CB750 Aftermarket Frame
« on: February 13, 2007, 07:57:24 AM »
Is there an aftermarket frame and swingarm available new for CB750's? I haven't been able to source a used Seeley/Rickman/Bimota etc. frame. Vaguely recall somebody posted info about swingarms available in UK.


Anybody speak French?? Maybe one of these specialists still in business?

Dunno but someone on here had an autocad or similar drawing of a frame they were working up.

I've been toying with the idea of building one after the frankenbike is done but thats at least a year form now for anything finished.

Looking for something lighter, stiffer, and more motor accessible while retaining the classic lines and recognizability of the 750.

Roger Titchmarsh in Yorkshire UK produces authorised Seeley replica frames nowdays. Top quality workmanship, and a very knowledgeable guy too.

Hi 736!  Is that an illustration of the Bimota HB-1 frame?  If so, where did you find it, and do you have a larger version you can post or email?  Thanks!  RR

My frame design is quite a bit different. Based on the featherbed design with a few twists.
Probably not as astiff as that design he posted above, but def more retro looking.

Between the shot of that Seeley and the 3D rendering of that custom frame, I believe this is the coolest thread I've had the pleasure of reading tonight.

That page is basically the same as satanicmechanic.de

Anyone ever seen a SOHC 750 engine used as a structural (stressed) member of the frame? I doubt that the old castings would hold up but just curious.

I translated the French!
Check out frame sausage!!!

Honda CB750 was where one of the most transformed motor bikes, that it is on the level of the engine, but also of the part cycles. Engine, in order to often exceed the 65CV (by increasing the cubic capacity using kits engine: 810 Motor Elite, Motor Speed or Read Titan, 888 Mahle, 900 Wiseco and I pass from there... and why not one 969 Japauto! ). And finally of the part cycles, for a more powerful engine, it was obviously necessary to replace the framework "sausage" of the CB after of course having tested the reinforcements, the shock absorbers of direction... It was also necessary to fill its wallet and there one had the choice: Martin, Rickman, Dresda, Egli, PEM or for rarest Corki, Zerchot, Seeley, Dholda, Chatelard, Guédon, Rob North, Nico bakker and why not Bimota! But, if finances did not follow, one could fold back oneself on the polyester sets for frameworks of origin: Rocca, Dunstall, Bottelin, Chaplot or Motor bike Sport Design and I forget some... Here some photographs taken randomly in reviews or at the time of demonstrations of old motor bikes.


BIMOTA One of most beautiful the coffee-racers built around this engine with its typical oil tank placed behind the tubes of exhaust. Its name comes from 3 impassioned Italian: BIanchi, MOrri and TAmburini. Only one ten specimens would have been built.

CHATELARD Gilbert Chatelard built some frameworks in the beginning of the Seventies. This craftsman was installed in Paris area, his framework was assembled without any curved tube. The oil tank in the shape of box was interdependent of the framework.

ROPE-MAKER Alain Cordier, Marseillais, more known for his qualities of driving mechanic and preparations (ACM), produced some frameworks for mechanics 1000CBX but also for CB750 of which the lattice surrounding the engine resembles to Martin a little. or in Guédon.

CORKI Lucien Shoe-maker of the store Corki Motor bike to Sucy-in-Brie, created a part cycles with framework beam. Sold with large turntables moulded and siglées as well as a hull polyester, splash plate with aileron and reserve of a capacity of about thirty liters

DHOLDA Jean d' Hollander, large concessionary Honda in Belgium, carried out parts cycles rather complex, especially on the level of the back suspension with deformable parallelogram. These machines with Honda(CB mechanics, RCB, RSC...) were primarily used in competition, where they were often in the 1st places.

DRESDA Dave Degens, English, marketed FeatherBed executives assembled on Norton. A framework of its design was selected for the 3 Japauto of bowl 72 but were not preserved the following year. On left, part cycles of 73 and Dave Degens always Re-manufactures at the request of the executives, like this one on the right, for CB 750, carried out in 2003.

