Was on a trip out west and stopped by their shop and had it installed. Guy I was with had done a review for Thunder Press on it so I figure what the hell. I don't have an oil temp gauge but other guy does and he said that it dropped it almost 50*.
Results are IDK the actual temp difference but I can tell you that my right leg temp meter has been reduced by 1/2. Didn't realize till I did a parade ride for an hour,90*,riding at, well parade speeds, and my leg wasn't burning up at all.
Cool way it mounts, under bike between the rails. Material is top of the line aircraft quality, that's what his main buissness is I waited an month to post this as I wasn't sure how it was working because of not having a temp gauge. I am a believer.
