The look is older than Honda itself. The elegant, flowing curves and clean detailing on Honda's latest cruiser stretch back to pre-war years. In the 1930s, what we would now call "high-tech" design took its inspiration from the evolving science of aerodynamics. Smoothly rounded designs pioneered on aircraft were applied to cars, trains, appliances, and motorcycles. Luxury automobiles developed long, low, teardrop contours. The style spoke of elegance, comfort and speed.
The motorcycle beneath the retro styling of Honda's Aero is very similar to the extremely popular Shadow A.C.E. (American Classic Edition). It uses a similar chassis, and power comes from the same liquid-cooled 1099cc 45-degree single-crankpin V-twin engine. However, the Aero has a longer, lower appearance and a host of unique styling touches that immediately distinguish it. The wheelbase stretches an additional 1.1 inches to 66.1 inches, and full fenders, a long, classically shaped 4.2-gallon fuel tank, and fat whitewall tires accentuate the bike's length. But the sense of expanse is probably heightened most by the long two-into-one exhaust system, with a fat single muffler that draws your eye back past the rear fender, where it culminates it a subtle fishtail.
No Japanese bike has ever...
No Japanese bike has ever come from the factory with a fishtail muffler before, and few bikes of any ilk can boast such an ear-pleasing exhaust note. Long and fat, the muffler not only looks and sounds good, it leaves room for saddlebags and contributes a substantial power increase compared to the A.C.E., which has an otherwise identical engine.
The Aero is the first Honda ever to wear rider floorboards, and these polished-alloy items lay almost flat to contribute to the impression of length. The low, saddle-style seat and short-rise, pullback handlebar further accentuate the Aero's length. Another essential component of the look is the stretched chrome headlight, which houses the speedometer. Honda has never felt that speedometers belong down out of view on the fuel tank, but setting them atop the fork crown (like the Spirit or A.C.E.) interrupts the lines of a cruiser. So, as with the first bikes it imported into this country, Honda dropped it into the headlight shell. The elegant ivory-faced instrument features nostalgic, yet readable numerals. Operated electrically, it has no cable to clutter the bike, but the LCD odometer/tripmeter (which all new designs now get because they are small, light and hard to tamper with) sounds a slightly discordant note.
Viewed from above, the Aero also looks fairly wide (though it's no Suzuki Intruder 1500). The beefy fenders, wide saddle and big gas tank promise a broad, comfortable mount. The 33.2-inch-wide handlebar spreads outward from its mount, then turns back at its ends, for a sort of mild beach-cruiser bend. The rider's position is a bit like sitting in a desk chair, with your feel almost flat on the footboards, instead of the more heels-low angle adopted by most other floorboards. The relationship of the seat and handlebar permits average-sized riders to adopt whatever position they prefer, leaned-back, hunched forward or bolt-upright. We admit to being slightly surprised that the wide handlebar and turned-back grip angle didn't load our arms more heavily at high speed. You had to counter a bit more pressure and grip slightly harder than on the other 1100s, but it didn't become a major comfort issue at high speeds.
Identical to the A.C.E. except...
Identical to the A.C.E. except for two internal transmission ratios, the Aero engine makes more power thanks to its large muffler and multiplies that with gearing to run away from the other two Shadow 1100s in top gear.
Though splendid around town, our two-day ride with the bike prompted modest complaints from all riders about the floorboard position. Though we were divided on whether they were too high or too flat, everyone wished they were somehow different on long rides. Others also wished for more room to scoot backward on the saddle. Though it's not plushly padded, the saddle is wide enough--almost 16 inches--and shaped so that two or three hours didn't leave us saddle sore. Passengers get a comfortable position, but the removable passenger pad is unexceptional and, in our experience, will cause annoying noises to develop behind you on longer, two-up jaunts.
That pretty well sums up our complaints about the way the Aero rides. We sort of expected to be whining about vibration here before we rode the bike. Unlike the offset-crankpin design of the Spirit, which can be designed to cancel most of a 45-degree V-twin's vibration, the single-crankpin layout usually means that the engine shakes. That's true of the Aero, but its rubber engine mounts and other factors limit how much vibration reaches the rider. You can feel some vibration at any speed. At highway speeds, you feel some shake through the floorboards (more on the right than the left), though some vibration gets soaked up by the floating design of the pad where your feet rests. At more aggressive highway speeds, the tank borders on discomfort if you press your legs against it firmly. The buzz through the handgrips is subdued and objects in the mirrors are recognizable below 80 mph or so. The saddle only shivers uncomfortably at high rpm, such as during hard acceleration. For the most part, vibration rarely asserts itself.
Besides putting the speedometer...
Besides putting the speedometer up where you can see it, the Aero also locates its warning lights atop the triple clamp, where they can catch your eye. The black button on the triple clamp is the tripmeter reset button.
Honda did an excellent job of choosing suspension rates, and the ride is firm but rarely harsh. Only large, sharp-edged bumps jolt you, mostly through the rear end. Rolling bumps slip under you with less violence than most other machines. And the effective damping selections make the bike steadfast when braking hard, dipping into switchbacks on a mountain road or dodging errant drivers in the city. Because the floorboards are fairly flat and they taper down at their rear (which might normally drag first), you can lean the Aero over more than most floorboard-equipped bikes before things get noisy and the boards start to fold up. Though its extra length and weight mean that it can't respond to steering inputs as readily as the A.C.E., the Aero feels just as comfortable when heeled into a corner and even steadier when you confront crosswinds and road irregularities. It also remains manageable and well balanced when tip-toeing through a tight spot.
