Stuart -

Man, this is the only thing I found after a twenty minute search... And no tellin' what temperature scale those Aussies are using! :lol:

And after reading this, it looks like it's not specific to your bike, but rather to what oil you're using... I may have missed the mark on this one, but I hope it helps a little. ?

Isn't it always running... in our heads? :D

Rowdy - yes it is.

Stuart - why do you want to know? As long as the bike is not overheating - and the gauge will tell you that. What difference does it make what the actual temp is in degrees?

I am a collision investigater with Thames Vally Police in the UK and I am dealing with a crash involving a Hayabusa. The engine oil was spilt over the road and I am trying to establish if it could have been at such a temperature to melt the bitumen in the road. This could prove that the motorcyclist was on his correct side of the road when the crash happened.

That's a tough one. My bike's oil varies between 80 and 110*C, but it's air cooled. Most liquid cooled bikes don't have oil temp gauges. Not many 'Busa owners here. You might have better luck here.

The other option (and probably better for court) would be to reconstruct the event.

Get a Hayabusa with similar mods, have it ridden so the oil is at operating temperature, drain some off and apply it to bitumen in the same section of road under the same weather conditions. Or something like that.

There are so many variables though. How hard was the bike being ridden, (i.e. was the 'Busa rider cruising along in third gear on an open road or was he trying to set a land speed record)?

Post crash, how long before the oil made it onto the road, (i.e. did it sit in a slightly cracked engine case and seep out as the engine cooled or was it ejaculated at it's highest temperature during the crash)?

[Beavis....heh heh heh...he said ejaculated...heh heh heh...]

You're probably going to get further concentrating on tire skidmarks and other marks left on the surfaces involved.

It's interesting. Please keep us posted.

I was recently riding with an acquaintance who got taken out by a scooter-Nazi. The engine case on his X-11 cracked and oil seeped out within a few minutes. It didn't melt the Tokyo asphalt beneath it.

I'd guess the X-11 and Hayabusa, being ridden together, would be operating at oil temps consistent with each other. Just a guess.

Like you have said, there are so many variables, it is a very difficult one to start with. I have tried for several weeks searching the internet with every search engine I could find to try and get some idea (or even a range) of the oil temperature. I have not even got close !!!!

The best I have managed is to find an oil expert who has worked with the Honda, Suzuki, Kawasaki and Ducati race teams and can say that generally, motorcycles will run at les than 100 degrees C.

The circumstances are a moderately warm evening with an average size rider and an average size pillion. From what I can gather, they had only travelled about 4 miles before the collision and all of that was in a residential area.

The rider claims that when he collided with the car, it split the offside crank case and the oil sensor valve came out, so the oil would have been ejected from the engine under pressure.

I have carried out a test on the road surface with semi synthetic 10W-40 heated to 105 degree C and it had not effect on the bitumen at all.

So that's where I have got to, but I could really do with knowing the temperature of the oil. It would make life a whole lot easier for me when I am standing up in court giving evidence.

Stuart.
