FAQ
The stock floorboards on a Road King are functional but fairly compact, which limits how much you can shift foot position over a multi-hour ride — a common contributor to the numbness and cramping riders report on long highway stretches. Riders often don't realize how much foot movement matters until they've done a 300+ mile day. Wider, longer rider floorboard inserts with an adjustable position, like NICECNC's kit for the Road King / Street Glide / Road Glide, give more room to shift your feet and reduce fatigue on extended rides.
On long, straight highway miles, staying locked into the same knee angle on the factory floorboards can lead to stiffness in the hips and knees well before a fuel stop is due. Some riders solve this with full engine guards, but that's a bigger investment if you just want an occasional leg stretch. Bolt-on highway engine guard foot pegs, such as NICECNC's foldable set for the Road King / Electra Glide / Street Glide / Ultra Limited, mount forward for a stretched-leg position and fold away when you don't need them.
The stock horn and its bracket sit in a fairly visible spot near the front of the engine, and riders doing a cosmetic cleanup or fairing-lowers install often find it clutters the lines they're trying to clean up. Simply unbolting the horn isn't a complete solution since the mounting bracket is still there. An M8 horn relocation bracket delete kit, such as NICECNC's direct replacement for the factory bracket (OEM #69000083) on Road King and other M8-engine Touring models (2017 and later), lets you remove the horn cleanly using the original mounting bolts.
The factory intake manifold on the M8 engine is sized conservatively for smooth, predictable delivery across a wide range of riders, which leaves some performance on the table for riders who've already upgraded their air intake and exhaust and are looking for the next incremental gain. A one-piece billet intake manifold, like NICECNC's 57mm version for the M8 Road King / Electra Glide / Street Glide platform, is designed to pair with a larger throttle body for improved airflow.
A restrictive stock air filter housing can slightly limit airflow to the engine, and on a heavier touring bike doing sustained highway speeds or slow parade-style riding in traffic, anything that helps intake efficiency is worth a look — though gains from an intake cover alone are modest compared to a full intake and exhaust upgrade. Some riders also want the housing to simply look better under the tank. A chrome LED air filter intake cleaner kit, like NICECNC's version for the Road King / Street Glide / Road Glide platform, addresses the cosmetic side, and pairing it with a proper high-flow filter element is the better move if airflow is the real goal.
A tip-over at a stop sign or in a parking lot is far more common than a highway get-off, and without a front engine guard, that kind of low-speed drop puts the impact directly on the radiator, cases, and bodywork — repairs that can run well past the cost of a guard. Crash bars are as much cheap insurance as they are a styling upgrade. A modular front engine guard, such as NICECNC's crash bar for Road King / Street Glide / Electra Glide, uses replaceable polyurethane frame sliders so a minor tip-over damages an inexpensive slider instead of the bar or the bike itself.
If you're stretching your toe down to catch the shift lever, every shift takes a little more effort and concentration than it should — and at a stop, that split-second of fishing for the lever can throw off your footing right when you need to be solid. A shift lever that sits closer to your boot fixes this directly. Nicecnc's short heel-toe shifter set, about an inch shorter than stock, is a direct bolt-on replacement for '01-and-later Touring and Trike models (OEM 33895-82E) that brings the lever within easy reach so shifts feel natural again — and if you're tall and dealing with the opposite problem, NiceCNC also makes a 1-inch-longer version.
Even garage-kept bikes need a cover that does two things well: actually fit around the saddlebags, and survive being thrown on right after a ride. Generic universal covers are cut for a plain fuel tank and seat line, so on a Touring bike with dual side cases they often bunch up at the bags or leave gaps that let dust and moisture in — not what you want on a bike you're trying to keep garage-clean. And if you cover up while the pipes and mufflers are still warm from riding, a thin cover can scorch or discolor against the exhaust. A cover cut specifically for Harley Touring models with dual side cases, like Nicecnc's protection cover for Road King / Street Glide, solves both: the fit is shaped around the saddlebags instead of draping loose, and a heat-resistant lining near the exhaust area protects the fabric so the cover itself lasts longer.
