The available manufacturer data verifies two 2026 U.S. V-twin motorcycles above 100 hp: the Harley-Davidson Sportster S at $15,999+ and the Indian 101 Scout at $16,999 MSRP. That is not enough evidence to name either the cheapest qualifying bike or to rank the 10 cheapest. The comparison below makes the scope explicit and identifies the lower-priced models that still need horsepower verification.
Verified 2026 U.S. models above 100 hp
These are two confirmed examples, not a complete market ranking. Prices are manufacturer starting prices, not guaranteed out-the-door totals.
| Model | Published power | Starting price | Price basis |
|---|---|---|---|
| Harley-Davidson Sportster S | 121 hp; 93 lb-ft of torque | $15,999+ | 2026 U.S. manufacturer listing; see Harley-Davidson’s Sportster S page. |
| Indian 101 Scout | 111 hp; more than 82 ft-lb of torque | $16,999 MSRP | 2026 U.S. MSRP. Excludes destination and handling, tax, title, license, and registration; dealer prices may vary. See Indian’s 101 Scout page. |
Why this is not a list of the 10 cheapest
A verified pair cannot establish which bikes are the cheapest across the market. A ranking needs a complete candidate set and comparable prices, alongside model-specific evidence that each motorcycle clears the 100-hp threshold.
Some lower-priced models are worth checking, but their horsepower is not established by the available manufacturer lineup information. Harley-Davidson lists the 2026 Street Bob from $14,999+, Super Glide from $15,999+, and Low Rider S from $18,999+ on its 2026 cruiser lineup; the lineup does not verify that these models exceed 100 hp. Indian lists the 2026 Scout Bobber from $12,999 and Sport Scout from $13,499 on its 2026 lineup, but that listing excerpt likewise does not establish their horsepower. Their lower listed prices make checking their individual specifications important before comparing them with the confirmed bikes.

What counts as a fair comparison
The title leaves several choices open, and each can change the result. A defensible “cheapest” ranking should state whether it covers U.S. or another market, which model years it includes, and whether it compares new motorcycles or used listings. It should also define “cruiser”: the Sportster S is in Harley-Davidson’s Sport lineup, so including it treats sport-cruisers as part of the category.
- Power: Confirm published horsepower for the exact model and year, rather than inferring it from engine size or family name.
- Price: Compare the same type of figure, such as manufacturer starting MSRP, and disclose whether destination, setup, taxes, registration, and dealer charges are included.
- Ranking: Include only models with verified power above 100 hp and a stated, comparable price basis. If prices are only starting MSRPs, describe the result as an MSRP comparison, not an out-the-door ranking.
What the confirmed prices mean when shopping
The Sportster S’s listed starting price is $15,999+, while the 101 Scout’s listed MSRP is $16,999. Those figures show the manufacturer-listed starting prices for these specific 2026 U.S. models; they do not establish what a dealer will charge or the final amount paid. Indian explicitly excludes several purchase costs from its MSRP and notes that dealer prices may vary. Harley-Davidson’s listing is also a starting price, so request a written local quote before comparing actual purchase totals.
