My CR will get right on up to indicated 135, and I haven't kept it wfo for all that long, but it seems like any more speed would take quite awhile to achieve. What say the rest of you CR'ers? | ||
| Brumbear |
no clue I hit 130 on accident I wasn't even trying | ||
| Froggy |
Top speed is approx. 156mph depending on tire wear and such. That is bouncing off the limiter in 6th, and it will do it. | ||

I just tiped 150mph indicated on mine, still had more to go. I didnt have a gps at the time so not sure on actual speed. The bike had maybe 700 miles on it at the time and tires were like new. | ||
| Duphuckincati |
So Froggy, about how much road do you need for that? | ||
| Carbonbigfoot |
Man, you need to check your throttle position in the diag mode and make sure you're getting WFO... Personal best of 146, and it was accelerating like a raped ape still! My leather jacket starts to flap about 100, and it was beating the shit out of me. If yours is running out of steam @ 130, there is something weird. Rob | ||

If you can measure your tire diameter, you can put it into the calculator located here along with redline rpm to get the theoretical top speed: http://www.badweatherbikers.com/buell/messages/290 431/421365.html The diameter will increase marginally when going high speed due to the tire stretching from centripetal force, but it probably isn't enough to have much effect. | ||
| Nillaice |
or is that Centrifugal force?  i guess i all depends on your frame of reference  | ||
| Kevin_stevens |
Centrifugal. Centripetal is the inward force resisting the expansion. KeS | ||

DuBLEEPcati- are you running with your inner airbox cover on or off? If 'off' that would explain your bikes reluctance to pull past 130mph. I used to run my R with the inner cover off and it had a hard time pulling through 150mph. I put it back on and straight away it pulled over 160. Just a thought. | ||

Actually Centrifugal force is not really a force at all. What's really happening is that the rubber in the tire tends to go in a straight line, just as all other objects in motion as explained by Mr. Newton. This motion would tend to take that little part of the rubber in a straight line & hence increase the radius from the hub, however the centripetal (inward pulling) force of the rest of the rubber around it will keep it going round & round the wheel (fortunately for us). So you see.... there is actually no real centrifugal force, rather just the momentum of the rubber causes a perceived outward force from the perspective of the center of the wheel. | ||

Actually...it does exist...even though, there's no such thing. There's been great a debate about its presents in the last few hundred years. Here's one formula - Fc = mv2/r, where Fc = centrifugal force, m = mass, v = speed, and r = radius. An object traveling in a circle behaves as if it is experiencing an outward force. This force is known as the centrifugal force. It is important to note that the centrifugal force does not actually exist. Nevertheless, it appears quite real to the object being rotated. For instance, a child on a merry-go-round is not experiencing any real force outward, but he/she must exert a force to keep from flying off the merry-go-round. The child believes that he/she is in an inertial frame of reference, when in fact he/she is not. An object traveling in a circular motion is constantly accelerating and is therefore never in an inertial frame of reference. Since the centrifugal force appears so real, it is often very useful to use as if it were real. The equation above shows that the force depends on v-squared over r. Because v increases with radius, the force will actually increase with radius as well. If you are standing on the merry-go-round, you will have a harder time staying on as you move further away from the center if the merry-go-round rotates at a constant speed.

I didn't even think about the airbox cover... Huge effect when you get over 80 or 100. I usually run with it off, cause I don't spend a whole lot of time at those speeds.... R | ||

Clearly my comments were going to lead to a bunch of matter-of-fact statements from people trying to prove that they are smarter than someone else. Yeah, centripetal force points towards the center of rotation. Centrifugal force is the term used to describe the outward inertia of an object going around a curve. I knew I could have just said the tire gets bigger because it spins fast like the back tire on a top fuel dragster, but that would not have inspired the enlightened to chime in. Or maybe it would have inspired them even more. | ||

True - if you'd made a general statement about tire expansion it wouldn't have been an issue. But if you're going to use specific terminology, it helps to use it correctly. Fundamentals of communication. If you'd posted that the axle should be torqued counterclockwise to remove it, you shouldn't be all bent when people correct you; why get upset here? KeS | ||
| Ron_luning |
The axle should be rotated counterclockwise to remove it, if you're looking at it from the right side of the bike. Same difference. | ||

