| Moto2 Contender Joined: Oct 2007 From: Pullman/Spokane, Wa I Ride: 2007 BMW F800S, 1999 ATK 605 ESDS/SM, 1978 Honda PA70II (hobbit with kit) | BMW forcing new S1K owners to 9000RPM redline for 600 miles yeah yeah, I made a thread other than that old one. This deserves it's own topic. I've just found out that BMW is not releasing new S1000RRs from the dealers until a new fuel mapping has been delivered to the ECU. This will lower the redline to 9000RPM. This will then be removed when the bike hits around 600 miles. Not quite sure what to make of this...I don't think it's that big of deal but it could point to a few things. 1. BMW is simply wanting to enforce engine break in. or 2. BMW has already gotten warranty complaints on the engine (I haven't heard of ANY so I don't think this is likely) so they are using this as a precaution. I've never heard of a manufacturer enforcing breakins like this. What say you? Personally I don't think it's too bad. You can still go like a bat out of hell to 9000RPM, and putting 600 miles on a bike takes 1, maybe 2 days. discuss, and please keep the hating aside, this is new ground for manufacturers. Will we see others follow suit? |

now, to answer your question, according to you, this is the first bike in the history of the world that has the software to enforce such things as a variable red line...so it makes sense to not do it before now. but, it sounds more like a CYA maneuver to me than a proper break-in procedure...keeping the bike from peak horsepower for a few miles as users get used to the bike is probably a good thing. from an engineering standpoint: it's more things to test and to have go wrong...it's gotta be a legal/marketing thing Last edited by koorbloh; 03-02-2010 at 10:37 AM.. | |

Anyhoo, I think its a smart business decision, given that the capability to enforce it is there for a few reasons: (a) prevents the number of returned failed engines they are gonna see = less warranty costs and less bad press, (b) likely reduces the number of noobs/non-noobs that kill themselves on the bike straight after they buy it = less bad press, (vi) haven't thought this one through yet. |

It wasn't a "forced" redline, but when the car was new the tach would flash yellow and red if rev'ed too high. Even after break-in, the car still did that until it was fully warmed up. Great idea, since warm-up is especially important for high performance engines. The best way to break in an engine is on the dyno. BMW's engine doesn't do anything different than every other engine on the market. An engine is an engine is an engine. ![]() Last edited by theJrod; 03-02-2010 at 11:05 AM.. |

![]() ![]() Joined: Jun 2007 From: Portland, Oregon I Ride: naked | In the past, I've heard that BMW has done the same exact thing on their high-performance car engines. ECU is programmed, during the break in period, to only rev to a certain mark, once the odometer clicks past that point, full engine potential becomes available. A good source, that has ridden one, tells me the bike is a beast. I want to ride one now. |

All bikes need is a good 20 mile break-in. Then change the oil and run them hard. Think about it, every engine is put on a dyno at the factory to ensure that they don't have any defects. |

| Pit Crew Joined: Apr 2006 From: Seattle, WA I Ride: Too many | Aprillia did the same thing with the RSV for a long time. Didn't require an ECU reprogram, but the effect was the same. Since that bike liked to drain batteries, most owners got good at the button-dance that reset the rev limiter. I'm sure other manufacturers have done the same, this was just the first that came to mind. So as far as manufacturers "enforcing" brake in rev limits, there's one example that's over 10 years old. Welcome to the party. |

I would guess that they have found something in durability testing that they feel the need to take the extra cautious steps. I would also guess that there is no way in hell that they allow this bike to get a rap for failures. |

And I would suspect the next 'batch' of engines will be tweeked a bit to address that weakness. But like mentioned above, this is hardly ground-breaking. | |

actually thats the first thing i thought. After seeing what people are doing to them after they get their hands on them lately. Maybe not exactly what they anticipated happening to the engines has shown reason to go ahead and impliment that sort of action. Otherwise why didnt they do it up front. | |
