Highest temps you've ridden moto in?

107 on the truck radio leaving Horn Rapids today. Prior high for me was 104 in Boise years ago. Wasn’t terrible but I wore out quickly and even being in motion didn’t provide relief.

I’ve done GH several times when over 100 without issue, but that’s nothing compared to the humidity back east. I did LL’s in 2015. One of my Moto’s was around 2:00 o’clock one day. I don’t remember the exact heat and humidity, but it was mid 90’s for both. I do remember the heat index though, and that was 116. It didn’t feel too bad during the moto, until I tangled with another guy and we both went down with like 2 laps to go. I picked up by bike and started kicking. At that moment, with the adrenaline and lack of airflow, it felt like the heat literally jumped on me. After the moto, I pulled over to grab my son. As soon as I stopped, and there was no air flow, the heat felt oppressive. He asked if I wanted water, but all I wanted was to keep the air flowing over me, so I told him “I’ll just meet you back at the motor home.” Before I could finish my sentence, my YZ coughed and stalled. I started kicking, but 3-4 kicks in, I couldn’t take it anymore and just started pulling my gear off right there in the spectator area and pouring water over my head. I’d never felt heat like that before or since. My son grabbed my bike and tried to get it relit, but that too was a chore because I think the fuel was boiling and it was vapor locking. The moral of the story, heat is one thing, heat and humidity is something else. Be safe. 👍

Carlsbad, well over 100, dead still air, 35 minute motos sucking dust in the baking sun.
I had one of those fox cold pack vests that had pockets you filled with ice.

Red bud the year Josh Lichtle passed away from heat stroke. 2011. Africa hot that day. Pulled off for I was hallucinating. RIP brother

106 yesterday…did two 20’s and a 30…my kids rode the whole time with a few short breaks

Raced offroad a few times by 110. I joined Team Fried.

I still have one very precise memory (after maybe ten years) of a dry river bed, littered with rocks and agonizing riders, that went on for miles. I thought I'd never see the end of it.

Yep, I've raced a few times at Glen Helen in 110+, it's not that bad with the dry heat. Just watching the National at Budd's in 2019 felt much worse.

Yes

Florida in the summer…

I’m the exact opposite.

I rode with one your buddies from back in the day that lives in Covington/Maple Valley, Washington yesterday. We rode twice on the hare scramble course and all of us were struggling! I almost over heated after the first one. It got up over 100.

Best ( or worst) I could do for a full on race would be 107 at GH. No easy-up and only a beach umbrella, so I ended up trying to survive by crawling under the truck.

Worst motorcycle experience was in SE Asia: I borrowed a DP bike and went for a cruise. It was 45C/114F with 98% humidity. I thought things would improve if I opened the shield on the helmet, but that was just a blast furnace. On the other hand, life just goes on for people in those conditions - looking out the window of our A/C equipped SUV, you'd never know it was that hot.

I'm surprised there isn't a bunch of Aussies chiming in on this. I was in Perth, WA back in the late 90's when the O-zone hole regularly made the news. It was 45C - just a couple minutes outside and it felt like the sun's energy was eating into your skin.

Lots of cold stories in Canada: Numb Bum 24hr for one. And I've always tried to ride my MB to the office all year round, although it gets a little tough at -35 with snow...

120+ at Chuckwalla, had to do a 6th gear cruise lap to help cool off the bike before pulling into the pits or it would over heat. 117 at Adams supermoto, that day was rough being in a leather suit. Too many 105+ mx days over the years.

My avatar was at Sunrise (Racetown 395) raceway in July or August of 92, it was 113 at the 1:00 start of that race. I was working construction and young, couldn’t do anything like that today.

Hell’s half acre

desert raced in the early 80's. We did european scrambles that lasted 1 hour. I used to bury my feet under the sand until just before the banner went up. We did not have camel baks back then. Would not put that kind of stress on my body like that ever again. I would rather choose the mountains or the beach .

100+ many times in Texas, Ponca, Las Vegas, Lorettas.

