The two RR models share most engine updates and some chassis tweaks. The 798-cc, 12-valve powerplant is mechanically unchanged, but its intake system is revamped with a reshaped airbox, larger 50-mm throttle bodies and twin instead of single injectors per cylinder. The signature trio of stubby silencers remains but they’re new and breathe more freely. The result is enhanced mid-range torque and a 15-PS boost in peak power output to a very healthy maximum of 140 PS at 13,100 RPM.
This wouldn’t be a new MV without an updated electronics package, and this time the change is significant. Alongside further revised fuelling incorporating four riding modes, one of which is customisable, the RR models are fitted with a standard fitment quick-shifter which, in conjunction with the slipper clutch, allows clutch-less changes on both up- and down-shifts. Like the standard Brutale and Dragster the RR models get an eight-level traction control system, adjustable via a button on the left bar.
There’s no change to the basic chassis layout, based on a compact steel-tube-and-aluminium frame and single-sided swing-arm. Suspension at both ends is firmed up slightly to cope with the extra performance, the Dragster RR’s slightly more so. Forks are new 43-mm upside down (USD) Marzocchis with lighter, gold-anodised sliders, and super-tough DLC (Diamond-Like Carbon) coated stanchions that are also made from aluminium, saving a total of over a kilo in weight.
Both models also feature an uprated brake system that combines Brembo four-pot radial callipers with Bosch ABS, incorporating an anti-stoppie function called RLM (for Rear-wheel Lift-up Mitigation).
