That's because it's simply not necessary ....I know for a fact that the factory do not do this.I have done about 20 Hondas and haven't had a failure as yet
Bike is finished! without heat treating!!!
In Germany all tracks are closed yet, because the winters are cold and full of snow.
There will be enough time for the aluminum to stress out alone, without a heat treating furnace.
In 3 month (february/march) we will check up the strongness of the frame of jumping some big jumps.
The 2 honda CR 500 AF builds my kollege has done before, also never had seen a heat treat furnace and were finished also before the winter
