Options 1 : BBC-S&S V111™ Carb Evolution

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.

Options 2 : BBC-S&S V111™ EFI Evolution

Between the EFI and the carbureted V111™, there isn’t 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 that’s 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).

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 manufacturer’s 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.

The Devil’s Advocate Chopper frame borrows the looks of our Venom frame with it’s single downtube and Venom swingarm, but is equipped with a larger 280mm rear tire and different tanks and fenders. We also threw out the seat post in the D.A.’s for style points.

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 downtube and a 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.

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.

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.

About the author


Engineering is the applied science of acquiring and applying knowledge to design, analysis, and/or construction of product. You can’t produce a great motorcycle without great engineering. And we’ve got a great engineering team and processes! The reliability, comfort and esthetics are only as good as the complete engineering of the vehicle. So in our efforts of providing our customers with an absolute motorcycle, meaning everything a motorcycle is; from performance, to design, with comfort and overall reliability, our engineering processes and staff run at high standards, efficiently and effectively. In all elements of engineering, e.g. manpower, methods, machinery and materials, our talented team uses well thought out methods with some of the finest equipment using premium material for every application.


Lets start with our engineering manpower and why we say they are talented. Our engineers use technology, mathematics, and scientific knowledge to solve practical problems. Each engineer in the team comes from a relative professional background and contributes their particular history and talent uniquely to the overall product development. Some of these backgrounds are from Fortune 500 companies that include Aerospace, Semiconductor Electronics, Automotive, Metrology and, of course, the Motorcycle industry, with decades of combined experience.

We have appointed responsibility to an engineer to direct each of these categories; Design, Manufacturing, Mechanical, Quality and Lean Manufacturing. Each engineer operates at high individual responsibility while working together as a team to ultimately produce a blameless product.


So now you know we’ve got great people. Let’s talk about their Methods. Firstly, concept theory is introduced by the R&D Chief Designer, who produces a concept pen and paper sketch. Our Digital Modeling Engineer works closely with our Designer and takes the concept drawing he created and renders a 3D image of the part or new model design, using state-of-the-art C.A.D. applications. We review the digital rendering with the team and brainstorm the design with functionality and engineering reasoning.

Computer Drafting

Once approved, the manual prototype fabrication of that particular part or the new motorcycle model design starts. Scale models are then developed and reverse engineered with laser scanners and 3D modeling. Or, we utilize our ultramodern Rapid Prototyping Printer to sculpt a solid 1:1 formed prototype straight from the C.A.D. rendering, and test fit. Once we get a prototype part from our real time tooling, we analyze and evaluate it on our test vehicles and make any necessary changes to the tooling before production.

Manufacturing & Lean Engineering

Once in production, quality control measures are implemented to assure proper fit, integrity of materials and design execution are at our satisfaction. And our satisfaction is to exceed our customer’s expectations, bottom line.
The material we use is just as important as the machines and the engineers behind them. A lifetime warranty on the frame, fenders, fuel and oil tanks should speak for itself about the quality of our product and the confidence we have about it. But let’s break down the particulars.


D.O.M. Steel Tubing

Drawn Over Mandrel 1018 Steel Tube (D.O.M.) is a very effective and strong tubing due to the high strength from the cold working process, it’s actually a friction pressure lap weld that forms the tube, resulting in a seamless and bulletproof tube. There is no type of filler used and the tube is drawn over a spinning mandrel by two other spinning mandrels. The extreme pressure and friction from the spinning roller welds the pipe. We use this DOM steel tubing for all frame manufacturing.

A36 Steel Plate

A36 Steel Plate has high yield strength and is used for all plate mounts for the frame such as transMision, engine, fuel and oil tank mounts, as well as side plates, axle adjusters and anything else on the frame that is of a two dimensional form.

Sheet Metal

The Sheet Metal we use is thicker than the standard in motorcycle manufacturing, utilizing a 12 gauge steel fenders and 14 gauge for tanks. These components are Deep Drawn, meaning, “drawing” the material further down into a geometric die until the final shape is acquired. This process produces a very accurate shape, resulting in minimal process variation and fundamentally measures perfect with every piece. Once the pieces are ‘drawn,’ they get Pickled & Oiled (P & O), which is a process that is effective in removing substantially all of the oxide layer or scale from processed sheet metal, thus prevents surface rust during the manufacturing process.

6061 T6 Aluminum

6061 T6 Aluminum is the high, aerospace grade material we use for all aluminum components, (e.g. the front-end’s triple trees and lower legs, foot controls, wheels and pulleys, our accessory assortment, etc.). These items are machined from an aluminum block, which are an alloy, magnesium and silicon as the alloying elements. It has great mechanical properties and is heat treatable and weld-able, not to mention lightweight.


Forging is the best possible manufacturing process when high strength is demanded, with a constraint on the mass of the part (high strength-to-mass ratio). Forging results in metal that is stronger than cast or machined metal parts. This is because during forging, the metal’s grain flow changes into the shape of the part, making it stronger. These parts require a specific grain flow to ensure the strength and reliability of the part. Pictured to the left is our outter Primary Drive cover right being Forged, and ready for machining in our Haas CNC machines. Other components we forge are our wheels.


Functionality and Saftey. Our testing and product analysis is not taken lightly here at Rage Hard Choppers Inc. We do not believe in providing our customers anything untested. Everything is proven with engineering and real life testing. So who’s the Test Team? It’s our designers, engineers, R&D guys and, you can’t forget, our test riders. Whof will test and analyze these bikes and their parts. Saftey is our number one priorty.

Ergonomics Testing

Ergonomics. Once the structural, functional, aesthetic, and safety levels are at our high standards, it doesn’t stop there. We test our motorcycles for the ergonomics. Ergonomics is the relationship between the rider and motorcycle, which includes comfort and how it handles. No matter how good the engineering is, the only way to develop a good ergonomic motorcycle is to ride and evaluate it. We believe in motorcycles that not only look good, but handle well with comfort.

Test Team and Environment.

Nestled at the base of the San Bernardino mountains of California, our roads and weather can be tricky -meaning great test roads, and hours from the heat of Death Valley and the rough freeways of Los Angeles, San Bernardino is in the middle of such diverse climate and land that it makes for a perfect test environment. Cold snow, slippery ice, annoying rain, desert heat, high winds, city traffic, rough freeways, hundred plus speed on highways, whatever, bring it on. Our test team is paid to ride in and through all of that. And not just ride, but ride hard. Rev it up, lean it over, mash the breaks, everything to the limits, to make sure all of our customers are safe with a great handling and reliable motorcycle. Our team of riders are retired professionals from the California Highway Patrol Motorcycle division with nothing better to do than to put 2000 hard miles a week on our test machines.
