own an s2r1000, and have ridden a hypermotard

What happens with your bike? Does it behave different depending on how you manage the throttle?
For example i got to take a spin on one of the new Aprillia 550 supermotos. It was brand new and hadn't had the fueling sufficiently tweaked. If you gradually rolled on the throttle, it was all fine. But if you gave it a quick turn, it had a real flat spot and the bike would bog a bit before getting going again.
So how's your bike behave?
The s4rs with the ecu and termi has much more instant response than the stock bike, so perhaps that's it.
There's no 'mush' and the fueling is very 'crisp' (not easy to describe or define).
Stock there's just that split second where the motor catches up to the throttle....not hesitation...just not instant.
On mine when you turn the throttle to say 4 out of 10...the motor's response is instantly 4 out of 10. right now.
stock when you crack to 4 the motor (very very quickly) goes 1 2 3 4. again...not hesitation or stumble...but it's like the motor is like someone who can't do the alphabet without singing it...very quick...but not as nice as jumping right to Q.
ok..now I'm sounding like an idiot so I'll stop.
I think it's better fueling with the pipes and ecu.
I think you should buy the ecu and exhaust and find out. ;D

thats not very helpful.............unless someone wants to gift me the set...
as far as how my bike behaves.......its fine.
steady acceleration in every gear, no hesitation, nothing.
but thats the problem too...its only steady. i dont have to worry about lofting the front tire (unless i want to)
after riding that HM, i am really interested in what makes the difference in throttle response. i think it is a lot like the way statler described it.
so,... anyone got an s2r1000 with termi+ecu? or just the termi+ecu that the want to give away?

You're always good & helpful DP, you know that?
Good suggestions, I've not checked either. I'll add that to my list, thanks! [thumbsup]

Im with you brother. What year S2R1k do you have? Im wondering if a PCIII (if i can get it to work) will yeild the same crispness. Or we can jsut go Carbs!!!!!!!! WOOOO
You need a lighter flywheel. You will be amazed at the difference.

You need to get a S2R1k with this problem and install a light flywheel and tell us how much worst the problem gets.

ok, so does the HM have a lighter fly wheel?
If I remember correctly (can't be bothered to double check) the Hyper has full torque about 1,500 revs lower than the S2R.
Would that, at least partially, explain the difference?

this would explain a lot of it...........
but that begs the question of why?
Just checked to see if I was right. HM has about 10% more torque and it appears at 4,750 revs against the S2R 1000 at 6000 revs.
As to the "why" - it all comes down to the characteristics of the engine, ignition and injection - some are built to serve on lower revs, others on higher revs. How they do that is still a mystery to me, but I know other guys here understand it all.
If you by "why" wonder why Ducati chose this set up for the HM, my guess is because HM riders will gladly trade high revs HP for more grunt on lower revs. They simply like the experience you had.
ah, this might help a little....we share the same 992ds engine.
I went from stock M1000s and installed the termi + ecu+ airbox and felt that it rev'd a lot quicker - the torque between 3000 and 6k was/is amazing - my fuel economy took a beating and part of it I believe is because I was changing down gears whilst in the 6500 area whilst before I could keep the engine reving nice and low and keep her at 3200 then once she got to 5 go down, well the thing would just fly right past 5 so quickly after the installation that I had to relearn my shifting behaviour
It didn't alter the 'instant' feel of the throttle as you describe though, it felt like it just freed up the engine so it would accurate more effortlessly.
Stopintime and the stats could therefore be onto something!
ok,........looks like stop in time gets the prize, with statler and spider coming in a close second with their description of the termi+ecu+airbox mods.
never got to take the HM up into the higher gear range, so no idea how the revs are affected there........
wait a minute? was it the HM or another bike that had two maps in the ECU? one for spirited rides, and the other for economy.
that would be cool!
Thank you, very please [beer]
I took the HM up to 120 mph and it seems like the engine is unresponsive - kind of like the S2R is on lower revs. Not much, but noticeable.
That feeling matches well with the theory that there is no such thing as optimal performance on both high AND low revs.
Also, that speed made me praise the riding position and wind screen on the Monster.

This exactly describes the difference between my S2R1k and a MTS1000(with Termi and ecu) that I test rode. The MTS just felt derestricted and freed up. Where as my 1k feels corked up.
That's it I'm ordering the complete Termi setup. [thumbsup]
Herm, take my key at the next DIMBY. Monsterlover hated my bike but mostly because he didn't fit on it (you likely won't either), but it will give a sense of "responsive" throttle for reference.
;D

I have a pretty well set up Monster 1000 and it's way better than a stock Hyper, both in power/torque and in throttle response. I thought the Hyper was a bit dull in comparison - I've ridden three now and still prefer my 1000DS motor.
Your S2R is likely to be hampered by stock fuelling settings designed to get it through noise and emissions testing. My 1000 has DP cans, open airbox & filter and a Power Commander and has had some dyno time and the throttle response is pretty much instant. No real reason why an S2R should be the same except the lambda sensor can be a pain - have a look on the UK Monster club site as a couple of guys have been working on this

Hope this helps

the main reason is it 1078 cc and it a motard so all the powers down low simple
