1989 Yamaha TZR250 3MA

In the twilight of the 2-stroke era, engineers were desperate to wring every last drop of performance from the parallel twin. While the competition moved to V-twins (Honda NSR, Suzuki RGV), Yamaha took a radically different, almost rebellious approach with the 1989 TZR250 3MA. Tasked by Project Leader Teruo Abe, the factory's GP racing engineers took the YZR500's playbook and turned the engine around—literally. By placing the carburetors at the front and the exhaust pipes exiting out the back of the cylinder head, Yamaha achieved a straight, short intake and exhaust path, maximizing top-end horsepower.

This "reverse cylinder" design wasn't just for show; it was a direct piece of technology taken from the YZR500 GP machines (specifically the 0W48R) to solve the problem of cramped, twisted expansion chambers. The result was a bike that looked unlike anything else on the road, with exhaust ports you could see behind the front wheel and a futuristic, aggressive silhouette. While it was a maintenance nightmare for the average owner, it became a holy grail for enthusiasts who valued engineering insanity over practicality. The 3MA represents the peak of Yamaha's "racer replica" obsession—a bike that was too wild for the street but too beautiful to ignore.

The Bike (Condition)

• Damage disclosure: No visual damages.

• Why this matters: The 3MA is notoriously difficult to restore due to the complex cooling system for the carburetors (to prevent icing) and the fragile nature of the bodywork. Finding a bike that has not been crashed is the #1 priority for any restorer.

• Mechanical status: Runs perfect.

• Other condition notes: The bodywork appears to be original and unmolested. The frame is straight. Please note: due to the reverse cylinder layout, checking the spark plugs requires removing the fuel tank and air box—a tedious process, but a sign this bike has been loved rather than neglected.

Market Comparison (The Opportunity)

We have scoured recent auction results. Clean, restored examples of the 3MA are trading at significant numbers, showing a strong uptick in collector interest for obscure 2-strokes.

What's Included

• One (1) key.

• V5 / Title documents.

• Original tool kit (rare).

• Aftermarket expansion chambers (if applicable, otherwise stock).

Why Bid?

These auction results prove that the barrier to entry for a clean-title, running TZR250 is rapidly approaching $10,000. This particular bike offers a realistic entry point — a complete, running example of a bike that 99% of collectors are afraid to touch. You can ride it now, and restore it later, without the $10k price tag. The Yamaha TZR250 3MA is not just a motorcycle; it is a piece of GP racing history that was road-legal by accident, and this is your chance to own the most technically audacious 250cc bike of the 1980s. Simple math: buy it here for a fraction of the restoration cost. These are going up in value globally, not down. Bid with confidence, knowing that even at this price, you are buying below market.

Sold as-is, where-is. Good luck and happy bidding!
