Harley-davidson Dyna Fat Bob

The Harley-davidson Dyna Fat Bob has a top speed of 185 km/h, produces 68 hp and weighs 305 kg. Motoryk rates it 7.8/10.

La Harley-Davidson Dyna Fat Bob (FXDF) a été introduite en 2008 dans le cadre de la famille Dyna, avec une configuration distinctive de deux phares et un garde-boue avant épais qui lui ont conféré une esthétique brute et agressive inspirée des bobbers. Il est rapidement devenu populaire auprès des conducteurs à la recherche d'un look plus musclé et épuré par rapport aux autres modèles Dyna, et a reçu la mise à niveau du moteur Milwaukee-Eight à double refroidissement lorsque Harley a fait la transition entre la gamme Softail et la gamme Dyna en 2018. Le nom Fat Bob a ensuite été intégré à la gamme Softail à partir de 2018 avec un châssis entièrement repensé et un style actualisé.

Ce que les acheteurs doivent savoir

Watch the Twin Cam

The Twin Cam 96/103 engines in 2008-2017 Fat Bobs are known for cam chain tensioner wear — a common and costly issue if ignored. Always verify this has been inspected or upgraded before buying used.

💰

Strong Resale Value

The Fat Bob holds its value exceptionally well compared to other cruisers, often retaining 70-80% of its value after 3 years. Its aggressive dual-headlight styling keeps demand consistently high in the used market.

Milwaukee-Eight Upgrade

2018+ Fat Bobs switched to the Milwaukee-Eight 107 engine, a significantly more reliable and smoother platform with improved oil cooling and reduced vibration. Buyers should strongly prioritize this generation over earlier models.

"Un meurtrier d'apparence méchante qui se comporte mieux que prévu."

Le Fat Bob est le châssis Dyna qui donne le meilleur de lui-même : cette Twin Cam 96 montée sur caoutchouc tire fort dès 2 500 tr/min et le large pneu avant à 180 sections confère à l'ensemble de la moto une sensation de stabilité et de détermination que les fans de Softail n'ont jamais ressentie. J'ai parcouru 500 miles par jour et la selle surbaissée de 686 mm est vraiment confortable pour un pilote de taille moyenne, même si les deux phares sont plus esthétiques que l'éclairage nocturne réel. Leur faible intensité est embarrassante par rapport aux normes modernes. Le moteur en panne et la posture brute du bobber vieillissent étonnamment bien, mais à 302 kg mouillés, vous pouvez sentir chaque kilo lors des manœuvres lentes sur les parkings et la suspension d'origine est réglée pour quelqu'un qui ne pèse rien et ne heurte aucune bosse. Les vibrations transmises par les repose-pieds au-dessus de 100 km/h sont réelles et constantes, ce qui fait partie du charme ou vous rend lentement fou, selon votre personnalité.

Pros

+Couple de serrage puissant et utilisable à bas régime
+Meilleure tenue de route : le style Dyna
+Esthétique de bobber agressive et intemporelle
+Étonnamment confortable lors des longues journées
+Assistance après-vente approfondie pour Harley

Les inconvénients

Phares d'origine dangereusement inadéquats
Lourd et maladroit à basse vitesse
Suspension souple, fond sur les bosses
Vibrations persistantes des repose-pieds sur l'autoroute
Idéal pour: Les conducteurs de Urban Cruiser veulent de l'attitude Ignorez si: Vous donnez la priorité au sport ou au tourisme

7.8/10
Idéal pour
Experienced riders wanting authentic V-twin character daily

"Raw, honest American muscle that rewards careful used-buying diligence."

$7,500-$14,000 used

The Fat Bob is one of Dyna's most characterful machines — that wide 21-inch front wheel and dual headlights give it a genuinely menacing street presence that ages well. The Twin Cam 96 or 103 engine is bulletproof if it's been maintained, and most Fat Bobs have seen decent miles without drama. Check the cam chain tensioners on pre-2006 bikes though — that's the one known Achilles heel that can turn into an expensive rebuild if ignored. Riding position is aggressive for a Harley, feet forward but not stupidly so, and the thing actually handles reasonably well for something this heavy. Don't expect sporting dynamics, but it won't embarrass you on twisty roads either. Vibration through the pegs is real above 70mph — that's not a fault, that's a Dyna. Budget for new tires almost immediately on anything used, and inspect the rear isolator mounts religiously. They crack silently and the handling goes sideways fast.
