Unlike the conventional chain-driven camshaft systems found on most four-stroke motorcycles, this Rotax engine utilizes a toothed timing belt behind the engine cover to operate the overhead camshaft.

This is one of the signature engineering details that makes these engines so interesting!

Rotax engines have earned an outstanding reputation for durability and performance in a variety of motorcycle applications, including enduro racing, motocross, flat track, hill climbing, and other competition disciplines.

Another distinctive feature is the twin exhaust outlets exiting the single-cylinder engine, feeding into the two-into-one exhaust system.

These big four-stroke singles have a fantastic exhaust note, excellent torque characteristics, and a personality all their own.

The six-speed transmission provides versatile gearing for off-road riding, with the potential for higher-speed operation when properly geared and equipped.

IMPORTANT: The engine kicks over and is not seized. We have not attempted to start or recommission the motorcycle, and its internal mechanical condition has not been verified.

PREMIUM AMERICAN-BUILT CHASSIS AND COMPONENTS

ATK motorcycles were designed with performance in mind, and the component selection reflects that philosophy.

Factory equipment and chassis highlights include:

• American-built chromoly steel chassis

• Premium WP suspension

• Distinctive side-mounted rear shock

• Linkageless rear suspension design

• Heavy-duty triple clamps

• Nissin disc brake equipment

• Factory Answer handlebars

• Approximately 37-inch seat height

• More than 13 inches of ground clearance

• Original-style gold wheel hubs

• Gold rear sprocket

• Electric-start equipment

• Original factory handlebar switchgear

One of the most recognizable ATK engineering features is the unusual rear suspension arrangement.

Rather than utilizing a conventional centrally mounted shock and linkage system, ATK employed a distinctive side-mounted rear shock design that helped separate these motorcycles from their competition.

The tall chassis, substantial ground clearance, and quality suspension components made these machines formidable off-road motorcycles, particularly for serious woods and enduro riding.

CONDITION – EXCELLENT RESTORATION FOUNDATION

What makes this particular motorcycle especially interesting is the condition of its major chassis components.

Although it needs mechanical recommissioning and cosmetic restoration, several important original components appear remarkably well preserved.

FRAME AND CHASSIS:

The chromoly frame appears exceptionally straight, with no visible dents in the lower frame rails.

This is particularly noteworthy on a motorcycle of this age. Many vintage dirt bikes have heavily battered lower frame rails from years of riding over rocks, logs, and difficult terrain.

This ATK shows no visible dents in those lower rails, suggesting it may have enjoyed a relatively sheltered riding life.

The swingarm sides also appear straight, and the major chassis components provide an excellent starting point for restoration.

ORIGINAL PLASTICS AND GRAPHICS:

The original-style plastics are present and appear substantially intact.

The fuel tank retains its original ATK graphics, including the patriotic red, white, and blue USA-inspired color scheme.

The graphics have faded considerably after more than three decades, but they are an excellent reminder of this motorcycle's American heritage.

A fresh set of graphics, some plastic refinishing or replacement, and a detailed chassis restoration could dramatically improve the appearance of this machine.

WHEELS AND TIRES:

The motorcycle retains its attractive gold wheel hubs and gold rear sprocket.

The front tire is a Kenda Washougal with approximately 90% visible tread remaining.

The chain shows wear and should be replaced as part of the restoration. A fresh gold chain would look fantastic alongside the factory-style gold sprocket.

The wheels, tires, bearings, and related components should all be inspected before returning the motorcycle to service.

CONTROLS AND ORIGINAL EQUIPMENT:

The factory-style Answer handlebars, heavy-duty triple clamps, and original handlebar switchgear remain in place.

The motorcycle also retains its kickstand and visible electric-start equipment.

The original turn-signal switchgear is present, although some of the turn-signal equipment is damaged or missing.

This is a great foundation for someone who appreciates original equipment and wants to preserve the character of an unusual American-built motorcycle.

KNOWN ISSUES / RESTORATION REQUIREMENTS

This ATK is being sold as an AS-IS, NON-RUNNING PROJECT MOTORCYCLE.

Known items requiring attention include:

• Front brake caliper is missing.

• Rear brake pedal/lever is missing.

• Turn-signal equipment is damaged or incomplete.

• Original tank graphics are heavily faded.

• Drive chain shows wear.

• Engine has not been started or tested.

• Fuel system will require inspection and likely servicing.

• Brakes will require repair and complete inspection.

• Tires, suspension, electrical system, and other mechanical components require inspection and recommissioning.

The previous owner reportedly misplaced the missing brake components during a move.

The engine does kick over, confirming it is not presently seized, but we have not performed a complete mechanical evaluation.

We recommend that the buyer plan on a full mechanical recommissioning before attempting to ride the motorcycle.

Additional issues may be discovered during restoration.

WHY ARE WE SELLING IT AS A PROJECT?

Here at Kaplan Cycles and the New England Motorcycle Museum, we have approximately 240 motorcycles in inventory awaiting service, recommissioning, or complete restoration.

Our restoration department has a backlog approaching a year and a half.

We simply cannot restore every motorcycle that comes through our doors.

Rather than having this rare ATK sit in storage waiting for its turn, we have decided to offer it directly to an enthusiast who can give it the attention it deserves.

A professional, comprehensive frame-off restoration on a machine like this could easily represent $7,000 or more in restoration work, depending on the final scope and parts requirements.

Instead of investing that money and time ourselves, we're offering this motorcycle in its present condition, allowing the next owner to take on the restoration and build it to their own specifications.

For the mechanically inclined enthusiast, this represents an excellent opportunity to get into a distinctive American-made classic without paying the price of a fully restored example.

A RARE AMERICAN CLASSIC WORTH SAVING

There is something special about these ATK motorcycles.

They represent a period when independent American motorcycle manufacturers were building innovative machines using quality materials, creative engineering, and some of the best components available anywhere in the world.

The combination of a Utah-built chromoly chassis, Austrian Rotax four-stroke powerplant, WP suspension, distinctive side-mounted rear shock, and patriotic ATK graphics gives this machine a character unlike anything produced by the major Japanese manufacturers.

Best of all, these motorcycles have a dedicated enthusiast following, and owners continue to maintain, restore, and ride them today.

Whether your goal is a period-correct restoration, a vintage woods-riding machine, an unusual addition to a motorcycle collection, or simply a conversation piece celebrating American motorcycle engineering, this 1994 ATK 350 deserves a closer look.

Imagine this motorcycle with a freshly refinished frame, restored plastics, new red, white, and blue graphics, a gold drive chain, fresh tires, and that Rotax four-stroke thumping through its distinctive exhaust!

It would be one seriously cool vintage enduro.

THE BOTTOM LINE

This is a rare opportunity to purchase an unusual American-built ATK 350 with its original character, quality chassis components, desirable Rotax engine, and distinctive factory equipment.

1994 ATK 350 – AMERICAN-BUILT – ROTAX FOUR-STROKE – SIX-SPEED – ELECTRIC START – WP SUSPENSION – RESTORATION PROJECT!

The motorcycle is NOT CURRENTLY RUNNING and is being offered AS-IS, EXACTLY AS SHOWN, with no representation that it is roadworthy or mechanically complete.

Please review all photographs carefully and contact us with any questions before purchasing.

Don't miss your opportunity to own and restore a truly unique piece of American dirt bike history!
