Please correct me if I am wrong, but the 1125R has a cammed throttle pulley (or actuation). The end result of that is that the bike feels miserably sluggish when taking off... Not to mention you get a non-linear throttle response, almost like a I-4 emulator, you get nothing... nothing... nothing... and then it finally starts to go... The sense of urgency at take off is gone, the Firebolt used to be force to reckoned with while taking off from a stop, even when taking off at a leisurely pace the Firebolt would out-accelerate anything that is planning to rear end me when the light turns green. I have am yet to dig around in mine, but from the pictures that I have seen its not just a simple cammed pulley but rather the linkages between the central pulley and the butterfly actuators are the cause of this... Will there be a "kit" available to give a linear throttle response, or am I going to have to figure it out on my own. I am sure that with time I will get used to it, but its just not as much fun... And because the 1125R has a very similar power band to the firebolt I would imagine that it would accelerate much better. Not to mention that downshifting will become more logical, and maintaining a good distance would also become easier in traffic as it wont have a tendency to "take off" once I reach the end of the cammed actuation... Perhaps I have gone completely mad, and that may very well be... bwahahahaha! | ||

Seeing as this is the only complaint I have read regarding this I imagine you just need to get used to it.  | ||

I haven't noticed any problem with the throttle action. Seems linear to me. | ||

I did not notice this and went from a ulysses to the 1125R, but I am looking for a more sensitive throttle or less turn, I talked to Motion pro for a throttle and there are measurements to be taken to tell if I can get less turn to full go, also had a pingel throttle on my bagger and that was nice.

just sounds like a bike with a modern high revving engine. Our XB lawnmower engines have long stroke and heavy flywheel effect which help with low rev launches, bit not max RPM/horsepower. | ||
| Interex2050 |
Yeah, you guys are right... I just need to get used to it. Although just like Baggermike I wouldn't mind having a more sensitive throttle. | ||

I didn't notice that while riding at the track, but that's not a good place to practice starting from a stop. I'd say you'll have to get used to it. With 3k more usable RPMs up top, you're bound to lose a bit down below. | ||

You either have a problem or are just bogging her when you take off. It is a different animal than an XB or tuber, you cant just take off at idle with little or no throttle action like you can with our beloved old lumps. A bit of throttle and clutch slippage(just compared to the lump, not most other bikes) is required to get moving with my 1125, but once moving and over 2500 rpm, the throttle feel should be very linear and progressive, and it shouldn't feel sluggish at all. Not fun? Holy smokes Batman, this thing makes my hotrodded M2 feel like some sort of pig! I just rode my old bike today, and it felt completely gutless. (except for the first 5 mph) And my M2 makes an XB12 stock or with racepipe and ecm feel sluggish comparatively. Ask Metalstorm, we've traded bikes on several occasions. | ||

The other thing I've noticed is that hydraulic clutches take up differently than cable clutches. The lack of "friction point" feel always throws me on a hydraulic and I never carry enough revs. | ||
| Baggermike |
Try riding three bikes, different clutches, kickstands I am all confused. Mike | ||

Good points on the RPM wind-up and hydraulic clutch. The other thing I think that makes this bike feel different than the XB on launch is the fact it has a much taller first gear. You can shorten the throttle, but you will still have to slip it a bit on launch cause the 1st gear is so tall. | ||
| Wahoo |
I hear ya baggermike, I ride three different bikes also. In addition to my 1125 I have a shovel with a belt drive primary and dry clutch, also ride my wife's '03 sportster 1200. I am used to the 1125 now, took a few times to not stall the 1125. I sure love the hydraulic clutch now that I am used to it! | ||
| Fresnobuell |
Yep, i rode my XB for the first time since the 1125r purchase and boy did it seem like a SLOW machine. And once the 1125r is broken in it should be out of this world. | ||
| Metalstorm |
I'll concede, Bigblock's M2 straight out hauls butt and has a more immediate response than my XB. The 1125 though, is a freaking rocket ship. At first it seemed a little sluggish on take off but it only took the one time to learn to get the revs up before letting the clutch out. She doesn't like being below 3K and is happiest at or above 4K. I also learned to watch out when nearing 8K because that seems to be the point when the front tire decides to come up whether you want it to or not!  | ||

Hey guy's has anyone done any research on a throttle that has less turn and more go, I wrote www.motionpro.com and told me to take some measurements and there might be a throttle and custom cables to get a less turning throttle, I had the billet quick throttle on my bagger I use to have and was nice, I want a quicker turning throttle but can not measure my bike till I get it back from the shop, I really liked the one from pingel it had the cable ends and top half of the throttle cam exposed and would shoot cable lube every once a month into it, it was not a 1/4 turn throttle which is really what I wanted but was less than stock, so I will be trying to get one and would like a 1/4 turn throttle, so if anyone knows of were I can get one or any places that sell racing throttles please let me know.

