I'm not in the habit of going hard up against the limiter, however in my experience on Hondas it feels more like a loss of torque not the engine cutting out like i felt today. Any thoughts? ???
From what I understand Brett, Honda's have 'soft limiter' for the want of a better word, I think it works by not only cutting fuel but by altering timing so it feels like its gone off song, I assume that its a four cylinder Honda we are talking about?
But Dukes, two cyclinders, will probably feel like big loss of power, I've never hit the limiter on a duke.
Mmick
My S4R has a pretty harsh limiter. It'll put the front wheel down hard if your up on the back and don't grab another gear pretty quick.
The limiter on the 1098 felt much worse too, possibly because the rate of acceleration was so much more.
I used to get caught because the 1098 reved out so much more, I would get on the monster and it would take some time to remember exactly where the limiter is.
The power on my S4R drops off after about 8700 rpm or so, so it (theoretically) gives me plenty of time to grab another gear before the 10,000 rpm limiter comes on.
My ZX12R (not a Honda I know, but the closest thing I have owned), had the rev limiter at 12,000rpm and accelerated hard like the 1098. The rev limiter was a lot nicer than the 1098 and even the S4R. I didn't put much thought into, only put it down to the ninja being a 4cyl bike and hence the engine being smoother all round.
It's pretty harsh on the S2R, feeels like something major going wrong, first time I felt it I was sure I'd broken something.
[clap] Thank for the quick response guys, it felt like a harsh loss of power & all i could see was $$$.
Well, now that you have found it and know what it is, you're wiser for it.
I decided when I bought the 1098 that I wanted to know all aspects of the bike. It was a very expensive work of art, in my mind, but I didn't just want it sitting around looking pretty. I wanted to be able to tell my kids some stories about 'the good old days'. I wanted to know what it was like, both standing still and bouncing off the rev-limiter at 190km/hr on the back wheel. Not just, 'yeah I had a 1098. How did it go? Dunno, never rode it in the rain, never went over 6000rpm, never rode on gravel roads' etc etc.
Now I've sold it and I didn't baby it so someone else can have all the fun. I just looked after it so I could be proud of it being really ridden and still looking good.
Anyway, maybe that's just me.

I am with you, however that said bouncing on the limiter of a 1098 is in a different ball park to what i was up to [thumbsup]

I'm pretty sure you and I don't own Duke's new enough to _have_ rev limiters.
(actually, your ST probably does. I don't think any of the carbed 2 valve motors ever had rev limiters)

Std ECU limiter is harsh as new Ducati race ECU haven't found it yet. Does the Ducati race ECU still have a rev limiter?

No FHE ... but I thought the limiter was bumped up about a 1000rpm.
generally the limiters are harsh if the back on rpm is noticably lower than the off rpm. if you set them really close together it's hard to even know you're on the limiter as it just stops accelerating, so you need some difference so the rider will recognise it. but most ducatis are so violent it's just silly. generally i'll set them 50 to 100 rpm apart, but ducati mapping might have 200 to 300 rpm between them. so it shuts off, slows noticably then goes whammo again.
whether or not a limiter is rasied in the dp mapping varies ime. there's no consistancy in it, and really if it's limited to 10,000 as std there's no reason for another ecu to be able to effect the mechanical strength of the bits that break, ie, rods. shit still goes bang at the same rpm regardless of ecu.
ok so may sound like a silly question, which Monsters have limiters and which dont.
One would assume carb would not and fuel injected would? I dont think I have ever reached the limiter on my S2R 1000.
I DID reach the limiter on my mates CBR600 - 14000rpm is crazy!
Also would the limiters on the Ducatis primarily be harsher due to engine configuration? Given it being a twin as opposed to inline 4 - firing order and so on and so forth? I'm definitely no Jeremy Burgess.... [laugh]
the carb bikes don't have limiters, the injected bikes do. some ignition control systems have limiter capacity - the ignitech does.
just hold it open until it stops revving. you'll know when you hit it.

haha you mean there is more? I normally shift around the 7-7.5k rpm mark (when applicable) - when does the limiter kick in on an S2R 1000? I am curious to know. [thumbsup]
the dyno runs i have for s2r1000 with std ecu show 9,000. i didn't think it'd be that high.
i feel the power seems to ease about 9k on the 800. haven't bothered pushing it much more as i don't really like the thought of the stresses that a harsh limiter has on the engine/drivetrain.
After all, with the torque and power curves I've seen, theres no need to be up there for speeds sake its better to shift.

I agree as the tacho has no redline, I like to shift by feel....... [laugh]

9k standard - holy vibrating seminal fluid batman! I don't think I could put my 2 valve through that punishment :o

love your work! [thumbsup] and just for the record I have never been seen in public with my undies on the outside.... [laugh]
