He was born at 351 Ladypool Road, Balsall Heath, Birmingham. His parents, Frank and Bertha, then moved to Wolverhampton where Howard attended Wolverhampton Municipal Grammar School. He was a good swimmer, won swimming medals, rode horses and hunted, and drummed in a band.
He joined AJS as an apprentice, and raced successfully for Sunbeam and AJS, when not plagued with breakdowns. He decided to build his own motorcycle, and in 1924 formed HRD, "Built by a Rider", which only lasted a few years, but built a fine reputation. The name was purchased by Phil Vincent, who then established Vincent-HRD. Howard Raymond Davies died of cancer in January 1973.
Howard briefly worked for Diamond, before he managed to find his way back into Sunbeam. He was then entered for the Senior race at the 1914 Isle of Man TT. He finished in second place, and Sunbeam won the team prize. He did well in other events that year, like the Coventry and Warwick Club trial. Howard won a a gold cup for best performance of the day, and a silver cup for best sidecar performance.
Howard and his family lived at 'Darley Dale', Crowther Road, Wolverhampton at the time.
On the first occasion he found his way back to his own lines, but the second time he and Lieutenant J R Samuel were captured at Karlsruhe becoming prisoners of war.
Initially listed as missing, it was then announced that he had been killed in action. An obituary appeared in May 1917 in 'Motor Cycling',whereupon it emerged that Howard had actually been taken prisoner. He attempted to escape a number of times, once by tunnel, but was unsuccessful.
In 1920 Howard had many competition successes. In July, riding an AJS in the Scottish Six Day trial, Howard won the gold medal at Stile Kop making the fastest time, won another gold medal in the Darlington ACU trial, and broke 14 records at Brooklands, including flying kilometre, flying mile, and average mean speed.
He became involved in T.T. machine development, and by early 1921 the TT machinery was much improved. The 1921 AJS team obtained 1st, 2nd, 3rd, 4th, 6th and 8th places in the Junior Isle of Man TT. The winner was Eric Williams. Howard finished in second place, even after having a puncture in the second lap. Howard finished first in the Senior TT on a 350This was the first time a 350 cc motorcycle won the Senior.
In trials, Howard won the team event, with Harry Harris and Eric Williams in the ACU six day and the gold medal.
On May 24 1921 Howard Davies broke four world records at Brooklands:
Then things returned to "normal". The 1922 and 1923 TTs were a disaster. With the AJS machines suffering engine problems, he did not manage to finish a race. Howard left AJS in 1923 and moved to Hutchinson Tyres.
Davies rode his own motorcycles at the 1925 Isle of Man TT, coming second in the Junior and winning the Senior.
In January 1928, the company went into voluntary liquidation.
He continued to attend TT riders reunions, which started in 1937, and would visit Mallory Park with Albert Clarke. On one of these occasions he got to ride on the track, on an old HD75 and an AJS.
