1968 Seeley 7R







The seller has put this winning AJS 7R back on the auction block. Back in March the weather might not have been a factor to help move this Vintage racer from one garage to another. But now the sun is out and the Vintage racing Schedule is upon us, you have a second chance. 


I’m sure that there has been something that you really really want, but the whole money thing got in your way. But wait, I have something just like the thing I want, so if I sell it, I can get the thing I want. This is the felling I got when I saw this 1968 Seeley 7R race bike for sale. The seller seems to have taken some quick pictures of the bike on the lift, give a short description, and throw it all up on eBay? Wonder what the seller has their eye on?


From the seller

This bike is a Colin Seeley framed AJS 7R 83mm bore short stroke. This is a well known and respected bike in the AHRMA paddock ridden by Bruce Yoxsimer and campaigned to 3 National Championships. With 5 Daytona wins and countless wins around the country, this is a very competitive machine.


Colin Seeley was a motorcycle guy who apprenticed at Vincent Motorcycles, went sidecar racing, and then got into the frame building business. And business was good. Taking advantage of the dying British motorcycle industry, he was able to buy up all the tooling and spares from AMC for the Matchless and AJS brands. He tuned the 350cc and 500cc singles and put them in his frames and offered them to any weekend warrior who wanted one. This racer has the 350cc AJS 7R heart powering the Colin Designed racing frame. And it’s the Seeley name and not the AJS name that propels this bike.

Of course the bike has a full spares kit including several pistons, valves, ignition, full rack of gearing and jetting. Detailed records and tuning notes. Head was just done mid season 2012. New seats, guides valves, etc. Piston was done at the same time, so essentially this bike is ready to roll. I will provide a new set of race rubber for the new owner. This machine is amazing to ride and race. It has a lot of very special bits that I would be happy to discuss one on one.



Today vintage racing is big, and you can make a large fortune into a small fortune very easily. The seller looks to have spent more then just a weekend here and there racing. They have amassed the spares you need for a full campaign. So if you have the impulse and need a turn key vintage racer, this 1968 Colin Seeley 7R might fill that need.

1957 AJS 7R Boy Racer

There was a time in European racing when Manufactures handed their motorcycles off to racers, and they went to join the Circus. The traveling show that when to Monza, Imola, Nurburgring, and the Isle of Man. These men would race motorcycles with displacements as small as 125cc, the Junior motorcycles of 350cc, and the Senior 500cc bikes. This 1957 AJS 7R was called the Boy Racer because of is 350cc displacement, but don’t think that this boy couldn’t scream.

From the seller

The bike was originally delivered in England and was exported to Australia in the 1970’s according to the records its engine number is 1557 ,which is a late 1957 build ),I bought the bike in Brisbane from a guy in 1986 it was completely un-restored he had bought it from the guy who originally imported it from the UK, it reputedly came from a Midland motor museum and was ridden by Bob McIntyre but i have no documented history of the although the engine was well prepared and had “works type” crankshaft with carbon steel balance weights etc  ,after purchase I proceeded to restore it to race in historic events, after we retired the machine I stripped it completely and fully restored the machine   to the condition it is in today  the price reflects the condition and attention to detail and is competitive when you consider that a similar machine sold for 46k sterling in the recent past.

AJS had been racing and winning with overhead cam engines since before WWII. When racing started back up after the war, designer Phil Walker designed the new 7R and factory riders got exclusive use of the new bike from 1948 until 1954. With improvements almost every year to valve angles, and for a short time the number of valves (7R3), crankshaft length and design, and bore and stroke, the AJS may not have dominated, but they did compete.

After 1954 AJS opened up their race doors to privateers, and the Boy Racer found its way into the hands of enthusiast. AMC was the parent company of AJS in  1954, and saw that factor money spend on racing was not profitable. But this did not stop riders from taking the prize with the AJS 7R. Wins in 1961, 1962 and 1963 at the Junior Manx TT showed that the 7R, factory backed or not was a track weapon. By the final year of production in 1963 reported power output was 40bhp.

The seller of this 1957 AJS 7R gives a break down of each major system that makes up this bike and how it has been restored, revived, and invigorated. This 7R shows you not only how well bikes were build, but also the continuing support of individuals for these vintage motorcycles, and getting them on the track and competing. BB

Instant collection #2

Camano Island is going to be known for more then just the Barefoot Bandit Colton Harris-Moore after . Offered for sale are some of the best Grand Prix racing Motorcycles known to man, AS ONE LOT. Bikes that readers of both RSBFS and CSBFS have dreamt about owning, and now they can.

The first bike that caught my eye was the AJS 7R that heads up this auction. The 350cc bike was called the Boy Racer, likely because the 350cc class was called the Juniors to the 500cc Seniors. Developed by AJS after the war, the chain driven OHC engine developed 32bhp at 7500 rpm and would push the bike and rider to 120mph on the right track with the right gears. Between 1948 and the end of production in 1963 improvements to the engine were made, and a 3 valve engine was offered in 1951, called the 7R3 adding 8hp and 300rpm.

Part of the history of the British motorcycle industry, companies would combine but kept the marquees separate. This is the case with Associated Motorcycles (AMC) which joined AJS and Matchless. Having more then one Company under one roof allowed the 350cc AJS 7R to grow up and become the 500cc G50.

The Matchless G50 offered for sale in this collection is a 1965 Richmand/Kirby combo. The G50 engine got its 51bhp with the 496cc single overhead cam turning 7200rpm. Don and Derek Richman made frames for many different engines, and were able to sell them because they were good. Kirby appears to be a team that raced during the 1960’s in England. For better or worst, both the Rickman frame and the G50 engine are being reproduced today, using the original designs but with modern technology. 

The Norton Manx was another world beater during the 1950’s and 1960’s. Offered in both 350cc and 500cc over head cam engines, the Norton used its famous featherbed frame to dominate GP racing for many years. The bike offered in this auction has the 350cc engine, but also comes with a Dustbin fairing, that was banned by the FIM as a hazard to the rider. With the 348cc you would get 35hp with a top speed of 115mph, (likely naked). Again like the 7R and G50 the engine from Norton went through development over the years, but the basic overhead cam layout stayed the same.

This is a collection of three motorcycle, from three companies (well maybe 1 ½) who went racing in the 1950’s and 1960’s, and won. If you wanted to collect the best examples of the time, these three would be on a very short list. And if you are someone who likes to ride their vintage bikes, these again would put you in a very good position to win in vintage races.
