In 1933, Gunnar Barthelsson proved himself as a competent rider when he ousted the competition by winning at Solvalla. He led both his heats on the ultra-fast 700cc Husqvarna machine. Barthelsson had an average speed of 108 km/h, and his winning time was two minutes 46.6 seconds. A year later it was time for another Solvalla experience, again in the famous autumn event at the Stockholm horse-race track. Gunnar Barthelsson again raced with the 700cc Husqvarna engine, which proved to be faster than the machines of his competitors. Not only was Barthelsson fastest during practice, but he also set a new lap record during the first moto at 2 minutes 44.1 seconds after 5,000 meters of racing. This spring event was again well visited from motoring fans. Again, the crowd was estimated at 15,000 spectators. In the final, Husqvarna-mounted Martin Strömberg flew away from the start, going sideways into the first corner. “I was lying as close to the inner edge as I could when I heard the big-bore 700-engine coming up on my outside. Trying to avoid being overtaken was certainly in vain,” said Strömberg. “Gunnar Barthelsson seemed to be born on this heavy machine and there was no way anyone could follow in his tracks”. Barthelsson won the final leg and became the big champion of the day.
The 1934 Swedish TT race was run in Hedemora on the 27th of May. All the celebrities were present, and a huge crowd promised a successful and exciting race day. The 7,265-kilometre track around the Dalecarlia province was run going in the left direction after the start. A mere 500 meters had tarmac while the rest of the circuit consisted of a slippery, gravel road. On Friday’s practice day it was evident that the Husqvarna of Gunnar Barthelsson proved to suit this track very well. On top of it, Barthelsson was a first-class rider, so everyone knew he would be a man to count on for the Sunday races. Barthelsson used the Gunnar Kalén Saxtorp machine from 1932, but the two-year old bike proved to still be up to standards and was more than competitive here at Hedemora.
