    ZX25R small inline 4's again? !!

    Rumors, rumors, awesome rumors



    "Japanese magazine Young Machine reveals the plans for a new Kawasaki Ninja ZX-25R. According to this Japanese publication, the Akashi factory has already developed a new engine. The frame and the rest of chassis components are the next elements to be developed. The Ninja ZX-25R hopes to bring back the sport performance of the small displacement sportbikes of the ?90s."

    Saw this online earlier, looks promising. Rotors are pretty small.

    Concur. I nearly bought a CBR400 a few years ago, banana swing arm stylee.

    It was hilarious, couldn't keep my eyes off the silly numbers on the rev counter.

    Unfortunately I'm 6'2" and it was a tad cramped, it also encouraged warp speed corner entry and silly lean angles. Shrieked like a demon with it's nuts caught in a belender. Addictive - the noise.

    I wonder what kind of performance to expect with 20 years or so of development? Exciting.

    Would they compare to an old 2t twin, TZR, KR1, RG ?

    if it has good suspension this would cost pretty much the same to make as a zx6r, which is currently around 18k,

    even if they got it down a bit, to say 15k,

    would you pay 15k for a 250?

    there is a reason the original 4 cylinder 250's never got sold new outside japan, other markets would not pay the money for them,

    nahhh think more like 8K like the current 3-400cc's --- suzuki's is oil cooled SACS revision -- most likley engine built in japan, bike assembled in Thailand/Philippians like the current 400/650's etc etc

    After reading the magazine blurb and some blog entries this is just a rumour that the magazine claim came from a source in Kawasaki Indonesia. It originated because 3 years somebody took spy photos of a white ninja 250 that they thought was a 4 but it was actually just a normal twin. Young Machine ran this exact same story a year ago saying Kawasaki might show it at the Tokyo Auto Show. They didn't. Now they're saying they might show the engine at the TAS this year or maybe next year.

    And fwiw the guy who wrote the article linked in this thread should turn in his keyboard to the authorities for actually writing in real life that it would have 60hp. Needs to lay off the booze before writing at the very least.

    Sooooo, we can get singles that rev to 13,000+rpm. How fucking much could that sing to?

    Better yet, run it cross plane and get a bit of extra torque so it doesn't need to rev quite as high.

    The old ones were 19000. Hopefully this one is up there somewhere.
