Brief History of the Marque: Zenith
Made in Finsbury Park, London from 1904 to 1950, Zenith motorcycles had engines by Blackburne, Fafnir, Green, Green-Precision, Villiers, JAP and Bradshaw, usually with drive by Gradua belt and pulley system which was retained into the 1920s. Notable models include an oil-cooled horizontally opposed Bradshaw-engined twin of 1922, and JAP V-Twin engined racing bikes which achieved considerable success.

Picture from the first world war
Just thought you might like this photo of my grandfather on a zenith of some kind. He was a captain in the Army in the first world war, where he was awarded the Military Cross, and he was a Squadron Leader in the second world war. His name was Reginald Mayo, and his grandfather Edmund Mayo was the founder of the Coventry Eagle Motorcycle company, which started life as Hotchkiss, Mayo and Meek, Hotchkiss being an American machine gun designer and manufacturer.

Zenith information; Super Kim and Argentina
Zenith KTOR supercharged
There was a query about 'Super Kim'; I have written extensively about this machine on my website; www.thevintagent.blogspot.com
I have also researched the life of Freddie Barnes; search around my site. The history of 'Super Kim' is now almost fully documented, although there is a period from 1925-1929 which is vague. The Sigrand family may have purchased this machine directly from Zenith, or did they buy a used Brooklands machine? I'm in contact with the family in Argentina, and we're trying to work all this out.

Spotted this today.
Zenith not sure
I was working today, at a place called Zenith House in Manchester. They had this in the foyer. Sign says it's a 1912 Zenith. It's a JAP V twin, with a variable seed belt drive. Apparently it was the racing version, but this one had lights and a sidecar.

Thanks in anticipation,

A friend recently came across a photo of his great uncle Sim sitting astride a Zenith Vee twin sidecar outfit. The registration number is BC 1595. Clearly a Leicester, England number. Does this machine still exist?
Following my earlier e-mail regarding Uncle Sim's Zenith, please find
Thanks in advance for your help

The picture of the man sitting astride the Zenith motorcycle and sidecar, Leicester reg no BC 1595 is a friend of mine's Great Uncle Sim. My friend still has the original photograph wondering where this copy came from and if the motorcycle is still around.

JAP Supercharged Engine
SUPER KIM - ZENITH
Do you have any information regarding this motorcycle ?
I saw it years ago in an auction site - I lost the best picture of it ... Any details would be appreciated... Thanks, Greg Asmussen - Australia.
It would be interesting to find out the history of the bike - I think from memory it was used in some speed trials in Brazil at some stage of its life......
Very interesting machine though - with the Garrett Blower attached and
carby bowls mounted so low on the left side - definately not for left hand

Where is it now?
A few years ago I sold a Blackburne engine. Some time later another chap had bought it and contacted me, saying that it was one of only four made, a 1000cc and fitted to a Zenith motorcycle. He told me that it was rather famous in it's time and set a lot of speed records back in the early 20's. He had reunited the engine with the frame and built the bike; he invited me to ride it at Brooklands but I was too unwell to do so. Curiosity is making me wonder if anybody knows anything about this bike and where it is now.

There are some queries on this site from NZ/Australia re Zenith.
A chap who belongs to one of the Kiwi Vintage or Veteran car clubs (whichever one it is which has the really old cars) has a restored Zenith - perhaps 1908-1912? - with a 500cc JAP single engine. I just met him at a function in the Manawatu district of NZ about a decade ago, and I think he may be from the South Island. Someone in NZ vintage or veretan car clubs will know who he is

I came across this frame at a swap meet, trying to get as much detail
about it as possible. Frame number is 10424.
Any help would be much appreciated.

1912ish? Racing single
Hi, we live in New Zealand and would like to know the email address of any Zenith motorcycle enthusiasts or club as we have just bought an unrestored factory race machine of about 1912-14 (single cylinder JAP). Missing very few parts, but would appreciate the right contacts. Will post some photos hopefully soon. Thank you very much for any help, as it is very hard to find the right sources from this side of the world!
I don't know of a Zenith club, but suggest contacting the larger clubs in Australia and the UK to ask for contacts with other owners.

Zenith OHV JAP Racing single
Here are the promised photos, hope they are of a decent quality. The bike is an OHV track racer, however it has very different handlebars to the pictures of racers we have seen to date. These handlebars appear to be very genuine though. The frame/petrol tank/ and engine (not pictured) are also off the racing model. Frame number is 771, no other numbers appear to be visible. Does not have "Coffee grinder" unfortuneately. Would love to gain any knowledge from readers of this article, or leads to find appropriate parts.

350cc Zenith in 1929 raced by RNM Grounds
My Dad raced a Zenith in 1929 on Forbury Racecourse in Dunedin against a moth flown by Captain Bolt. I'm trying to find any information relating to my Dad's racing in the 20's. I have photos too!
I've included 2 images, one of the racetrack with my father racing the moth and a closer view of him on one of his bikes [a New Hudson]. I hope the quality is ok.
