The Kalex AV1 comes from Kalex Engineering, based in Germany. It’s the brainchild of two men – Alex Baumgartel and Klaus Hirsekorn – who’ve built this extreme sportsbike that offers all-out performance for the very committed.
The AV1, which weighs a mere 155kg dry, is fitted with a 60-degree, 998cc v-twin from Rotax, with a Motec M800 engine management system. This engine, the V990R (which also powers the Aprilia RSV1000), makes 140 horsepower at 9500rpm, and 107Nm of torque at 7750rpm, which makes for mind-blowing performance in the lightweight AV1. Just as well then, that the engine management system also incorporates an advanced form of traction control software.
The tubular steel trellis frame chassis is light and stiff, and the steering angle is 23.8 degrees, which lets the bike flick from side to side with minimal effort. WP RCMA 4800 USD forks are used at the front, and at the rear there is a WP 4618 monoshock, mated to a specially fabricated aluminum swingarm. Both suspension units are multi-adjustable. Brakes are top-spec Brembo units and the bike rides on 17-inch wheels, with 120/75 (front) and 190/65 (rear) tyres. Carbonfibre has been used extensively, for the bodywork.
Should be interesting to see how it does against a stock R1 or GSX-R1000, eh? Get more details on the Kalex AV1 on their official website here.
