Asphaltfighters Stormbringer | Preview
The Asphaltfighters Stormbringer powered by Warm Up celebrated its superbike world debut at this year’s Essen Motor Show. The claim is that the Asphaltfighters Stormbringer superbike is the world’s fastest street motorcycle.
The new high-performance Asphaltfighters Stormbringer motorcycle has a claimed top speed of more than 199 mph and accelerates from rest to 186 mph in just 13.9 seconds. This performance is made possible by a 1,000-cc four-cylinder four-valve engine with a rated power output of 220 hp / 161.9 kW, which in booster mode can be increased to 280 hp / 206 kW for short periods of time.
While the semi-gloss black/orange Asphaltfighters Stormbringer weighs in at just 429 pounds fully fueled thanks to uncompromising lightweight design, it still combines spectacular design with revolutionary features that have never before been used on a motorcycle. Among them is a backup camera system that eliminates the need for conventional rearview mirrors, a head-up display that projects the current speed onto the windscreen and an innovative lighting system with LED daytime running lights and just one extremely powerful Xenon headlamp that serves as both high and low beam.
The Asphaltfighters Stormbringer is built in small-series production by WARM UP Zweiradtechnik GmbH in Aalen, Germany with an MSRP starting at $57,500 Euros (~$87,000 USD). To achieve the perfect union of high-performance bike and rider the price includes a precision setup of the bike to the rider. Suspension, seating position and all operating controls are calibrated to the rider’s weight and size.
Also included in the price of the bike is high-tech rider gear color-coordinated with the Asphaltfighters Stormbringer. It includes a precisely fitting leather suit and a carbon-fiber and Kevlar helmet whose aerodynamic properties make it perfectly suited for the extremely high speeds this motorcycle can reach.
Engine and Drivetrain
At the heart of the Asphaltfighters STORMBRINGER is the liquid-cooled four-cylinder four-valve engine from engine manufacturer BIKERBOX. Complex detail work by power guru Sepp Buchner results in a rated power output of the 1,000-cc high-speed engine of 220 hp / 161.9 kW at 13,500 rpm.
Realizing this kind of peak power in a reliable manner suitable for everyday use requires enormous effort. The cylinder heads are fitted with a new combustion chamber shape, and inlet and outlet valves as well as the valve seats are optimized for mixture flow. Forged aluminum high-performance pistons are also part of the engine concept as are numerous additional detail modifications to the inner workings of the engine.
Especially important for an explosive power curve are the engine peripherals. Akrapovic is the top choice for the factory teams competing in the Superbike World Championship when it comes to high-performance exhaust systems. As technology partner for the Asphaltfighters STORMBRINGER German Akrapovic importer JAMPARTS supplied a custom-tailored exhaust system with carbon-fiber rear muffler that contributes vitally to the enormous power output of the high-tech engine. The hexagonal shape of the rear muffler makes it also a stunning design feature that blends perfectly with the spectacular overall design.
For an optimal symbiosis of power yield and drivability the engine uses a freely programmable engine management system. Precisely calibrated mapping for injection and ignition ensure a healthy power curve all the way to the cutoff speed of 13,700 rpm. In addition the BIKERBOX engine electronics feature an adjustable ten-stage traction control, a launch control feature for perfect acceleration from rest and a freely programmable speed limiter activated at the push of the button for city traffic or for the pit lane. For especially precise and fast throttle commands the bike features a quick throttle from gilles.tooling.
Perfect lubrication with high safety reserves is elementary for an engine such as the one on the Asphaltfighters® STORMBRINGER. Fully synthetic Bel-Ray EXS 0 W – 40 motor oil combines excellent low-friction properties with maximum wear protection.
Power is transferred to the rear wheel via a high-performance clutch, a six-speed manual transmission and a chain color-coordinated with the overall color scheme. Lubricant specialist Bel-Ray supplies a clear chain spray that provides optimal maintenance while preserving the orange color scheme.
