Further improving an Aprilia RSV4 Factory APRC is a very ambitious project. Dominik Klein does not shy away from it – luckily.

The Tuner-GP 2012 showed it in several PS editions: Some tuners really worked hard. Like Dominik Klein, who did not roll a Yamaha out of his van for the first time. Over the last few years he has impressively demonstrated that he has always outdone himself on Tuner GP projects. But an Aprilia R.Improving SV4 Factory APRC is not only difficult, it is a Herculean task even with an experienced tuner.

Black V4 Thunder


Black matt and fast. Black mamba, black widow or black beauty, all names fit perfectly.

The chassis matches the powerful engine 100 percent, and the feedback from the RSV4 is more than direct thanks to the K-Tech chassis and Dunlop slicks. The bike rides, figuratively speaking, as if on rails. As soon as I think of a new line, it already follows the slightest steering impulse. Even with the most unreasonable drifts, there is never any unrest in the chassis. The RSV4 shows itself to be extremely strong not only when exiting a curve, but also at the entrance: the brakes always stay snappy and stable, the ingenious feeling for the front wheel ensures infinite trust and fuels the desire for hard infights.

The best thing about Dominik Klein’s tuning is the fact that nothing interferes with driving. Everything works perfectly and unobtrusively. How does he get that? He always sees the overall concept and therefore takes care of all the details. It starts with the engine electronics. Because “you can do a lot better there”, as Dominik reveals with a smile. Ergo, he simply modified the entire wiring harness and implanted a rapid bike racing module that changes almost all relevant values ​​of the eight injectors and the ignition. Corridors are programmed for this, which optimize the combustion and thus the performance depending on the selected gear, driving condition and lambda value.

Increased performance thanks to know-how. Tuner Dominik Klein optimized the engine peripherals and the electronics of the Aprilia RSV4. Your engine remained unopened and will therefore last a long time. A guarantee of fun: The extra power is noticeably available over the entire speed range.

While driving, this device constantly learns and readjusts all values ​​in the ranges described. Then Dominik rebuilt the oil circuit so that he can save the fan without thermal overload. Other victims of the radical diet were batteries, exhaust systems, chains, panels, screws and much more. Even the original gearshift was thrown out. Instead, a Quick-Shifter from Tellert came to the Aprilia. Shorter ignition interruption times and – much more important – checking whether the gait is correctly positioned using gait travel sensors are the arguments in favor of castling.

The light carbon cladding, many titanium screws and a lot more help to keep the weight down to 194.5 kilos. As already mentioned, the original landing gear will be replaced by British K-Tech components. Specifically: at the front, a super bike KTR 2 fork is in IMA Racing triple clamps, at the rear the Italian is supported on a 35 DDS shock absorber. A BKG 2D handlebar improves the racing posture, while the finest Brembo GP4-RX pliers bite into fat T-Drive discs at the lower end of the fork. A radial 20 mm Magura manual fitting completes the brake.

In order to keep such a valuable bullet properly on track, super glue from Dunlop found its way onto the forged wheels. The only criticism you could make is the 17-inch front wheel. To further facilitate quick corner changes, the small Aprilia would look good on a 16.5-inch front wheel with a 125/80-420 slick.

When I talk to Dominik Klein about it, he just grins knowingly and waves it away: “Sure, I had thought about that too. But that’s how you assemble street pelts, change a few little things and the Aprilia is approved! ”This V4 weapon approved? Wow, even I’m speechless for a long moment.
