How Hot Is Too Hot? - 14R

Today I rode a little stretch on the interstate. I had been moving at 80-85 MPH for 30 miles when I hit the exit ramp, and I ended up waiting in line there for about 5-7 minutes. While I was sitting on the ramp the bikes coolant temp climbed as high as 214 degrees. Traffic finally started moving about the time the bike got to 214, so I'm not sure how much higher it might have gone.

The outside air temperature was only 86 at the time. Should the bike have gotten so hot? I'm a little worried about how the bike will act when the weather goes up to 95 or 100 degrees later this season.

Sorry if this seems like a dumb question, but the 14R is the first vehicle I've owned that gave the coolant temp with degrees rather than just a needle gauge. I'm not sure what the safe temperature limit is for the engine.

Thanks

Edit: The bike has no performance mods of any sort. Stock exhaust and all. About 2500 miles.

I've seen 208 on mine in similar temps and wait times. I'm not very concerned about it.

+1. The 2nd fan kicks in just over 200 on mine - it seems to cool better than my old 2006 '14. I wouldn't worry unless it goes over 230.

Don't sweat it ... As long as it goes back down as you get moving you are ok ... Newer cars run 210 to 220 ... Heat = HP and MPG .. It will run cooler once you replace the dog rocket exhaust with a good 4 into one exhaust ..

I added a relay & put a manual switch on my fan... Riding in NY can be a pain, especially when you hit traffic...

I replaced my coolant with lp coolant. It was the only one my local stealership had in stock at the time. It seems to help a bit. My temps usually stay.in lower 200s while stopped.

I was really impressed at these temps. Even in stopped traffic. Actually the coolest running bike I've ever had and ironically highest horepower. My old 14 used to peg outa sight in stopped traffic & this is a huge improvement.

Thanks for the info, guys. I didn't realize the temp could go up so high (above 212) and be alright. I rarely get stuck in traffic, so hopefully I'll never have a real problem with heat.

I'm scheduled for a track day at Barber this fall, so I'll probably change to Water Wetter for that anyway. Maybe that will take some load off the fans.

Understand that the 14R cooling system operates at a pressure approaching 18psi. That changes the boiling point of pure H20 above 212F. Add to that you have an ethylene glycol based coolant in your scoot. At atmospheric pressure its boiling point is well above 212F... add to that 18psi... boiling point goes even higher.

So far, the all-time record high in Chattanooga is 106.

Maybe I'll take the bike out this weekend and see what happens with the temp in this weather...

105+ multiple days in a row in DFW and 100% at 10pm. Rode it fairly hard last night and saw 200 a couple of times at lights but can't tell you how impressed with how well this big bike cools itself!

You were sitting at a traffic light for 5 minutes or more and it got to 214 ? Completely normal.

You have absolutely nothing to worry about...I'm surprised it didn't go higher...A lot of bikes will go higher in shorter amounts of time... I had an RC 51 and it would go up to 220 in much less amount of time even in cooler weather of course that's when I would shut it off....

That's a clear signal that the 14r has a very good cooling system.

Thanks, guys. I'll take her out for a little while on Saturday. If she can handle the high of 108, I'll never worry again.

if youre really worried bout it drain and fill it with some engine ice, it was one of the first few things i did when i bought the bike.

Not really worried about it, just didn't know what a safe temp range would be. This bike is the first vehicle I've owned that gives the temp in a digital read-out instead of just a needle between hot and cold.

It's 104 outside right now... Probably will take a ride in a little bit. Good times.

So I took the bike out this afternoon. The outside air temp was 107 when I got home. I let the bike idle in the driveway for a little while after the ride, but even in that heat the coolant temp only got up to 219.

I am impressed.
