MV Agusta disc ID please

[jellywrestler]

brought a set of seventies MV Agusta wheels with this rear disc attached, need it identified please. Not sure whether the disc carrier belongs with the disc or the wheel, any clues folks?

The last time I saw one, the shape and proprtions of that one, it was on a Yamaha 250cc Superkart :mellow:

[Grumph]

Well, Husa can't find it from the suggestions i gave him....looking at it I reckon it's not a homemade as it appears to be iron - and you don't make CI discs at home.
Maybe adapted from another application - I'd pick it's too big for a kart though. Formula Ford ?

[husaberg]

Its the inside carrier with the 5 bolt holes that throws me, that aside the disk looks more BMW to me.
oh it looks like r90's had 5 bolts

later ones had similar disk shapes

so maybe mix and match

All the BMW models had 5 holes from the R75/80/90/100 but it doesn't look like a BMW carrier

I also doubt a disc from that era would be attached by cap screws they were generally all riveted and not many were drilled either

have a look at it closer, by the look of it, its a bitz of this and a bitz of that.
BMW is the closest I can find.
although Laverda rears are also 5 bolt deep dish and drilled.

Doesn't ring a bell. Only Marsh's I've ever known in the bike world are Warren and his dad...
If they came from Don did he say they came from canty ?

[Kickaha]

Got a picture of the back of it and some dimensions Spyda?

I'm never mentioning another name to you on here - you always come back and say he's either dying or just died....

I've gone right off you, the McIntosh looks fucking gorgeous on wire wheels

we spent 75 years getting bikes of antique spoked wheels, and he put us back in the dark ages.

which are really just a copy of the gs750 ones of the time, nothing special and you need a keen eye to tell the difference, he also built the mcintoshes with imperial measurements, not metric too!! the first show bike had mags on it, what does that tell ya?

Maybe as the guy who designed it he had a specific reason for doing so, it would be interesting to know why

edit, lighter weight than the readily available cast alloys of the time or better rim widths?

The reason IMO was availability. Plenty of guys here who could build spoke wheels. And DID had the rims available.
Very few mag wheel makers around at the time - Morris would have been what he wanted but you had to have US dollars for that...
No internet remember - and no credit cards where you could just ring up and charge it...

if I can find it I will dig it out , But Ken had a bit of a fetish about the spoked ones at the time, same with the twin shocks.
I think it was to do with the costs plus I guess he could make his own for basically nothing, also rebuild them if they were damaged
I think I have posted it before, its a bit humidity damaged though.

The 1983 Aussie dollar retail for the Kit was $3199
That included frame including mounting bolts swingarm and bearings and chain adjusters fuel tank and cap upholstered seat, footrests and controls, handle bars, yokes, steering head bearings, fairing and screen inc mounts, indicators, front guard, S&W shocks and a tail lamp. The first 5 kits for the Suzukis also included a custom made Megacycle exhaust for free.

The Wheels on Hiscocks were at the time $2000 NZD.
the spoked wheels Ken sold to punters for $900NZD were the same weight.

Can too.. Mate had a K100 BMW (had a hard life prior to being purchased as a write off*) anyway the disks were worn way under warrantable thickness, replacements were turned up out of Landrover flywheels and worked really well

* among other things, it had dropped a rod racing in the six hours at manfield.

McIntosh didn't have the resources to make bikes, and as mentioned wheels were an easy option to provide and more work through the shop, easy work too.
when you brought your kit you could use a katana or gsx to donor wheels, buy Mcintosh ones or of course buy flash wheels. i'm not ante the wires, just prefer the others, still, it's going together with the wires as is as the wheels i brought are five bolt, whereas the ones on it are six and i can't be arsed tracking down other stuff at the moment, would rather get her up and sorted as it is/was. mine is 007 so would have been sold in one of those first five with the megacycle pipe, i picked a genuine McIntosh megacycle in aussie last year, Ken McIntosh has it at the moment as i suggested he might want to offer a period pipe with his latest run of Bathurst Replicas, rather than fit modern carbon fibre/titanium ones.
if he doesn't i'll grab my pipe back and get on with copying it anyway.

It rings a bell yes.....
Remember you asked how I knew that last year

Mick Hone was selling the first demo bike from the kit which included $2500 worth of Yosimura engine bits and 33mm smoothbore carbs, marzocchi forks and Brembo brakes and disks and EPM mags for $9000

where did that info come from out of curiosity?


MCM
I was going to post it but its pretty hard to read (as they were newsprint then) there is also a write up on Ken produced at the same time that would be even harder to read in I think Two Wheels.

If you click on the attachments a few times they will super size. ie about 3 times
next time I come across the other article I will post it warts and all.
its not this one but that would be worth finding too.

BMW PDC is 79mm and after looking at alternatives unique to BMW.

Suzuki GXR 750 are close.

Measure the PCD and google that, will narrow down the search.

I prefer spoked wheels over mags on classic bikes, in the 70's they just bunged mags on and hey " We're hip".

Dark ages? Motorcycle are only for developing nations, until you can afford a car. In 20 years they will probably be consigned to the archives.

there was nothing classic about the McIntosh when it came out, i remember seeing dallas rankines harris with dymags and thought they were the sexiset wheels ever, just a personal repference and as stated the wires were an option if you couldn't afford mags... although too this was the era when the wires were the go on the hot gsx's, there was word that it was to introduce some flex as the frames were getting more rigid as well as the tyres at the time
