In a notable reveal for motorcycle enthusiasts, Harley-Davidson has confirmed that the largest stock engine available in a production motorcycle for 2026 will be its 121 cubic inch Milwaukee-Eight V-Twin. This engine powers several models within Harley’s lineup, including the premium Street Glide Limited, which retails at $51,999—substantially higher than competing touring motorcycles like the Honda Gold Wing and Yamaha FJR.
Although the Street Glide Limited exudes a classic design reminiscent of the 1950s, the Milwaukee-Eight V-Twin boasts modern engineering features such as variable valve timing and electronic fuel injection. The engine produces a robust output of 115 horsepower and generates 139 lb-ft of torque.
Größer als die Konkurrenz?
In a competitive landscape, Indian Motorcycles is vying for the attention and dollars of American riders with its flagship model, the Indian Pursuit Elite. While the Indian’s engine is smaller at 112 cubic inches, it exceeds the Harley in horsepower with 126 hp, though it falls slightly behind in torque at 133 lb-ft. Priced at $44,999, the Pursuit remains a premium option, albeit less expensive than the Harley.
In comparison, the Honda Gold Wing, which features a unique 1,833 cc (111 CI) boxer engine, offers a performance of 125 horsepower, positioning it slightly above the Harley in terms of output. The most expensive Gold Wing variant, equipped with an automatic transmission and airbag, retails for $33,800, excluding a destination charge of $775.
Thus, Harley-Davidson’s 121 cubic inch V-Twin is not only the largest engine within its own product lineup, but it is likely the largest among cruiser and touring motorcycles as a whole. However, this analysis reveals that while Harley leads in size, Indian holds the advantage in performance metrics within the high-end touring segment.