CKERT Roland Eckert, concessionary Honda German, produced this superb machine. In more of the part cycles (tallies, fork, arm and wheels), it boostait also the engine by reboring it like Japauto to 70 mm and by modifying it by adapting certain parts taken on other models of the mark and others of its design.

EDLER German Motocist who carried out this splendid Cadre coffee-racer of Egli inspiration and preparing aluminum.

EGLI Fritz Egli, this craftsman Swiss designed a framework effective, beautiful beam and of good reputation, in particular in 1966 with its 1st part-cycle on basis of engine 1000 Vincent. The originality is that it acts as oil tank, equipped of an additional tank. The oil circuit can contain 7,5 L. Still a patent house, the fork "Egli-Racing" ' of any beauty with its 2 transverse reinforcements.

 . GUEDON Craftsman manufacturer originating in Hollow, Michel Guédon built very few specimens on basis CB750, it adapted to the chart preparing, fork, wheel and brakes on his frameworks. Its name is known partly for its prototype motor bike with engine PRV(V6) JAPAUTO In 1972, Japauto designed and manufactured this prototype, baptized "the panther", in its workshops with Levallois.. The oil tank was in the bottom of the framework and not in the beam.

 MARTIN Surely part-cycles special for the most widespread CB750. 2 types of framework produced by George Martin. 1st model: tally beam of the Egli type, 450 ex sold all confused marks (Honda, Kawa...). MARTIN 2 Another with side structure and suspensions cantilever which one also calls tallies "lattice". These 2 models were made out of steel 25CD4S and were equipped with a polyester hull, many options were proposed.

NIKO BAKKER Dutch, old Motocist pilot, built executives lattice type. He has, amongst other things, prepared the motor bike of Gary Green for the season 73 Il is always in activity and product of the executives for the modern motor bikes.

PEM ACM A cocktail of Edouard Morena for the framework and Alain Cordier for mechanics. Executives PEM are regarded as rails and were assembled on many machines of race of which Japauto, which used them during nearly 10 years, from 74 to 83.

 RAU Manfred Rau manufactured some frameworks beams strongly inspired of Egli. German Motocist still today,il assembles some frames for engine GSXR.

 RICKMAN Gift and Derek Rickman designed a superb framework whose characteristic was to be able to preserve a maximum of original parts, including the 4 pots. The nickelled framework is made out of tube renolds of large section. The adjustment of chain is carried out on the axis of arm AR by 2 eccentrics, which makes it possible to have a perfect alignment.

SEELEY Colin Seeley manufactured a framework for which, like Rickman, one can preserve the majority of the original parts, except saddle and tank. Very rare in France, it is conceived out of tube Renolds 531 of diameter 17 and does not weigh that 12 kgs is 4,5 less than the origin, the arm is of diameter 14. Seeley had also modified a CB750 F2 in "Read Réplica" at the request of Honda GB.

ZERCHOT Roland Zerchot designed this framework of quality for CB Four, one of the advantages is to be able to dismount the cylinder head and the cylinder without depositing the engine. Reception

...check out http://cycleonemanufacturing.com/ They do chopper frames, but I'm sure they could build what you wanted in a racer.  They build their frame to spec, so you could give them the rake/stretch ect you wanted, and they sould build it.  Not sure if the swingarm would be problem or not.  The do mostly hardtails, but would be work a look see.  Kate works up front, and shes great to work with.

Anyone ever seen a SOHC 750 engine used as a structural (stressed) member of the frame? I doubt that the old castings would hold up but just curious.

Tony Foale frames used the motor as a stressed member. There was a french company (moto..something) that used to make a cb750 frame where the engine was a stressed member also. It isn't that uncommon, even as a part of the frame the engine doesn't really undergo all that much stress unless the swingarm pivot is attached to the back case or not supportedly properly.

Edit: Left out Egli, they made SOHC frames that were stressed members also. One source to consider is Harris in england. They made all sorts of frames (mostly for DOHC) and the harris magnum is dead sexy. They will custom build any trellis frame for you for any engine and can even build replica frames. It will be expensive though.
