Lot 12628: 2022 Harley-Davidson FXBBS

A Stage 1 upgrade for your 2022 Harley-Davidson Street Bob 114 is the classic “bolton” setup that focuses on improving airflow through the engine for better power and sound. For your Milwaukee-Eight 114, the best Stage 1 mods are:

The Core Trio (All Work Together)

1. High-Flow Air Cleaner – Replaces the restrictive stock intake with something like the Screamin’ Eagle Heavy Breather or an S&S Cleaner. Lets that big 114cc engine breathe better.

2. Aftermarket Exhaust – Most Street Bob owners go with slip-on mufflers (easier install) or a 2-into-1 full system for more punch. The 2-into-2 offset shotgun pipes on your bike already sound great, but aftermarket cans or a shorty setup really let you hear that Milwaukee-Eight rumble.

3. Fuel Tuner / ECU Flash – Critical! The stock fuel map won’t compensate for the increased airflow. You’ll need a tuner like the Power Vision, FP3, or a proper dyno tune to richen up the mixture and avoid running lean.

What You’ll Get

• 5-10% more horsepower and torque
• Much crisper throttle response
• That signature deep Harley bark we all love

Budget

Expect to spend anywhere from $500 to $1,500+ depending on the brands you choose. Most folks end up around $800-$1,200 for a solid setup from Screamin’ Eagle, Vance & Hines, or S&S Cycle.

Worth noting—your Street Bob’s already a torque monster with 119 ft-lbs on tap, so Stage 1 is really about waking up that feel and the sound. If you want bigger numbers, Stage 2 with a cam upgrade is where things get spicy!
