I just got the new side panels installed on our 2013 ST-S. I had the dealer do the work. The ride home was about 20 minutes. When I got home, the left side was still too hot to touch with my bare hand. I put my infrared heat gun on it and it showed as high as 162 degrees on part of the body work. Unfortunately, I never took a reading with the old panels so I can't compare.
It was 103 air temp yesterday when I rode home so a typical July day in AZ. I didn't feel the hot panel while riding because my leg sticks out a little while riding, but my wife is the primary rider so I don't know if this is going to be any improvement at all for her, since her knees rest against the bodywork. She doesn't ride in the hot weather anyway so we'll see later on in the year. If it doesn't work for her, I guess we sell and find something else.
BRP did not pay for this, I paid. The panels were 667 plus tax, install was 66 at the dealer. The panels were just two part numbers, it is listed as AIR SCOOP RETROFIT KIT. The part numbers are 219800343 and ...344 for the circuit yellow panels, 4 body parts and some other items.
I'm going to complain to BRP, knowing I'll just get the usual corporate run around, but I'll get it off my chest and move on. If the wife doesn't like it when she starts riding again, we'll just move on. Life is short, we probably don't have many riding years left so I won't be losing sleep over this.
Glad it is working out for others.
