Canadian Triumph TRWs

[45jim]

Triumph engines were not normally dyno run at the factory prior to installation in the frame. My NOS TRW engine has never been run and it still attached to the storage crate. Like most manufacturers, the m/c was built completely and then broken down for crating as required, not all vehicles were to be crated for shipping. TRW's manufactured for British forces that were to be used in Britian and not added to war reserve were most likely not crated. This would be the vast majority of the TRW production.

A proportion of the manufactured motorcycles were ridden around a test track prior to the installation of chassis dynos in the late sixties. If a m/c was to be crated for export it would most likely have been run as there would be no option to correct faults otherwise. Domestic machines could be repaired under warranty at dealerships.

There are many books written by test riders of English machines as these guys are often the best source of data on rare machines. They kept detailed logs of each bike, the mileage and the type of failure they experienced. From one book I read, it seems that most bikes got a short ride through the gears of less than 10 miles while others were subjected to harsher testing. All of this was done without following the prescribed "break in" regime. Makes you wonder if the break in process was designed to keep RPM's down until the warranty expired.
