    Billy Lane huh? I wonder who really wrote it?

    Aluminum rims aren't much lighter, yes by mass aluminum is lighter than steel, but it takes more aluminum to match the strength of steel. So aluminum rims are thicker than comparable steel rims. There is weight savings, but much less than you'd imagine.

    The current tires are:
    R: 90/90-19 M/C
    F: 110/90-18 M/C

    If I'm wanting a bit more sidewall, would going to a 100/100 up front be too big of a jump? Would 100/90 be a safer bet?

    And as far as the type of tires (evidence of motonewbie in 3... 2... ) I'm thinking I like the vintage look. Something like the Dunlop K81

    What say the gurus?

    Thanks!

    I might be in the minority here, but I had K81s on many bikes back in the day and I like them. It's not as vintage-looking as the K70s that came on many of our twins when new, but far better for cornering than they are

    I think you've got your F and R transposed, no matter. I just looked into the feasibility of replacing a 90/90 with a 100/90 front on another thread and I even found a rim in my parts stash that had worn a 100/90,no issues.

    I might wonder about the 100/100 and fender clearance, if its tight you can slot your fender mounting holes a bit to raise the fender up.

    Cheers.

    Edit: have a look at this tire size calculator so you can make better comparisons based on tire sizes.

    Yep - had the R and F swapped.

    Thanks for checking that Alan! Slotting the fender is great idea too, if the tire's too close.

    Thanks for the link!

    Thanks Alan!

    For wheels, it seems all roads lead to Buchanan's -
    - Refurb a set of hubs, i.e. strip, clean, powder coat...
    - Send hubs to Buchanan's
    - They build new wheels with new rims, nipples and new spokes
    - $1,000 later, I've got new wheels... worth 50% of the bike

    I'd love to hear other options. Thanks!

    .. hit a local shop, see if they have a similar wheel / hub that can be disassembled. Take lots of pics, measurements, mark items accordingly. Disassemble, re-assemble, adjust runout and off set.. When ur done.. do it AGAIN, and AGAIN.
    When u feel comfortible, do your wheels... maybe you paint/powder coat ur rims, maybe replace them... maybe u get SS
    Spokes.. or strip and "coat" the existing ones..
    .. or take the easy route.. clean / ship ur hubs with a check and BOOM, ur done ...

    A friend of mine used to own a high end bicycle shop, when I asked questions on lacing / truing rims. He said he wins both ways... even if people do it themselves, why? Because they always get brought to him to be FIXED.
    Like the old sign in a mechanics shop..
    3 prices
    Flat rate if WE do the work.
    Double rate if u watch and ask while we do the work
    Triple rate if we have to fix what you EFFED up while trying to do the work yourself ..

    That's exactly why I learned to build wheels myself. If shipping them wasn't prohibitively expensive I'd offer the service to you.

    Have you checked out MikeXS rims? Many here on the forum run them and have had great success. They have different options for shouldered, etc. They also sell stainless spokes for much less than Buchanan’s, but after speaking with them they said they could not guarantee fit with Honda hubs. Buchanan’s spokes are made to be an exact fit for the stock Honda hubs. One set of stainless spokes will cost you though! But, you’ll never have to worry about rust and they add to the bling factor. I plan on buying a set in the near future.
