Dose anybody know if there is a thermostat on the cooling of one of these new 1125Rs. I ride all through the winter, that is why it would be important to me (not on my XB12R at the moment due to its seriously unreliable engine – hence the interest in the new bike, Don’t get me wrong, I still love the Firebolt). It seems obvious to put one on, I could be wrong though. Also dose anyone who has actually seen one of these beauties in the flesh recon there is room under the screen for a navigation system (about the size of a largish mobile phone)? It’s difficult to tell just through pictures. Cheers….Fulgur. |

There will have to be. On a water cooled motor there is such a thing as too cool. With a motor that isn't up to operating temp you will see poor combustion, the oil will never reach proper temp, etc. |

Dam! - just read about the thermostat on another thread - sorry. Thanks anyway Spiderman. |

Another one - is there hazard lights (where all the indicators/turn signals flash at the same time)? ....Fulgur. |

I realize I'm late on this thread but I do have some insider info on the thermostat issue...yes there is a thermostat in the bike. It was designed and will be produced in MA. I will work on trying to get some of the manufacturer specs on it - I happen to know the engineer that ran the development project (I used to work there). |

TIP: Drop 30 degrees on the thermostat an it will run better !!! IN BLASTing LaFayette |

"Drop 30 degrees...." No, no it won't. The fuel and timing maps will be way off. They are optimized for the intended operating temp range which is determined by the thermostat spec, fan toggle, etc. It WILL have some self-adjusting operating range because it's a closed-loop EFI system, but not THAT much [15%]. |

The computer has a broad enough range to compensate for this ... "PLUS" as "i" said it will run better ... Engine oil will run cooler where as it does not break down as fast ... Engine will last longer because it runs cooler, 100K plus ... Water pump(seals/hoses) will last longer ... In BLASTing LaFayette |

OK - have it yer way. Buy one, change the 'stat to a 160, burble and fart yer way all over the land......but don't take it to your dealer looking for a 'fix' let alone warranty consideration. And, BTW, synthetic oil [the recommended lubricant] doesn't 'break down', care about temperature, or much of anything - it's "synthetic". This is all much ado about nothing in any event. Other than cold weather conditions, the thermostat is going to be wide open anyway once the bike has run a few minutes and the operating temp will depend on load and the heat-rejection capacity engineered into the cooling system. In other words, 195-200 degrees. |

One tip as we move into the world of water cooling. Modern water cooling systems run the water temperature quite high with a commensurate increase in system pressure so boiling does not occur. The reason for this is that the water temperature inside the motor is still very cold compared to the heat coming off combustion, and higher delta T (difference between ambient and coolant temperature) increases heat transfer out of the radiators. Water temperatures of 220 and 230 degrees are now quite common when engines are at high output. |

Doesn't water boil at 212? Or is it the pressure that keeps it from boiling? |

Yep, the prior anony and Spidey are right that both of these help, and pressure alone makes a huge difference. With modern pressurized systems even pure water won't boil until 250-260 degrees, and with higher pressure caps, even more is possible. One of the reasons auto companies went to red yellow green on gauges instead of numbers is because people were panicked by the numbers they saw as systems went to higher pressures and temperatures. |

nice going Anony's now there all going to start looking for larger air scoops to cool there motors......

Delta T Another reason why a hydrogen fuel cell powered passenger car would need a radiator the size of a Mac truck. Never has reading all of the technical stuff about a bike made me want one so much. Go Buell! |

Nice - thanks. and the hazard light situation anyone. I ride in cold weather and traffic so both these points mater to me. Ta......Fulgur. |
