What is the size comparison between the 1000cc bikes (RR/954/etc.) and the 600cc bikes (F4/F4i)? I would certainly think the 1000cc bike has a larger radiator, but by how much?

Dimensions of the 1000cc radiators (any/all) would be helpful.

I'm curious because I'm thinking of ways to upgrade the cooling system on my F4 build (my F4 radiator is trashed anyways).

Thanks,
Chris

 

I too am interested, more for educational purposes.

 

not necessarily.

it all depends on the way its engineered to cool down. 1000rr radiators and even 600rr radiators are bigger than 954 radiators.


oil cooled bikes (like ducatis /older gixxers) have tiny oil coolers to big oil coolers.


air cooled bikes don't have radiators


sheer displacement does not equate to heat. compression, piston speed (now you're getting into the stroke vs rpms), have a HUGE roll in how much heat is produced and how much cooling is needed.

and when compared to your bikes.... the 1000rr has higher compression, more stroke, higher rpms, so it needs a lot more cooling than an f4/f4i does. while i'm sure the hoses are bigger, and the coolant passages inside the motor are bigger, the radiator is too.

i'm going to be using on a 1000rr radiator on my 954 because of its increased capacity for coolant. it's a lot taller. more surface area to cool down coolant. BUT i'm not worried about dimensions because it's a naked bike. it depends on where the thermo pill is too. is it on your radiator or is it on the valve that opens and closes the coolant passages? i'm sure you could make any radiator work that you wanted - but i don't know the dimensions so that you could still use your fairings.
