    Front forks want to see one working??

    Front forks want to see one working??

    I posted some dyno charts of the Sachs and Ohlins rear shocks, one thing of note is how fast do the suspension parts move, and how far.

    While this is a BMWS1000RR, the forks work the same way.

    I found it interesting the amount of time the forks do go to the bottom or near the bottom of the stroke, as well as how slow the forks move.

    This was done at Sears Point Raceway 11-01-10, lap times that day were into the 1:42's

    It could be the wide angle, but those forks sure do look like they have a wide range of travel.

    Imagine how much better that video would be if it was the sound of a V4 instead of the Bimmer =)

    Thanks for the post Dan.

    The travel is 130 mm. 10 mm more than most forks.

    Well you never know what can happen.

    If I sit on my head and watch this, it makes more sense...
    Couldn't you flip it around 180 degrees in post-production ?
    Jeez Dan !
    But seriously, forks look like they work well. Nice !

    Seeing the forks move as much as they do going through the carousel (~2:45+) is pretty cool. You can almost "feel" that bump on the exit.

    I'm not a big believer in letting a bike idle/warm-up for too long, but I think he let the clutch out before the starter disengaged!

    That's why the laptop is nice.....I'm too lazy for trying to save and edit the video, so just flop the laptop up on it's side and everthing's swell.

    Awesome video, though. Really shows how hard a fork is working. Granted, you wouldn't be going as fast, but imagine what a fork goes through on a normal back road scratch.

    Last weekend I was at Mugello (Italy) and recorded this clip.
    It's late afternoon and the sun is low, so it's sometimes quite challenging for the video equipment.
    Codec is DivX/XVid, so VLC can play it.
    R7 (ex RSV4F aPRC) on track, Shiver GT on road.