With big throttle bodies, a progressive throttle linkage becomes necessary because the bike can and will respond immediately (No carburetor bogginess). You'd think the direct throttle linkage would awesome, ultra-response and mega-power the instant you wanted it. It is like that, but it's not the dream date. They become almost unrideable at slow speeds and forget about throttle moderation in a corner. Imagine going around a corner, even gently, and having the rear step out because you gave it too much throttle, even though you really didn't. I've not ridden the 1125R, but this has been the case on other bikes I've ridden, and is discussed at length in books about fuel injection. I'm curious to see how the 1125R would behave with these mods. It has (relative speaking,) HUGE throttle bodies. Even an X1 with a stock (Very small) throttle body and a few mods gets super twitchy at low speed. Cornering is very close to throttle on-off-on-off-on, than a smooth power, with the "on's" being very very "on". It's fun, but it got old fast, for me, on the street. A perfectly round, 1:1 action throttle pull would, in theory, make the 1125R a very exciting animal. (Message edited by jos51700 on February 02, 2008) | ||

You might like it though. I'm sure it's different for everybody and that type of throttle response will float someone's boat. | ||

I`d be careful Bagger. We used them all the time on the smaller race bikes. You kinda loose your cruising range. It`s either on or off for the most part | ||

Too much too soon and too quick can be VERY difficult to moderate. The ST1300 has been accused of this as well as many other FI bikes. One thing yo may want to do on your stock set up is remove as much free play as possible and still have it return to idle hot and cold. Time2Roll Neil S. | ||

Of the "modern Big twins" that I have become familiar with in the past few years (RC51 SP1, Ducati S4 [916 engine], Buell XB12R), and still getting used to the 1125R... None of them are content at traffic speeds (15-20mph) with the exception of the XB12R, but that one would overheat and ping. Although with the proper approach they are all perfectly agreeable. Perhaps my biggest issue is that the 1125R and myself are still trying to learn how to speak with one another... At this point I cannot understand what it wants, and because of that it refuses to listen to me. Not to mention I have only been able to put around 200-300 "fun miles" on her (and that was during break-in)... the rest of the 1800miles is just commuting; 100miles hwy and 40miles street per week. Just 5 more weeks before I can go out and play... but if I am lucky maybe sooner. | ||

I have a trick and it is to take the play out that the throttle cables and it will stick at any throttle setting but return to idle with you hand, I have done this on several bikes when riding the hyway, it is like a throttle lock but it just holds it in place and you just roll the throttle off when you want to, I feel that there is to much throttle turning and will get this worked out in the next few month, I am very sensitive to everything on the bike and it has to be just right and I feel the throttle has to much turning to full throttle and some were between 1/4 to 3/8 would be good for me, but I agree with the careful in the turns thing, they have throttles with different cams so you can tune the throttle for the riding you want to do.

Safety Preachin' withheld. | ||
| Fresnobuell |
No kidding, Mike that sounds incredibly dangerous. Throttles snap back for a good reason. | ||

Pffffft, the first thing I did to my Shovelhead was remove the throttle return spring on the S&S. Been like that for 7 years now. Keeps my hands from going numb, never been a safety issue. I'd be more concerned with a non-linear or unexpected operation. Z | ||
| Baggermike |
What I do is the same as a throttle tensioner so I can just roll the throttle back to idle and I only do this on the hyway so I can take my hand off the throttle for a few seconds, I think Dark Horse products is making bar end weights and has a throttle tensioner built in that does the same thing, so you see it is not dangerous just clever, but on the r it is hard to get at, on the uly it is easy I just have it adjusted loose and then on the hyway I turn the free play out to the point that the throttle sticks but will still go back to idle.
