Starting this thread to move this discussion away from the Price Increase thread. Due to the lower gearing, the CR will get off the line quicker, and accelerate harder. HOWEVER, the taller gearing and better aerodynamics of the R will allow it to run to a higher top speed, thus the "R" is faster, but the "CR" is quicker. Understand? |

I got ya! makes perfect sense to me! I'd prefer "quicker" myself. |

yeah right. Throw in reaction time and track conditions and ............. oh yeah contact patch ;+) |

O'My god, are we this dumb that you have to start a thread to explain the difference?

'get off the line quicker' - in theory maybe but my race experience, where getting off the line is paramount, is a little different. I often choose to use 2nd gear (and my gearing would be optimal for the track) this cuts down time wasting wheel spin and use of the clutch can optimise the torque sweet spot. When you do get to change gear, wheelspin or wheelies are less of an issue. It would be interesting to put a R and a CR side by side on a less than perfect surface or on wet tarmac. |

OK ...... But do not forget that the CR puts down 8.5% more torque to the ground then the R. This is in the entire rev range and at every gear considering the engine and trans gearing are identical. Now I don't want to spark a R vs. CR war that would be ridiculous so I'll say this about the R. It's aerodynamics and overall top speed may more then make up for gearing in a straight up race against the CR. The best way to find out is to get two monkeys on two bikes,(cr&r) and go for broke. |

Where do you get those figures? From EVERY article I've read, the only difference between the two models is the gearing and the front fairing. The engines are in an identical state of tune. |

Off the line, the R is pretty incredible, reaching 60 in under 3 seconds. I don't know about you, but this is quite enough for me. If the CR is quicker, that's great, but every time I open the throttle from a stop on the R, I'm always awed... maybe on the CR I'd be shocked and awed... |

Jaimec - the gearing at the rear equates to an approx. 8.5% difference between the two bikes in favor of the CR in terms of acceleration. The trans gearing and the engine are identical I stated that in the previous post but maybe I didn't write it clearly. Pariah - LOL @ shocked and awed |

WRT the Shock and Awe... I'm kinda generously proportioned, (think Kung-Fu Panda) and usually have no problem keeping the front wheel on the ground. At WOT in 1st, after about 7k I cannot keep the front wheel on the ground. It is fun...! R |

I'm for both quicker and faster. I'm into full time racing with my R. I want to be quicker out of the corners so I can go faster down the straights. That's how slower bikes win. It involves more than just gearing and I'm working on that too. I will say that I am getting the chain drive so I can be quicker out of the corners and faster down the straights. BTW I don't care if the front end comes up easy when you jam on the throttle. That's for a different type of rider. Clutch-less shifting and a steering damper take away the radical front end lightness that I would be concerned about. Great holiday discussion. |

Wouldn't the only way a steering damper could remove front-end lightness were if it were made out of LEAD?? |

The engines are identical, but things like transmissions, final drives and primaries act as torque multipliers, so the CR does have an advantage there. I'm not sure it means much because the difference in gearing between the two bikes is about an entire gear (CR in third is appx the same as an R in second), but I do know I prefer the CR gearing on the street. |

Coming off an XB12Ss, the 1125R accelerates PLENTY hard for me. And I prefer the "weather protection" of that hammerhead fairing the "R" has. Top speed doesn't mean anything where I live... but the taller gearing and better aerodynamics also mean better gas mileage, too. |

I sort of wonder, with the CR being reviewed and accepted as being "sorted out" after the 08R, that the _CR_ ends up being put to the track/races. |

All chain driven bikes I've ever owned always got the sprockets replaced with shorter gearing. Most bikes are geared too tall from the factory to meet EPA noise restrictions. Even on the track I don't find much use for speeds over about 120 (Road Atlanta excepted). Just did Jennings on Saturday and top speed (GPS calibrated speedo, not optimistic stocker) was only 115. Stock gearing on my bike would top it out at about 160. With my gearing change, top speed is about 150, but I can acclerate out of a turn much better and I don't have to keep the engine wailing at redline all the time. I've ridden the R and it felt really good, so I can't see why a gearing change was needed, but I guess that's why Buell pays the engineers. |

Jaimec, when coming out of fast turns if you cross a ripple or pavement line at full throttle you will get some front end lift and a certain amount of head shake. At 100 this can give a new rider a little thrill. It's because the 1125 has enough power to make the front end light. A steering damper takes care of this little problem. Actually you should try it. It's a gas! Chad, even on our little technical track with only a ~1800' straight I can get to 130 with stock R gearing. If I could lower my gearing I would have greater pull coming out of the corners and more speed on the straights. End of January I'm going to the WERA race at Vegas where the straights appear to be a little longer. There it would still be great to be able to taylor the drive coming of the last turn before the longest straight. You know the Ducati's are doing it right. Obviously it all depends on what type of riding you do. I agree that the R would be more fun on the street with the CR gearing. If I was still using my R on the street I'd want the CR gearing too. It's just too bad we don't have an easier way to manipulate our final drive. But of course that's where the chain drive comes in. |

Doug, face it - like any sportbike, it's geared too tall for just about ANY course in the USA. Higbee here at Willow couldn't even get to 6th gear in a race except just at the end of the front straight. When he WON with the stock gearing, Eric Nolan (racing the 1098 for ProItalia) said he didn't want to see Higbee with lower gearing or he'd NEVER catch him... and Shawn changed the gearing with the chain and NEVER lost a race by less than 6 seconds after that. Vegas NEEDS MUCH lower gearing. I'm sorry to say I'm not going to be ready to be out there in January. You're gonna like the course... except it's freaking F..L..A..T (my profile pic was from F-USA in Vegas a few years back) (Message edited by slaughter on December 30, 2008) |

Steve, understood. At Arroyo Seco I get well into 4th on the longest straight. That's why I'm eventually getting that chain drive setup. It's true we have lots of torque coming off the corners but I know we could handle more. Would rather be getting into 6th with even more pull off the corners. BTW I was told that Arroyo and Vegas are very similar. Vegas is just Arroyo on steroids. It is unfortunate that you won't be at Vegas. I'm sure you're chock full of wisdom for that place and racing in general. Lisa and I do plan to make it to Willow some time this year and we'd certainly like to meet up with you guys then. BTW I do think that the R guys wanting to upgrade to the CR gearing are right on. For the street it would be so much fun to have all that pull. But it will make it a lot harder to keep it on the ground in front of the law! |

My lap times are as follows: Barber: 1:50 Jennings: 1:32 Nashville: 1:14 I can't recall my times from Road Atlanta, I'd have to consult my lap timer which is boxed up somewhere in my track gear. I'm not fast enough to race, and I typically ride Intermediate group. I tend to be about mid pack in intermediate. Some folks faster than me, and some folks getting passed by me. |

respectable times Chad. let's get faster this year!! all the best to you and your family this year. i will try to get up to Nashville this year to run that track with you. See you at Barber? tim |

Would love to have you come run Nashville. You need to get on the STT website and book the track day under the lights. That was awesome last year. It runs from 4pm until midnight. A real good atmosphere. People grilling out. Lots of families there. It was great fun. As for lap times, I figured out a long time ago that I'm not, now will I ever be Mat Mladin or Valentino Rossi. No trophies are handed out at track days. I just go out and have fun. Sure, I'd like to get faster, but I think at the point I'm at now, I'd have to push a little harder than I'm comfortable with to get faster at the risk of wadding myself or my bike up. I'll just keep on having fun passing a few folks, and getting passed by a whole lot more. |
