The 1948 Harley-Davidson S-125 sold for $6,800, which is strong money for a collector piece in this condition and rarity.

This S-125 is a slice of motorcycle history. With its 125cc two-stroke single engine and three-speed transmission, it represents Harley’s post-war innovation. The bike is freshly restored, sporting a semi-gloss black finish and a striking silver girder fork that catch the eye. At just 1 mile shown on the odometer, it’s practically untouched since its refurbishment. That level of mileage, albeit marked as “TMU” (True Mileage Unknown), adds to its appeal as a collector’s item. The left-side kick starter is a nod to classic design, making it attractive for those who appreciate vintage motorcycles.

The bidding was quite active, with 25 bids placed, showing significant interest in this model. Given the extensive restoration and its unique traits, the sale price of $6,800 feels justified. Prices for similar models can vary widely, but considering the rarity and condition, this was a fair outcome—especially for a bike that’s been so thoroughly refreshed.

The community reacted positively, with one user congratulating the buyer, @fletcham, on the win, indicating that there’s respect for the purchase within the community.

For buyers looking for a similar bike, pay attention to restoration quality and originality. Verify that the modifications enhance rather than detract from the bike's value. Check for documentation of the restoration work done, as it can significantly affect desirability and price.
