Is it me or is cruising below 4k RPM's a major task? What can be done to make the 1125CR more manageable below 4K? | ||

I have the 1125r and I'm questioning the need to cruise below 4k. Should you expect a twin that revs this high to run comfortably at such low rpms? I dunno (Message edited by samcol on June 12, 2009) | ||

Do you have the latest (12Z) ECM map? There is a computer program that will give you the option of the amount of fuel and timing the engine gets. Do a search...it's here for you to find. Mike | ||

Buy a 12r! Get the latest flash. Why do you want to cruise below 4k? Mine will run good from 2,500 on up. It likes 4k+. I just love 2nd and 3rd gear power wheelies. I was cruising in a 30mph zone in 2nd today. I let the pickup get away from me so I could play. The speed limit changed to 55. At 50mph I nailed it. Front end came right up and I caught that pickup. I decided the safer part of fun was to get both wheels on the pavement. 5 miles later at the stop light the p/u driver complimented me on the 60mph wheelie (he rides a Honda 600) This was his first experience with an 1125r, he was waaaay impressed!

I have the new flash and i think that it still has surging here and there below 3200k | ||

Johnny, how many miles are on your bike? These things are really tight new, and get losened up and smooth out as the OD turns. | ||
| Jdugger |
Personally, I recommend cruising at 5k-6k on the tach. The 1125r certainly has a "happy place", and in my opinion, when the needle on the tack points to the sky, things are "about right". | ||
| Xbswede |
Dude this is not an XB stop lugging the motor.1st and 2nd gear is about all you can get away with in the lower rpms. | ||

The 1125CR w/latest flash (12Z) is better in that RPM range (at least on my stock CR); but as others have said, it's not the "Happy Place". 12Z does help though with low RPMs. Also, as others have said, once the motor is broken in it improves. I try to stay 4k-5k when cruising for now. Regards, sleeper_777 | ||

Sometimes in town, I may putt along under 4k for a just a little bit, but not for long, and I don't try to accelerate. (Message edited by whynot on June 14, 2009) | ||

+1 on the flash. I have an 08 R and the latest flash made my bike much more manageable under 4K. In fact I did a 125 mile jaunt today and some of it was in traffic where at times I cruised at 2K with no stutter at all. Most of the time I romp on it like the tramp that it is and it just takes it without hesitation and keeps on going. I think I'm in love.  | ||

4k is not lugging the motor. I have found Loretta's sweet spot, 96 AFV F&R at 5000' elevation, inner air-box removed, OEM exhaust opened at rear chamber. I have no problem idling in first and second, thru my neighborhood. 1st is ~7mph, 2nd is ~13mph. 30 is about as low as 3rd will tolerate, compensator chatters a bit, but motor does fine. When this motor "learns" it is like an IL4 with torque. Z | ||

I certainly agree that 4,000 rpm is no where near "lugging the motor". | ||
| Fresnobuell |
It's not lugging, but sub 4,000 RPM certainly lacks throttle response and you are definitely outta the "fun zone." Unless one is forced to run at super slow speeds, why on earth would one choose to ride in that RPM range? | ||
| Johnnysunami1967 |
Wow, thanks for all the input...Yeah, most of you are right, why putt around at 4K, unfortunately I have traffic lights and traffic in general where I live...LOL. Yes I do prefer flying, but unfortunately there are times when one needs to slow down to gawk at the honey's...I'm thinking about checking out the 12Z map, but want to wait till I install my new HPE exhaust...Thanks to everyone who responded, very much appreciated! | ||
| Johnnysunami1967 |
Hey Badlionsfan, to answer your question, I have 5300 miles...yes you are correct, i recall when the bike turned over 4K miles, the bike seemed to be smoother...Thanks! | ||

Unless one is forced to run at super slow speeds, why on earth would one choose to ride in that RPM range? Why would one choose to put unneccesary wear and tear on a engine when they don't have to? I cruise below 4,000rpm every day without issues. '09 CR with the 12Z flash. I'm generally in 6th gear by about 47-48mph if I'm just out for a ride. | ||

I'm generally in 6th gear by about 47-48mph if I'm just out for a ride. I hope you don't ever have to take evasive action as by the time you click down 3 gears it will likely be too late. One could argue that you are doing more harm to the engine running like you describe then running it like the manufacturer intended. If there is one thing on the 1125r that people don't have to worry about, it's the Rotax engine. As far as I am concerned, it's bulletproof. Look at all the 1125rs being raced in the AMA and around the world...most of them are very close to stock. The mechanical DNFs are virtually non-existent. | ||

