This data, as far as i can tell, applies for ALL years of the Honda 600RR

for imperial measurement (U.S.)

the temp gauge starts reading at 98f
the thermostat STARTS to open @ 176f
the thermostat should be fully open @ 183f
the fan turns on when the bike reaches 220f, and continue to operate until the bike is brought down to 212f
the fan will still operate if the motor is off, key in ignition, and ignition is on, and the bike temp is over 220f, and it will continue to still operate until the coolant in the system is brought down to 212f
operation of the bike to the 240 - 250F range is acceptable, how ever this is the range where you would want to find a safe place to park

Metric

the temp gauge starts reading at 36C
the thermostat STARTS to open @ 80C
the thermostat should be fully open @ 84C
the fan turns on when the bike reaches 104C, and continue to operate until the bike is brought down to 93C
the fan will still operate if the motor is off, key in ignition, and ignition is on, and the bike temp is over 104C, and it will continue to still operate until the coolant in the system is brought down to 93c

operation of the bike to the 115 - 120C range is acceptable, how ever this is the range where you would want to find a safe place to park

The standard mix of Coolant (ethylene glycol - with corrosion protection inhibitors) is a 50%/50% mix of cooland and distilled (soft) water

The radiator and engine contains 3.2 Liters (or 3.4 US Quarts)
the Reserve tank contains .3 Liters (or .32 quarts)

the radiator pressure limits are 108-137 kPa (or 16-20 PSI) .. note, this is the pressure range where coolant should be switching to the reserve tank as an over flow

the thermostat as from start to open to full open should have an 8mm lift (the valve moves 8mm from full closed, to full open)

to sum things up... any thing below 250F or 121ish C is NORMAL 250 is flat out the over heat point

it is not uncommon for the bikes to get to 240F or 115C


All of this information was obtained from the shop manual

Thanks for the well put together information Tenjin. Like myself I am sure they are many others on the forum who this information will help by knowing that because the bike’s temp goes above 180 °F it is not over heating but normal running temp.
Last week I noticed my fan continued to run after switching off the bike with the key but while the key was in the on position. While I attributed this to the temp being to the point where the fan needed to kick in I did not know what this temp was. I now know what to expect.

This is great info and exactly what I've been looking for. I get low 230's sometimes in traffic and it FREAKS me out. Lol Now that I know it's completely normal I won't worry about it. Does anyone notice that their bike runs differently at high temps? I feel like mine is much more sluggish when I take off from a light at around 220 or higher.

:+1: on that...gotta give it a lil more throttle if shes hot. goes for your bike too :spank:

popping fuses

does running a constant high temp above 220 ruin the fan motor, I keep popping fuses due to circuit overload, and have already replaced the fan once after it went bad.

i wouldnt imagine so, though its possible ... how ever my bike has endured4 long, blazing hot summers in the arizona heat.

The only way that a high temp is going to affect your fan is if its doing damage to the windings (which is unlikely), otherwise you probably have an intermittent short on that circuit.

is guess i'm still a noob for asking this question...but what exactly does it mean when it says "thermostat starts to open"?

it means just that

the thermostat is not a on/off device

its a mechanical device, at the specified temp, the valve begins its journey to being fully opened as it gets warmer and warmer

untill that temp the tstat is nearly blocking all of the water from flowing

I worry when mine hits the high 220's......i think the highest i have ever seen is 233 and I thought I should stop and park my bike. Thanks for the info makes me feel a lot better when my temp goes up

It would, but that may cause other problems in itself depending on the climate your in.
