    cbr 250 rr revs/speed

    Hey, just wanted to check to see if my bike is pulling the same revs as everyone else's CBR. ok,
    4th gear 50kph = 6,000rpm
    6th gear 100kph = 9,000rpm
    6th gear 160kph = 14,000rpm

    5th gear is 1,000rpm to 10kph (eg 100kph = 10,000rpm, 90kph = 9,000rpm etc.)

    Please give me feed back to see if they are all the same amongst different models.

    P.S my cibby is a 91 RR MC 22

    They are different among the models. Internal gear ratios changed.

    Sounds OK, as two seven said, they change though.
    To every man upon this earth
    Death cometh sooner or late
    And how can a man die better
    Than facing fearful odds
    For the ashes of his fathers
    And the temples of his Gods

    Depends on your sprockets. Sounds almost the same as mine except for 6th, at 110km im sitting on 10krpm 120=11k 130=12k etc etc, lower down it matches closer to yours, so i guess we got different gearing, UNLESS, wait a sec, how much you weigh... I mean.. WHAT!? you did 160km? sorry officer, i won't do it again officer

    I use Castrol Active 4T from supercheap cause I'm a tightarse. And I've got 10 weight fork oil in it (shell) just changing the fork oil makes a big difference and it's real easy to do
