Homemade motorcycle with Aston Martin V12

"Test drive where? We’d better stay right here, around the clinic. Then you haven’t got that far. Test drive with the conversion of an Aston Martin Springfield V12.

Oh yes, I added these supports to the frame. They allow an incline of almost 30 degrees. Should the buck tip over, it will not fall completely on its side" Or does it? I am sceptical. How compliant is tar? Because the buck, as its builder Frank Ohle calls it, weighs 700 kilograms. Maybe 750. It doesn’t matter, a hundredweight more or less doesn’t matter here anyway. So again: If the goat tips over, when turning, climbing or parking, then the 14 or 15 quintals lean on the tar with a jerky surface the size of a matchbox. And if this does not give way, the stand will stop at an angle of about 30 degrees. You then only need to straighten it up again. It’s that simple. That simple.

Flashback: A video has been roaming the Internet for a year now showing a self-built bike with an Aston Martin V12 engine. The Wuppertal machinist Frank Ohle has changed the chassis of a Boss Hoss, squeezed in the powerful six-liter engine of an Aston Martin DB7 and occasionally takes his 435-hp monster for a walk. After a short message in MOTORRAD 8/2011 Ohle invited to the driving appointment. You can’t miss something like that; the situation is extremely unfavorable. Thick banks of clouds in all shades of gray cover the evening sun, you can literally smell the rain. We are on the premises of Ohle’s employer in Wuppertal-Elberfeld, and despite
dI am relieved by raw wetness and fading brains. Although this monster, with its total length of three meters and a 2.33-meter wheelbase, is the mightiest I have ever come across, I had imagined its builder differently.

Always good for a surprise: designer Frank Ohle (49) from Wuppertal.

Photographer Rossen Gargolov and I follow the duo in the car. Frank Ohle doesn’t take the easiest way out of town by God. Over narrow paths and small villages it goes towards Bergisches Land. Windows are closed, pedestrians salute, dogs freeze. All faces have one thing in common: the open mouth. There is an infernal rumble through two narrow side pipes, because the expressions of life of six full displacement liters flow into a twelve-in-almost-nothing exhaust system. Frank drives easily, swings through curves, goes into an inclined position. Please go. Fifteen minutes later: A drizzle is cleaning the floor, Ohle stops on a narrow path, dismounts, hits my shoulder and whispers: "Now is driving! There’s a parking lot back there, so you can easily turn around."Turn loosely. I would be more comfortable if I could easily fold up the side stand. Because the seat is low, but also quite wide at 420 millimeters. 700 kilos want to be balanced. With the right foot. The one on the left tries to flip up the side stand. Sweat. Even now. Damn. Flip up the side stand. Reach for the ignition key. Both toes on the floor. The automatic transmission has three gears: a gear that goes up to around 200 km / h, an overdrive that is geared up to around 300 km / h, and a reverse gear to be able to maneuver the monster better. Starts in idle. It shakes, twelve pistons whiz through their homes. Five liters of gear oil swirl through the converter, twelve liters of coolant flow through the ducts, ten liters of engine oil force its way through the bearings, lubricate and cool. The Big Block is 80 centimeters wide, 100 centimeters long, and weighs 300 kilograms without attachments. This drive spreads my legs sparingly, I feel helpless, completely at the mercy. Because my hands grip the one-meter sail pole, steering requests are carried to the bike somewhere in front via two huge aluminum risers and an eternally long fork. That reminds me of the game "silent post". I feel like a foreign body that will never merge into one with this motorcycle. Unless you go up in flames together. The front tire doesn’t tell me where it’s going, and the drive probably doesn’t tell me when the 556 Newton meters simply overwhelm the 300 slipper.

Think! The colossus starts moving in a surprisingly soft and controlled manner, we roll straight ahead. The parking lot is in sight. Tarred, slightly sloping, 100 meters long, around 20 meters wide. Turning is a disaster. Because I am too timid, roll too slowly and incline the chunk slightly. Bad mistake. At the top, your hands cramp on the handlebars, your feet paddle along at the bottom, and in the middle, 700 kilos push towards gravity. In addition, while the back slipper is still emotionally rolling in the center of the Wuppertal district, the one in front thinks it is already in the Mettmann district. Turned. Soaked in sweat, it goes back to a T-junction, the left turn works without any problems. Suddenly two dog owners are strolling across the street. You don’t need a horn here. This is done by turning the throttle. The buck also has no tachometer. On what feels like 1000 tours, you rumble along the country road at 80 km / h and feel like Munchausen riding a cannonball. The converter converts the power humanely, the fear of an uncontrolled spinning rear wheel is unfounded. That gives courage and the respect melts. Let’s see what‘s up, I think. And suddenly tighten the gas rope. Big boost? Think! The wheel is spinning, the road is soaking wet, the chunk barely moves. Slightly slowing down the gas, finally grip. We’re shooting forward. A mass, gigantic, indefinable. Fork feedback – hardly available. Brakes – easily overwhelmed. I think less about driving and more about survival. Wide arches are not a problem. But I am extremely afraid of turns. V12, 700 kilos – how did you come up with such a crazy idea?

700 kilograms, 556 Newton meters, 435 hp, 300 mm roller, drizzle – if I had been careful at school, that would not have happened.

Frank Ohle is a die-hard biker. Five of his current eight motorcycles are registered. The man, nicknamed Iron Face, got bored on his boss Hoss. His plan to plant a V12 in the Hoss chassis paid off when he got hold of an Aston Martin drive via E-Bay. Had V12 blocks from Audi, VW or BMW "optically not turned on." The reprogramming of the electronic engine control and the flange-mounting of the Boss-Hoss transmission on the V12 caused headaches. "Against these challenges, the framework change was a children’s birthday party." Space had to be created for the huge drive. The two upper cables are screwed on and can be removed to change the spark plugs. Is allowed "Buck" Unfortunately not. There is an emissions report from Aston Martin, but on the sound "you have to do it again
to do something." Frank is a freak. His V12 is now too boring for him. A new project is haunted in his head, even wilder, even crazier. That’s why the Zwolfer is also for sale. VB: 76,500 euros.

As the landscape glides past me, I wonder who could use such a bike. "It is also ideal as an eye-catcher or advertising medium for trade fairs and shop windows", says Frank. Correct. Hardly anything is more conspicuous. Darkness colors the horizon. I’ll be back in the editorial office tomorrow and the world has changed. Maybe I’ll never again denounce the clumsy steering behavior of a Harley Sportster 48 that rolls over a 150 mm slipper at the front. Because everything is relative. Not just fear.
