Topic: 16 inch rim on rear question.

[ekim98]

I should warn ya its a heavy boat anchor of a wheel.

You got that right, about it being heavy, both the rim and the amount of rubber to make that big tire. I never would have put it on, it was there when I got the bike. My biggest problem is the squarish  (is that a word) tire thread. Great for drag race traction but not for corners it's to much like a car tire. After I get the engine fixed I'll probably get the Bridgestone Spitfire to replace that Chen Sheng or what ever it's called.

Loud, Fast, & Ugly has the whole kit for $129, for those interested in the 16" rim and wondering where to find them:

"You get:

* Harley-style 40-hole drop-center chrome rim
* spokes set for '69-78 CB750 SOHC (also fits CB450 twins, CB500-550 fours)
* tube (16" side valve, metal stem)
* rim strip,

All for $129 (plus shipping)

rim only $69
w/ tube & rim strip $79
spoke set only $59"




I have seen the parts all individually on eBay cheaper, from time to time, but in case you are impatient or just want it all in one fell swoop, there ya go!

A common set-up on the SOHC4 bikes is a 16" x 3.5" (40 spoke) Harley rear rim - anything wider with a stock swingarm will probably be an issue clearance wise. I'm running that same rim with a 140 tire on my CB500 with no clearance issues other than moving the brake arm outboard. Cycle X sells offset sprockets, mainly for use on rigid chopper setups.



For ease I'd go with the stardard HD size that I listed above. If you've got plenty off cash, skills, and money - you can do whatever your heart desires.

Is that back tire a Pirelli MT66, 16"?  If so, where did you get it? I am running one on the front but was having trouble finding one for the back, in 16"

Just thought I would also add, that there is a store on eBay that frequently lists stainless steel spoke kits for the Honda hub to Harley rim conversion. Also, he just listed another set - he seems to list them about one set a week.

Moto-Bunny - that rear is a 140/90-16 and I got in from Dennis Kirk if I remember correctly (been over a year). Can't say for sure if they'll have the size you need.

I agree with Moto-Bunny on the parts being available cheaper individually on eBay. I got my spoke set for $25 shipped (brand new stainless), my rim for $50 shipped (brand new also) - of course you know a tube & rim strip can be had for well under $20.

I have a 16" rear on mine (76 cb750f) and yes, it does handle something like crap, or an old cruiser with clubmans that can lean over a lot.

 I have only had the bike running for 2 days and it looks like I have almost gone past of the edge of the rear rubber! I live in SF city and cant lean over as much as I would like to. I also noticed that it doesn't want to hold a line, you have to push on that inside grip pretty hard and use your weight to steer to keep your apex tight.  I guess I'll learn to hang off more than I do already to keep my tires from seeing two yellow lines every corner exit I guess I could slow down but that isn't much fun is it.

Does anyone know of a sporty 16" rear that has more of a pointy profile?  I'm running out of rear tire faster than my learning curve on this new bike. I'm guessing that when the "feelers" finally touch down I would then be crashing, or trying to imitate Hailwood.

Thanks for all the info - especially where to get that Pirelli tire (it IS a MT66, by the way - what I am running up front already and seems to be a really good tire (especially in the wet which (looking outside right now. . . *sigh*) happens all too frequently here in rainy Orygun   

Also, its nice already knowing the max rear rim & tire size I can fit on my CB500 without having to figure it all out via trial and error - thanks for having already done all that for me!
