Modified Honda CBX750F Is Between Restomod and Custom, Looks Infinitely Better Than Stock

Working on cars and motorcycles is undoubtedly one of the best ways to bond with your father, and some will even go on to turn it into a flourishing family business. Enter Michael and Allen Posenauer, the talented father-and-son duo behind AMP Motorcycles over in Germany. The two have been building custom bikes together for many years, and every project they came up with thus far has been extraordinary.

Some were featured right here on autoevolution in the past, but it will always be a joy to go back and see what these guys are getting up to. Even their older builds are worth inspecting in close detail, because Michael and his son have long been at the very top of their game! Take, for instance, the svelte Honda CBX750F shown above this paragraph, which does a wonderful job at demonstrating what AMP is all about.

Built back in 2020, the bike retains a large chunk of the CBX750F’s original character, but it improves upon it in several ways. As most of you will probably agree, the end result is a thrilling sight to behold, mainly due to the huge drop in visual mass at the back. Few would venture to call a stock CBX750 stunning or even remotely pretty, yet this particular exemplar is a different story altogether.

And despite the model being one of Honda’s commercial failures, it did offer a fairly solid mechanical basis for AMP to work with. Its power source is an air-cooled 747cc inline-four with 16 valves, capable of mustering a very respectable 93 ponies and 53 pound-feet (71 Nm) of torque. Coupled with a six-speed gearbox, it allows the CBX750 to hit speeds of up to 131 mph (211 kph) when pushed to the limit.

Technical specs aside, the Posenauers kicked things off with a 1986 model from Honda’s lineup, provided by an eager client along with very few instructions on how they should proceed. Delighted to have free reign over most of the future mods, the AMP duo dragged the donor into their shop, took it apart, and wasted no time digging in.

For starters, the customer asked them to keep the conventional OEM forks, partially due to budget constraints but with the primary intent of retaining the retro aesthetic. Thus, AMP’s specialists simply had them rebuilt and filled up with fresh oil, subsequently turning their attention to the rear end. Mind you, things got a lot more interesting in that area.

Michael and Allen did away with the motorcycle’s factory monoshock, so as to make room for a modern and way more capable Wilbers alternative. They also refurbished the brakes for improved stopping power at both ends, while wrapping the stock CBX750F wheels in a grippy pair of Metzeler Lasertec tires. All the mods mentioned so far are undeniably effective, but the bodywork department is where the real party’s at.

Choosing to keep the standard belly pan, fuel tank cover, and front fairing, AMP focused mostly on the southernmost section. Gone is all the massive rear-end equipment once worn by this machine, and the setup fitted in its stead completely changes the bike’s overall appearance. First, the Germans fashioned an all-new subframe to replace the original unit, encasing it in bespoke aluminum side panels thereafter.

Up top, you’ll see a stylish solo seat upholstered in Alcantara, complete with a red upper edge nicely color-matched to the motorcycle’s livery. Flanked by tiny aftermarket turn signals, the handmade saddle fronts a sharp aluminum tail section with LED lighting integrated at the back. Furthermore, there’s a compact lithium-ion battery hidden well out of sight behind the side covers.

It’s connected to a custom wiring harness just like all the other electronic goodies, without a single loose wire visible anywhere on this specimen. Rounding out the bodywork adjustments is a small, yet effective front fender, while most of the hardware in the cockpit area is still stock. The last major changes took place in the powertrain sector, where some new breathing equipment ensures ample airflow.

On the intake side of things, the CBX750’s airbox was eliminated in favor of aftermarket pod filters, and these are appropriately complemented by revised exhaust plumbing. Although the factory headers are still in play, they’ve been skillfully reshaped as a four-into one configuration and then capped off with a slim race-spec muffler. With the exhaust system looking the way they wanted, AMP’s artisans were happy to call it a day.

Their striking Honda CBX750F is really more of a restomod rather than a fully-fledged custom, beautifully showcasing what can be accomplished with just a few thoughtful modifications. It’s a matter of subtraction instead of addition, and the Posenauers knocked it straight out of the ballpark! We never thought a CBX750 could look this good and are glad to have been proven wrong.
