Used Harley-Davidson Low Rider ST 117: Market values, best years, and buying guide
The 2026 Low Rider ST is not a pure Touring bike; it is a "Sport-Touring" model based on the Softail frame with the Milwaukee-Eight 117 engine. It is designed for higher lean angles and more aggressive dynamics. This sporty character means that components are subject to different stresses compared to heavier models.
1. M8 117 Management and Performance
The 117 in this configuration is punchier, but heat management is critical due to the saddlebags that partially limit airflow and the "Mini-Batwing" fairing.
Tester’s Tip: The stock "Heavy Breather" air filter is very exposed. If you frequently ride on dusty roads, the throttle body gets dirty much faster than on other models. Clean the throttle body and MAP sensor every 8,000 km.
Technical Secret: The 117 on the ST tends to transfer significant heat to the seat and the rider's legs. Ensure that the rubber gaskets around the engine are intact: if damaged, heat from the crankcase will rise directly toward the rider.
2. Chassis: The Importance of the Monoshock
The ST has a rear suspension with longer travel and a stiffer setup.
Secret: The preload adjuster (under the left side cover) is the heart of this bike's dynamics. If you feel it "squatting" on corner exit, increase the preload by 2-3 clicks. Many owners ignore this setting: a properly preloaded ST changes its dynamic behavior radically.
Tip: Unlike the Road Glide, the ST’s fork is heavily stressed under braking. If you notice excessive "diving," don't swap fork oil for a thicker grade (you risk damaging the SDBV valves); upgrade to springs with a higher spring rate (e.g., Andreani kits or similar).
3. Transmission: The Weak Link of Sporty Use
The Low Rider ST invites rapid shifting and hard braking.
Critical Point: The mainshaft bearing is stressed by sporty riding. Never perform "violent downshifts" (over-revving). The M8 117 has a lot of torque, and the clutch can suffer thermal stress if not modulated well.
Tip: Change the primary oil strictly every 8,000 km. The ST’s primary chain works under constant load, and the oil degrades rapidly due to the "spirited" riding this bike inspires.
4. Electronics and "Ghost Faults"
Tip: The ST shares the Touring CAN-bus system but is less isolated from vibrations. If ABS warning lights or irregular lights appear, check the connectors under the seat. The 117’s vibrations can loosen thinner connectors over time. A quick spray of electrical contact cleaner whenever you remove the seat is a good habit.
5. Braking: The Essential Upgrade
The Low Rider ST features dual front discs.
Secret: The stock brake pads are calibrated for "touring" use. If you want to unlock the ST’s potential in the mountains, install high-performance sintered brake pads. The difference in bite is clear and protects the ABS system from unnecessarily long activation cycles.
Chronic Critical Points (What to watch)
Fairing Bolts: The frame-mounted fairing vibrates significantly. Check every 5,000 km that the mounting screws to the triple tree are tight. If they loosen, the vibration can create micro-cracks in the supports.
Belt Tension: On the ST, due to the swingarm geometry and shorter wheelbase, the belt works more aggressively. Check it often: an over-tightened belt on this bike causes noticeable vibrations on the passenger pegs.
The Crazywheels Tester’s Opinion
"The 2026 Low Rider ST is the most fun Harley in the lineup. But it is a bike that requires 'active maintenance.' It’s not a bike to leave in the garage waiting for service intervals. It is a machine that should be checked before and after every sporty weekend. If you learn to adjust the preload and maintain the primary, the ST will give you sensations that no other Harley can. If you are looking for a 'turn-key' bike that needs zero attention, the ST is not the right choice."
