The buying public will probably make the final determination on the flexibility of the Mana; one thing’s for sure, this bike is unconventional, at least in the sporting realm.
We’ll get into the usual stuff in a minute, but first let’s look at what makes this Italian Twin, running around Europe last year and finally hitting the U.S., so unique.
The clutch lever is gone and is replaced by an electronic control system. The sequential gearshift can be operated by a simple handlebar control as well as by the traditional foot-operated shift lever. This isn’t so new to the two-wheeled world; recall that Yamaha made electronic shifting part of its line-up two years ago with the YCC-S (Yamaha Chip Controlled-Shifting) on the FJR1300AE. What is unique is that in auto mode, the tranny is essentially a CVT setup. If the rider doesn’t shift manually (when decelerating), the control system intervenes to automatically downshift.
Aprilia does well in combining this tech with more tech. The “Sportgear” transmission can be operated in seven-speed manual shifting mode, or electronically in Autodrive with three engine mappings: Touring, Sport, and Rain. These three mappings are most likely the same as on Aprilia’s SL750 Shiver and are not unlike the premise behind the A-B-C settings of Suzuki’s S-DMS (Suzuki-Drive Mode Selector) found now on all of its GSX-R line.
The rider decides when to change gear, either using the conventional shifter or a switch on the handlebars. A servo mechanism shifts the main pulley to change between the seven gear ratios. During deceleration, if the rider doesn’t shift manually, the control system intervenes to change down automatically, preventing engine speed from dropping below the set threshold.

The 16-liter (4.2 U.S. gal.) tank is located under the seat to distribute weight more evenly and lower the bike’s center of gravity. Again, not ground braking, as BMW’s F800ST and F650 also fuel under the saddle. The traditional tank location is occupied instead by an illuminated storage compartment that is lined with non-slip, non-scratch material and is big enough to house a full-face helmet. The compartment also incorporates mobile phone storage and a 12V power socket.
The vehicle documents and toolkit are also located inside the same compartment, as are the battery and fuses. The faux fuel tank storage compartment is opened electrically by a switch on the handlebars. The lid opens under the control of a hydropneumatic damper that prevents accidental opening while the bike is in motion. A manually operated lever under the passenger seat is provided to release the compartment lid in the event of a flat battery.
The Mana’s liquid-cooled, eight-valve, SOHC, 90-degree V-Twin engine has an oversquare bore and stroke of 88 x 69mm displacing just over 839cc and squeezing the fuel mixture induced via Weber-Marelli EFI with a single 38mm throttle at a compression ratio of 10.0:1. Claimed output is 76 horsepower at 8,000 rpm and 54 ft-lbs at 5,000 rpm, all at the crank. Aprilia anticipates the Mana will get over 40 mpg in city driving. And the whole thing is E3 compliant thanks also to the 2-into-1 stainless steel exhaust that houses a three-way catalytic converter. This mill is “the perfect partner for this type of transmission,” according to Aprilia materials.
The 850 Mana’s tubular-steel trellis frame uses the engine as a stressed member and a linkage-less offset monoshock with preload and rebound adjustments connects the aluminum swingarm. Front suspension is a 43mm USD fork, apparently unadjustable. Braking is handled by a pair of radially-mounted four-pot calipers pinching 320mm floating rotors, and a single-piston clamp squeezes a 260mm disk in back; both are carried on 17-inch wheels. We suspect the brake package was snatched right from the SL750 Shiver.
