Aprilia revealed the new SRV 850, one of the biggest scooters on the planet. It’s powered by a 90-degree V-twin with a claimed 76 horsepower, more than with many motorcycles, and Aprilia claims a top speed over 120 mph. Larger-than-normal 16 and 15-inch wheels front and rear roll over road irregularities with greater ease than the ones on smaller scooters.
