    A few years back when Rosie got her WR250R I rode that & thought a 450 version would be the ducks nuts. 60000km later I've spent more time working on that fucking Yamaha than I have on my bike during 155000 km of KTM ownership & I'm not so sure...

    Cheers

    The blurb on the Honda Oz site says it has a crush drive.

    the precise words used in the article were: :deal

    rubber-damped steel sprockets


    So... no - NOT a cush drive rear hub.

    FWIW... I think that the "rubber damped steel sprocket" is an attempt more in line with reducing the bikes overall noise level (chain slap), more than an attempt to provide less strain/transmission longevity of the gearbox (as a cush drive rear hub would).

    In the article on the CRF450L advpulse.com/adv-bikes/2019-honda-crf450l-announced/ they make a big old song and dance about the efforts HONDA made to keep noise level down, were foremost in the design brief. :deal

    A major factor in getting a bike to be street-legal is passing noise regulations. One part of that test is a drive by sound measurement where the overall sound of the bike, not just the exhaust, is recorded. Rather than just focusing on the noise coming out of the muffler, Honda found other ways to keep the overall decibel level down on the CRF450L. Engine case covers are on the right and left sides of the engine. Not only are these for protection, they dampen overall engine noise. Also, there is a full cover over the front sprocket. Again, more protection but sound damping as well. Even the swing arm plays a noise reducing role. It is injected with urethane to lower the overall bike volume. Lastly the exhaust system is a dedicated street legal unit to keep noise levels down.

    and all of that is what helps contribute to the "porkiness": :deal

    https://ultimatemotorcycling.com/2018/05/23/2019-honda-crf450l-fast-facts-and-photos/

    To go from an off-road bike to a street-legal motorcycle did require a number of changes. The 2019 Honda CRF450L gets different ECU settings for cleaner running, a more restrictive airbox to quiet things down, various emissions-controlling doo-dads, a fan for the thermostat-controlled high-capacity radiators, a more powerful AC generator for the streetable LED lighting, a stronger lithium-ion battery, rubber-damped steel sprockets, thicker case covers to deaden noise, a dedicated box for electronics, mirrors, switchgear, DOT-legal IRC rubber, and oddly enough, urethane injected into the swingarm to make it quieter. All that adds just 14 pounds to the CRF450L—amazing.

    14 Pounds = 6.35 kg's.

    How much do you reckon the bismark muffler weighs over and above that...?

    Getting eight to ten kilograms off the CRF450L's showroom tag weight seems achievable enough...?

    And I quote, "and a crush drive has been added to the 18-inch Enduro spec rear wheel."

    I'm not too fussed if this is incorrect or a different interpretations of what a crush drive is as I don't think this bike is my unicorn, but it sure would be interesting if it did come stock with a crush drive.

    It's a little disappointing to see that at least one manufacturer has made at least a passably interesting attempt at the bike we ALL bleat about and so many people promptly jump down their throats for doing so......

    At first glance, I can see the BASIS for a GREAT bike here, I'm going to keep a close eye on this, I'm intrigued.

    I'm on a phone. I'll blame the autocorrect.

    Crush . Yep. Autocorrect.

    And having had a look at a pic of the rear wheel, it doesn't have a cush drive. An official website appears to be wrong.

    Huh? No they haven’t!

    “passably interesting attempt” Don’t attempt it....do it! Over weight, underfueled, under powered. Did someone mention 26hp? FFS. There’s nothing here to make someone choose this over any of the enduro offerings from Europe.

    Why?
    No mate my point is just beacuse some enjoy an enduro weapon with a big tank, doesn't mean it's the only way to do it.
    Obviously the Graham Jarvis-esque portion of this forum would need more to satisfy their skill sets but I reckon your gonna find a few of these chugging around in your high country with all kinds of pilots aboard weather you tear it down or not.

    Pretty keen to see the trend evolve and maybe then the bar can continue to be moved for people with greater needs?

    Is it 32K servicing intervals or a full rebuild at 32K, if it’s a full rebuild I’ve lost interest.:hmmmmm

    Several thousand adv posts ago in several threads bemoaned the demise of the XR650R and there was countless spears aimed at Honda about...."er well ifn they only woulderer put an electric leg on the BRP "they" would sell shit loads of 'em." So maybe Honda was listening to youse lot after all and this is what ya get... lighter than a 650 too. Looks promising to me. Good onya Honda

    Firstly, I would challenge the 20 odd hp rating being bandied about here...gotta be more like 40 odd.
    Pity about the cush drive hub not being a cush drive hub :imaposer

    The fork coatings are suspect...that gold anodising looks very similar to the Africa Twin's. Other manufacturers have complained about Showa quality as well

    Gotta say, the only thing better than the older CRF450x seems to be the 6 speed gearbox as although it has a longer lasting piston design, I think the old Ti valve issue is going to play with it's reliability. Get that sorted and it's going to be a great weekend warrior bike that can be ridden great distance between home and forest (fuel allowing)

    Plenty of larger tanks getting around for the R and X...shouldn't be long before one is available for this model as well.