The Aero uses an engine that, except for the first- and fifth-gear ratios, is identical to the Shadow A.C.E., which is relatively slow for an 1100. Honda had said that the Aero makes about five more horsepower thanks to its exhaust system design, but since it also weighs over 40 pounds more we expected to be a bit underwhelmed by the engine performance. We were therefore surprised when the Aero pulled away not only from the A.C.E. but also the Spirit in top-gear roll-ons. The difference is shorter gearing in the Aero's fifth-gear ratio. The Aero's top-gear ratio, which is .8:1 compared to the .76:1 of the A.C.E. combined with the added power, gives it a larger edge than we'd expect. All other intermediate ratios and rear tire sizes are the same. The extra rpm compared to both the A.C.E. and Spirit gives the Aero the best top-gear giddy-up of any of the 1100 Shadows. Most of our highway passes of slower traffic were conducted in top gear, yet the Shadow retro-rocket feels and sounds relaxed on the highway.
Fat whitewall tires and deeply...
Fat whitewall tires and deeply valenced fenders help set the nostalgic tone of the Aero's design. However, the twin-piston front brake offers modern braking performance by increasing the brake pad area brought to bear on the disc.
The Aero sounds like a hot rod. The deep-throated blat emanating from the exhaust system should come from a bigger motorcycle. Throttle response is crisp and precise with no lean spots or hesitation anywhere. The engine feels more willing when you open the throttle than the A.C.E., and power swells steadily from just off idle to the horsepower peak just below 5000 rpm. The only payback comes in fuel economy. At an average of 35.1 mpg, the Aero's fuel mileage was consistently worse than the other three 1100s along on the same ride. But we had no other engine-related grumbles. It starts readily, often without choke, and warms promptly. There is adequate off-idle power and flywheel effect to get rolling smoothly with little clutch slipping.
The wet clutch offers a light pull and progressive engagement. Only one rider ever experienced any shifting problems, but his style is to upshift with his toe rather than the heel portion of the lever on floorboard-equipped bikes. Some lever adjustment probably would have ended his occasionally balked first-to-second gear change. We had no complaints about lash or shaft-induced jacking.
With a twin-piston caliper up front and those wide tires, you can coax some pretty respectable hard stops out of the Aero with little fade. Control is good at both ends, and the long wheelbase and controlled suspension take some of the excitement out of panic stops.
The Aero is the first Honda...
The Aero is the first Honda with rider floorboards. Tapered at the rear to allow more lean angle before they drag, the floorboards fold up when they do touch down. An acorn nut on the underside is the first thing to grind. The rubber pad mounts on a steel insert, which floats inside the polished aluminum floorboard frame to soak up some vibration before it reaches the rider.
Of course, the major issue for this motorcycle is its ultra-retro looks. Few details disturb the almost flawless execution of the look. You get the typically excellent paint produced by Honda's facility in Marysville, Ohio, and deep, smooth chrome completes the sense quality. A clear plastic lens enhances the multi-reflector headlight's retro appearance. Chrome heat shields give the header pipes a beefy appearance that matches the rest of the system and the bike. Chrome fender rails seem to have sprung from the era that the designers sought to evoke, even though the front ones are purely cosmetic. The rear of the tank matches the width of the seat. Chomed covers and polished fin edges complete the engine, and Honda offers optional chrome trim to dress up the radiator. The handlebar switch housings, master cylinder and fork crown are polished. The as-cast rear-wheel drive housing is one of the few unfinished pieces on the bike. One of our biggest cosmetic complaints was grease thrown out from the rear wheel which stained the rear white wall.
Cleaning the two-inch-wide whitewalls will be one of few chores the Aero owner must attend to. Checking the uniquely shaped (and therefore probably expensive) battery under the left side panel is easy. The air filter is under the saddle, and easy to remove for cleaning or replacement. Though the bike needs to be upright when checking oil, you can reach the dipstick from the saddle, so one person can do it. A spin-on filter resides under the engine. Self-adjusting valves and cam chain mean there is little else to do to keep your engine fresh and healthy. A flat tire would be a problem, as on most cruisers with wire wheels, and removing the rear wheel requires that the muffler come off.
Honda provided a guard rail...
Honda provided a guard rail to keep helmets attached to the lock from getting scuffed on the tire. The guard makes a good perch for bungee cords, which can also be hooked under the fender rail. The chrome on the fender rails is flawless.
We expect to quickly see plenty of aftermarket support for the Aero, with a few A.C.E. accessories that fit it too. Honda has a windshield, radiator guard, back rest, luggage rack, extensions for both fenders and leather saddlebags. We anticipate a long list of aftermarket offerings by year's end.
At first blush, adding one more Shadow 1100 to its line, especially when it already has the most popular metric cruiser in the country, seemed like a strange thing for Honda to do. But after you have looked at and ridden the Aero, it makes perfect sense. Taking a giant step back into the past and large step forward in performance, it moves away from all offerings in the 1100cc range. Its looks alone should lure thousands of potential buyers, and those who bite aren't likely to be disappointed.
