Just back from an overnight ride/camp. After unloading gear (~ about 7 - 8 minutes) I remembered this post and touched the final drive- hot! Got my heat gun and here's what I found:
- 130F rear brake caliper and final drive
- Moving up the swing arm it got hotter and hotter - finally 180
- The starter was 224
- Most of the exhaust was 300ish to 335
- The heat shield protecting the tire was 220- I added a layer of Heat Wrap material between there a while back, as the Exedra Max is closer to the shield and glad that I did
- Sorry, I didn't think to measure the seat, but under the seat I know it gets very hot.
Keep in mind that this is all nearly 10 minutes after shutting off the bike.
I think it's the cat box that's responsible for this. The big question, that someone else has asked is, how these temps differ with those running aftermarket exhaust minus the cat box? I had the Werkes pipes, but couldn't take the noise on long distance rides, but interested to see the difference.
If I could find something less loud without the cat box I would definitely consider going that route, although with more free flowing exhaust I think you lose some torque, which is what I value most, not HP.
This can't be good for anything that is heated up more than necessary for long periods of time.
