    On the trip to Baja this weekend, the GPS logged a top speed of 118 mph with a 16t. (Didn't have time to check what the speedo was reading.) The bike had a bit left, but the next corner was approaching much too quickly.

    17/45 work without new chain... you have to mount the rear chain settings... reversed...

    KTM don't make original 44 sprocket... but other company does... and cheaper.. http://www.pbr.it/

    No the 525 chain on the 950 is wider than 510 on LC4, the sprockets are noticeably wider....They may mount the same, but they are not the same size sprockets...

    As far as I know, only Stealth makes the alluminum/steel sprockets.

    http://stealth-america.com/


    ON this site:

    http://www.supersprox.com/listy.php?type=ktm

    They list one for the 950 in 525, part #: K5110010 from 38-52 teeth.

    I suspect that sprocket bolt paterns are standard, and that any 525 stealth for street bikes would work fine.

    BTW...I'm pretty sure the LC4 etc. use 520, not 510 as I indicated previously.

    My bike is dead stock except for the 16t sprocket and I got an indicated 128mph in 5th and 6th before it ran out of steam. The front end was pretty unstable feeling at that speed and I only ran at that speed for aprox. 10 miles this was in western Kansas, real flat good road, and the bike had about 2600 miles on it at the time.

    About the Stealth sprockets....

    I ordered one for the Husqvarna Supermoto and what came in was one of the "streetbike" style sprockets. That's probably what you'll get for the 950 also. I really liked the slimmer look of the dirtbike sprockets, but with several thousand miles on it and no appreciable wear I'm not complaining!

    Go to this site and download a gearing chart. It allows you to enter the relevant details of your bike and see the differences in changes to your gearing.

    Gearing Chart

    For your information the ratios for the 950 are as follows;

    primary: 1.91
    1st: 2.92
    2nd: 2.13
    3rd: 1.72
    4th: 1.35
    5th: 1.13
    6th: 0.96

    Then the combination of the front and rear sprockets.

    Good luck

    Yep. It's excellent.

    I've put in the values for the 950 and - suprise suprise - it confirms the stock gearing being way too high. Given that 99% of the 950s deliver peak power at 8500 RPM (mine does too on the Dyno) 17T vs. 16T looks like this:

    On 17/42 in 6th at 8500 RPM: 236 KM/h or 147 MPH No way... :D The engine won't come near 8500 in 6th
    On 16/42 in 6th at 8500 RPM: 222 KM/h or 139 MPH Still high but a step closer to reality.

    :rofl

    It took all of 2 minutes to install the thing. But I am too lazy to be putting it on and taking it off.

    On another note, I have been trying to figure out if the mudguard has any effect on wind buffeting since it more or less eliminates the flow of air up the forks and thus should be creating a larger vacuum behind the windscreen. I haven't been able to tell much difference, however.

    Reading back over this thread I have been reminded of an experience I had as a wide eyed 14 year old.

    I was out with my brothers God Father who just happened to be a Ferrari fanatic. We were on the way to a Ferrari Owners Club meeting and in his 275GTB 4 Cam Long Nose, a 1964 I think. Anyway, on the blast along the M4 he commented on how close the gearbox ratios were but also that when in top gear the needles of the tacho and speedo moved in unison. The fact being that at max power you are at max speed, in effect a 1:1 ratio.


    I have always remebered this and felt that as times have changed we now loose this ability to judge a vehicles gearing as most bikes now come with either all digital dashes or a combination of analogue and digital.

    Nevertheless, my point really is just that, should we try for max power at max speed? Or are we chasing a Holy Grail? Maybe it is a case of how and where you ride rather than what the perfect gearing is...

    Im thinking out loud you know. ots saturday, beer, football...... :freaky

    Sure, here you go.

    Based on my experience with 16/42 I think that 16/45 is uneffective i.e. too low if you use your bike on the street too. I'm sure it will feel 'spectacular' alright. Freaky short gears with the engine ripping through it like a maniac. But I doubt it will be an improvement. You'll be dancing the gearlever more than on 125 two-stroke. :D The very short bursts of power will be un- or at least less controlable too. With the proper mods the LC8 engine has quite a bite on a high(er) gearing already I'd say.

    You can remove 1st gear altogether and on every stretch of tarmac or highway (you do encounter these every now and then...) you'll be revving and buzzing along in a very unnerving way I think...
