Too Hot For Motorcycles?

Personal discomfort aside, is 35c+ really bad for the bike itself? A fellow blew a rad hose right beside me a few days ago in the heat. I don't want to do any long term damage as the oil must be really thin in these temps....
 
the motorcycle will be fine in these temperatures. thats what oil, fans and coolant are for.
 
If you're bike is liquid cooled, no. Air-cooled bikes can get bogged down sitting in traffic and old beat up transmissions can get sticky gears due to heat expansion.
 
Bike will be fine if it's in proper working order.

It's parking that can be risky. I could see the kickstand slowly going into the pavement, it would have been on it's side in another 15 minutes.

People ride regularly in Arizona. The Paris-Dakar goes through some interesting desert and most bikes survive.

If it's liquid cooled you shouldn't have a problem. If it's air cooled you may need to watch if you're stuck in traffic and consider pulling out and shutting down for a bit although I've never had to do so and used to ride an air cooled six cylinder in heavy traffic in Toronto summers with no problems.

Keep in mind that the engine running temperature is a lot hotter than the ambiant air temp. As an example, my liquid cooled bike runs at about 80 C on a cool day (ambiant 15C) and 102 C on a hot day. My bike's engine temperature is more affected by whether I'm stuck in traffic then it is by the ambiant temperature.

These are my own experiential observation and I defer to those of more mechanical knowledge....

If it's +35C and I'm taking the bike out on country roads with no traffic ... she runs just fine with no complaints.
Now, duck-waddling the bike downtown in stop-n-go gridlock with little air flowing through the rad or cooling fins, that's another tale.
 
air cooled, and never a problem... unless your stopped for a long time in traffic. Took about 30 mins of waddling through traffic before I was just below the overhear line. Once moving again, within 15 mins or so the bike temp level returned to normal.

I wouldn't want to do that in this weather for my own sake, concerns about the bike aside, and while wearing all your gear?? Though I'm sure a lot of people go squid on extremely hot days.
 
You will die before your bike in the heat, also it gets way hotter than 35 C in the oil pan and radiator anyways, so what's the difference?

I know have been. been soo hot. Throw in the fact that I'm sitting on top of an engine that is running at over 100 degrees celcius. no way I'm wearing my jacket too! f that.

However, if i was going for a longer or highway ride, i would wear a jacket, though just a mesh one.
 
Heat won't hurt and watercooled bikes - my temp gauge never moves once running but dehydration is a real risk - kills your concentration etc.
 
Wet your T shirt with cold water under your gear, open all your vents. Voila! On Bike Air Conditioning ;)

Can you provide a video of the process from scratch?

Psh. I just ball out. Today I wore a black suit, black shirt, black helmet and a tie. You should have seen the face on the cop as i blew past on my nekked ninja 250... doing the speed limit ...in a school zone. bike was screaming in 2nd gear.
