How does it compare?
Speed
Hold onto your knickers because the Ultraviolette F77 boasts a top speed of 91 mph (146 km/h). While its no slouch, the Zero SR/F rips through the tarmac at 124 mph (200 km/h), making it faster by a considerable margin. The Harley-Davidson LiveWire, in true American spirit, cruises confidently at 95 mph (153 km/h), whereas the Italian stallion, Energica Ego, roars ahead at a blistering 150 mph (241 km/h).
Range
When it comes to going the distance, the Ultraviolette F77 claims a respectable 93 miles (150 km) on a single charge. This sits snugly between the Harley-Davidson LiveWire, which musters a commendable 140 miles (225 km), and the Zero SR/F, which stretches its legs significantly further, reaching up to 161 miles (259 km). On the upper echelon, the Energica Ego allots a range of approximately 120 miles (193 km) under average riding conditions.
Power
Gunning the throttle on the Ultraviolette F77 unleashes 33.5 hp (25 kW), which, while potent, pales in comparison to the sheer muscularity of the Zero SR/F at a whopping 110 hp (82 kW). The Harley-Davidson LiveWire stands powerfully at 105 hp (78 kW), and the Energica Ego towers with its ferocious 145 hp (108 kW), all but snarling at its electric kin.
Charging Time
Need to juice up? The Ultraviolette F77 takes around 5 hours on standard charging, but a fast charger drops that to 1.5 hours. Meanwhile, the Zero SR/F needs 4.5 hours for a complete charge but also benefits from a rapid charger slashing that to about 1.5 hours. The grand Energica Ego impresses with a fast-charge option achieving 80% in just 30 minutes, making the competition look sluggish. The proud Harley-Davidson LiveWire refuels in roughly 12 hours on a standard charger, or, if youre impatient as we tend to be, quick charges in 40 minutes to 80%.
Price
Here’s where wallet-waffling kicks in. The Ultraviolette F77 is a veritable bargain at approximately $4,500 (GBP 3,700 / EUR 4,200). Meanwhile, the Zero SR/F will set you back around $18,995 (GBP 15,550 / EUR 17,800). The iconic Harley-Davidson LiveWire demands a princely sum of $29,799 (GBP 24,390 / EUR 28,000), and the Energica Ego stakes its claim at $29,000 (GBP 23,750 / EUR 27,250).
