    Cool project! I am using Harley hubs front and rear on my CB750 tracker project. The great thing is that they are 52mm OD (at least in the rear haven't checked front I have the same front hub as you) and bearings are easily available that have a 25mm or 20mm axle size

    The weird thing is I am mounting the front hub up to an Aprilia Shiver 750 front end...what are the chances?:lol3

    You are correct about the front hub weighing a ton, I was shocked when I took it out of the box.

    Since you already have the front, it would be simple to get the rear Harley sportster hub. I do know those have a 52mm OD bore and a 6304 bearing gives you 20mm ID , 6205 is 25mm ID. And getting rims with 40 spokes is dead simple and inexpensive.

    Can't wait to see what you come up with.

    LOVE those Alitalia graphics on that bike on page 4.

    I also agree with whoever said they wish Ducati would make an adventure version of the Hypermotard. That would be nice but service intervals is still too high. My DREAM bike would be a Ducati Multistrada 1200 S Touring "adv" with laced wheels and a 19" front.....maybe 2 more inches of travel. That would be a new stock bike I would save up for and buy and risk a divorce over. :evil

    Answer/comments of my own:
    The rear should be back soon from Hagon, its a Metzeler Karoo (T), I think it might be the '2' version but it looks chunky and is every bit as good (and cheaper!) than TKC's.

    Front hub had to be bored on mine to take a metric bearing. The Dorso has 25mm axles, and I couldn't find a bearing with a Imperial OD and metric ID. I know there are 1" ID bearings but that is 25.4mm not 25.0mm. probably doesn't matter, but...
    The front wheel is super strong though, even if it is heavy. Its a steel rim, so that will never crack (or if it does I'll be in state that I won't worry about it...). The shape (profile) of the rim makes it less likely that there will be a puncture due to nipping the tube. 40 heavy duty spokes too. It is not going to break easily!
    My idea was to use Aprilia parts all the way through, as I do like the tubeless wheels, but as I said, finding a Caponord front that is not f%*ked is very tricky.

    I think you could modify a Hypermotard in the same way (off road wheels), its not that hard and I'm not an engineer - If I can do it anyone can! The biggest killer of things like the GS and 1200 Tenere for me is weight - the Dorso is just under 200kg's dry, which is nice and manageable.

    I got a 2nd hand front fender/fork protector and will cut that up to try to cover the holes.

    More pics to follow.

    Next part after the wheels will be that damn seat!

    I am going to bore out the front hub to take metric bearings, I think it was 45.7mm and I am going to 47mm. Rear is a bearing swap simple if you want the wheels to match front and rear.

    Not true! :deal the new Hyperstrada has a service interval for the valves of 18K miles.






    I also would like to see this but not in the 1200, my 820 Strada is plenty powerful slim light and nimble, add some laced wheels with a 19" front and adjustable suspension and we got it! :clap


    Hijack over please continue....

    Not until this year...
    I would never opt for an 820 if there is a 1200 available...I want it ALL, not 2/3's of what could be.
    I like the Multi WAY more than the Hyper...but that is what makes the world go round. If someone made "THE" bike and we all rode "THE" bike that would be boring.

    Probably a radiator guard. There are a number out there. I need to make sure the front wheel doesn't touch it too, as its pretty tight. The forks can go down in the clamps though and the rad can go back a bit.

    I got the rear on today, also put on new fork protectors that I made from an eBay 2nd hand stock part. They were just touching, so I trimmed them down with the angle grinder.

    All looks good but...

    Having had a Dorso, how do plan to address the tiny/small tank?

    I remember looking for a gas station at 100miles if I didn't keep out of the power.

    Build a new one, that's about the only option. I can't decide whether to use the standard silencer as a slave tank, and run a low exhaust, or just build a bigger main tank.
    Decisions...

    I recognize that recipe for fun! I have the same "cook book" on my shelf at home.:deal

    Nuthin like an overpowered SM setup for dirt sliding!
    Get those knobs spinning sideways and see how long they last...:clap

    My formula called for a couple extra CC's and some orange plastic, just add spokes.

    Well someone beat me to the knobbies on the DD. Maybe if I hurry I can still be the first in the US.

    Speaking of that, keep an eye on that oil filter. I found some pretty large dents in mine after a few hours off road, and I was on smoother tires. Those tires are going to throw some rocks. I have a homemade skid plate now, but for a while was using a rubber cap over the filter. If you can't find the right size, you could probably use rubber tool handle dip. A few coats should keep it from getting pierced.

    On the subject of the radiator guard, the most free flowing one I have seen is sold by Mike's Grilles in the UK. There are others, but they are generally restrictive to air flow, or have company logos on them. Second choice would be Palmer Products, also in the UK.

    Looking good, man!

    Did the ZX12R rotors bolt right up to the Harley hub? Inquiring minds want to know:D

    I was planning on using Hayabusa rotors clocked and drilling a new 5 hole bolt pattern.

    Yes that oil filter and the oil pressure sensor are very vulnerable to damage. And the front cylinder header too, for that matter. I am thinking of having the lower engine protection bars as the mount point for the skid plate. Watch this space.

    No, but they were very close. I had Derek Chittenden from Hijera Racing Developents fit them, he had to bore out the disc carriers standard holes and in the process move their PCD about 2mm larger. He then made inserts that fitted inside the carrier holes for the stock Harley bolts. The centre hole is almost right too, about 1mm larger than it needs to be.
    The discs would have fitted to the hub, but the PCD was just that little bit off.
    The discs also needed a 2mm spacer underneath each of them, to space them out to the required 134mm (outside edge of one disc to outside edge of the other).
    I will see if I can get some photos for you.
