Brutale S cooling questions

I thought I'd put this out here and see what you tech guys had to offer. I test drove a '09 Brutale 1078 last weekend, (still talking with my credit union about a loan), but I noticed how much cooler it ran then my '04 750 S. I know MV upgraded to two radiator cooling fans on later model years. My question is, if I keep my 750, would it be possible to upgrade with a radiator from say an '06 910?

Brutale radiators are completely different than F4 radiators. The conversion can be done, Noel and Donsy have done it. I think Donsy had a thread about it. I don't remember if it worked.

radiators?

Roy and Carl;
i redesigned the F4 radiator and the whole cooling system
double pass upper, automotive radiator cap on top of the right tank, no lower, no heat exchanger, oil cooler instead
Donsy's oil temp is down 15deg C.....yes it works on the F4
my F4 only has 4 stock radiator hoses and a non pressurized line from the tank to the new filler neck

i did nothing to the Brutale.....i have an early Brutale radiator with a single fan....
my '08 910R has 2 fans
maybe Carl can tell you if the 910 and 750 radiators are the same....then you'd just need the 2nd fan

you should only need mounts for the 2nd fan, Lee used a Fusor product to glue them on!

Guys, the orig poster has an 04 Brutale 750 and is thinking about upgrading to a 09 Brutale 1078. If he dosent do that, he wants to know if he can upgrade his existing 04 Brutale 750 radiator to a newer 06 Brutale 910 radiator. Nowhere is an F4 invloved.

Hi Beast, when you say the newer Brutale runs cooler - what sort of temperatures are you referring to?

My 750 Brutale only gets warm if I'm idling in traffic during a hot Australian summer. Even then it's managable. I don't perceive a problem here - even if a 1078 Brutale were to run cooler again.

If you're having genuine issues with your 750 running too hot then I suggest that there is a problem somewhere that is not a direct result of the layout or intended operation of the cooling system. Perhaps the coolant is too old, or contaminated. Perhaps the thermostat is faulty. Something like that, rather than a fault with the original design.

Cheers

Thanks for all the info guys. I actually found a website (evolutionbike, or something to that accord) that has an upgraded metal fan blade and higher volume waterpump impeller, both licensed by MV Agusta, that I've got on order. Also Rents, my temp gauge gets around 221 degrees on a sweltering day here in the SouthEast US, the 1078 I rode didn't get over 205 degrees. I've got mine in the shop for an oil change and coolant exchange at the moment.

I wouldn't worry at all if you see 221 on hot days in traffic. That's running warm, not overheating. The coolant won't boil as long as it's in reasonable condition.
