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  combination is a matured restoration.
