959 Sprocket Change Speedo Reading

Discussion in 'Panigale' started by flatstick959, May 29, 2016.

  1. is it right if you fit different size sprockets the speedo is t effected on the panigale as the pick up is on the rear wheel?

    Thanks.
     
  2. No it won't be affected
     
    • Agree Agree x 1
  3. It won't make any difference if the sensor is measuring wheel speed, because the wheel diameter hasn't changed by changing the sprocket.

  4. Cheers

    Was going to put a renthal on just for aesthetics and might go to a 44t while I'm at it
     
  5. Yeah just wanted to confirm the pick up was off the wheel speed and not off the gearbox. Cheers
     
  6. Seems like a good idea to me!....

  7. Did you keep it 43 or change the size?
     
  8. Went up one tooth to give it a little more punch, but barely noticeable difference.
     
  9. Cheers that's what i was going to go for

  10. The standard chain is a 520 pitch right?

    Cheers
     
  11. Yes. The link I posted will take you straight to the correct (+1 tooth) sprocket.
     
  12. Cheers that's the one I got

    Thanks
     
  13. Looks better and a good deal lighter

  14. I know... The standard one feels about 4 times as heavy!
     
  15. I have a really lightly used 2 teeth bigger (pretty sure it's a 46) than the standard 899 rear sprocket that I can't fit because my stock chain doesn't allow it. What size have u put on as the 959 uses a smaller one doesn't it?

    The speedo isn't affected because the pickup is on the brake disc but if u change the tyre size it will change things

  16. Yes, the sprocket on mine is the standard size for the 899 (which is 1 tooth more than the standard 959 sprocket). Will it not fit if you spin the adjuster block round the other way?
     
  17. Actually, on the speed front I saw 160mph at 10,000rpm. theoretically the exact speed for that gearing at those revs is 153mph, so only a couple of % out, which you would expect.

    (Yes, standard on 959 is 43t, with 899 being 44t)
     
  18. Nope, the axle was all the way forward and when I put the weight on the bike it was like a guitar string!

    Here is the difference it made then putting the 44 back in....

  19. Going up 1 tooth meant I had to move the wheel in a few more. Prob 3 full turns of the adjustment bolt forward

    Chain wouldn't have been long enough to go up 2 teeth


    You could try going down 1 on the front instead, this will make the chain slacker.
