Bulgarian firm Vilner Studio is best known for creating one-of-a-kind designs for car interiors but the tuner has also dabbled in motorcycle design. In its latest two-wheeled project, Vilner gives the 2010 Aprilia Tuono 1000 a makeover, producing what it calls the Aprilia Stingray.

2015 Hero Hastur 620cc Streetfighter Concept Revealed – Video
Hero Motocorp has revealed a new 620cc streetfighter concept called the Hastur at the 2014 Indian Auto Expo in Greater Noida, near New Delhi.
The Hero Hastur concept was developed with the help of Erik Buell Racing which provided its expertise in working with larger engines than Hero’s usual small-displacement motorcycles. The Hastur is powered by a parallel twin 620cc engine claiming 78.9 hp at 8000 rpm and 53.1 ft-lb. at 7750 rpm. Claiming a wet weight of 352.7 pounds, Hero says the Hastur can reach a top speed of 149 mph and has a 0-100 kph time (0-62 mph) of 3.8 seconds.

The engine uses a counter-rotating crankshaft, much like MV Agusta’s three-cylinder models. In theory, the counter-rotation should improve handling by reducing the engine’s gyroscopic forces. Power is transferred to the rear wheel through a six-speed transmission.
The chassis consists of a yellow steel trellis frame and an aluminum subframe that supports the seat and tail. The swingarm is a steel trellis design that matches the frame, and uses an adjustable monoshock, while up front, the Hastur uses an adjustable 43mm upside-down fork (Hero doesn’t specify exactly what is adjustable in the front or rear suspension.)
The cast aluminum wheels are stopped by dual four-piston calipers up front and a single-piston caliper at the rear. Pirelli suplies the Diablo Rosso II tires.
Other features include a TFT speedometer, projector beam headlights with LED running lights, turn signals and taillight, 4-gallon fuel tank, bar-end mirrors and underslung exhaust.
At the moment, the Hastur is still classified as a concept, but with Hero’s plan to expand into developed markets like the U.S., expect Hero to eventually put this middleweight streetfighter into production.
