1975 Triumph 4 Cylinder 1000cc
With the final version of the Trident,the T160,
in production the Experimental Department under
Doug Hele and based at Kitts Green, looked ahead
for a successor and built this interesting four
cyclinder prototype which just had to be nicknamed
The crankcase was made by machining two triple
cases and then welding them together before
the final machining was done. The cylinder block,
the head and camboxes were all produced in the
same way but the crankshaft was built up and
the camshafts specially made and carried cams
with mild timing. Most other parts were from
the triple or twin suitably modified where necessary.
It pulled a top gear of 4.2 to 1 and ran nearly
125 mph with the mild cams.
Only one was made but as a piece of ingenious
and highly skilled engineering, it would be
hard to beat.
