Triumph TRW 500cc Military
We have made this brief history page as there is currently very little information on the internet about the Triumph TRW. We also have a wide range of spares for these bikes, for example, complete engines/gearboxes.
The Triumph TRW was designed in 1943, but by the time the bike was finished, the war was over and the military had a surplus of bikes left over. In 1948 the TRW was released in it’s final form and were sold to the British Army as well as other branches of the military, at home and abroad. This continued until the 1960s.
The 500cc side valve engines were used with many of the commercial productions machines in order to keep costs low.
MK1 BTH Magneto Model
MK2 BTH Magneto Model
MK2B DKX2 Distributor, 1 ignition coil
MK3 Contact Breaker, twin Coil Ignition
The TRW was used by various countries for Military purposes around the world, including; Canada, Pakistan, Holland, Germany, South Africa…
Classic Motorcycle January 1994: “In a production run from 1950 to 1964 Triumph turned out 15,939 machines. Some reached other arms of the British services, but the vast majority were exported.”
Burton Bike Bits now have a very large range of parts and spares for TRW models. See below or search our catalogue using part numbers.
