MV F4 CC Feature
The F4 CC is at the absolute top of the F4 hierarchy. The main differences between it and the more “commercial” F4R can be summed up as follows:
– over 90% of the components are individually tailor made;
– brake and clutch levers that “fold” at the tip in the event of a fall;
– 1078 cc engine;
– 200 CV maximum power with titanium racing exhaust system;
– new timing system;
– smaller alternator;
– one-off mechanical type slipper clutch;
– new forks interior set-up and mono shock absorber
– Brembo Racing monoblock brakes;
– kerb weight 187 kilos without fuel.
All 1000 cc engines like that in the F4R have been tuned more and more not just to provide better performance, but also to better use the dynamics of four cylinders working in unison. This is why we increased the bore from 76 mm to 79 and left the stroke unchanged at 55 mm. Cubic capacity thus became 1078 cc – the maximum obtainable from this engine. This is where the MV Agusta racing department managed by Andea Goggi began to work. Their aim was to improve internal fluid dynamics by polishing ducts and working their magic on “chamfering the innards” to gain a few CV. The new combustion chamber geometry was part of an overall reworking of the heads where computer controlled equipment guaranteed work of the very highest order. The pistons were made lighter than those in the 1000 and con-rod geometry was changed. The real difference however lies in the timing system that was made from different sized exotic materials for each and every element. The intake and exhaust valves are still radial (unique MV AGUSTA figure), but are now titanium and the intake valves are now bigger measuring 31 instead of 29 mm. With the wider bore, changes were also needed to the camshaft profile. On the other hand, the valve bowls (still steel) were decreased in size to lose a few grammes weight. They were decreased from 28 to 26 mm but still have double springs. These bowls, along with the keepers, valve guides and valve seats are all made by Del West, the American market leader in this sector, and despite the exorbitant price of these components, they were perfect for a machine as exclusive as the F4CC. The weight saved by these higher working speed components led to improved engine “usability” not to mention the fact that they shaved 4 kilos off the weight of the F4CC engine as against the F4R. Other components that contributed to weight savings were the magnesium timing, gearbox, clutch, blow-by and alternator covers.
The alternator cover in particular made a significant difference to the scales given that it alone made a difference of about 2 kilos in comparison to the one fitted to the F4R.
Size, obviously makes a difference so the new smaller version meant modifications had to be made to the upper block due to the shape of the new alternator and new hose connections. The fuel feed system included bigger throttle bodies that went to 48 mm as against the 46 mm ones fitted to the F4R. Like the F4 1000 Tamburini, the key to the F4CC engine performance lies with the revolutionary, patented Torque Shift System (TSS). The end result is again an engine without parallel. Like its 2007 “R” sister, the F4CC fully complies with Euro 3 standards with the following components: lambda probe, catalyser and one-piece exhaust system. The Engine Brake System (EBS) must also be mentioned. This acts as a torque limiter under deceleration. This system was first launched with the F4 1000 series. The F4CC also features a mechanical type slipper clutch with ramps and roller bearings. It is a one-off item of equipment.
