2022 Harley-Davidson Fat Boy 114 Overview

Harley-Davidson Fat Boy 114 is a custom / cruiser motorcycle, displacing 1868 cc. Power comes from a V2, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 10.5:1. Bore and stroke come in at 102 x 114 mm. On the performance side, it delivers 161.4 Nm @ 3000 Revolutions of torque. On the road, the 2022 Fat Boy 114 tips the scales at 317.1 kg, carries a 18.93-litre fuel tank, offers a seat height of 658 mm and spans a 1666 mm wheelbase. That's roughly 16.5 kg heavier than the average custom / cruiser motorcycle in our database. The full 2022 Harley-Davidson Fat Boy 114 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2022 Fat Boy 114 - Pros & Cons

Strengths

Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Accessible seat height: A 658 mm seat height keeps this manageable for most riders, which helps confidence at parking-lot speeds.
Large fuel range: A 18.93-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
Low-maintenance final drive: Running Belt (final drive) final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Age-related wear: Nothing specific stands out as a weak point on the Fat Boy 114 - the usual used-bike checks (service history, consumables, tyres) apply.

Wear Points & Servicing Notes

Fuelling & injector care

The fuel injection on the Fat Boy 114 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Valve clearance checks

With Double Overhead Cams/Twin Cam (DOHC) valve gear, the Fat Boy 114 needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.

Brake disc and pad wear

Braking up front comes from Double disc. Optional ABS. 4-piston. - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The Fat Boy 114's suspension runs Dual-bending valve 49 mm telescopic with aluminum fork triple clamps; dual rate spring; ´beer can´ covers at the front. The rear uses Hidden, free piston, coil-over monoshock; 43mm stroke; toolless hydraulic preload adjustment. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The Fat Boy 114 runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.

Handling the weight at a standstill

317.1 kg puts the Fat Boy 114 toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.

Fat Boy 114 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2022 Harley-Davidson Fat Boy 114, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy Fat Boy 114 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a Fat Boy 114's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). The sump holds 4.70 litres, so budget for that volume of quality motorcycle-specific engine oil. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the Fat Boy 114 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.

Valve clearance service

Valve clearances are easy to overlook on a used Fat Boy 114 since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
