BUMP!
Ooooh - Henry Abe wheels with an 18" rear drum? Makes me wanna go watch MAD MAX 2 THE ROAD WARRIOR all over again! Think I will.....
Seriously though, a set of these wheels really would best be used, should be used, on an early ZED, turbo, with Vetter quicksilver fairing etc - as a "WEZ" replica bike!
How cool would it be, to really get the thing right, nut & bolt using good hi-res pics for a template rather than a fuzzy old black & white TV like so many earlier replicas must've been done from - AND to get the TURBO working right?
Seriously - I'd rather keep 'em on the shelf awaiting THAT possibility, rather than sully a decent SOHC-4 with a too-heavy pair of cast-mag wheels!
Just grab some good light weight Akront rims, lace 'em to the OEM hubs - do the dual 296mm front end upgrade, maybe grab some COMSTAR wheels if you wanted to get all progressive & race-replica with the thing, do it up like a proper late-'70s Honda four-cylinder racing FLAGSHIP - as an RCB replica, in miniature. Plenty of far far better things to do with the BIKE is what all I'm getting at.
But yeah, shouldn't be too much trouble retro-fitting a Kawa front rotor & speedo-drive, shoe-plate on the rear - Would even be feasible to use the Kawa's six-lug cush-drive with the Honda four-lug style wheel - would be well worth doing ANYTHING of that nature, just to dig up an 18" rear drum hub ABE wheel, and mate it to the early ZED TURBO - What fun it would be, to butcher the hell out of that VETTER fairing, too.....
One of the few things which would tempt me into ZED land, actually! Other than the kid's "KZ440LOL" which should've been replaced with a SOHC-4 when it burned to the ground - NOS belt-drive or not, the pulley could've been machined to suit the CB450 DOHC-twin, or a CB350F etc etc - Would be well worth running skinny OEM width rims just to see that fat KZ belt running on a smaller earlier DOHC-4 Honda like a CB750KZ-LTD for instance...... Anything really, just to keep it within the same Honda 'F-amily as so many other bikes I've owned & loved!
So too with the cast/mag wheels - this pair right here, the WEZ REPLICA thing? Just about the only reason on this Earth why I'd want a pair of cast wheels! For a replica, fine - for PRACTICAL purposes, gimme a pair of Comstar wheels, or a wire-spoke alloy rimmed wheel-set!
I realize they were made & sold for the SOHC-4 series, I get it - they're period-correct & everything. But do we have to accept everything the period-Aftermarket offered up? Even the truly bad ideas, like 7-spoke Cast wheels? These are some of the nicer looking examples, don't get me wrong - but they're still sheer & utter nonsense from a performance perspective!
Well - AIN'T they?
Surely they were lighter in the hub area. But whatever mass was conserved inboard, probably more than half of that was moved OUTBOARD - measure the wall thicknesses of wheels of these types, compare 'em to an extruded hoop-bent butt-welded alloy WIRE rim? No comparison - even with steel spoke-nipples, that wire rim's gonna weigh less than the enormous hunk of alloy WAGON-WHEEL's perimeter.
Gonna NEED a 900cc Turbo to push all of that dead weight around.
Or am I MISTAKEN? If anybody's got a set of these, sitting bare without tires, WEIGH the bastids!
Meanwhile, anybody building a set using OEM hubs, sensible lightweight spokes - ideally with coated brass nipples for a true lightweight build - using alloy rims with bead-retention ridges - seal 'em up with Silicone to reflect a MODERN interpretation of "period-correct" which is to say if it's out of sight it's out of mind - kinda like an electronic ignition or some ceramic coatings around the combustion chamber - weigh up THAT pair of wheels.
We should have some proper NUMBERS on this stuff!
Not to obviate the use of 7-spoke cast wheels altogether, but rather - to clarify just when we're doing something for fashion - (Nothing wrong with that, aesethetics are the only reason LEFT to own a Classic in the first place!) I'd just hate to see the new young enthusiasts be taken in by the same advertising from period magazines, as what hooked the FIRST generation of SOHC-4 aficionados - let's judge all of this old stuff on it's MERITS!
I'd love to see something similar done with the brake-rotors, also. Being that the rotor shown above is indeed "over-drilled" having less mass yes but also less surface-area at the same time - It would be nice to break down all of the period braking MODS, including the caliper swaps I suppose - but mostly the rotor drilling versus rotor SKIMMING - If there were some sort of brake testing rig simply mounting rotors on an electric motor & spin 'em up, slow 'em back down again, and measure their temperature & distribution using thermal imaging etc -
I mean, yeah I suppose again there's a certain FASHION - there's an "ideal" ratio of cross-drilling which is in part derived from theory but also at the same FASHION or at least AESTHETICS - But if there's some way of doing the discs BETTER, especially if it boils down to spending the same $$$'s more or less - namely the skimming or replacement outer discs etc - people considering upgrades to these bikes should be given the best possible info, rather than FASHION advice!
I know, I myself I'm quite guilty of it - I'm always ranting about what visions are swimming in my head of "perfect versions" of this or that model. The "hand-me-down" scheme wherein I'm so utterly fixated on upgrading forks & brakes to that of the next-size-up model of bikes, & in the meantime swap out rims for matching diameter pairs in as wide a profile that was available at the time, sometimes suggesting stuff which was FEASIBLE using period-correct components, but surely probably never actually DONE, for one reason or another - probably the absence of decent TIRES for 'em.....
But yeah - either way, it'd be nice to know just how much all of these aftermarket 7-spoke wheels actually WEIGH! And stock steel-rimmed wheel-weights for starters, as the baseline. And while I'm sure it could be calculated based on displacement of water valume versus measuring thickness at certain points across it's width, down the spokes etc - to determine density of the casting alloy, as opposed to the cold-worked (aka cold-"forged") extruded profiles of the wire rims - Surely however, at a certain difference in thickness there's no drawing equivalencies any longer as the profiles couldn't be THAT dense the castings couldn't be THAT porous!
