    (Not so) good vibrations!

    I've had my CR 2 months today and have put £2k miles on it now and some vibes are really bugging me - I mentioned this in another post but thought I'd give it a while and try and diagnose it a bit.

    What I'm observing is this. It's definitely Engine vibes as when I pull the clutch in and back off the throttle whilst at speed it goes away - so it's not chain or tyres etc.

    All is lovely and smooth below 4000rpm, as soon as I go above that it starts vibing, it's not a small band though that you pass through it just gets more vibey. What this translates to is that when cruising along in 6th gear its fine up to precisely 4k - 62mph. Then the vibes kick in at which point the bars, the pegs and even the tank can be detected vibrating. It's not enough to cause numbness of hands or feet, but its distracting and makes the engine not feel smooth above 4k even though there is nothing wrong with power delivery. Above 80mph circa 5k rpm its enough to make my eyes affected very slightly.

    If I really give the bike the beans through the gears I can feel the vibrations very strongly which is moderately distracting.

    Is there anything I should be checking - or can get checked because to me it just feels like the bike isn't quite behaving. OR do any of you other members see the same behaviour?

    Outside of this behaviour the bike is really lovely but this is mostly ruining it for me.

    What do you think?

    M8, that does not sound right but the only way to be sure, I think, is to get someone with plenty of Crossrunner riding experience to ride your bike (and you ride theirs) to compare them.

    Hi Skids,

    That's sort of what I was thinking too. It's not shockingly awful, but it doesn't feel right. I've had numerous other bikes in the past so I do understand that to a point vibes are part and parcel of biking but usually the run in bands.

    I was originally hoping it would be something simple. I did talk to The local Honda dealer but they were of the opinion that sometimes you just get a vibey bike - which obviously isn't that helpful.

    That sounds like a typical crap-dealer get out of jail free excuse.  :112:

    I had a similar issue when I got mine, it was at faster speeds but if I had false teeth they would have been out. ,mine was secondhand, don't know your nee or not, but previous owner had anti puncture gunk in the front tyre, nee tyre, problem gone. If you have a secondhand bike & it perhaps has been sitting a while with said gunk in tyre, then that could well be same thing, worth checking anyway

    Hi Willie,

    Thanks for the thought - in my case though its definitely engineer related as they dissappear when the clutch is pulled in. Something with the tyres would remain clutch in or out.

    Does anyone know of any common valve issues that may cause vibes etc?

    There are no common issues causing VFR's to vibrate that I am aware of and I've been around and ridden them for over 20 years.

    Worth an ask on VFRD?

    No other VFR-riders in Essex to compare bikes?
    Stop making sense

    None that have come out of the wood work yet!

    I have about a month left of warranty from purchase of the bike, so really need to get it looked at if you guys think the bikes are mostly not full of high frequency vibes.

    I think this is the way forward.. get someone familiar with the bike to ride yours, and you ride theirs. I'd gladly offer, but am a bit too far away from your part of the world.
