Various Seeley Frames (Mks)

There was a nice story and interview on Mooneyes Cooper in Classic Bike several years ago.

The Yamsel was actually his idea and it was raced in 1970. In 1969 Cooper had the Seeley Mk3 AJS7r single that handled like a dream but was slow, and he says because the Yamaha 350 two-stroke that he wanted was not available in the U.K. then, he had to have Barry Briggs bring one over that year from the USA. which was fast but did not handle so well and he crashed it at Cadwell that year. So he came up with the idea to put the Yamaha two-stroker into the Seeley frame.

Seeley only supplied a couple of bent up down tubes and Cooper and a guy named Ron Herring built the bike up. He lost the first race with it because he had the wrong gearing, but then got a close-ratio box for it and won his next 39 races, Wow! The Yamsel weighed 240lbs wet and had 54 horsepower.

The 1997 interview told that Cooper still had the "1970 Yamsel" and also his 500 Seeley-Matchless, which is "the second ever built and the most original in existence".

Sadly I heard that a few years ago Cooper had a break-in and someone stole a bunch of his old racing bikes, but I do not know the details. What a shame something like that has to happen.....

Hi all

Just thought I would mention that as Seeley920 said the picture from Beng of the Seeley with the orange exhaust is a Jim Lee frame. Jim built frames & his rider (in the photo) was none other than Mick Grant. I have to say a few words in support of Jim Lee, as I am the proud owner of one of his frames.
I was not allowed to race it with the Classic Racing Motorcycle Club at the time as I could not prove it was raced prior to 1973. Jim was amazingly helpfull. He told me that they never numbered frames as they were too busy going racing. Building & racing bikes & all that in tales. He never thought that people would be asking questions about them 25 years later. They were just racing!!! Micks helmet logo is JL he raced with it for his whole career IOM TT Works Kawazaki works Suzuki Works Honda GP oval piston NR500.
Jim said he would ask Grantie about my frames history. Mine was built for Crooks Suzuki. Eddie Crooks was a sponsored Seeley Team :D :D :D But he could not get enough equipement from Colin so he commisioned my frame for Stan Woods to ride. It was withdrawn with a crank problem!!! (not) After Colin had seen it!! The next season Eddie ran 250 350 500 Seeley Suzuki's & Seeley Commandos. I am only missing the name of the man who brought the Suzuki T500 engine bike at the 72 TT & fitted it with an 8 valve Rickman T120 Bonnie engine for F750. It turned up at Steve Wynnes (Hailwood Ducati fame) shop but he cant remember who he brought it from.

ps a lovelly fella (Seeley 920 will laugh at that) within our club brought a Goldie a few years ago, & was asked by the seller if he would like the scabby frame with the orange exhaust as well? :D :D
It is going to be resurrected soon.

all the best Chris

Next Questions:

I have seen several examples of a Seeley single disk front end but were there any Seeley dual disk front ends?

Did Seeley really go into the manufacture of forks or was this a third party arrangement for Seeley?

I think I've posted these pictures somewhere on this site before, but can't seem to find them. In any case, this seems like a good thread for them. These are shots of the Caffrey Vendetta Seeley style frame that John built for Martin Adams back in the early '80s. The one with the fairing removed was taken outside my house, and the other two are from Daytona 1987. The rider was Paul Lewis, aka The Angry Ant. The engine is an 872 Commando with lots of trick stuff.

I was always under the impression that my Mk3 was made in 1966, and I think the frame number has '66' in it.

I believe the original forks used on Seeleys were made by Metal Profiles.
About the Yamsels. There is one here in Australia, still in Albury but never raced. It was extremely competitive in A grade races in the early 70s. It had a TR3 motor, with another with the gear box removed, welded on top so that both cranks engaged the clutch.

Love that Seeley Weslake, every boy should have one. Why has it got lights ?

[quote="hobot"]Modified Seeley BSA racer These two shots are of a MK3 Seeley chassis with a BSA Goldstar engine and Quaife 6 speed transmission. My friend Craig did the basic engine installation, and then I did a lot of the detail work, including the extra frame bracing. The bike's owner said the bracing firmed up the handling noticeably

There was a really fast A grader used to ride a Seeley G50, told me that he felt the Mk 3 was wandering in the front end. I use a single gusseted piece of chrome moly pushbike tube in the front of mine, and it always feels positive and nimble.

Hi Steve , I had the figure once, but forgot it ( age ?) , but nearly the same as the Commando which is a light frame as you know it....but as it got less ancillaries (isolastic,z plates,and so on ...) the final is far less heavier, including most people fit alloy jugs, belt drive , alloy rims, alloy tanks..........

One more interesting tidbit for those who are offended by certain racing organization's view of history - AHRMA doesn't necessarily limit bikes to '72 and older, they can be newer as long as they are "like design".

AHRMA's policy is that the RACERS police themselves when it comes to class compliance. Round up 100 old guys that want to race their homebrews and ask them to rule out other competitor's bikes that they believe aren't "like designs", or otherwise don't conform to the exact "letter of the law". I believe there's a fella that's been posting in this thread that might make a few "friends" in a big hurry.

Ugh, Martin I mean how much do these Seeley's weigh by themselves. I keep seeing claims a big Seeley advantage is weight savings over the iso frame so would like to know how much they weigh as I know what Combat frames weigh. Of course a solid frame will handle better than un-tamed isolastics but the fastest bikes in the world now make frames flex for side loads on purpose, so maybe Seeley ain't all that better that way either. Do the Seeley flex detectability?

Although grandpaul may be a member of AHRMA, I want it to be clear that grandpaul does not speak for nor does he represent AHRMA.
