Triumph 1926 Model P 494 cc side valve single



frame # 943004 engine# 243443 ESA

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   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  was first registered on May 17, 1926    and was owned for many years by a Mr. Alex Fanning, a gamekeeper on an estate near Kingussie, a small town in the Highland region of Scotland. 
It was sold to a Scottish motor museum in 1972 and has since been restored.
