If you take your avenue bike out for a spin at a racetrack, in the event you’re good, you do not fill it to the highest with fuel. You place simply sufficient within the tank for the half-dozen laps that you’re going to do every session. Greater than that’s merely unhelpful ballast.
California-based start-up Lightfighter has prolonged that precept to the event of two electrical bikes aimed squarely at observe use. It is given them simply sufficient vary to fulfill the club-level racers and track-day lovers that it hopes to promote bikes to – and with that restraint, it has introduced jaw-dropping efficiency.
Essentially the most highly effective of Lightfighter’s two prototypes is the totally faired V3-RS. It produces 154 hp (115 kW) and weighs simply 399 lb (181 kg), the corporate says. And that is the ready-to-race weight, totally … umm … charged.
For a gas-fueled comparability, Ducati’s newest V-twin superbike, the Panigale V2, is claimed to weigh simply 4 lb (1.8 kg) much less – however that is with no gas within the tank. And it makes solely 120 hp (88 kW). Ducati’s four-cylinder equal, the Panigale V4, is far stronger than both, nevertheless it’s additionally heavier, at 421 lb (191 kg), and once more, that is earlier than you add gas.

The Lightfighter is as highly effective, whereas a lot lighter than the 575-lb (260-kg) behemoths raced within the MotoE World Championship (the premier worldwide collection for electrical bikes) – and the 489-lb (225-kg) e-Ducati that will have changed them had the category not been mothballed from subsequent yr.
Extra on level, the Lightfighter seems to be to be fast and light-weight sufficient to provide a non-pro as a lot velocity and finesse as they’d ever get from any road-going superbike on the observe. And that is with out the opposite benefits of an electrical powerplant – like at all times being in the proper gear.
Lightfighter’s CEO, Brian Wismann, says its superior specs are underpinned partly due to a extra energy-dense battery pack, and partly by a deal with minimizing weight – helped by US circuits usually being tighter and fewer energy-demanding than the high-speed tracks used within the MotoE collection.
The battery pack, sourced from Farasis Power’s analysis hub in California, can retailer simply 12.5 kWh – sufficient to energy the bike repeatedly at full throttle for about seven minutes straight, in the event you had sufficient runway.

Should you’re considering that is scanty, you have grossly underestimated the efficiency of a 400-lb, 150-hp motorcycle, even on an enormous circuit like Australia’s famed Phillip Island, one of many quickest grand prix tracks on the earth.
There, a talented rider may maintain full throttle for about eight seconds on the principle straight every lap, and one other few seconds on the downhill straight to Stoner Nook – a shallow left-hander that may be taken at 150 mph (240 km/h) in the event you’re sport. On a number of visits to the observe, I by no means have been. Then you definately’re counting gears as you downshift whereas braking for the near-hairpin right-hander that follows.
On the Lightfighter, after all, there aren’t any gears to alter – its 120 lb-ft (162 Nm) of torque is on the market from zero rpm, pulling you out of the hairpin in the identical gear that will get you to most velocity on the straight.

That simple rideability is a part of why Wismann thinks the Lightfighter could possibly be not solely a aggressive electrical racer towards its gasoline-fueled alternate options, but in addition one of the best bike obtainable for anybody driving for enjoyable moderately than revenue.
There are additionally weight-distribution benefits from the compact powerplant, together with what Wismann describes as nice dealing with in transitions – the rider does not should battle the gyroscopic resistance of an inside combustion engine’s heavier rotating components.
A Lightfighter’s battery, he says, might be recharged in an hour from the facility obtainable at typical US racetracks. “For a observe day, it’s doable for the rider to recharge between periods. We’ve the power to swap batteries, however have by no means finished this on the observe days or race occasions we have competed in,” Wissman informed New Atlas.
Amongst these occasions was an eight-lap AFM-sanctioned race on the 2.9-mile (4.67-km) Thunderhill Raceway East in Willows, California, in June. Brenden Ketelsen expertly rode the V3-RS and received – stretching the Lightfighter’s endurance to the restrict whereas turning a 1:50.026 time within the course of.

Lightfighter’s different prototype, labeled the V3-RH, is a 135-hp (100-kW) super-naked with greater handlebars and no fairing, constructed for acceptance into the skilled MotoAmerica Tremendous Hooligan collection subsequent yr.
The water-cooled motor for each bikes has been developed in collaboration with Ohio-based Parker Hannifin. It is set in a custom-built casing that additionally homes a 2:1 discount gearset, which doubles its torque output earlier than it reaches the drive sprocket.
The chassis and physique components will look acquainted to bike lovers, with Oz Racing wheels, high-end Ohlins suspension, and Brembo brakes, all tied collectively by a tubular metal trellis body drawn up by Lightfighter fabrication lead Ely Schless – who says he took a Yamaha R1 superbike as his place to begin.
Rake and path figures are an unexceptional 24.5 levels and 100 mm, with a wheelbase of 56.5 inches (1,435 mm). Tires are 120/70-17 entrance and 200/60-17 rear, whereas the {custom} bodywork combines carbon fiber and fiberglass.

The third of Lightfighter’s co-founders is chief know-how officer Nick Lambert, whose background consists of electrical motor know-how and 9 years overseeing high quality management and new-model introductions at Tesla.
Wismann left electrical bike maker Zero Bikes in Could after 9 years supervising product improvement to dedicate himself to what started as a ardour mission.
He says the workforce is devoted to elevating the corporate’s profile via racing whereas working towards a limited-production debut in 2027 – seemingly at a premium worth. Extra highly effective variations are within the pipeline.
As a long-time motorcyclist who has competed at membership degree, I discover the prospect of such an electrical racer engaging – partly as a result of it sharpens the deal with exploring the boundaries of dealing with and grip, and partly as a result of it could want rather a lot much less TLC between outings than a gas-fueled observe bike, a degree Wismann readily endorses.
Lightfighter
May Lightfighter – and the imitators prone to comply with – even elevate curiosity in observe driving, in a world the place trendy sportbike efficiency way back outpaced what could possibly be exploited prudently on public roads?
Whereas acknowledging that some riders will at all times desire the engagement that comes from clutching and shifting, Wismann believes an EV powertrain is the perfect answer for a track-focused bike.
“The facility supply is smoother than any combustion engine, and the act of piloting the bike is far less complicated and extra confidence-inspiring,” he informed New Atlas.
“The Lightfighter is infinitely tunable to be the bike you need it to be. We are able to program it to behave like a 400, a 650 twin, a 600 4 or a liter bike. It is a bike that may meet the rider the place they’re of their journey.
“We are able to clearly see that the following era of motorcyclist could have realized to journey on e-bikes and small electrical bikes. I feel there’s sturdy potential to increase curiosity in highway racing by interesting to this youthful era of rider.”
Yep, they usually might pull in some older riders as effectively.
