1990 KTM LC4

1990 KTM 600 LC4 Enduro – Michigan Titled & Plated Survivor

Offered here is an increasingly difficult-to-find 1990 KTM 600 LC4 Enduro that has remained remarkably complete, documented, and well-preserved throughout its life. This motorcycle has had only three owners since new and comes from long-term enthusiast ownership in Michigan.

One of the most unique aspects of this motorcycle is its long-established street-legal history. Unlike many vintage enduros that were converted later in life, this motorcycle was equipped for road use when new through the selling dealership and has carried its plated history for decades. Enthusiasts familiar with vintage enduros understand the significance of a properly executed dealer-installed street-legal setup compared to later owner modifications.

This legendary LC4 liquid-cooled four-stroke "Thumper" retains its original character and presents as an honest survivor. It starts, runs, idles, and responds to throttle properly while showing authentic wear consistent with age and careful use.

Included with the motorcycle is an exceptional documentation package consisting of original KTM literature, owner's manuals, maintenance information, dealership paperwork, original dealer envelope, suspension documentation, registration history, and related materials accumulated over decades of ownership.

Condition:

This is not a restored motorcycle and is not represented as a museum piece. It is an honest, well-preserved survivor showing normal cosmetic wear consistent with age and use. The motorcycle presents exceptionally well for its age and remains complete, highly original, and mechanically sound. Please review all photographs carefully as they form part of the description.

Collector Notes:

The early LC4 models helped establish KTM's reputation in long-distance enduro, rally, and desert competition and represent an important chapter in KTM history. These big-bore KTM Thumpers developed a loyal following among enthusiasts for their durability, torque, and long-distance capability.

Complete, documented, titled examples have become increasingly difficult to locate, particularly those retaining original literature, dealership documentation, ownership history, startup video, and supporting records.

This motorcycle is being offered as a complete, documented survivor and is not being offered for parts.

Purchase & Delivery:

The motorcycle is available for inspection by appointment and local pickup is welcome.

I am willing to discuss reasonable delivery assistance after purchase on a case-by-case basis. As a longtime motorcycle enthusiast and owner, I understand that purchasing a vintage motorcycle often involves more than simply completing a transaction. Reasonable delivery coordination, meeting arrangements, or transportation assistance may be available depending on location and scheduling.

My goal is a straightforward transaction and to see this KTM go to someone who appreciates what it is and will continue preserving it.

Vehicle is sold as-is with no warranty expressed or implied. Inspections are encouraged prior to purchase.
