2020 Softail Low Rider - Pros & Cons

Strengths

Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Strong front braking: Stopping power up front is strong thanks to the disc setup, with plenty of room to upgrade further with braided lines.
Accessible seat height: A 690 mm seat height keeps this manageable for most riders, which helps confidence at parking-lot speeds.
Large fuel range: An 18.9-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
Low-maintenance final drive: Running a belt 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 Softail Low Rider - the usual used-bike checks (service history, consumables, tyres) apply.

Wear Points & Servicing Notes

Heat management in traffic

Because the Softail Low Rider 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 Softail Low Rider needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Brake disc and pad wear

Braking up front comes from 2 x disc, 4 piston caliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The Softail Low Rider's suspension runs Showa Inverted forks at the front. The rear uses Mono Shock. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The Softail Low Rider 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

300 kg puts the Softail Low Rider 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.

Softail Low Rider - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2020 Harley-Davidson Softail Low Rider with its 1746 cc custom / cruiser, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs belt final drive, so check belt tension and tooth wear - a cracked or glazed belt is a clear sign of neglect. Now 6 years old, this custom / cruiser is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy Softail Low Rider should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects the Softail Low Rider's 1746 cc four stroke, v-twin, milwaukee-eight 107, pushrod-operated, overhead valves with hydraulic, self-adjusting lifters, 4 valves per cylinder like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 10.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the Softail Low Rider 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.
