2017 Big Bear Choppers Athena ProStreet BBC-S&S V111 EFI Evolution

Our Athena ProStreets striking stance comes from the lowered frontend with a sunken seat, making her sleek and slammed. This long and low machine handles remarkably well because of her low center of gravity and balanced ergonomics. The sunken seat allows you to be positioned inside the chassis, adding to the unique sensation of riding low to the ground. The hot rod hole drilled outer skins on the stretched patented frame, her Devils Tail swingarm with matching rear fender and the artistically created fuel tank are some of the unique characteristics of the Athena ProStreet that gives her a head-turning, custom one-off impression, but with the reliability and ridability of an extensive engineered production motorcycle. The V111" low vibration powerplant adds to the reliability of the motorcycle with a high comfort level of the rider without sacrificing power and price. The Athena ProStreet is a unique fusion of power, elegance and comfort that pushes the boundaries of riding pleasure. Unlike everything else out there, its unlike everything thats out there.

Between the EFI and the carbureted V111, there isnt going to be much of a difference in performance, provided you maintain constant ambient conditions (humidity, temperature, elevation, etc.). This is where the beauty of the closed-loop EFI system comes into play. The system is continuously monitoring the engine, and tuning itself to optimize performance for that given scenario or environment. So, while you might not be able to notice power difference between the EFI and a carbureted engine, once you take that bike up the mountain, or get a day thats significantly hotter than the day it was tuned, that EFI engine will easily outperform the carbureted engine (unless you want to take a supply of different jets with you on the ride).

Reliability, power and comfort... the best of all worlds. And when we say reliability, we not only mean the life of the engine, but the life of motorcycle and everything that's bolted to it. Branded as V111,' this internally reformed 111 cubic inch engine boasts a healthy 122.8 lbs. of torque at the crank. With a configuration of a 4 1/8 bore and 4 1/8 stroke, proprietary compression ratios, redesigned cam timing, and reciprocating weights all result in an incredibly smooth running engine while meeting all the strict legal requirements. While looking like any other S&S Super Sidewinder engine from the outside, the essence of this new engine is the low vibration. High engine vibration is an enemy to both the rider and the motorcycle. The effects of high engine vibration may cause premature rider fatigue as well. Eliminate engine vibration and you will eliminate potential problems.
