The group has been in the business of customizing Milwaukee-made machines for nearly 20 years, and they sure didn’t waste any time: the sheer number of custom motorcycles they made during this time is huge, and depending on what custom parts are used, each of their bikes is part of a distinct category.
The modified Street Bob in the gallery above is part of a collection the group calls MBT. It is one of the most heavily modified machines Thunderbike ever made, featuring a list of custom parts so long it’s hard to see what hardware of the original Harley is left.
Mechanically, the bike, officially called Red Wheel MBT, is packing a Screamin’ Eagle Stage IV kit, thanks to which the displacement of the engine has been increased from 107ci to 114ci. At the front, a new fork that works exclusively with an air-ride suspension has been fitted, and there’s a pulley brake kit on the custom Thunderbike wheels.
Visually, there are few few parts that have been left untouched. The turn signals, grips, fuel tank, headlamp, fenders, and the exhaust are all aftermarket parts meant to make the motorcycle look and feel completely different than its original self.
Contributing to that is the color scheme chosen for the various parts of the body, of course. There’s red on the wheels and strategically placed parts, black on the mechanical bits, and silver on the tank and fender.
The bike has been built a while back at the request for one of Thunderbike’s customers and is a one-off.
