Wheels and tyres
While the Streetfighter V4 mounts cast aluminium 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminium alloy wheels.
The rims mount Pirelli Diablo Rosso Corsa II tyres. Combining track performance with road versatility, they come in the 120/70 ZR17 (front) and 200/60 ZR 17 (rear) sizes, already used extensively for slick tyres in the FIM Superbike World Championship.
The rear tyre compound has been designed by Pirelli specifically for the Streetfighter V4. It ensures the same dynamic behaviour as the Supercorsa SP race replica tyres mounted on the Panigale V4, but has better low temperature performance to ensure the versatility one expects from a naked.
Braking system with Brembo Stylema® monobloc calipers
The Streetfighter V4 range features powerful Brembo Stylema® monobloc calipers, developed out of the already high performance M50 calipers.
The dual Brembo calipers, each mounting four 30 mm pistons, bite down on 330 mm discs to give exceptional braking power. Rear braking, instead, relies on a single 245 mm disc clamped by a 2-piston caliper. Braking is aided by the ABS Cornering EVO system, which uses the ultra-light 9.1MP control unit.
As on racing bikes, the 16-litre aluminium tank has a section that extends under the seat. Compared to the Panigale V4, the lower section of the tank has been modified to allow installation of a seat with thicker padding to boost rider comfort.
Up front, the space not occupied by fuel has been used to house all the electronics, battery included.
