Overview[edit | edit source]
Big Bear Athena ProStreet
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.
Engine
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.
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).
Transmission
This is the original 6-speed design that revolutionized the American V-Twin industry. Yet, it's still the best overdrive 6-speed built to this day ...hands down. This Detroit built tranny is designed and manufactured to comfortably handle the power from our engines while looking good behind it.
Drivechain
Keeping with the mindset of making form and function coexisting, this newly designed proprietary primary is built tough and reliable along with a very sleek, new generation styled aesthetics with a cool BBC branded inspection cover. This primary drive is approximately 200% stronger than most other manufacturers primaries with its machined forged aluminum inner and outer cases. The dense aluminum material makes for a unit that does not flex under heavy torque, and absorbs most engine vibration. Another great attribute that sets this primary drive ahead of the curve is the triple seal design on the main shaft, as opposed to an industry standard single seal, insuring virtually no leaks. The starter motor shaft accessory plate is removable for an easy starter change-out. The internals utilize an easy-to-replace standard type clutch basket and a compensating sprocket for a smooth power transfer.
Electrical
We teamed up with Wire-Plus, the industry's leader in motorcycle electronics, to design a wiring harness with no compromises. Combine this harness with the high-end brand name electrical components like the Spyke charging system and the Crane ignition, and we're sure your seat time will be long. You won't be on the side of the road kicking rocks.
Frame
The Athena frame starts out in the same jig as the Sled, but has obvious design touches with the Hot Rod holes drilled out of the outer downtube sleeve and rear fender struts. This frame design is unique in that it has an extra stretch in the mid section of the frame behind the transMision. This allows for a low seat height from the oil tank being located behind the tranny as opposed to hanging on top of it. This ingenious drop seat makes for a motorcycle that feels and handles unbelievably balanced and a blast to ride. The sunken seat allows the rider to be positioned inside the chassis, boasting more control and adding to the unique sensation of riding low to the ground. And our design patent on this frame helps us keep the motorcycle unique from manufactured copy cats. The patented Devil's Tail swingarm is a new creation that finishes up the bike with that custom one-off look.
The frame is the foundation of the motorcycle's aesthetics and reliability. All our frames are designed and manufactured in house in our San Bernardino facility. Every frame component (e.g. neck, side plates, tank mounts, tranny plate, axle adjusters, etc) are CNC manufactured with precision. Utilizing a 0.250 wall, 1.5 tube steel for the backbone and 0.160 wall, 1.125 tube for the rest of the frame, BBC uses the best steel possible for our frames. All frames are 100% TIG welded for a clean, strong and precise fusion. We think we make a statement about our confidence with a lifetime warranty on the frames we make.
The Athena Series sheetmetal goes beyond the standard with it's
hole drilled outer skins on the oil tank and the hand made
sheetmetal molding the seat's wishbone tube into the fuel tank.
Another aspect of the sheetmetal that stands out from the rest
is the trick rear fender design that matches the patented
Devil's Tail swingarm.
Like our frames, our tanks and fenders are designed and manufactured in-house. We produce the sheetmetal with the frame as a unit, then gets 'mock-up' before we hand it over to our painters or ship it out to the unassembled kit customers. We use heavy duty 12 gauge steel for our fenders and 14 gauge steel for the tanks. All tanks are pressure tested and the fenders are computer cut. We guarantee and warranty any leaks from the tanks and cracks in the fenders for your lifetime.
Suspension
Designed and manufactured in-house, our fully chrome frontend is exclusively made for our motorcycles to be aesthetically cool and functionally bomb proof. The BBC logo branded 6° triple trees have what we call a 'smooth mount' design - you don't see the tube and axle nuts on top. And what we mean with the 'hidden axle' - it's a nutless type axle, making the finish smooth. With all our calculations with the frame and frontend, we've landed the front wheel in the sweet spot of the final trail measurement. This allows for a motorcycle with no frontend flop and high speed wobble.
And at the back, there's no better American Made shock to use than the industry's premier shock absorber, Progressive Suspension. The chrome pair of oil dampened shocks produce a good ride, which is just one more reason why our motorcycles out handle and beat the comfort of the other guys bikes.
