Zitat von M3M im Beitrag #1 So called "Sag" cannot be set up as such. It is a function of the preload setting. Preload can be altered on the R1200RS by selecting "one rider", "two riders", with or without luggage. See pages 73 and 74 (for the R1200RS) of the users guide.

This video from Touratech describes setting the sag on an adventure bike but applies to our RS bikes as well. We have 140 mm of travel on the stock RS rear shock so setting at 30% sag as they describe we should have a number around 42 mm of sag. Measurements should be calculated when just out for a day ride loaded for that ride as well when loaded for a trip. If we do at the 1 helmet, 1 helmet plus luggage and at 2 helmets we get the sag number for each of the settings. From there we can determine the one closest to our ideal number and use that vs what BMW sets at their 3 points. At 229 lbs in full gear and 15 lbs of luggage on a day ride I use the 1 helmet plus luggage and when on a trip packed for a couple of weeks I need to use the 2 helmets setting. So I never ride with the one helmet as the sag is too much. |

so to determine static sag, the front end is lifted off of the ground |

Zitat von M3M im Beitrag #7 The process for the rear is the same except you generally measure the distances in the vertical; the travel is the same. Are you sure there 4 positions mine only has 3, Rider, Rider+luggage and two up. As there's no ability to independently control front and rear so I wouldn't worry. Bill |

I’m not certain you can even make an adjustment on the front sag on the RS bikes. A suspension specialist can but don’t believe we as riders can. The 3 positions with helmet, helmet and gear and 2 helmets is for the rear sag only as far as I know. The Touratech video also shows how to do the vertical measurement to determine and set the rear suspension. |

You are asking for info on the R1250RS, which is different to the 1200RS. Bridgestone 175 Hurricane Scrambler - Royal Enfield 250 Crusader - Norton Atlas 750 (two) - 25 years - F800ST - F800GT - R1200RS - R1250RT |

It is what it is. Did BMW promise you it would be customisable as standard?

Zitat von M3M im Beitrag #11 it's a touring bike not a race rep so BMW chose not to accommodate this in the design stage as most owners seem to be happy with the presets not sure if the new R1250RS has the "auto" mode I saw on the R1250GS. This has the manual mode with presets just like my R1200RS but it also has an auto mode which offers a self levelling function to the preload. I used to own a Triumph Explorer that had electronic WP suspension. This had a much wider range of settings inbetween "sport" and "comfort". Whilst the suspension was superb, the bike had too many flaws to be a keeper. |

Quite a few things are wrong with me, but I don't usually spend many thousands of pounds on a new bike without researching it's specifications and features - I don't order one and then complain afterwards that it's features don't suit me
