1967 Triumph T.T. Special Factory Racer

1967 Was the final year that Triumph produced the fire breathing T.T. Special. The T.T. was a souped up Bonneville featuring High Compression Pistons, Sports Camshafts, 1-3/16" Amal Monobloc Carburetors, Energy Transfer Ignition, full bore Exhaust Pipes with no Silencers, Lighting, Horn or Speedometer. A bike destined for T.T Racing in the United States, all but a few were sent to either Tricor in the East or Johnson Motors in the West. It is said that there were 1200 or so machines produced for '67, a batch of these were produced with early 1965 style Steering Heads with a steeper 65-degree Angle which were favored over the Head angle that was introduced for the '66 season. These Frames are identifiable by the lack of Fairing Lugs, the Steering Damper Anchor Plate mount as well as UNF Threads all over (which made them different from the 1965 Frames). Unfortunately although requested by US Dealers, the 1968 T.T. never went into production which is a great shame because it was destined to have this early style Frame, Alloy Rims as well as a central Oil Tank. The topic of these Frames is still a grey area because no paperwork has been found to back up this batch of machines but it can now be said after a good number of these bikes have been discovered even the most skeptical experts have now come around to the fact that these were factory produced, all the machines so far are within the same batch of serial numbers and were produced in December 1966. A link to a British Motorcycle Forum can be found at the end of this article which has an interesting thread on this subject.

Aubergine and White were the colors for 1967 Bonnie's, although the first batch came with Aubergine and Gold. The change came at engine number DU48157.

The Triumph Logo was introduced onto the back of Seats in 1966, this cover is New Old Stock and shows this logo exactly how it was. The seat is a very important detail to me on my restorations as I find that many restorations are spoilt by a couch looking saddle being employed.

Pictured below is the bike as I found it. Advertised as a 1968 TR6? I went out to see it anyway. Instead of a TR6 was a 1967 TT! Sold with the original California Title.

Some photos below were taken during the restoration. After a dry build to check the fit of the cycle parts and to insure all hardware was present and correct.

The competition machines such as the T.T. and TR6C were given more efficient Damper Rods that were not fitted to the road bikes, a worthwhile upgrade for 1964-1964 models.

1966 Saw the introduction of a lightened Flywheel, it was said to improve off the line performance although was discontinued in 1968 because of addition vibration concerns. This Crank was dynamically balanced.

Don't think I have ever had one of these motors apart and not had to replace the High Gear Bush, not due to internal wear but because the Clutch window Oil Seal hardens and cuts a grove into the brass rendering it useless for sealing oil. T.T. Specials used a 17-Tooth Countershaft Sprocket unlike the road bikes which used a 19 Tooth.

High Compression Racing Pistons by Robbins.

Energy Transfer Ignition allowed the non use of a Battery. The E.T. system is frowned upon by many but when set up correctly can be a good set up although the Coils are very hard to come by nowadays.

Original Dunlop Rims were restored, very pleased with the deep manufacturers stampings that survived the re-plating process.

Original Amal Monobloc Carbs were retained and restored, each having correct numbers and date codes.

Below are a few shots of the bike just before it was delivered to it's new owner.

Check out the interesting threat on these T.T.'s

1955 AJS Model 18CS Desert Sled Scrambler

After several months of chasing this AJS I finally was able to purchase it and introduce myself to the world of the Big British Single. This will be something new to me as I have always been more of a Twin Cylinder enthusiast. 

This is 1955 Model 18CS, a 500cc OHV Single. The CS stands for Competition Spring Frame.

Shipped from the factory as ready to go racers, they were very successful in both Scrambling and Desert events. This bike was registered for the street with the addition of a Head Lamp and Sparto Tail Lamp although there is not one wire on the bike! Purely to stop getting hassle from the man whilst out riding on the street I am sure. 

The CS Models were built in the AJS Race shop, basic Model 18's were taken off the production line and were given the business to produced a highly tuned thumper. Only around 200 CS's were produced   each year.

