Triumph T110


The Triumph T110 or Triumph Tiger 110 was released in 1954 and was one of the fastest motorcycles you could buy.

My father had bought a Triumph Thunderbird 650 new in 1950 and on April 3rd 1954 he took delivery of a new 1954 Triumph Tiger T110. It is pictured below.

I think the first Triumph T110's are some of the nicest looking bikes that Triumph ever made.

The Triumph T110 or Triumph Tiger 110 was named "110" due to its claimed top speed. Whilst the factory (tweaked) test bikes were recorded at up to 117mph, a normal bike would may have just topped 110 mph. The Triumph T110 or Triumph Tiger 110 was produced in a beautiful shade of a light metallic shell blue, it really stood out from the rather drab and dull colours of most bikes of the era. The Triumph Tiger 110 had a 649cc engine a claimed 42hp at 6,500rpm.

The Triumph T110 was first seen at the Paris salon in October 1953 and was the first Triumph to feature swinging arm rear suspension. It was the sports version of the Triumph Thunderbird. The Triumph Tiger 110 came with a higher compression ratio of 8.5:1, modified porting, new camshaft and a larger Amal 1 1/8th bore 289 carburettor. A larger timing side main bearing (E1591) was fitted to match the drive side and a bulge under the timing side case shows if an engine has this. The rest of the range save the Speed Twin also benefited from this main bearing improvement.

In 1955 the Triumph T110 changes included: The carburettor was changed to a 1 1/16th bore Amal Monobloc 376 and the Lucas magneto now had a screw on cap. The rear brake plate and swing arm were modified which allowed a torque rod to be used in place of the peg and slotted swing arm of the first year.

1956 the Triumph T110 gained a new light alloy head with a higher 8.5:1 compression ratio.

1957 The tank badge was redesigned and a two tone colour scheme became available as an optional extra. Standard colour was now silver-grey or the optional ivory on blue for the tank with ivory mudguards with a light blue centre stripe that was gold lined.

1958 The slickshift gear change was added and allowed clutch less changes, although it was not that popular seemingly as many owners found that it gave quite a jerky gear change so continued to use the clutch lever as usual. Deeper front mudguards were now fitted and the existing 8 inch front brake now took up the full width of the hub and a steering lock now came as standard. A new twin port alloy head was also available in this year to allow twin carbs and to stand up to the extra performance the crank was now a one piece unit. You could now also get your T110 in an optional colour scheme of black on ivory.

The bikes left the factory with matching numbers on the frame and engine and these can be used to date the bike as the numbers ran in sequence. However the numbers that are scattered around the web and in a few books, purport to show bike serial numbers and year produced can be a little misleading. I have been assisted by those in the know and the table below probably gives the most accurate view of numbers by year:

Year Engine/Frame #'s
1953 32302 to 44821
1954 44822 to 55493
1955 55494 to 70929
1956 70930 to 82797 then 0101 to 0943
1957 0944 to 011113
1958 011114 to 020075
1959 020076 to 029363
1960 029364 to 030419 then D101 to D7711
1961 D7727 to D15754
1962 D15789 to D20308 

I have looked at several 1954 registered Triumph T110's that have numbers several thousand digits past the supposed cut off for 1954 bikes which is 55493. My fathers own T110 was bought new on April 3rd 1954. Normally bikes were assembled on the main line within a few days of the engine being made on the engine line. The bikes were tested and if passed were shipped within days of manufacture. My fathers T110 from the factory records - The engine was built wednesday 27th Jan 1954 with no mention of any special specifications The bike was assembled friday 29th Jan 1954 in the forth batch for that production year. I was one of 500 in that batch. It was dispatched from the factory on tuesday 2nd february 1954 to the dealer that sold it to my father.

November 2012, some further info kindly supplied by a reader - The first T110 was numbered 47038. The 53rd T110 produced was made in November 1953 and was 47116 - it still exists. So it would seem that T110 production started at the earliest in October 1953 and probably in November 1953. If the literature (below) was issued on 31st October 1953 and the bike changed slightly after that, then perhaps the first bikes rolled out in November 1953 as supported by the manufacturing date of T110 # 47116.

The colour pictures (below) were taken from Triumph literature that was issued on 31st October 1953. You can see that a few things (such as the front brake) changed before the bike was first sold. In the literature below they are referring to the bike as a Triumph Tiger 110, though my father and others just seem to call them a Triumph T110. The Triumph Tiger 100 was the 500cc model.

Fact or Fiction? The following are things I have read about T110's that seem to contradict, so suggestions are welcome on which is correct:
Triumph moved away from Iron heads due to iron heads overheating and/or it was more fashionable to have an alloy head?
Early iron head T110's are both descibed as faster and slower than later alloy head versions?

So how reliable was a new T110 and what maintenance was required? My father had worked in his Dads motorcycle shop before WW2 and then worked as an engineer in the RAF, maintaining and rebuilding Merlins during the Battle of Britain - so he was a very well trained engineer and mechanic. He kept detailed logs of all his bikes and I have summarised the one for his 1954 T110 below.

When the engine blew up Triumph were at first reluctant to acknowledge a fault. My father had access to state of the art engineering facilities and had the gudgeon pins analysed as they had failed. The technical report showed that they had not been hardened properly and hence failed. Presented with this report Triumph then took the engine back and repaired it.

This is the cover of the literature. It features the 650 Thunderbird even though the Triumph Tiger 110 is now the top model in the range.

The literature below is from the same document. My father covered almost 100,000 miles in 10 years on three new Triumphs (46 Speed Twin, 50 Thunderbird and Triumph Tiger 110) and where they say below "complete reliability" they should perhaps have said 10-20,000 miles of reliability and then a few issues might come up. My father recorded every mile of all these bikes so every item of maintenance and failure is recorded.

If you like bikes of this era then you should like another web page I have created. It is the story of my fathers 1953 trip around Europe on a 1950 Triumph 650 Thunderbird with his pals on a Brough Superior SS100, Triumph Tiger 100 and a couple of Sunbeams. It contains many beautiful period photographs:

The following pics were kindly sent from David in New Zealand who owned it in the early 60's. It has the same black only seat without any white piping just like my fathers one - so maybe the early T110's were like this.
