17" spoked rear rim?

[Gearhead 63]

I like almost everything about the early CB750 K models except for the ultra-skinny rear wheel and tire. I'm thinking that replacing the stock 18"x2.15" rear rim with a 17"x3" (or possibly a 17"x3.15"?) and using a 5.00"-5.10" width tire would be just about perfect for my bike (and fit without having to remove/modify the chain guard?).

I've been searching all over the internet trying to find a chrome 17"x3" 40-spoke rim that I can lace up to the stock hub. Haven't had a bit of luck. Can only find the Harley-style 16"x3" rims.

Anyone have a source for a 17"x3" chrome 40-spoke rim?

17" 40 spoke will probally be hard to find, Might be one out there somewhere. I laced up a 16"

Found a good deal on a new-in-box 16"x3" 40-spoke drop center Harley rim earlier this evening. Couldn't pass it up!

So.... exactly what spokes will I need to lace that rim up to the stock '73 CB750 rear hub? [And a source on where to get the spokes, if possible!]

Looked at your gallery pictures (dan1951) --- looks like you've got a Dunlop on the 16" wheel (maybe a K591??). What size tire --- a 130/90-16?

I got them as a kit from Buchanans.com there not cheap from them like $120 on up. Depends on what You want You probally can get them cheaper else where but there well made. Yes it,s a 16" dunlop I will have to get back with You I forgot the exact size.

Thanks! Please do let me about the tire. Looks like the setup I had in mind.

Yes it,a 130/90/16 it gives You approx. 1" clearance from the swingarm. You might want to go with the Dunlop K591 the D404 I have has developed side wall cracks after 5Yr,s glad I checked it this morning could also be from neglect of correct tire pressure.

 

[Gearhead 63]

OK... a Dunlop K591 it will be! Just need to get the correct set of spokes and inner tube --- then I'll be "in business".

Don,t forget the rubber rim liner for that 16" rim.

Forgot to list that, didn't I? I'll make sure I've got one on there. Thanks again.

I have a set of Bridgestone Spitfire (raised white letters) on mine. 130/90/16 and 100/90/19.

I got lucky and found a set of chrome spokes on Ebay. The rear rim already had miles on it when I got the bike but several spokes were broken and several more broke when I had it trued.

I wound up ordering a Bridgestone Spitfire S11 rear tire (without the raised white letters) 130/90H-16. Just couldn't find a really good price on the Dunlop K591.

Buchanan's Spoke & Rim had the correct spoke and nipple kit listed on their website. I ordered it, but haven't heard anything back on the order as of today.

[Later today] Correction! Payment has been made to Buchanan's Spoke & Rim and the kit has been shipped!!

Now I have a LOT of work to do on the 750. Have spent/invested approximately $3000 in new parts and tools. Will keep and store ALL of the original Honda parts so I can put the bike back to original "on down the road". I'm thinking that I'll enjoy it for the next few years (set up the way I want it) and then return it to the original configuration in 2023 --- when she's 50 year old.
