Where do you think that the hot air is coming from? Also, have you ever seen or heard the fans come on?
I think your fan is coming on and you may not actually hear it, just feel the hot air from it.

I am still learning in a parking lot and when the fan comes on, it is hard to hear, but I do feel the hot air on my legs.
Heyy guys! I am facing the similar issue with my bike. after a ride of about 10-12 kms i start feeling hot air on my legs and it wasnt there when i first bought this bike. I think this hot air is coming out of radiator fan. the honda service center says this is normal. But I know this is not normal. if anybody can suggest anything it would be great!


thanks in advance
How many bars on the temperature gauge? If it's three, then your bike is not overheating.

The radiator is on the front of the engine and the hot air has to go somewhere. I could see a problem if you're riding in shorts (actually, I see a lot of problems with that, but they're your legs and not mine). I've never had a problem with my bike, even in 100-degrees (F) , but I always wear gear.

If your legs are exposed, then a rear-engine mount may be a better choice than a standard.

Thanks for your input! the temperature gauge shows it normal. its not more than three. However, the bike never emitted hot air towards my legs before.

Sometimes honda service people says that the fan wasn't working and we have got it working now. But the problem doesn't go away.
If the temperature gauge shows three bars then everything IS working and there is no problem. Engines give off heat, fans blow hot air. There is no problem.
I felt lot of heat blowing from the radiator with my run-in oil or oil inside bike from factory..
This happened with 5-10km rides

I felt it reducing the heat after first oil+filter change..and experienced such heat blow only after slow moving in traffic in low gears for around
10-20minuites

after the 4rth oil+filter change,i couldnt even feel heat blowing off radiator,in short rides

sometimes when slowly moving for 20minuites,when fan comes up,i feel heat,and when bike picks up pace,it goes away fast.

Gain some miles on it.
Ride safe

My bike feels hot at times too. But that is after a solid 3hr+ hwy run at speeds of 140kph and 7-8.5k rpm. Never seen the temp gauge go over 3 bars and never felt or heard the fan. I assume it must have come on a few times while in traffic this past summer. Almost time for my 4th oil change. Put on close to 4000km since end of August which seems reasonable until you know that i only ride the bike on Sat and Sun. I got the bike new on Oct 14 2011. I will probably be at over 15000km after the upcoming weekend.
