Cycle magazine said the 1978 RM125 was the most powerful 125cc motocross that had ever tested, putting out 22.08 horsepower and 12.24 foot-pounds of torque.

This example is VIN: RM12574693.

There is no odometer, true mileage is unknown.

This bike is being sold by our friends at New Haven Powersports in New Haven, Connecticut. “The early history and exact provenance of this machine are currently unknown, it has been on display in their showroom since the early 2000s. This is a used vintage motocross bike that is a classic “10-footer.” It boasts a striking, nostalgic silhouette that catches the eye and photographs well, but closer inspection reveals weathered details, patina, and mechanical wear. It is an older aesthetic restoration with a driver-quality cosmetic finish that runs well.”

Maintenance:
There are no maintenance records.”

Mechanical Issues:
The fuel tank does not hold gasoline. The bike runs great.”

Modifications:
Per the seller, this bike is stock but was cosmetically restored years ago.

Inside of the tank:

It is riding on Michelin Starcross/Cross Competition M12 tires that have aged out.

Cosmetic Blemishes: please see the album in the “Photos” tab for all known cosmetic blemishes. Here is a selection:
The fuel tank decals are bubbled/raised in areas and cracked in some also.

The center frame lower OEM decal is peeling.

The silencer is dented and the swing arm metal is pitted.

It features an older cosmetic refurbishment that presents very well from a distance, making it a great candidate for a garage display or a vintage rider project. The bike has been fully painted, showing a vibrant aesthetic from afar, though closer inspection reveals a typical driver-quality finish with minor overspray and wear consistent with age.
