    Hi guys!
    I have finally got my new CRF 250L. Currently I've ridden first 600km offroad/road and I am starting to pull some higher rpms. Around 6000/7000 the whole bike starts to shake that its really uncorfotable to ride in the seat. Is this normal? Is it gonna get better with more millage?
    Sorry for a beginners question :)

    Have a great day and thanks for your help!

    Revved to 6,000-7,000? Is that our question?
    How fast are you riding? Or is this revving it up for offroad riding?
    It's a single-cylinder, so I'm guessing you won't be spending much time at that RPM range before noticing some serious noises. :)

    Exactly, at approx 6000 RPM the vibration starts and continue. Its the same at any gear.
    The noise I don't really care but its not comfortable to ride on, even almost impossible to sit :)
    I hope its because the bike has only 600km so it will settle down

    I guess my comment was a bit too subtle. I don't think the bike was intended to be ridden at those RPMs for anything other than climbing a hill in low gear for short periods of time.
    Probably a good idea to shift up to the next gear. It will comfortably do highway riding up to 60-70mph then you've got very little left.

    It is actually getting a bit better, at 120 the vibration is still a lot but lets see with more millage. I have now approx 1000km.
    Thanks a lot for your reply anyway :)

    It does calm down as it breaks in. Don't listen to superfunkomatic. This engine can sit at 7000+ RPM all day long. It came out of a street bike with similar gearing and at highway speed the cbr250r is at 6000-8000 rpm. Mine does not vibe at those rpm's, so it might be a good idea to check your tires and wheel balance if it doesn't calm down after 2-3000 kms.

    If you're riding it at 7000+ all day you're on the wrong bike. You'll get nowhere near those RPMs even at 120 km/h.
    Even at 120+ there is very little vibration in the motor with the counterbalancer that Honda has fitted. If you're getting 'vibration' something is wrong. It's a pretty buttery-smooth bike for a single cylinder, unlike the KLR I had which was like sitting on a paint shaker. :)

    Here's someone's top speed video on YouTube. It'll run well past 7000 RPM. Wouldn't want to ride it like that all day.

    120 km/h is ~7500 RPM on a stock CRF250L in top gear. Just FYI. That's close to top speed (due to power/wind resistance) on a stock bike, but that's another subject entirely ;)

    Thanks a lot guys, I was mostly looking for any similar problems. If you guys saying it should be smooth I'll wait for 3k and if it doesn't stop I'll start to investigate..
    Anyway, Thanks a lot for your inputs.

    Be safe
