I don't have soft lowers but have hard lowers. I know around the end of May , they come off and me and the bike cool off.
The soft lowers dont look as aerodynamic as hard lowers , so that might affect the engine also in the hot weather.
I do miss the advantages that the lowers provide , but I can't take the extra heat down here in Ga. In the summer.
