Triumph 1926 Model P 494 cc side valve single frame# 93 8217 engine# 233183 CSA
In the twenties Triumph had to fight hard for their market share.
Their answer to the competitors was a basic 500cc bike: it was very was cheap – £42.17s.6d -the type SD, also a 500 cc side valve single, was £83.00. By using new mass production methods labour costs were cut.
There were some teething troubles with engine and clutch quality in the early series; when these problems were solved the design turned out to be very practical. More than 20,000 Model Ps were sold. Compression ratio is 4.1 to 1, top speed about 54 mph.
This machine is equipped with Bosch magneto and steering damper and has been finely restored.
