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. I have always wanted one and finally bought one in January 2012. Some pictures of it are lower down this page.

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 8:1, modified porting, new camshaft and a larger Amal 289 carburettor.

In 1955 the Triumph T110 changes included: larger main bearings were fitted and a bulge under the timing side case shows if an engine has this. The carburettor was changed to a 1 1/16th bore Amal Monobloc 376 and the Lucas magneto now had a screw in cap.

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. These numbers are in the table below:

Year Pre Unit 500 + 650
1953 32304 to 44821
1954 44822 to 56699
1955 56700 to 70929
1956 70930 to 82797 and after this 0101 to 0944
1957 0945 to 011165
1958 011166 to 020075
1959 020076 to 029633
1960 029634 to 030424

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 56699. My fathers own T110 was delivered new on April 3rd 1954 and was numbered 49xxx and hence must have been built a month or more before this. Having chatted with the marque experts in this area the following needs to be considered.

Triumph calculated its model years not against calendar years (end of December) but against their year end and its summer holiday/close down. Accordingly the numbers above show production to the summer of each year. These numbers are widely circulated on the web, but require a little clarification.

You could have bought a 1954 Triumph T110 in November of 1954 and according to these widely used numbers it would be considered to be outside the 1954 Triumph model year production run even though it was a T110 built and registered in 1954. In addition Triumph tended to show its new models in October of the year and often not start actually shipping them for several months after the show. With all of this considered you could have:

If we then take the summer to summer production numbers and evenly spread them over 12 months, then we arrive at the guesstimated production numbers by month. This is just my best guess and I am sure they would have had a drop in production numbers over Christmas and New Year, but it is an educated guess. The table below shows the numbers from summer 1953 to summer 1954. Using these numbers my father's T110 would have been built around Jan to Feb. 1954, which would seem to roughly fit in with him buying in on April 3rd.

Aug-53 Sep-53 Oct-53 Nov-53 Dec-53 Jan-54 Feb-54 Mar-54 Apr-54 May-54 Jun-54 Jul-54 Aug-54
44,822 45,812 46,802 47,792 48,782 49,772 50,762 51,752 52,742 53,732 54,722 55,712 56,702

Taking the same approach with the following 12 months, the table below would apply. So using these numbers and assumptions the last 1954 specification T110's that were also built in 1954 would have been numbered around 61xxx

Aug-54 Sep-54 Oct-54 Nov-54 Dec-54 Jan-55 Feb-55 Mar-55 Apr-55 May-55 Jun-55 Jul-55 Aug-55
56,699 57,689 58,679 59,668 60,658 61,648 62,638 63,627 64,617 65,607 66,597 67,586 68,576

If any marque experts have more further clarification, then please do contact me and I will update the page. I have had some feedback on my guesstimated numbers above and it would appear that Triumph ramped up production in the new year and spring to have stock to meet the spring/early summer peak of new bike sales. I will have a go at adjusting these numbers to try and reflect this in future. My email is at the bottom of the page.

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.

WANTED - I am looking for the following bits for my 54 T110 restoration:

Set of front forks
Front brake drum and hub - pie crust '54 type
Dual seat with no white pinstripping
Front mudguard
Rear Mudguard
Fuel/Petrol tank

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.


Triumph T110

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 would like a copy of The Triumph 1954 Model Range Brochure then I have now added it to eBay.

If you go to eBay and search for "Triumph 1954 Brochure Speed Twin, Thunderbird, Tiger 100, Tiger 110 & Trophy" you will find it.

So finally after lusting after a T110 for decades, January 5th 2012 was the day I bought one and here it is below. It is a matching numbers bike that was registered in 1954. As a relative novice owner! I know that it is not all original, but it will hopefully be a good starting point to create an original bike in the coming years.

January 18th 2012
I have been tinkering with the bike now have it running more sweatly as the connections from the magneto to the HT leads were loose. The front brake lever pulled back to the bars and the only adjuster on the fork leg had no leeway for adjustment. I removed the cable and removed a few mm of the inner steel core and refitted it and now I had enough free play to use the adjuster. The lights did not work and a quick checked showed that the 6v battery was dry and dead. Not sure how it passed an MoT like this! Sourced a new 6v battery from my local old Triumph shop ( but when I came to fit it today noticed that some of the wires are just twisted together in the battery box area! Nice. I need to get an inline fuse and then I can sort out the wiring around the battery properly. I did rig it up temporarily and the headlights, horn and rear/stop lights all worked - so encouraging. The engine oil looks fresh but the gearbox oil could do with a change and I intend to flush it out before I refill it. I also need to lift the rocker covers as I have oil weeping out between the covers and the head and I cannot see if a gasket is in place.

