On the performance side, it delivers 105 hp @ 4600 rpm of peak power and 176 Nm @ 3250 rpm of torque. On the road, the 2025 Street Glide Ultra tips the scales at 377 kg and carries a 22.7-litre fuel tank. That's roughly 52.9 kg heavier than the average touring motorcycle in our database. The full 2025 Harley-Davidson Street Glide Ultra spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2025 Street Glide Ultra - Pros & Cons

Strengths

Strong power output: With 105 hp @ 4600 rpm and 176 Nm @ 3250 rpm of torque on tap, the Street Glide Ultra is no slouch for its class.
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Large fuel range: A 22.7-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
Low-maintenance final drive: Running Belt, 32/68 ratio final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Age-related wear: Nothing specific stands out as a weak point on the Street Glide Ultra - the usual used-bike checks (service history, consumables, tyres) apply.

Wear Points & Servicing Notes

Heat management in traffic

Because the Street Glide Ultra relies on airflow rather than a coolant jacket, expect noticeably more radiant heat at low speed and in traffic. It's inherent to air cooling, and ventilated gear largely offsets it.

Fuelling & injector care

The Electronic sequential port fuel injection (ESPFI) on the Street Glide Ultra needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Final drive maintenance

The Street Glide Ultra runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.

Handling the weight at a standstill

377 kg puts the Street Glide Ultra toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.

Street Glide Ultra - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2025 Harley-Davidson Street Glide Ultra, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy Street Glide Ultra should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a Street Glide Ultra's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the Street Glide Ultra needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
