    This is my 2012 Aprilia dorsoduro SMV750

    [​IMG]

    The idea is to build it into a ADV bike as good as any other multi-cylinder.
    This includes the following big things:
    - Wheels
    - Gas Tank
    - Skid plate.
    And there'll be a load more Other things.
    So - Wheels:

    I hadn't seen anything like this, before. So, just curious...


    17/17 or 19/17?

    This is the rear which is from a 2004 Aprilia (keep it in the family!) Caponord. It is 17X4.00 - 36 spoke tubeless.
    I bought the whole rear wheel sans disk (pics to follow) but was in pretty dire condition.
    I aim to run GS size tyres and TKC rubber.

    So here's the original Caponord wheel, pretty tatty:

    Here it gets a bath in WD40 in anticipation of deconstruction. Left overnight too.

    Here's another few pics of it before:

    Here are some pics after a bit of a clean-up:

    Sprocket is good, bearings appear to be ok. Hub was painted silver by Aprilia and thats a bit tired, but not too bad. I need to do some more work on it.

    Looking at the pics you can see I have removed the rim from the hub.
    Wow, that was fun. They were ALL seized - the problem is the spokes are straight, like nails, so as soon as you put the allen key on them, they just turn in the socket. Great!
    I had to clamp the spoke in a vice and then try. I managed to get all but one out, that one I had to cut the spoke.
    3 hours of my life I'll never get back...
    Anyway. The spokes are stainless, and are in pretty good shape, so I think I will reuse. The tensioners weren't:

    So In ADVrider spirit I made myself a tumbler:

    [​IMG]

    (old paint tin on the end of a cordless drill)

    Then added some crushed glass form the blaster (i would have blasted them, but they are too small):

    [​IMG]

    And let it run on slow until the battery runs out. I'll post the results later,

    Cleaned out all the holes in the rim with the cloth burr on the dremel:

    [​IMG]

    Now I just need to get the rim checked and I will start reassembly for alignment.

    Some concerns:

    Axles size - the 'HardBack' runs big axles, not sure what they are but I reckon either 25 or 30mm. The Capo is a 20mm.
    I can either replace the bearing (might be difficult, not much in the way of OD size) or have a new axle and spacer-inserts made up. I need to measure it properly and get onto SKF.
    The rear disk on the Capo is 280mm, the HardBack is 240. I think if I trim down a Capo disk it may work, but likely it'll need a spacer anyway. The spokes go left to right and vice versa, so there should be sufficient space for the caliper.
    I want to have a true bolt on bolt off with the standard wheels, no changing bracket or crap like that.

    Time will tell.

    Nice. :clap I thought about what you're doing when I saw pictures of this bike.

    What will you do about the extra space between the swing arm where the axle goes through and the new wheel assembly. It is going to look a bit awkward. I looked into a smaller wheel (150/80-17 adventure bike size) in the rear but decided I would have to cut and weld the swing arm assembly to get it much more narrow. Also the alignment for the sprocket to the output shaft will be off even if the swing arm were made narrower. Same problem up front but the triple clamp can be changed to a narrower assembly and front wheel. Do you intend to extend the suspension travel?

    I'm not overly fussed about looks, its more about how it rides. I will use longer spacers in the space, but the Capo hub is not as narrow as you may think. I will update with dimensions and specs later. If I were to try to address it, i would most likely build a tube steel custom swingarm - the design of the Hardback swingarm is really simple - it has no linkages. My biggest concern is how much offset I will need to use to ensure the centre line is maintained; I expect I will need to pull the rim over to the disk side a fair amount. The standard rim width is 6", the Capo is 4". This means that I might have to pull it over a bit.

    I think the front would be similar; it is not as wide. I guess we will see!
    I will take and post detailed pics for all.

    I plan to change the suspension as far as springs go up front (and oil). The rear will be a height adjustable Nitron shock.

    Nice project but it is such a beatiful bike... I would be really afraid to spoilt it...
    I'm going to follow the thread with interest :clap

    Have you considered getting Talon to make up some hubs to your spec?

    Interesting project. I've thought for quite a while (after riding one of those bikes a couple of years ago) that if Aprilia marketed an ADV version, I'd have bought it. I had to wait for the Tiger800XC to come out to find my ideal bike.

    Anyone tried running their DD hard for a while and then checking the MPG
    figures? I've spoken with someone who got 30MPG riding the bike in the
    dirt which makes for a lovely range.

    He swapped to a 990ADV and is happy with 34-38MPG in the same
    conditions. :huh

    The test bike I tried was averaging 43MPG which I figured was ok since no one
    was riding it slow..

    The tester I ran was in the mid 30s which would put me off somewhat since my Tiger get mid 50s. It was real fun though and, as you say, no-one runs a test bike slow.

    I was hoping it wasn't gonna be more thirsty then my Kawi 650R, but
    some real world riders shattered that dream (I was eyeballing the
    Shiver 750 actually).

    That engine sure is special, though, very quick to rev up.

    Hi - I did consider that option, but I spent all my moolah on the bike!
    I like the Capo hub as it has the cush-drive (I know Talon does these too) but it came with a useable 45T sprocket, good bearings and rubbers and that nice BEHR rim all for GBP50. Putting together a Talon/Excel combo would cost...?
    I think Aprilia are missing a trick here. ADV bikes are big and getting bigger world wide. In stock format the HardBack is nippy and it weighs a lot less than some other ADV bikes. Its compact and handles well. The Tiger is a great bike too, as is the 800GS, but the Aprilia was GBP6,600.

    Not tried to ride it too hard, it as 117 miles on it at the moment. The 12 liter tank is just plain stupid - probably only get about 100 miles on it if you are pressing on. I am aiming for double that, as anything less on an ADV bike is pointless.
