    I'm going to buy a new bike and am tossing up between the cr250 and the
    crf450. I recently sold my 98 cr250, and have always been a fan of the
    simplicity of the 2-stroke engine, I realize the technology that has been
    put into the new high revving 4-stroke bikes but also think the motors must
    be on the edge, sacrificing reliability for power. I am aware of the
    teething problems that came with the first model of the yzf426 and am
    worried about any problems with the Honda. I trust Honda doesn't have so
    many problems, being such a reliable maker of bikes in the past, but I need
    the perspective of unbiased opinions. any opinions are appreciated, also
    about the differences in power delivery and handling. thanks

    well first of all you need to decide where you are going to ride this will play a part on
    which bike you would buy

    the Honda is a first run
    the Yamaha has been through 400,426,now 450 , this would prob be a consideration

    the 4 strokes are reliable now with good power delivery , good oil often and minor other maintenance and all good

    You cant go wrong with the CRF450, its in its second year now, but even
    the first years didnt have any trouble. Well the one that was raced
    here didnt anyway (lots of pony express races and enduros). I
    personally wouldnt go for the YZ426F as I read reports (never ridden
    one) that the power delivery is somewhat two stroke like in order for
    Yamaha to tempt two stroke riders over to the dark side. The YZ450F
    glows in the reviews I've read, 4 speed box = mega torque. Chad Reed
    went for a blast on it and was only using 2nd and 4th gears!

    Dont discount the YZ250F though, I personally saw one beat the guy on
    the CRF450 last year (both very, very good riders though). I have
    ridden one of these (YZ250F) and found the power delivery to be great,
    you can just open the throttle in the turn without worrying about
    wheelspin and it just hooks up and drives out. Whereas on a two stroke
    (especially my old IT250) throttle control is critical. The YZ250F is
    deceptive, it feels quite slow because its not hanging the back out like
    a stroker, but instead its putting the power down and driving you out of
    a turn. And it bloody revs till only dogs can hear it! Also, the
    CRF250 will be here soon.

    You know, Ash, when BT had the rally in his paddock, had I come, I would've
    quite likely left the 6R at home and come in the van, YZ-F in the back, so
    as to provide some slapstick... would've been funny to watch a succession of
    people pipe up, "Oh, give_us_a go", stumble over to the bike, try to kick it
    while still holding their stubby of VB or bottle of poofta drink in one
    hand, lose their balance and get pinned to the ground when the bike falls on
    top of them... bonus points if the kick which sends them toppling actually
    gets the bike to fire and they end up having the header pipe singe the hair
    off their right calf.

    I regret my not doing that even more now that I realise that, had I done it,
    you'd've had a go, and you'd've had this preconception you have about a
    YZ426's vicious power delivery exorcised from your skull forever.

    As it stands, you'll now have to wait until I fix the clutch cover... @#$%&!
    Yamaha, stick a flimsy-arse bit of cast magnesium right where the rear brake
    pedal can smack it... @#$%&!

    For the record, the one time I rode a CR-F, I found it considerably harder
    to ride than my thing. The YZ-F growls off the bottom end, then builds. The
    CR-F just comes on in a surge, like a two-stroke, except it does it right
    off a closed throttle, instead of a third of the way around.

    Fairy 'nuff, like I said, I've never ridden one, thats just what I've
    heard. Mind you, I should have known better really, its obviously like
    the "two strokes are unreliable" stories. At least I had the disclaimer
    that I've never ridden a YZ426F :) Actually maybe it was the YZ400F
    the stories are about. Hmmmm, bottom line, **** the stories, ride as
    many of em as you can, base the decision on that.

    As for a ride on your YZ-F, tempting, but I dunno about that
    decompression lever and all that hot start button malarky, I'm a fan of
    the electric leg myself. Though having said that, I havent seen many
    people struggle to start their YZ-Fs'. The XT doesnt have enough
    compression to warrant replacing the broken automatic decompression cable!

    One point about the CRF is that the decompression lever is on the
    handlebar next to the clutch lever, which, I was told by one chappie,
    made it nigh on impossible to start in gear as he had trouble holding
    the clutch and decomp in together. 'Course the solution there is not to
    crash, but he was a fellow C grader and much faster than me, so I wont
    cast any stones...

  6. Chad Reed went for a blast on it and was only using 2nd and 4th gears!
    Fairly hard not to use 1st to get going and 3rd between..

  7. ****, this is Chad Reed we're talking about... if he'd_really_wanted to show
    off, he'd've done the whole course in neutral...

    Ride any bike less than your own is usually harder.. The CR-F owner
    would say the same about yours.

    Good point, but I meant once he was rolling as you damn well knew :)
    You can skip 3rd if you just click up twice without letting the clutch
    out, either way, gobs of torque. Besides, I probably got the story
    completely wrong, I think I read it while browsing the mags in a
    newsagents, didnt buy the mag.

    True, now I think about it, I've done a few starts in second to reduce

  13. Different story on a 4 speed bike. Specially if you have your gearing
    right for the track
