Today, we’ll be diving in for a thorough analysis of a staggering custom exploit brewed by a German artist. The project in question was crafted by an ambitious moto master named Mathias Wiese, who completed the meticulous customization process back in 2019. His venture revolves around a 1976 variant from Honda’s mighty CB550 range, and it does a fantastic job at demonstrating Wiese’s abilities!

The donor motorcycle is brought to life by a four-stroke inline-four powerplant with two valves per cylinder head and a displacement of 544 cc. This strong piece of air-cooled machinery will be more than happy to deliver as much as 50 hp at 8,500 rpm, while a solid torque output of up to 32 pound-feet (43 Nm) will be produced at approximately 7,400 revs.

A five-speed gearbox channels the engine’s oomph to the rear 18-inch wheel by means of a chain final drive. Ultimately, this state of affairs leads to a healthy top speed of 114 mph (183 kph). All things considered, it’s quite safe to say this bad boy is a force to be reckoned with.

Wiese kicked things off by treating CB550’s inline-four fiend to a selection of modern components that’ll have it perform like an absolute gem. Those include larger pistons, a Yoshi camshaft, a fresh clutch basket, as well as a CB650’s crankshaft and cylinders. Furthermore, the mill breathes a little more freely, thanks to a set of Keihin CR29 carburetors that wear velocity stacks.

As a result of the aforementioned tweaks, the air-cooled creature was blessed with a redline of no less than 10,500 rpm, while CB550’s top speed was increased to a generous 125 mph (201 kph). In terms of aesthetics, you will find an aftermarket fuel tank that looks the part, complemented by a tiny front fairing and a bespoke tail section.

Additionally, Mathias installed a pair of custom fenders and replaced the stock lighting items with state-of-the-art alternatives. At the front, the suspension setup was honored with top-shelf inverted forks, joined by dual Koni shock absorbers and a new swingarm on the opposite end. Finally, the bodywork was enveloped in a metallic blue finish with silver accents on the gas tank.