Agreed. I hate doing anything but skiing in the cold.

I drove by Glen Helen today on my way home from the high dez.. truck thermometer read 110...

105 degrees, never again.

I can tolerate heat ok but once it hits triple digits, I’m out. Not worth it.

A lot of 90,s humid , if the dew point is above 65 preferred higher . The hotter and more humid it is, the more I like it. Bring 10 gal of fuel, 3 quarts of trans oil, 5 gallons of water. No ice in the water, ice water turns your stomach into a knot. Track was hard pack gnarly square holes,with sx whoops. If the 3 vet riders where on break in the shade, I would rip the whoops for 15 min back and forth. I never sleep with the ac on, I get muscle cramps bad from ac. Last week out west it was 104 it’s hot, but not uncomfortable. I,m not used to the dry heat, I drank a lot of water for 2 days.

Budds 2019 was seriously brutal. I bought an umbrella from the pits just for some shade it was that damn hot.

Born and raised in Iowa, never once rode/raced in 100 degree heat. But definitely some days around 90 and very humid.
Just over 23 years in Texas and I can easily say I've rode 100's of times in temps of over 100 and high humidity as well.
So far this year North Texas hasn't officially broke 100 air temp, (99 twice though so far) but I rode just 2 weekends ago when the heat index was 105 at Oak Hill.
Highest temp I've rode in here was probably 109 air temp. Highest heat index I've rode here was probably 113.
I've come in the pits many times, goggles already off, put bike on the stand, and immediately the helmet, gloves, jersey, come off, and I pour lots of cold water on my body. If it seems I'm not cooling down enough, I've taken my boots off, pulled the pants down and laid in the back of the truck or gotten into the truck, turned on the A/C and with the vents blowing full blast, sat in there for 15 minutes or so, until I was ready to go another 20 min on the bike.
One thing that has helped me is that I spend so much time outside in the heat (which lasts at least 4 months here) that I do believe I get acclimated to it somewhat.

I can't say with any accuracy how high the temps were in some of the races I rode in when I was a much, much younger man down in Texas, and the surrounding states...but even at that age, when I was in worlds better shape...many times it was absolutely brutal. There is nothing "kind" about a Texas Summer. But, when you're young...you recoup quickly after a moto, and shake it off. I loved it no matter the heat!

Today...I wouldn't make a lap in those conditions without having to pull over. Ha!

Do motors boil coolant any faster when its 100 versus say, 85?

Yes sir, the way the trees would keep the air stagnant it was hot and muggy!

Probably back in 1980 July 4th weekend. The temps were in the high 90's and God knows what the humidity level was. If memory serves, I did the first moto, and probably got a little smoked, but I was young and invincible so I thought nothing of it, and went out and did the second moto.

The guy who was pitted next to us said I rolled in from the second moto and just fell over. Next thing I remembered was him splashing water on my face. He'd propped me up against a pine tree and was trying to cool me off. This was back in the days of cotton jerseys and hybrid leather pants, so no heat was escaping my body with all of that sh*t on, plus, a JT chest pro, and Scott boots.

We were real men back then, so we didn't seek medical attention just because someone got, "hot". We just drank a glass of milk and went about our business...actually, we were idiots. I'm sure at the very least I had heat exhaustion, and possibly low-level heat stroke.

I raced a sprint enduro last summer that was triple digits. Got smoked by Andrew Short.
The waiting between tests was the brutal part. The riding wasn’t bad.

Mid 80, had a Malcolm Smith Sponsor ship managed by Kinny Jones and was invited to the Riverside GP. Being from the Seattle area, I was not prepared for the heat! Really no idea on the temp however I know it was well over 100. I was up on the hill above the pits when it all went crazy. I knew I was in trouble. Rode to the motorhome and leaned my bike against it (something I never do) and fell to the ground. Asked and got wet towels! Quite an experience knowing that the body was shutting down.......

Riding Lake Havasu in August 115+.

Stayed closed to the lake and jumped in with my gear on. Stupid and young.
