Running hot

I've had my Supersport S for some three weeks now. It's my first water cooled and fairing equipped bike and I'm a bit concerned about how hot it gets. Really hot in slow traffic. Nice in cool weather but less so at near 30 degrees celsius (86 F). The instrument is showing 106 degrees Celsius (roughly 223 degrees Fahrenheit) before the fans kick in. That ought to be near or at the boiling point for the water/coolant mixture. Is that normal?

Sounds normal to me (I've owned several water-cooled Ducatis). I've ridden a couple of demo Supersports and noticed some heat coming from the rear cylinder, but not a problematic amount IMO. Motorcycle-specific clothing might help (leather or mesh pants).

That's a normal temp for a fan to kick on, at least in my Japanese bikes.

My CBR can get to around 230 on a really hot day in traffic, and I start to keep a close eye if it gets to the mid 230s. If it ever got to the 240s then I'd shut the bike off, because my cousin's CBR got to 250+ once and it caused damage to his head gasket. By 240 I'd take a look at the cooling system.

What is the boiling point of water when it is mixed with anti freeze and then put under pressure? It will be much higher than 106c!

106C is exactly what it should be. When i got my bike we put it through a series of switch on and warm ups which the dealers (should) do. This sets the blah blah and makes it Blah blah blah... i think i may have stopped listening at some point because, well, my bike, engine running and my just a little bit eager to get onto it!>

I'm sure some old fart on here knows exactly what this sets up...0

Leather pants certainly help. I had a similar problem with the Panigale and now the same with the SS. Leathers really do help to prevent you cooking your legs:wink2:

Having a tall first gear doesn't help when you're in traffic. I try to avoid traffic areas on the SS just for the reason. I always ride with motorcycle specific pants. Check out Diamond gusset defender jeans they do a great job keeping the boys from getting cooked.

Obviously different depending on quality of glycols but think 260C is what I seen on some bottles.
