2018 Ultra Limited - Pros & Cons

Strengths

Accessible seat height: At Unladen 740 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.

Considerations

Age-related wear: As with any used Ultra Limited, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.

Owner Experiences & Common Issues

Low-speed confidence

At 413 kg, the Ultra Limited is a substantial machine. New owners occasionally mention that slow-speed manoeuvring in car parks takes a little getting used to. Once moving, the weight disappears - but practising slow-speed exercises builds confidence quickly.

Ultra Limited - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2018 Harley-Davidson Ultra Limited, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained Ultra Limited should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any Ultra Limited. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
