Running temperature

Hi people
Having only just started riding my new bike I noticed that at a standstill it shoots over 100 on the dashboard for temperature.
It doesnít feel too hot or smell just wandered if this is the normal temperature range.
Cheers

Most every sport bike made runs around 100C normally. Fans don't generally come on until 105~110 and cut back off at 100. Totally normal.

Some brands don't give you numbers, just a gauge or line bar...that's so you won't freak out when you see 100 C all the time.

Now the F4... with the aero body work it doesn't let much air get through the radiator when you aren't moving. That bike is not designed to sit still !!!
Lot's of threads on cooling the old F4 down.

I used to be fast....now I just dream about it.

Thatís cool then!
I just donít remember seeing it shoot up that fast on my dukes or other bikes Iíve had.
Youíre quite right though it doesnít go above 105.
It does feel ok as well whereas when the fans cut in on my 998 its the equivalent to having my nuts roasted

When I first got my 312r stuck in heavy traffic the temp just kept climbing until the dash started flashing and I shut the bike down thinking it had a cooling issue. If you search on this site however you will find it's referred to pretty much as an undocumented feature of Gen 1 F4s and especially 312 models.
I went the route of fitting an additional fan from a 1098 with a separate relay plus override and upgraded the water pump and coolant. Doesn't sound like yours is getting that hot so maybe it's had some work done already.

You could fit a manual fan switch.
It is cheap to fit and works well.

My 312r continued to overheat at standstill even when the original fans were running. Hence installing the extra fan. The later Ducati fans are much more efficient so move far more air through the rad. Some people fit larger single piece radiators especially as the original ones have a habit of falling apart under their own weight. Adding an extra fan with proper brackets also supports the side of the radiator prone to failure.

Thumbs up ?

Farshore;
MVs run hot .....the problem is the ECU mapping and the fan switching temperature, also the EBS system is a POS
They have way more radiator core volume than Ducatis or Aprilias at the same HP level

Read this thread;
http://www.mvagusta.net/forum/21-cus...-software.html

I have an '08 Brutale 910R with a MicroTec ECU......fans come on at 85C, park it in the sun and let it idle for 20 minutes
It will NOT go over 92C with the ass end facing the wind

F4s run hot but 312s run hotter not least because most of them, except this chaps' have that lovely aluminium mesh plugging all the ventilation holes in the fairings. Installing upgraded water pumps, override switches and engine ice doesn't pass air through the rad like a high performance properly ducted fan, the fix which sorted my 312r. My 1090rr can sit in baking weather at idle without breaking a sweat in comparison thanks to the lack of air restriction around the bike. The story I heard was that in Italy if you bought an F4 and it overheated in traffic the salesman would tell you that to drive in traffic you needed a Brutale not an F4 so you should buy one of those as well.
As stated above another really good reason to install an extra fan is to provide support to the radiator so it doesn't fail.
