Bikers of a certain age will remember:

A clatter of Triumphs.

A clutch of BSAs.

Maybe even a handle of Nortons.

Now sadly it's a museum of British motorcycles.

Any more?

After an excellent landing etc...

A pounce of Panthers.

A whisper of LE Velocettes.

A veneer of Vincents.

A square of Ariels.

A mass of Matchlesses

A Lump of Lambrettas

A Void of Vespas

A buzz of Frannie Bs?

A sty of Harleys.

After an excellent landing etc...

A sneer of Excelsiors.

A cluck of Bantams.

A Superior of Broughs.

A ray of Sunbeams.

A tribe of Indians.

A pack of Corgis.

A squadron of Black Knights.

A duple of Douglases.

A jumble of Jameses.

A procession of Royal Enfields.

A giggle of co-pilots

A grouse of AEOs

a dump of Hondas

A lying of politicians

Blast!
603 mentions the one that got away.
Some one gave me an LE Velocette back in the 60s. He couldn't get it going. I was reasonably good at getting bikes and scooters going. When I'd finished the two Vespas that I was working on, (both successes), I turned my attention to the Velocette.
After all the obvious steps, I had made no progress.
So I took the whole thing apart and re-built it.


I could get a spark and petrol in the right place, but not frequently enough to get any more than a cough.

I never got it going.
I had forgotten that. I clearly have a brilliant selective memory.

Perhaps the designation LE (from 'SiLEnt') was particularly apt, for your dud example!

To revert to the OP's intention of British motorcycle brand names;

A hyphen of Francis-Barnetts.

An invasion of Normans.

A skirl of Scotts.

A McFaggot of Scots if yesterday's news is anything to go by.

A wunch of bankers

A shedload of Shuttleworth Snaps

That reminds me, when in college I gave a friend a lift home because his bike was 'under repair.' His bike Vincent (1000cc) was in his living room, he lived in a second floor maisonette.

A settee of Vincent parts.

A Majestic Riviera of Dunelts!
Or a Royal Deluxe,

don't the old names have a wonderful ring of glamour to them.

a box of frogs, as in "she's as mad as a box of frog's"

Maybe a quack of Ducs?

After an excellent landing etc...

A Frantic of Fantics

The Fantic Caballero must have been the original 'Crazy Frog' bike, 'ring, ding, ding, a, ding, ding'...

What's the collective noun for a collection of collective nouns?

Picked up an excellent one the other day. Apparently Margaret Thatcher was hosting a dinner while she was PM and all the previous living PMs were in attendance. In the banter following dinner someone asked, given the company, just what was the collective noun describing such a gathering.

Harold MacMillan, quick as a flash, said: "A Lack of Principals"

What's the collective noun for a collection of collective nouns?

errr....a collection?

Many years ago I watched a good natured hissy fit between two smart gay guys and after one had said something like "You're such a girl, such a queen such a slut" and a few more wonderfully descriptive words the other came back with, "Oh such a nonce of nouns!"

That has been my collective for nouns ever since

A juice of PPRuNe-threads?

A school of teachers.

A rug of receivers

GGR

A Bacofoil of Conspiracy Theorists

a collorectum of a$$holes

A parlour full of PPruners babbling

A Loop of programmers

An Indecision of Analysts

An Abscence of Managers

A Lay of Punchgirls

Anyone got a suitable term for 4 pushrods found wrapped up in an oily rag when you have spent an hour or so pushing the unresponsive bloody bike after a rebuild?

I used a few, but never seemed to get anything really appropriate.

A ******* bastard of pushrods
