2018 Harley-Davidson FLHTKL Ultra Limited Low
About the 2018 Harley-Davidson FLHTKL Ultra Limited Low
The 2018 Harley-Davidson FLHTKL Ultra Limited Low is a premium full-dresser touring motorcycle specifically engineered for shorter riders. It features a significantly lower seat height and modified ergonomics compared to the standard Ultra Limited, while retaining the Twin-Cooled Milwaukee-Eight 107 engine. This model year is notable for being part of the early Milwaukee-Eight generation, offering improved heat management and power over previous Twin Cam models.
What Makes This Trim Special
- Lowered Suspension — Front and rear suspension is lowered by 1 inch compared to the standard FLHTK to reduce seat height.
- Reduced Diameter Grips — Smaller diameter hand grips allow for an easier reach to the clutch and brake levers for riders with smaller hands.
- Pulled-Back Handlebars — The handlebars are positioned 2 inches closer to the rider to reduce arm reach.
- Narrow Primary Housing — A slimmer primary drive cover and derby cover provide a straighter leg path to the ground.
- Extended Reach Side Stand — Modified kickstand design makes it easier to deploy and retract with shorter legs.
- Shorter Windshield — A lower profile windshield is standard to improve visibility and reduce buffeting for shorter riders.
Likely but unverified:
- Lack of Heated Grips — Unlike the standard Ultra Limited, the Low model typically lacks heated grips as the reduced-diameter grips were incompatible with the heating elements at production.
