  • larger tire?

    wondering what if any the pros and cons are for putting a larger tire on my fully stock 250 ninja + costs and recomendations?

  • #2
    Cons, worse handling.

    Pros, maybe more rubber selection in the 250 case...

      Why pay the extra $$$?

      Save the $$$$ for large capacity bike of which comes with a larger tyre as well.

        I went slight larger on my Rocket for nil cost and a slight improvement in fuel consumption. I increased the tyre diameter by about 24mm or 75.3mm in circumference and lifted the rear by 12mm.

          This^^^ Generally speaking a wider tyre will slow the handling and cause strange wear characteristics, different diameters can also have problems as well as possibly affecting the speedo readings :o

            ... and if the tyre is too wide for the rim you will end up with free range chicken strips.

              Check your clearances, might find the chain rubbing on your tyre.

                        You may end up with some weird handling characteristics with mismatched tyre sizes. Steering geometry on modern bikes is pretty close tolerance, and it doesn't take much to stuff it up.

                        Strongly recommend you get some expert advice from the Kawasaki people before changing tyre size, especially one tyre size only.

                          What do you mean by "mismatched tyre sizes"?
                          All bike tyres are essentially "mismatched".

                          It's on a 250. Chicken strips are par for the course.

                            No they are not.

                            Front and rear tyre sizes are different of course, but are matched in pairs to the bike's frame to suit the geometry.
                            If you raised the rear by say 20mm with a larger rear tyre, you would create an entirely different set of numbers in rake, trail and wheelbase.

                            Might not dramatically affect a little bike at street speeds, but I guarantee it would play havoc on the track when pushing the envelope.

                            Get expert advice if changing tyre sizes. All is not just looks.
