Requirements Harley-Davidson Road: The Harley-Davidson Road Glide and Indian Challenger stand out as key players in the premium touring motorcycle market. Both bikes target riders between 35-60 years old, who value comfort and performance for long journeys. Still, their maintenance needs are quite different, which can sway a buyer’s choice.
Harley-Davidson: Key Details
The Harley-Davidson Road Glide packs a Milwaukee-Eight 117 V-twin engine, delivering a solid 125 ft-lb of torque.
On the flip side, the Indian Challenger comes equipped with the PowerPlus 108 cubic-inch (1,768cc) liquid-cooled V-twin engine, generating 122 ft-lb of torque at 3,800 RPM. This minor torque difference might not be noticeable during regular rides, but it could influence performance in specific situations.
Both motorcycles need oil changes every 5,000 miles, using synthetic oil as recommended by their manufacturers. This common maintenance schedule makes ownership easier for those considering either bike.
However, the Indian Challenger adds a maintenance task due to its liquid-cooling system, which requires coolant flushes every two years or 24,000 miles. In contrast, the Harley-Davidson Road Glide, with its air/oil cooling system, doesn’t need those flushes, resulting in a simpler maintenance routine.
Both models use belt final drive systems, requiring tension inspections every 5,000 miles. Since they both share this requirement, neither bike has a clear edge in this maintenance aspect.
When it comes to pricing, the Road Glide typically starts around $24,999, while the Indian Challenger usually retails for about $22,999. While these figures might change for 2026, they provide a general idea of what to expect.