I hope you don't ever have to take evasive action as by the time you click down 3 gears it will likely be too late. So you suggest that I just sit around a 7 grand all day? And I'm not doing any more harm by running the engine slower. I'm not lugging it - it runs smooth, has oil pressure, etc. How exactly am I doing more harm??? Oh, and even at 4 grand in 6th gear, I can whack the throttle open and she still walks away at a pretty good clip. If yours doesn't, it must be broke. | ||
| Xl1200r |
Your new BadWeB handle is "SundayBueller". Hey now, I didn't say I run it like that ALL the time! | ||
| Zac4mac |
I do the same, Xl. The good side is I get a good long life out of my tires too. Most of my miles lately are commuting, so I try to be as smooth as possible. Although i usually go into 6th above 60 mph. Up in the hills riding the twisties is altogether another story. Believe me, I enjoy the ride. Ain't no grandma Z | ||
| Xl1200r |
Exactly. I have no need or desire to keep the rpms high when I'm making my way through town or down the interstate to get to work. I have no need to waste the gas going down straight country roads making my way towards the twisties. Once in the mountains? Yeah, I'll keep her up around 5k or so - other than that, I just cruise it. I don't feel the desire to beat the bike every mile. | ||
| Andros |
i agree with Johnnysunami1967. i hear more fuel and change of timing will help this. lets see if adding the jardine can and protune card will fix some of this choppyness... | ||
| Ccryder |
I guess I'm one lucky SOB! No real flat sections, straight sections and, only 2-3 miles worth of small time riding on my 70 mile one way commute. Yeah in "town" I'll cruise around at 3-5k but that's just because the slow parts are so short and the speeds sooo sloooow. Other than that, I get to play on TN back roads and I try and keep it around 4.5-6k in 3rd gear. Heck with all the LEO presence and twisties, that's all I need. A typical drive to/ from work I see 2-3 Sheriffs and at least one TN Trooper, not counting a local or 2 thrown in for good measure (Passport 8500 X50 is my savior). I do pick my points to "exercise" the engine and it never ceases to put an SEG all over my face. Yep this is one fine powerplant for street riding, maybe the track too but I'll let one of you other Buelligans chime in there. Later all Neil S. | ||

Thanks Ccryder, first of all I think everybody here who has posted on this is right. This engine after ECM upgrades is one of the most forgiving engines in terms of how you run it. It really does not matter what rpm's you like to cruise at. Yes it will accelerate faster and harder if you nail it at 5500-6000 rpm,s but will pull right away with moderate throttle also. Mine also goes through town at 1500 rpm in first or second with no problems. Now my sweet spot after installing my muffler system is 3500-4000 rpm,s, in any gear, when cruising JUST to hear the great sound I have. Not too loud, just really healthy. In town or out thats a great range to cruise in. Just humming along, sweeeet. At 9000+ rpm,s it sounds like Eslick or Higbee coming down a straight at any one of the tracks. This engine, basically stock, is awesome. Bob | ||
| Bcrawf68 |
Zac is right, this thing runs great at 2500 or so rpms in 2nd, 3rd 4th all day long. I try to keep it around 3000 or so in 5th and 6th so I don't elongate the main bearings. I live at sea level. | ||

I've been around hi perf engines most my life and the Buell Rotax is definetly one of them. It didn't take me too long to find out where the powerband is on the 1125r and it kinda took me by surprise. I didn't expect a large displacement twin to have it's powerband up so far on the tach. Its a very unique machine, with an intended purpose but I'm quite sure it can be used well below that purpose and handle it easy. I have a friend with an 08,4000mi and has never been over 7K on the tach,, he loves it! Like my grandma once said,"There's people, and then there's people". I have no doubt that the engine has been tested with a variety of users in mind. To me, it has a fierce powerband! Really something in a bike engine I haven't experienced before,, It is outstanding, I hope I never get use to it. | ||
| Buellfanatic8814 |
I..personally..try to keep the RPM's up past 4000, bare minimum. When cruising i've gotta be doing at least 80 mph just to even think about putting it into 6th gear. I'd much rather have the rpms up in the powerband(4500-6000). Anything below 4000 rpms at speed is not nice to the bike & it lets me know it. Very sluggish & it takes a bit to get it to prime operating range without doin wheelies or jammin on the throttle. Anything less than 55 mph i'm still not even out of 3rd gear..heck i've gotten it up to 87 mph in 2nd & it wasn't even redlined. There's 10,000 rpm's available & i use em all. besides peak hp is at the upper rpm range anyway. Luckily i'm goin to montana next month so i'll get to find out what 10,000 rpms in 6th gear is like  ...wheeeeeeeee..go fast..very fast.. Thanks, pete | ||
| Xl1200r |
Just because the peak power is at the top of the rev range doesn't mean you have to use it all the time. And if the bike feels sluggish at below 4,000rpm, I'll default to my previous statement - it must be broke. I have no problems pulling down under 3000 rpm at times in any gear and moving along at a brisk pace. This isn't doing any harm to the engine whatsoever. |
