The Energica Ego is an electrically propelled sport road motorcycle designed and marketed by Energica Motor Company. It is claimed by Energica to be the world's first street-legal electric Italian sport motorcycle. The prototype was finished in 2013 and the vehicle came into the market in 2015.[1][2] The prototype made use of new technologies such as CNC and 3D-printing, including the dashboard and headlights which were 3D-printed.[3][4]

Design

The Ego is an all-electric motorcycle. It has a 107 kW motor with 200 N⋅m of torque (at low RPM), giving it a top speed of 240 km/h.[5][6] The motor is powered by an 11.7 kW⋅h battery. The Ego weighs approximately 258–280 kg, contributed to by the heavy battery.[7][8]

It has four-level adjustable engine braking, which is also regenerative.[9] The motor is situated near the cast aluminium swing-arm and side-mounted mono shock. Projector headlamps are used for headlights.[10] The dashboard is a 109.22 mm TFT display.[10]

Before 2017, it had a 136 hp electric motor with 180 Nm torque.[11] However, the naked sibling 'Eva' produces 108 hp which was 95 hp before 2017. They are also EURO IV compliant after 2017.[11][12] The price was also reduced to approximately £20,000.[13]

The bike has a tubular steel trellis frame partly visible despite the fairings.[14]

Upgraded again in 2019, they are equipped with an electric throttle that can read adjustments down to tenths of mrad. Other electronic features such as "silent charging" and heated hand grips were also added.[15]

Performance

The Ego reaches 0–100 km/h in 3 seconds. It has 43 mm Marzocchi suspension in front along with parking assist and Brembo brakes with features such as ABS and anti-rollover systems.[7] According to some reviewers, the suspension is relatively softly calibrated. It has a controller named a "VCU" by Energica, similar to an ESC. It is claimed to be controlling all aspects - from battery to engine (including engine braking) by Energica.

The EGO has a range of approximately 160 km under normal use (190 km in "eco" mode).[7]

The battery can be recharged to 85% in 30 minutes at fast charging station (mode 4, DC fast charge), or 100% in 3 and half hours (mode 2 or 3, 240 V). However, it takes 8 hours to full charge on standard US power supply of 120 V. The battery life is 1200 cycles at 80% capacity.[16]

Production

The first prototype was finished by Energica in 2013, and the vehicle went into production later with sales starting from 2015. According to Top Speed, currently it is facing "Inventory shortage" as the production is less than demand.[17]

MotoE

Energica Ego at Fully Charged in 2022

An electric motorcycle class (MotoE) was added as a support class to Grand Prix motorcycle racing from 2019.[6] It is a single make class, unlike the other class races which are between different manufacturers. A performance oriented model Ego Corsa is used for MotoE.[18][19]

Ego Corsa

It is the race track variant of the Ego with Michelin tires and performance tweaks. According to Energica, its motor produces 120 kW (previously 110 kW) continuous power and 200 Nm torque, reaching a top speed of 168 mph (previously 155 mph).[20] Acceleration from 0 to 60 mph is less than 2.8 seconds. According to Power and Top speed, the race track Ego will have a power at least 149PS and top speed of 175 mph (281 km/h).[21]

The battery is 20 kWh lithium ion, lighter and more compact than standard Ego.

The power output is comparable to the Moto2 class (three-cylinder 765 cc); however, due to the heavier weight of the bikes because of the batteries, the power-to-weight ratio is comparatively closer to the Moto3 class (single-cylinder 250 cc). Of the four circuits used so far, only the hilly Red Bull Ring has resulted in quicker laptimes than the Moto3 class, with the electric bikes typically being 1–1.5 seconds per lap slower.

The longest race so far has been 29.582 kilometres (18.381 mi).

Ego 45

On 45th anniversary of Energica's parent company, CRP Group, a special version of Energica Ego, the Ego 45, was introduced at Top Marques Monaco 2014 show.[22]
