    I just acquired an 09 Stelvio that has been lowered.
    The fork tubes have been raised.
    What is the oem height?

    Not sure if this is what you're after, but 198mm (or close enough to just under 8 inches) from the bottom of the clamp to the bottom of the metal part of the stem.[​IMG][/IMG]
    This is on a 2012 model.

    I will check against your measurement.
    How about above the triple clamp?
    Thanks.

    That is easy to do.
    Thanks for the great site.

    Be careful with that one. It won't sit flush on top as the top triple is not machined at the same angle so if you put the 12 o'clock position flush, the 3 o'clock won't be. They come stock from the factory with a set exposure above the triple clamp. My 2012 sits about 16MM at the 12:00 position (from memory but I am not that far off, I can measure it if needed). My friends 2010 also sits above the triple but not sure of the amount. All things being equal, a few mm here and there won't affect the dynamics tremendously, but they don't come flush from the factory. Perhaps someone with a pre 2012 can comment. There should be something on the site also about this.

    On this subject, what is the riding impact of lowering the front end by clamping the tubes at say 20mm above the triple tree? Has anyone experimented with front end ride height?

    Raising the tubes will reduce the rake and trail. The good news is it will turn in quicker and turning in general will feel lighter. Downside is you will reduce stability of the front end (ie. more susceptible to tank slaps) but no idea at what point that will occur. All depends on the design of the bike. That being said, I have seen Stelvios with the forks more than an inch above the upper clamp. The rider is still alive so must be ok????

    I do on all of my bikes. Raising the forks in the triples almost always makes things better. Rake has to be quite excessive in order to cause issues. My Jackal is radically different then delivered since I swapped to the V11 Sport front end, and there's zero need for a damper that was put on by the factory to lessen speed wobble issues with the very relaxed stock rake. I pull 10mm at a time, usually ending up at 20mm. I don't think the Stelvio would be much impacted by this... However, my Stelvio now wears a custom-built 3.5x18" front wheel with 120/70 front tire profile, so I left the forks in the stock position (for now). It rocks.

    Raised em up 18mm to flush at the inside.
    Now the bike actually leans when on tbe sidestand.
    And only 20 nm torque on tbe pinch bolts.
    Bet these get overtightened a lot.

    Lifted my Forks as far as they would go, to drop the front end (and the seat height!).
    Much better feeling, I like my Bikes to be as 'lively' as possible.
    No way you'll make a Stelvio unstable whatever you do, the Forks can only be raised a certain amount before the waisted section of the Sliders enters the clamp area anyway.
