Lectro

"The aggressive styling and hyper tuned engine make this a bike that's ready for a fight. Most likely it'll be fighting the back of a truck or a highway barrier, but that'll be down to you. Features KERS Kinetic energy recovery system, which uses the bike's axle power to generate energy for the hyper cell battery. This power can be delivered to the back wheel via a direct drive brushless motor, giving the bike a hi torque speed boost."

- LegendaryMotorsport.net description. The Principe Lectro is a sportsbike featured in Grand Theft Auto Online, added as part of the Heists Update.

Description
The bike seems to be based on some sort of streetfighter motorcycle, possibly based on a Ducati Streetfighter S. The skeleton-style rear takes most of the inspiration from this. The bike also resembles a MV Agusta Brutale S.

GTA Online
"Kers" can be seen written on the bike. A Kinetic Energy Recovery System (a.k.a KERS) is an automotive system for recovering a moving vehicle's otherwise wasted kinetic energy under braking. Players can use the KERS boost by pressing the left stick to gain a boost which can be refilled by braking. The amount of boost left is shown in a horizontal bar graph under the radar.
