NEWEST BUILD UNDERWAY…1957 TRIUMPH TRW 500

Apr 14, 2026

The 1957 Triumph TRW500 was used by the British Army as a matter of course , not just in times of war.
Triumph designed and built the TRW in a couple of years after WWII end.
They demanded a bike that could cross in 15 inches of water and was inaudible at a half mile range , a TRW side valve vertical twin was one of those machines .
A modified and updated version of the bike was selected for postwar use beginning in 1948 and ending in 1964 , many saw service with the armed forces of many Commonwealth countries as well as with NATO forces, many purchased by the Canadian military.
By 1970 many were declared surplus and sold off to the private sector, and it was fairly common in the 60’s and 70’s to see these both assembled and still in a crate being offered for sale for three to four hundred dollars .
We’ve decided to take a bit of a departure from the drab institutional military green that they first appeared in and go for something a bit different, something a bit more laid back , something to break the mold after all of the adherence to stock restorations.
This laid back personal touch is a valued and integral part of what owning and riding a motorcycle is all about.

Adorned with a blue metal flake fiberglass body, this thing oozes 70’s cool, ready to power over Baja sand, or Ogden snow. 

 

An 8hp Tecumseh powers the CVT, we installed a smaller belt to allow for maximum power output. Independent rear disc brakes allow you to hit some tight corners, though the lack of a roll cage may make you rethink. 

The elusive Ski attachement we are searching for so we can really test our might in the winter.

If we do not locate an original, we will get it up on the bench and fabricate one, as we are gluttons for punishment.
