In a sea of TV assemblers, ECOSSE takes a decidedly different approach. Quite simply: “If it’s easy, they don’t do it.” To begin, ECOSSE handcrafts and machines every possible part in the Denver factory. This includes tooling and pouring their own urethane seals, vibration-damping supports and chain guides. Bolts are custom designed and machined by ECOSSE and used throughout The Heretic, notably the oil banjo bolts & fittings and rear shock mounts. Motor and output sprockets are machined in-house. The intricate, tubular chassis (mainframe, swingarm and subframe) is meticulously cut, bent and TIG welded on site. What isn’t created in-house involves a strong collaboration between ECOSSE and its vendors to make the component unique.

Since much of Atchison’s inspiration was old Aston Martins and jet fighters with their acute attention to detail and precision craftsmanship, the real coup is the actual engineering behind The Heretic. Before any metal was cut or welded, the bike was designed and thoroughly tested using three-dimensional modeling software and Finite Element Analysis. The ergonomics were determined after a lengthy design process that entailed several different body types and load differentials to ensure maximum comfort for leg position, shifting, seat height and reach.

The materials chosen for construction are worthy in their own right: Aerospace-grade aluminum, carbon fiber for its unrivaled strength-to-weight ratio and 4130 chrome-moly for its high fatigue limit. In fact, The Heretic is the first motorcycle to have an entire chassis manufactured from titanium (Titanium Series) which boasts an even higher fatigue limit than chrome-moly and has a very beautiful, distinctive finish. A motorcycle of this caliber is constructed using only CNC machining & tube bending, hand-polished solid aluminum molds and absolutely no MIG welding. The result is a unique combination of old-world craftsmanship and computer-controlled accuracy.

Years of computer-based and real-world testing culminated with the glowing approval of an ornery, outspoken multi-time AMA Superbike Champ who took the bike through its paces on the windy streets of North Carolina. The Heretic was ready for delivery to a fortunate few. 100 to be exact.

A striking piece with every item a work of art in its own right.

Each piece of bodywork undergoes a rigorous development process. After thoughtful design using foam, fiberglass and computer models to ensure the lines are just right, files are sent to CNC machines where precise molds are cut from solid blocks of billet aluminum. After hundreds of hours of hand polishing, these aluminum molds become the tools for the precise lay-up of multiple layers of carbon fiber. Carbon Fiber that’s transformed into beautiful, extremely light, puncture-resistant bodywork.

Once painstakingly polished, by hand, aluminum tools ensure the highest level of consistency for every carbon–fiber Heretic body part.

To keep The Heretic’s weight to a nimble 452 lbs., every piece of bodywork is meticulously handcrafted from carbon fiber. The gas tank is intertwined with a complex matrix of varying layers of carbon fiber, Kevlar and fiberglass to ensure “crushability” while retaining fluids. In the event of impact, Kevlar and fiberglass help dissipate the energy, thus eliminating a serious, costly crack effect down the entire tank.

The remaining bodywork — headlight housing, tail section, both fenders, tach shroud and seat pans — is hand formed from three layers of carbon fiber. Finally, each piece is hand painted with numerous clear coats to highlight the exotic material as well as protect against UV damage.

Major components

0 to 60 in 2.8 seconds. Over 140 ft-lbs of torque at very low rpms.

Most torque, least vibration. Carved from solid billet aluminum. Each dynamically balanced and blueprinted. 1640cc to 1966cc.

Ultra-compact design, ultra smooth with perfectly spaced ratios. Shift throws are short with positive, predictable engagement. Six speed with overdrive gear.

Custom collaboration between ECOSSE and Öhlins. Fully adjustable forks custom fitted with special internals. Rear shock provides an unprecedented 6.5" of plush rear wheel travel and adjustability on the fly. You might actually want to ride The Heretic cross-country.

Radial Brake System
Arguably more stopping power than even Moto GP’s incredible machines. Six enormous pistons (each with its own individual brake pad) tackle the braking — four positioned between the radial mounting points with two more trailed below. Since the intricately machined radial calipers are so powerful, ECOSSE uses an easily-adjustable front radial master cylinder allowing each Heretic owner to immediately customize their desired stopping power. To address the different lengths of customers’ fingers, ECOSSE went the extra mile to provide adjustable reach for the front brake lever and clutch lever. ECOSSE’s acute attention to detail continues with an integral fluid reservoir for the front brake master cylinder with the required DOT verbiage machined directly into the surface.

Exquiste details

Starter button
The red starter button doubles as the oil indicator light. Once oil pressure is detected, the light immediately goes out (preventing an annoying glow while riding)

Programmable tachometer (digital speedometer included in display)
The digital speedometer has an internal stop watch to clock 0-60 and 0-100 mph times as well as your best quarter-mile pass. Customize your dash with numerous settings: Timed intervals, programmable shift lights, needle color choices, brightness levels…

Rotors/chain basket cover
The wheel spoke pattern is echoed in the machined brake rotors and the chain basket cover

Oil dipstick/nuts
The dipstick, axle nuts, and countless other bolts/fittings share the same intricate ECOSSE pattern.

The turn signals are specially fitted with ultra bright LEDs for maximum visibility. 3M reflective wire sheaths offer vibrant visibility for added safety. Sleek turn signals self-cancel after 11 flashes or can be manually turned off by depressing the white button. The required DOT verbiage is machined directly into the surface contributing to the clean, stunning appearance.
