Custom bikes often feature few Harley parts, and that's definitely the case with this wild Dragster.
Little Harley
In the world of custom bikes, we often refer to them as Harley-Davidsons, but in many cases, there isn't much Harley going on at all. That's certainly the case with this Dragster build from Thunderbike, dubbed RS-O. In fact, the only Harley parts present on this wicked-looking machine are the engine and transmission, but that doesn't make it less cool by any means.

Solid Base
Like many of the German builder's creations, RS-O is riding on the outfit's Dragster RS frame, which is long, low, and quite sleek in appearance. The frame is part of a complete kit, which is constructed from steel tubing and CNC-milled sides. Rounding out the kit is an oil and fuel tank, aluminum swingarm with battery holder, rear section, rear-wheel axle, motor bracket, and seat plate.

All Thunderbike
From there, Thunderbike added its own matching RS fork and swingarm, foot pegs, rear brakes and discs, and a set of sweet looking "Vegas Cut" wheels that measure in at 4.4x18-inches up front and 10x18-inches in the rear. The tires come from Metzeler and measure in at 130/60 and 280/35 front and rear, respectively.

Air It Up
Tricky Air provided the air suspension, which most bikes of this ilk are typically fitted with. After all, this kind of setup allows owners to drop the bike on the ground for show purposes, then air it up for actual riding. Because who wants to scrape up that precious paintwork on some crappy roads?

H-D Mill
The drivetrain for this particular custom is all Harley, however. It starts with a 103-inch Screamin' Eagle powerplant, which provides ample power to the giant rear tire via H-D's five-speed transmission. The mill breathes in through a Screamin' Eagle air cleaner and out through Thunderbike's Dragpipes exhaust.

Look the Part
Despite its wild nature, this particular build is covered in a rather traditional orange hue, albeit with some checkered flag graphics and black accents. The paint job, as is typically the case with Thunderbike's creations, was handled by Kruse Design, and it did a fantastic job as always.

Define Custom
Long, low, and mean-looking, RS-O certainly fits the bill as a bike that's equally good at show and go. And even though its only actual Harley parts are what motivates it, that's nothing unusual in the world of custom bikes. After all, that's what the word "custom" means, right?
