G'day viewers, just thought I would ask a question I think of often. What's everybody's point of view on pre 75 dirt bikes made up of bits & pieces kinda like a Frankenstein bike made at home? Would it be a bad thing to take such bikes to CD ? I know lots of people like bling & the best race bikes of the day so I was just wondering. Jimson

Not going to get bling from me buddy. I cant afford bling. What i can afford is bikes i rode back then and they look exactly the same as they did then. with age creeping up on our bikes and knees , parts are getting more and more difficult to procure so a few adjustments are at times required. What i do try and do is keep period correct and as close to the original as i can and as close as my wallet will allow. CD isnt about racing anyway, so i cant see a problem if its just an old dirt bike .

FrankenBikes are way more interesting than show ponies.

No. :)

There are a few pre75 Frankenbikes around. Mostly sideport XL honda motors shoehorned into Bultaco or Maico frames.
A mate built one up from a previously butchered Bultaco frame. Once he had the motor in place, he had to then rebuild the rear loop and shock mounts as they were totally cactus so in reality, the frame would of been scrap if he didn't find a use for it.

I've just about given up sourcing a 400 motor for my 78 Maico and am thinking about going down the Frankenbike route. Yamaha 500?? J

Cool, if I can get Hannibal running right, I'll be there, so if anyone sees a road bike rebirthed as a desert sled from the late 60s early 70s come say g'day. Jimson

Not sure if the 78 Maico frame is similar to the 77, but a mate put a XL Honda motor in a 77 frame and it required a heap of cutting and shutting to get it to fit....and the XT/TT 500 motor is taller than the XL motor

there was a step by step conversion of putting a 500 thumper motor into a maico frame on the net awhile back but alot of work in doing it, its alot easier to use a husky frame as many have done but dont call it a HL coz it aint ;) ;D ;D
-
Travesty! using a husky frame for any purpose than powered by Husqvarna 8)
-
thats only your opinion,seen alot of those "you beaut" non oil pump 4t huskies spit out the big end bearing/cold sieze to know not to touch them with a 10 foot barge pole,funny how the next gen 4t motor HAD a oil pump!2t huskies crack at the back of the cases where the swingarm pivit bolt goes threw but hey their top bikes ;) ;D ask any husky owner ;D

It's better than butchering a Maico rolling chassis. Putting a different motor in any classic chassis is wrong IMO, unless it is something that happened back in the day. While common sense dictates that some parts need to change especially for racing reliability making bikes that never existed is wrong.

One of my pet ideas is a GMC 74 Maico frame with a Yamaha SC500 motor . I would use the MX360 5 speed gear set and a YZ 400 D cdi . Just thinking out loud . Iain
-
get GMC to build it without the engine mounts. at least you wont have the maico,monty and husky police on your case for using the gen frame ;) ;D and killing another bike ;D

That would be a winner for sure Iain.

thinking along a simular path with a DT360 for a pre75 sidecar that is very slowly comeing together, was looking at the YZ400F with keen interest wit its 82mm bore and 75mm stroke
SC500 95mm x 70mm
all other 400's 85 x 70 then there is the 425 and of coarse the 465 85 x 82 thinking thinking ????

How many here saw the DR600-in-Husky-frame-with-PE-swingarm special at Beaufort or Tallarook vinduros? It's a ripper!

-
it was a cage rattler and a few bit ;D seriously, the earlier huskys were good for transplants except the chain is on the wrong side so a flip is required. but they are big in the engine area to accommodate the 125 / 250/ 500 as required and is usually whey they are used for hybrids (the spark has gone from the original motor...). after a heap of laps (slow ones) at CD12 I can confirm the aircooled twin shock 510 is still a camel :-X
-
This bike is somewhat newer than 1975. I built it for the CZ World Championships here in the states back in the early 90's. It ran in the unlimited class.

Have seen that photo quite a few times, always impresses me how together it looks. If you didn't know better you'd think it left the factory like that
-
how together it looks
those words Tony are the perfect description of a GOOD frankenbike.

How so? Isn't that how bikes came to be in the first place.
