That's a CB750A Hondamatic, with the two-speed automatic transmission & fluid-filled torque-converter. 1977 or 1978 vintage. The bars may or may not be original, but they look overly tall IMHO. Plus, if you look at the fitment of the front fender to the tire's edge, it looks like it might have a non-stock 18" front wheel in place of the 19" stock size. Which makes me question the validity of it being a '78-'79 version, 'cause the rim might have been added after the fact, to an earlier vintage bike so as to "modernize" it, at some point early it it's life. It's also a pretty damn cool mod, IMHO - I loves me some Comstar wheels, and I can especially especially dig an 18" front rim on a Honda CB-four be it SOHC OR DOHC (CB750/CB900/CB1000/CB1100 etc) - What's also unusual, is how this is the only model which had the early type 9-rivet 296mm single front brake rotor, WITH the Comstar wheel - Meaning this rotor has the five bolt holes as opposed to six bolts - Meaning these same CB750A rotors can be used as a cool mod of their own, replacing the later "vented" type 296mm rotors, the double thick automotive type discs, from the "pro-link" '81-'82 CBX, the GL1100A Aspencade, or most notably on the '82-'83 CB1100R homologated endurance racers. Well, that is IF you'd want a middle-weight option for the 296mm rotors on Comstar wheels. 'Cause the '81-only CB1100RB "dished" type 5-spoke/10-spoke single-piece rotors are now available in replica form from Metalgear Australia, and for an even better price than their "K-type" 9-rivet rotor refurbishment/replacement. Makes a person lusty for a dual-disc FIVE-bolt wire-spoke front wheel hub, which does actually exist - but only on the Canadian-spec '77 CB750P Police bikes, a version which used a drum rear hub but the CB750F2 fork and brakes, which were the dual 276mm rotors just like CB750F2 (& CB550, GL1000, CB900F & CB1100F etc) but local cops apparently wanted the wire-spoke wheels & chromed-steel rims. Which makes for some really cool upgrade options for say, a dual-disc DOHC CB750KZ, or 296mm discs & 39mm fork for a CB750F2 - ideally with the 18" front Comstar, like I was suggesting MIGHT be the case on the bike from this movie! Myself, I'm already building some different stuff for my "CB900K0 Bol Bomber", but a 39mm fork with CBX pro-link caliper hangers & some very choice alloy rims for wire-spoke wheels, are waiting in the wings for a light-weight DOHC 750cc build. Meanwhile I'm also trying to "re-invent the wheel" vis-a-vis the COMSTAR - using Akront "Nervi" rims, which are a heck of a lot lighter than the OEM D.I.D. brand rims, plus they were once available in a whole range of sizes, such as 5.75x18" or 3.50x16", etc. Akront Nervi rims seem to have played a role in the early years of the RCB endurance racers, maybe even so far along the line as the RS1000 - It would help to find some hi-def scans of the museum specimen bikes. It would be even MORE helpful, if the MORAD company could bring some of the old tooling out of mothballs, & whip up another batch of "Nervi" rims in just a few sizes. 2.50x18" are out there to be gleaned from some other bikes right now, so a 3.50x18" or 4.25x18" would be a good place to start! If you're at ALL interested in building high performance COMSTAR wheels, for CB-fours or any other type of Honda from that era or any other (2010-2016+ CB1100 with Boomerang rims, anybody?) then perhaps all of us together, by writing individually to the MORAD company, might be able to show them some market potential for re-introduction of such a product line. So too, with CMS classic motorcycle spares in The Netherlands, with that five-bolt dual-disc front hub! They list the thing, but it's not in stock. If it's possible to whip up a batch of replica Honda front hubs, then THIS would be a great place to start. Even if nothing else were different, and one simply used these same CB750A Hondamatic 9-rivet 296mm rotors, well the front wheel would be THAT much lighter, via there being one less rotor bolt in the hub. I really dig the idea of the "stealth" upgrades to the CB750F2 though. Dug up a 2.50x18" Nervi rim, I'm sure a 1.85x19" is out there, am hoping to find a 2.15x18" - wider fatter rims & tires & stuff would be cool, but IMHO the whole point would be to shed the most weight - so either a disc conversion of a CB400T rear drum, or another front wheel with a bolt-up cush-drive? 240mm disc from a CX500/GL500 front end, paired with a "retro-fried" caliper & hanger from CBR/VFR? At the utmost biggest, a 276mm disc on the rear, with a caliper & hanger from the earliest CBR1000F/CBR600F Hurricane. Maybe rebuild the entire seat & cowl with a single fiberglass casting, heck maybe with the gas tank as well? That fake chrome paint on fiberglass fenders? Plastic housings on signal lights. Carbon-Fibre handlebar? It could really add up to a lot of shed weight, which could add up to a lot of improved performance. And to pull all of that off in a more or less stock looking Comstar-equipped '77-'78 CB750 would be awesome. |

I agree that its a Hondamatic by the chrome lump on the clutch case BUT its shown with a left hand kick start and that's totally thrown me as would the film company have paid money for a one off prop motorcycle just so Clooney could kick start the bike from the left hand side ??? I'm very confused. -- Last edit: 2019-04-07 20:34:07 |

Proper title is CB 750 A Hondamatic, this one is a 1978 (Comstars), none of the 2 speed autos (76-78) had a kickstart. |
