1954 Triumph T110 Engine


This is the power plant destined to go into the rigid Triumph project, from the first year of the HOT 650 option, it's a '54 Tiggy Ton Ten. Stripped it yesterday for a clean and a look inside, no major shocks in there and a pleasant surprise that was a bonus. The crank and rods are all in good order as are the bores and pistons on +0.020", so all OK there, the result being that it is fitted with a E3134 cam on the inlet and "R" followers on both sides, all in fine fettle.
There is a snapped top fin on the barrels but luckily the broken off piece came with it, so it's over to Chip's this morning to have that brazed back into position.

Here is what the National Motorcycle Museum has to say about the '54 Ton Ten;




About the 1954 650cc Triumph Tiger 110
Ton-plus Tiger

When released for 1954, Triumph’s Tiger 110 was among an elite of a few 100mph-plus vehicles available to the general public. But although the 110 was truly a snarling tiger when the throttle was opened, it could also be a docile kitten when riding around town with the ignition lever set to retard.

While derived from the 1950 Triumph Thunderbird, the fast and sleek T110 incorporated significant advances over Triumph’s first 650cc twin. Engine tuning included a revised cylinder head, bigger carburettor and an inlet camshaft developed for racing. It resulted in a healthy 42 horsepower, dealt with by strengthening of the crankshaft and its main bearings. The T110’s frame is Triumph’s new swinging arm type and an up rated front brake featured an air cooling scoop to help prevent’ fadeif the drum was applied repeatedly, as it would be when travelling fast over challenging roads. An attractive Shell Blue Sheen colour scheme was shared with the 1954 500cc Tiger 100. Following a Triumph tradition begun with pre-war Tigers, the 110 model code hinted at top speed, which was not far short of 110mph in standard trim. A startling 117.2mph was recorded in 1954 by the weekly Motor Cycling, but that was with a press test machine, tweaked, by factory staff.

  1. Nice one Brian, it's great to see more rigid Triumph's getting the treatment they deserve! Perhaps when done we should do a photoshoot with the two of them together.
