    Hi guys

    Just a quick one. What size rear sprocket do people find the best for general track use on the 2008 onwards CBR1000RR. I seem to be running quite a big rear sprocket at a 48 I'm thinking a 46 would be a little better, providing a quicker acceleration off the turn.

    What do you guys think?

    48!!! WTF.. standard is 42, so if you go down teeth at the back, it will reduce your acceleration, not increase it.

    I knew that size would be miles out. I'll stick a 46 on there and see what's what.

    At 48 your chain must be huge! Down 1 at the front on a gearing commander shows the equivalent rear at plus 2.8 teeth so you'd be better going down 1 front and up 3 at the rear.
    After 48 your gonna miss the punch!

    Haha. Should be quick off the mark with no top end on that gearing.

    Wonder if it's a cbr600 rear sprocket instead of a thou? Should be mad that gearing so if you say its slow.. Can't be. Proper 1000 sprocket

    It's defo for a 1000. Thing is my last two bikes were making approx 200hp at the wheel. I'm finding it hard to adjust to the 35/40hp loss. I guess that's why it has no punch.

    14 44 for me .. Wheel base sits nicely at 210mm.. That's the magic number I've been told
