    Unhappy Gixxer 250 SF- Knocking sound on accelaration

    I have bought a new Gixxer 250 SF. After every gear change, when I try to accelerate, it makes a knocking sound (not like regular revving sound).
    Is it normal ?

    Are you short shifting aggressively?

    Gearing on every bike is different if you are shifting according to what you used to do with your previous bike ( assuming you had a previous bike) then you might get the knocking sound. You will take some time to adapt to the shifting points in this bike. I hope that's the only reason for the knocking sound of the engine.

    Knocking (engine) generally arises ,if the gear is not engaged at right RPMs. Try shifting the gears above 4K RPM and check if this problem exists !!!

    i agree there is a little sound as i too own Gixxer SF 250, but this is due to improper gear shifting according to RPM. There is no knocking if gear is shifted above 4 to 4.5K RPM. But the bike lacks yamaha smoothness. There are vibrations and quite noticeable at certain RPMs. I am too looking for an ownership thread.

    Congrats on the new ride bro.
    I don't think there is an ownership thread for gixxer 250 yet.
    why don't you go ahead and start a thread of your own and share your experiences.
    We would love to know about you and your new ride.
    Don't forget to add lots of pics.

    As for the knocking sound; yup it is due to short shifting, always shift at above 4k RPM. These bikes are not to be driven like a splendor, where you reach 4th gear at 25 kmph and go along. They like being revved and the engines like producing their power at high rpms. Short shifting will be harmful in the long run. keep it in above 3k rpm even if you are riding lazily and shift after 4k rpm.

    Ride safe bro and congrats on the new bike again.
    I would like to thank my legs for supporting me, my arms for being always by my side and my fingers; I could always count on them.
