Tapered head bearing info

Top bearingBottom bearingnote
Timken part number This bearing looks like a Timken 32005, and in fact some aftermarket replacements say that on them, but it isn't.  It's a modified one with a 26mm I.D., rather than the 25mm of a 32005. 

Nachi (and others) make a 32005 with a 26mm ID. Their part number is E32005JS/26. Search for “32005/26” or “32005-26” for many options.
32006 This part number is a generic metric bearing number, and any bearing shop should either have it or be able to get it quickly.  I quote Timken because the local shop said it was the best bearing manufacturer out there.  Even if he's just spouting, they're still a good brand and this price is much cheaper than the part from Honda.
O.D.47 mm55 mmThis data is probably useless, the part numbers above should describe a unique bearing.
I.D.26 mm30 mm
height (measured)15.6 mm17.9 mm

These don't include the dust seals.  Stock dust seals cost about about $4 and $8.30 for the top and bottom respectively if you buy them on-line.

There are tapered head bearing kits available that include both dust seals. That's probably the path of least resistence.

brand part number notes
All Balls 22-1020
Parts Plus SSH-903R
Slinky Glide AH-3577 wemoto part number

Honda used the same combination of bearings and dust seals for something like 80 models over 40 years.
Here is a cross reference.

Front wheel bearing

The left and right wheel bearings are identical.
NSK part number6004(v)The "v" is the seal type.  There are several types.  "v" is the non-contact type, which will last longer, but not be completely waterproof.  The contact type (I don't rememeber the suffux) is more waterproof initially, but doesn't last as long.
You should be able to get these bearings at any bearing shop.
I.D.20 mm
O.D.42 mm
height12 mm
Priceabout $12 each.

Front brake rotor

Mike Dean says, "... a stock VFR Rotor from the early 90's should be the same part, other than a style difference."

The Hawk's front brake rotor is 316mm in diameter

EBC's fitment chart suggests that the following rotors are usable: I have not checked this! -Webmaster

What's intereseting is that EBC lists the FA226HH for the front of the CBR600 F3,
but all the other vendors say the F3 and hawk use the same front pads.  If it were
me, I'd get the FA142HH pads if they were available, the FA226HH if that's what's
in stock.

Cheap ass fork seal driver

You can use a schedule-40 PVC coupling for 1-1/4" PVC pipe as a fork seal driver.  They can be had at Home Despot for about $0.45, the only modification you have to do is to grind/file the ridge in the middle away.  Cheap and easy.

Male and Female Shutoff Valve, Part No. 245-1495 from: Lockhart Phillips, $21.50 each

You need the 5/16" valve for the Hawk.  Female shutoff (#245-1493, $16.95) works fine for me.  BTW, these valves may be found at most good bike shops.

Soichiro Honda's birthday

November 17th 1906

Japanese industrialist Soichiro Honda, born in Iwata-Gun, Japan (1906).  He ran several small manufacturing operations before and during World War II.  After the war, he had great success manufacturing a small gasoline engine that could be attached to a bicycle to transform it into a motorcycle.  He began the Honda Motor Company, producing first motorcycles and then small sports cars.
