2015 Harley-Davidson FLHTCUL Electra Glide Ultra Classic Low
About the 2015 Harley-Davidson FLHTCUL Electra Glide Ultra Classic Low
The 2015 FLHTCUL is a specialized 'Low' version of the standard Electra Glide Ultra Classic, specifically engineered for riders under 5'7". It features the lowest seat height in the premium touring segment for its year, achieved through lowered suspension and ergonomic adjustments. As a Project RUSHMORE model, it benefits from significant 2014-era upgrades including the High Output Twin Cam 103 engine, Reflex linked ABS brakes, and the Batwing fairing with Splitstream venting.
What Makes This Trim Special
- Lowered Suspension — Front and rear suspension lowered by 1 inch compared to the standard FLHTCU.
- Narrow Profile Primary — Shaved primary housing and derby cover to allow for a straighter leg path to the ground.
- Reduced Reach Handlebars — Handlebars are pulled back 2 inches closer to the rider than standard touring bars.
- Smaller Diameter Grips — Reduced diameter hand grips to accommodate smaller hands.
- Low-Profile Seat — A specialized seat that is both lower and narrower at the nose to reduce reach.
- Extended Jiffy Stand — A longer toe tab on the kickstand to make it easier to reach and retract.