Love the hand painted graphics on the Alloy Tank, originally it would of been black with gold decal and lining.

Spark provided by a Lucas Racing Magnetos, a beautiful item, green tag and all.

Competition Oil Tank bares the decal from the original dealer who sold it new, Hunter Miller Motorcycles of Bellflower, California, mainly a BSA dealer.

I have a receipt dating from 1965 for some engine work including a new Alpha Crank Pin and Bearing as well as a used "H" Camshaft. 1965 Being the last year the bike was registered, it had been in the back of a garage until I pulled it out this March, 2014. 

Attempts to start it were set back with the clutch slipping every time I kicked it over on the compression stroke. Removed the plates and soaked them for a while, reinstalled, adjusted and job done.

After removing the Amal Monobloc 389 Carburetor for cleaning and the installation of a new spark plug and several kicks later, the old bike fired back into life filling the nearby vicinity with plumes of white smoke. After draining the sump and adding fresh oil I was able to go for ride. The motor sounds great, very quiet and smooth with tons of power.

Will be looking forward to riding this over some fire trails in the near future. Until then I will be searching for some Dunlop Trials Universals.....

1960's Howard Grey Motorcycle Photography

I recently came across the website of photographer Howard Grey and wanted to share some of his Motorcycle images from the mid 1960's with my blog readers. Howard Grey's photographic career spans over 50 years in which he specialized in Advertising and Commercial photography. The images seen here were taken for Triumph as promotional material. To me these they take on a different feeling 45 or so years later as the span of time has made them historical images not just. As a restorer of these fine machines striving for correctness in my work there is simply nothing better than seeing factory shots that display how these bikes were assembled. I contacted Mr Grey and he kindly gave permission for me to share some of the images. His website, has a stunning archive of his work and I would encourage you all to have a good browse through it. Prints of his images are available for sale on the website. Thanks to him for allowing the use of these historical shots and full credit is given to him for every image presented here and I must ask that if any of these images are copied that you have the respect to contact Mr Grey for permission. 

These shots above and below are of a 1967 Triumph Bonneville for the Home market.

This shot to me is the most interesting of them all. Alway wandered exactly how Triumph Tank Badges were painted and now I know. The white was sprayed and then the black lettering filled in by brush.

Wheel lacing was another of many tasks undertaken by ladies, a major part of the British workforce since the war.

Below are some shots from the factory in 1966, machines on the assembly line appear to be C Range Tigers (thanks Jon!!). Check out the shelving stocked with new Tanks....

Factory test riders ready for action. This shot also displays the correct placement of the World Speed Record Holder and Made In England Decals adjacent to the Petrol Tank Filler Cap.

Nice shot of a Tiger 100.

The mid to late l960's were the heyday for Triumph Engineering, they were selling tons of machines during this period, most of which came to the United States.

Tiger 100 500cc Twin Cylinder Engines awaiting Chassis' and more machines ready for testing.

Tanks were painted and lined in house.

This image was one of a series for Champion Spark Plugs. Champion at this time were the supplier for Triumph.

Love this shot from the design department. Machine is a Tiger 100.

The images below were slightly earlier, the bike featured is a 1965 Tiger. I doubt they were used for promotion as it appears the rider may be having the same troubles we are still experiencing today!

Again, thanks to Howard Grey for the use of his fantastic images. Cheers!

1951 Triumph Motorcycle Racing Kit Test Report.

1951 Triumph Racing Kit Promotional Advertising piece from 1951, a 4-page brochure that was first published in the November 1951 issue of Cycle Magazine. The front cover displays the kit laid out with a description of parts included.

 $154.00 Sounds like a bargain! The '51 Tiger 100 500cc Twin was put through it's paces with outstanding results.

 Open Megaphones, Rear Set Pegs, Twin Racing Carburetors. Just the ticket!

The close fin Tiger 100 Engine has to be one of Edward Turners finest Triumphs, what a gorgeous power plant.

 120 mph!
