Aprilia

It's been a while since we last checked in with Aprilia's flagship RSV4 superbike, but a fresh version has just dropped that takes this absolute weapon of a thing to new heights: 1100cc, 217 horsepower and a top speed around 305 km/h (190 mph).

Powered by the front half of a Tuono 1100 V4, the Aprilia Concept RS660 unveiled at EICMA is a lightweight parallel twin supersport bike with comfy ergonomics for the road and a frontal aerodynamic profile that changes angle to adjust the balance between drag and downforce.

The shape of future sports motorcycles evolved considerably over the last few days as the world's leading sportsbike manufacturers and MotoGP contenders evaluated new aerodynamic fairings at the second last test of the MotoGP pre-season at the Chang International Circuit at Buriram, Thailand.

This year the Autumn Stafford Sale seemed more eccentric than normal, with some extraordinary motorcycles selling for not very much, and at the other end of the scale, several of the most expensive two-stroke motorcycles ever sold at auction.

The new Aprilia Shiver announced at EICMA last November is now for sale featuring the same 900 cc engine (up from 750 cc), advanced traction control, redesigned exhaust, and new chassis.​

RM Sotheby's Duemila Route Auction contained 423 cars, 150 motorcycles, 60 boats and racing hydrofoils, 117 bicycles, bobsleds, and more. Here's the highlights of the motorcycle section.

Control is the key word in the new Aprilia RSV4s and Tuonos, and the result is near limitless adjustments over nearly every aspect of these bikes, many of them on the fly.​

It's silly season in Milan, with manufacturers jostling for the spotlight with a cavalcade of new bikes, model updates and wacky prototype concepts at the 2014 EICMA motorcycle expo. Here's our favorite new bike highlights from one of the biggest motorcycle shows on the global calendar.

The first round of the World Superbike Championships was held at Phillip Island on the weekend with strong indications that the 2014 championship will be won on one of five bikes: Aprilia RSV4, Kawasaki ZX-10R, Ducati Panigale, Suzuki GSX-R1000 or a Honda CBR1000RR.

The scooter and motorcycle are morphing into a new form with the power, braking and roadholding of the motorcycle, and carrying capacity, protection, comfort and ease-of-use of the scooter.

The convergence of the car and the motorcycle we forecast last year looks set to continue with the first public showing today at EICMA 2010 in Milan of a range of three and four wheeled scooters by Italian start-up Quadro.

There were many wonderous things at this year's Intermot Motorcycle Show, but few will capture your imagination as much as this home-made Ducati V8.