January 22nd 2012

Went out for a ride on it today having rewired the battery box and changed the gearbox oil beforehand. It started up nicely and off we set for a whole 6ish miles before it started to run very roughly and I pulled over to have a look. The end of the magneto was coming lose and a quick tweak with a borrowed screwdriver and it was back on tight and the bike fired up and ran fine.

By the time I had put my helmet back on the carb was pouring petrol (float stuck) and flooded the engine and it refused to kick start and a bump start was required. I consider this to only count as a single breakdown as it all occured in one location!

It then managed a whole trouble free 5 miles to the pub where I stopped for a celebratory pint. It was dark when I left and happily my lights all worked and the temptation of opening it up on the way home was given into and not sure how fast we went as the speedo has its own ideas about velocity.

I consider it a successful ride (all 13 miles of it!) as I returned home under my own power. Here it is basking in its success in the darkness of the garden.

Triumph T110 1954

January 29th 2012

I have three iron heads with my Triumph T110 and I think may be correct for a 1954 Triumph T110. I have seen pictures of 54's with heads like these but also ones without the little small fin by the exhaust port. I have put some pictures below and would welcome anyone telling me exactly what model they are for?

May 2013

I have been using my T110 again and decided it was time to sort out an oil leak. Oil was weeping from the rocker covers and eventually making its way onto the hot exhausts and then transformed itself into smoke - which looked characterful ... but was less than ideal.

Triumph T110

When I removed the front rocker cover I could see why it was leaking - the previous owner had not bothered to fit a gasket. I had bought a pair in readiness. Sadly I did not get that far. I lifted out the pushrods to check for wear and when I took out the left one, the tappet came with it - well almost all of it. The hammer shaped end did not emerge and the broken part showed a crystalline like fracture. This was not good and despite a mug of tea to hopefully stir up a clever solution, all I could think off was the motor would need to come apart. Subsequent pouring over parts books and if I remove the head and barel, I should be able to get a better look at the problem.


As the bike was running OK before this I am little confused as surely it would not run too well with this broken. Further investigation revealed that no one had ever seen one of these break like this before and I can only assume it is a faulty part. The best explanation I was given was that it probably fractured a while ago but was held together by being under compression from valve spring tensionand it was only when I pulled out the pushrod that the two bits parted - seems to make sense to me. I took off the head and found no damage and all looked good. I then undid the nuts that hold the barrel to the crankcase and then secured the remaining tappets in place with elastic bands and lifted up the barrel an inch or so to have a look. Sitting on top of the cam was the other end of the broken tappet. I fished it out and mated it up to the other end and it was a perfect fit so no bits had escaped into the engine. The two ends had a crysteline look and had not been running broken as otherwise the ends would have rubbed together and marks would show this. I sourced a matched pair of good secondhand T110 tappets from my local shop Rockerbox. I had a thorough look inside the engine and it all looks good inside, the cam had no mark from the tappet. I then carefully refitted the "new" tappets and fitted the barrel back onto the crankcases and refitted the holding nuts and then turned the engine over many times to make sure all was well. With that done I then decoked the piston tops, they look to be standard bore and the bore itself looks good.

The valves roughly cleaned up before grinding them in.

The inside of the head is marked with - E3925

Anyone know what this indicates?

Next up was removing all the valves and decoking and cleaning the head and then grinding in all the valves with grinding paste. Clean it all thoroughly and reassemble. It all went back together easily and then it was just a matter of setting the valve clearances and putting the rest of it back together. After a few hours we were done and it was wheeled outside to see if it would start. It started first kick and sounded very sweet. The original petrol pipe has gone very hard so I fitted new pipes and clips and we were 100% petrol tight. The dog had been "helping" me in the garage and I thought he was being a bit quiet - the little hairy git had eaten and chewed up two of the thick rubber washers that sit under the tank mountings.

I took it out for a 10 mile test run and I think it is now going better than ever, with valves ground in and clearances all spot on it seems very frisky. Back from the test run and adjust both brakes and the clutch and back out for another 10 miles trip. It was sunny so my test turned into a 70 mile ride - bike going very nicely.

Another sunny day so out for a 80 mile ride to nowhere imparticular, just out enjoying riding the bike.

Went out for a 40 mile scamper today and having properly adjusted the clutch, we can use full power with any slippage. The speedo has a mind of its own so not sure how fast, but I am sure we were topping 70 in places. Having never ridden one of these in tip top condition I am not sure if it is running perfectly or not - it seems to go very well. If I can stop riding it then I think its time to check the timing of the magneto and see if that is spot on. The Triumph maintenance manual and the Haynes one have different figures for the timing, so further investigation required.

After the last ride I sat outside next to the T110 with a mug of tea and just appreciated it - it is a fine looking machine.
