Falk’s fat falcon

Content of

No, this is not a 1989 GSX-R 1100 that stands out here. But a 2000s Suzuki Hayabusa, fantastically finely transformed by the talented technician and esthete Falk Dirla. The optical illusion is perfect.

NOTDon’t lie! ”PS graphic artist Thomas Waldhauer just wants to hear the truth. "Yes, Thomas, this really is a Suzuki Hayabusa." I can only convince the critical mind with difficulty. Okay, but the three-part fairing of an 89er GSX-R 1100 with the Ram-Air nostrils also leads too easily on the wrong track. And with this wonderfully yellow foiled endurance headlight in the characteristic flat front with double lights, the illusion is even more perfect. But underneath everything is Hayabusa: Motor, chassis, brakes, real GSX 1300. So also the fat light metal bridge frame with the beautiful and stable aluminum swing arm with upper pull. Thomas has an understanding and his aha experience for today is gone.

Falk’s fat falcon

All 16 crooked valves

I had that a few days before, when Falk Dirla smiled and handed me the key to his crouched, sinewy Suzuki Hayabusa. The man is the workshop manager of the Zurich BMW and Suzuki dealer Arrigoni Sport. As a mechanical engineer and two-wheel mechanic master, the Radolfzell knows his trade. At some point he got a wrecked 2000 Hayabusa in his shop, which also had an engine failure: The timing chain had jumped due to a defective tensioner, all 16 valves were crooked, "in four of them the plates even broke," as Falk remembers. Uneconomical repair.

The hawk eventually came back to life

Amazingly, all cylinder liners were in perfect condition, the big block was too good to throw away. So Falk and his apprentice Ivan Ruggle set about rebuilding: "Shrinking 16 new valve guides was very time-consuming." The Suzuki Hayabusa finally came back to life. Unmistakable, but “also ugly as ever,” said Falk on the first test drive when he saw himself in the shop window. An idea came to him: "My career began with the air-cooled GSX-R 750 and 1100, with engine tuning and the installation of six-speed transmissions." Hmm, something has to work … Something worked. 80 working hours later it was completed, the metamorphosis of the most beautiful hunting falcon that ever brushed the asphalt.

The subtleties and finesse lie in the detail

This is evident in the name: GSX-R 1300 instead of GSX 1300 R! The subtleties and finesse are in the details. A subframe of the GSX-R with integrated parts of the Suzuki Hayabusa carries the 1100 fairing that was shot on eBay. Falk changed the front of the tank in favor of a clean look. A harmonious hole had to be made in the fairing on the left, "because a GSX-R carries its alternator piggyback, but the Hayabusa on the crankshaft stub". The high-set series exhausts of the 1300s nestle tightly against the racing hump from Ricambi Weiss. Falk assembled the pipes to the collector from fragments of original parts and heating pipe bends and processed them on a pipe grinder.

Painting is the icing on the cake

What else? The fork bridges were powder-coated and the “Hayabusa” lettering ground away, as was the case on the Tokico six-piston stoppers. Instead, there is now “Brake” in the original Brembo typeface, and “Ohldrin” is emblazoned on the fork. Typography like this is not immediately obvious, but Thomas Waldhauer likes it. Just like the SACS lettering: At Falk Dirla it stands for “Suzuki Advanced Comical System”. Falk also treated the cockpit with shrink varnish and installed a classic MRA screen and subtle mini indicators. Last but not least: the original GSX-R paintwork applied in-house, the history of which is intuitive. Falk’s remarkable time machine was ready. "My Suzuki Hayabusa drives against the clock, and pretty fast," he says with a smile.

From zero to 100 in three seconds

Three seconds for the sprint from zero to 100, almost eight in the last gear from 60 to 140 and even more the top speed of almost 300 km / h can still be seen today. That’s a damn sprightly oldie! From 1,500 turns there is a full boost. Beyond the 8,000 mark, pure anger follows. When you cock the tap, you feel like you’re on a catapult. When the left lane opens, the small rear-view mirrors of the Suzuki Hayabusa are empty of idiotically jostling Audi TDIs in no time. Wipe and away. And all of this served feeling real without ABS and traction control. Even if today’s 1000s go off even faster: This performance, at least 175 hp, makes you relaxed and confident. Power and glory. It’s a shame that Falk himself can benefit so little from it: when the wind pressure starts to support the upper body, from a speed of 120 km / h, the fun stops completely in Switzerland.

Why doesn’t Suzuki build something like this itself?

The grumbling four-cylinder doesn’t have to prove anything, doesn’t have to be loud to sound strong – a gentlemanly athlete. You sit in the machine, perfectly integrated into the action. The Super-Susi drives well and good-naturedly, lies at a travel speed of 250 as if pegged, remains telepathically on (fast) course. On the other hand, it is not quite as nimble in the narrow passages, despite the self-made lever on the strut to raise the rear four centimeters. Ultimately, the Suzuki Hayabusa on the not entirely fresh Michelin Pilot Power 2CT with a flat 50 mm cross-section pulls itself out of the affair considerably. 244 kilos are seven less than standard. Falk’s conclusion: "While others are trying hard to turn a production motorcycle into an important-looking custom bike, I have put a lot of effort into building a custom bike that looks like a production motorcycle." Only one question remains: Why doesn’t Suzuki do this itself?