More than 100mph and I don't look down. I estimate I have gone eleventy billion MPH.  | ||
| Blur |
I've been around 130 a few times but don't feel real comfortable until I get a damper. Not having wind protection and a damper is too scary for me on the street. It was still pulling VERY hard. | ||
| Carbonbigfoot |
More than 100mph and I don't look down. I estimate I have gone eleventy billion MPH. Oh, YEAH??? Well I did the Kessel run in less than 12 parsecs! R | ||
| Brumbear |
So Froggy, about how much road do you need for that? Not all that much I ran up to a buck thirty in the blink of an eye I was tired and heading home from HH5 hit 287 in jersey laid on the tank was in 6th for the first time backed OFF the throttle after a few seconds I noticed everything just zooming by I glanced down 130 indicated I slowed right down but man it got up there effortlessly I swear | ||

I was really trying to be legal today since there's extra CHP's out around here for the hoidays, but man when I went to pass 2 cars in the first available passing zone, suddenly I was in tripple digits, first time on the 1125 for me since I'm still in the break-in. Seriously, I thought I was only at 80 (I came up from about 45) but sure enough when I got back in the right lane looked down I was past the century mark & quite honestly did not try to get there. This thing pulls like crazy! And is super smooth doing so! All below 6500RPM  (Message edited by ekunyvan on November 27, 2009) | ||

Clearly my comments were going to lead to a bunch of matter-of-fact statements from people trying to prove that they are smart er than someone else. Just be glad you are not trying to sell a new Buell to the bunch and hoping to make a reasonable profit, and hoping your service department can get some work other than warranty.  ~jammer | ||

i guess i started the wole nerd tandem. -sorry- it was a matter of time until it happened. that's just how we roll 'round here. -speaking figuratively- don't get your panties in a bunch about it. wikipedia is just a few clicks away, so don't think we is sooo much more smarter-er than yew. ya nowed enuff to use a simuler turm. i gev u haff credet | ||

Jammin', Man, lighten up. You have been posting your frustration in a lot of areas. Most people here are your friends. The fact is that most H-D dealers absolutely sucked at selling and servicing Buells, and didn't give a damn about their Buell customers. Something like 75% of them voted that killing Buell was a good thing. So don't expect to convince people here to think of the dealer network kindly. You have already risen far above the crowd, and that is good, as it has sold and will continue to sell Buell riders on coming to your store and making you money. Which you have earned the right to get for doing a good job. Accept that you won't convince everyone. Some are too far away, and some have been burned too many times. Some are riding the temporary wave of H-D and most dealers dumping Buell stuff. Also you can bet a lot of Buell riders are going to dislike H-D for a long time, maybe most forever. You can either try to convert them or accept that they have good reasons for their feelings. It will be tougher than ever for them to walk past that orange and black shield. The fact that so many still do is testimony to you and your store specifically. We like you! | ||

ok so i have a 09 R but here is mine. i have hit an indicated speed of 184mph and she was still hauling, not as hard but still pulling to redline. this was at around 6200 rpm or so, hard to tell at that speed. oh, and just in case, never ever close the throttle at anything over 130.....its slows scary fast, as if you grabbed a hand full brake. i have the inner air box lid removed and she pulls hard to about 145 then you can feel it slow down.

We went out for a good ride yesterday and I had several opportunities to twist its ears . nowhere near top speed but 3ed pulls like crazy to redline and shifting to 4th is insane. My problem is my textile pants are too slick I cant stay in the seat. I like to ride up close to the tank, and I have the high bar conversion, I can barely hang on , if I slide back the front starts coming up at about 8k rpm. I need a backstop or something  | ||
| Xtreme6669 |
Prophet, are you sure your bike doesn't read in km? no way it would hit 184mph w/o some work and gearing. You may be a bit out of calibration on the speedo! | ||
| Froggy |
Removing the inner airbox will reduce top speed. Also, top speed on the R is approx 170mph according to a gear calculator, Indicated might be a little higher, but there is no way you are getting 184mph on a stock bike. Also, 6200RPM is 100.5mph in 6th gear. | ||
| T_man |
Yep - Froggy your dead on. I find myself cruising at 6k / 6th gear on long trips and it nets 160km/h on the head. 6200rpm would equal very close to 184km/h. My R will pull 262km/h in top gear near redline. |
