Eclectic Electrics: Brammo Enertia vs. Zero S

MC Comparison

By Ari Henning, Photography by Tim Sutton

Brammo Enertia | Price $7995

Dyno
Since there's no spark plug lead to tap into during dyno runs, determining motor rpm took some arithmetic. As with all electric motors, torque is abundant from anything above 0 rpm, with the Brammo putting down 41 lb.-ft. at 925 rpm and a modest 15.3 bhp at about 3100 rpm.

Ergos
A lower seat, higher bars and platform footrests that are a full 5 inches lower and several inches farther forward than the Zero's make the Enertia feel rather cruiserish. It's relaxed and roomy, which is excellent for tall riders, but still comfortable for shorter people.

Zero S | Price $9995
Dyno
More horsepower means more speed, and the Zero's extra 5 bhp translate to 10 mph on top. Its 50 lb.-ft. of torque is nothing to scoff at, and is what helps hustle the S off the line quicker than its competition.

Ergos
With a standard 34-inch seat height, wide bars and high footpegs, the Zero S feels exactly like your standard 250cc supermoto bike. Our only complaint was the agonizingly hard accessory low seat. If you're tall enough, stick with the softer stock saddle.
