High Dollar Machine

While there are plenty of budget builds out there in the world, the vast majority of custom Harley-Davidson bikes emerging from shops around the globe are of the higher-dollar variety, without a doubt. After all, buying a new Harley isn't a cheap endeavor to begin with, and customizing one to the hilt can cost even more. However, few builds we've seen in recent history are quite as extensive - and pricey - as this custom Fat Boy from Thunderbike dubbed GT-Leader.

Injecting Sportiness

The list of modifications present on this Fat Boy is a rather long one, though almost every single component fitted to the cruiser comes from the confines of Thunderbike itself. Overall, the idea was to infuse a bit of sportiness into the muscular machine, and in that vein, a set of GT wheels help out in a big way - and also inspired this build's name, too.

Up Front

Aside from that upgrade, this Fat Boy features a lowered telescopic fork up front, along with a 300mm floating disc brake, a "Hollywood" headlight, satin black grips, LED turn signals, and a skinny front tire mounted to the 21-inch GT wheel.

Blacked Out

Moving rearward, we get a good look at the black quilted single seat, a lowered stance that comes courtesy of an air ride suspension, an oval air box air filter with a matching cover, a custom ignition cover, polished pulleys, and a host of black components ranging from the footrests to the tank mount to the Dr. Jekill & Hyde exhaust system.

Full Catalog

Things wrap up in the rear with a super-fat 260-series tire that gives this Fat Boy a pro street-style appearance, along with a newly-relocated license plate frame. Overall, it's quite a stunning yet simple machine to look at, and truthfully, most would have a hard time telling that this cool custom is the result of a full catalog of parts being thrown at it - not to mention money.
