Motorcycle Test: Moto Guzzi California Aluminum Special Sport

Moto Guzzi has been through a rough couple of years. In fact, if not for an 11th hour bailout by Aprilia, it's quite likely Moto Guzzi would now reside in that big showroom in the sky. While the infusion of Aprilia's cash and engineering talent promises great things to come, the immediate problem is, or at least was, keeping the name alive and generating some cash flow. To that end Guzzi has upgraded some old standards, one of which, evolved from the California Special Sport series, is now offered as the California Aluminum Special Sport.

Styling wise, the Aluminum is something of a dichotomy. On one hand it's got the swoopy, flowing lines Italians do so well, and on the other, the dull paint and the size of some of the parts it's been applied to, such as the oversized handlebars and risers, conspire to give the bike a distinctly industrial look. The big cylinders poking out from under the tank don't help either -- the matte finish gives them the look of an air compressor. The rest of the ancillary pieces are done up quite nicely. The headlight brackets, for example, are carved from aluminum, the footpeg mounts from aluminum castings. For those who like glitter, a bit of chrome is sprinkled about to add some eye candy. On the chintzy side, there are more plastic-trim pieces than I'd like to see, but at least these are well made and fit properly.

A Handling Fool or a Fool for Handling?

The first clue that the Aluminum is a bit more sporting than your average cruiser is the adjustable, hydraulic steering damper nestled under the left side of the triple clamp. Connected to the damper is a 45mm Marzocchi fork, complete with a bridge-style fork brace. No provisions for adjustment are offered, but none are really needed.

The frame geometry also reflects the Aluminum's sporting, or at least standard, heritage: The rake is 29.5 degrees, the trail 4.25 inches, and the wheelbase 61.4 inches. While these numbers are extremely conservative by current standards, they do lean more toward the sporting side of the road than most cruisers. The rear suspension is a conventional swingarm with dual shocks. Again, there are no damping adjustments, just a spring preload adjuster. The wire-spoked rims, a 2.50X18 front and 3.5X17 rear, require tube-type tires. Our test bike wears a 110/90X18 Metzeler ME33 front sneaker and a 140/80X17 Metzeler ME55A at the rear. Both tires stick like a nailed-on toupee.

Overall, the suspension is compliant without ever becoming mushy. The bike steers easily, is far more maneuverable than the average cruiser and maintains excellent straight-line stability. Handling prowess is nothing without ground clearance, and the Aluminum has it in spades. Even during the most spirited back-road jousting the suspension never loses its composure and none of the hard parts ever hit the deck. The only fly in the handling ointment is the rear suspension, which feels just a tad on the stiff side at times. Whacking a sharp-edged bump usually telegraphs a jolt right to the base of my spine.

Promoting Integration

Normally I'm not a big fan of integrated brakes, especially when they don't have an antilock braking system. In the past, I've found a lot to dislike about Moto Guzzis' linked brakes, particularly when the roads are slippery (and especially when the bike has floorboards). Having said that, I can honestly say the '03 version of the integral brakes are much improved.

The hardware itself is decidedly un-cruiserlike. Up front, dual four-piston Brembo calipers squeeze 320mm floating rotors, with stainless-steel lines tying them together. In the rear, there's a dual-piston Brembo and a fixed 282mm disc. A generation ago brakes this good were cause for comment among the go-faster set, and for a cruiser they are absolutely top-shelf, more than capable of hauling down the 583-pound (dry weight) Aluminum from any speed it's capable of reaching. Both a proportioning and delay valve are incorporated into the brake system. Standing on the brake pedal turns on the rear and left front calipers just like it always has. However, the differential between the two brakes is no longer fixed. Initially, the proportioning valve split the braking force in a 70 percent rear to 30 percent front bias. However, the valve is now load sensitive and adjusts the braking bias to transfer more of the braking force onto the front wheel as required. If you need more whoa, squeezing the front brake lever activates the right front caliper. Rounding a sandy corner under braking,

I felt the front end slip once. Other than that little heart-stopper, the brakes have a solid, linear feel and provide far better feedback than previous versions.

Some New Tricks for an Old Dog

Guzzi's venerable air-cooled 90-degree V-twin has been around almost since the dawn of internal combustion. But that's not to say the old dog hasn't learned a few new tricks, the best of which are hydraulic valve-train lifters and no more routine adjustments or clattery valves.

The rest of the engine also receives some attention. New connecting rods claim to increase performance and reliability, as does a revised lubrication system with oil jets to help cool the pistons. To add a little pizzazz, compression is bumped from 9.5:1 to 9.8:1, a slight but significant increase. Displacing 1064cc and generating a claimed 74 horsepower and 70 foot-pounds of torque, the Aluminum has more than enough poke to keep things entertaining. The bike pulls hard from idle up to about 6500 rpm; after that the mill starts to run out of breath, though it'll twist itself right up to the 8000 redline if you want to thrash it.

The Magneti Marelli sequential fuel injection performs flawlessly, with none of the low-speed, lean surging shenanigans that seem to plague other systems currently in use. Overall, the engine makes decent power, with a nice strong midrange, the kind you need when you're caught daydreaming while your buddy blasts past a car and you have to pin the thing in fifth gear at 3000 rpm to try and keep up.

The '03 engine also seems a bit smoother than its predecessors. This is apparently the result of a redesigned exhaust-system crossover that enhances low and midrange performance.

Unfortunately, the same can't be said of the transmission, which still has a distinctly agricultural feel to it. It also has a tendency to miss gears on occasion, most notably third in both directions. Overall, though, the five-speed box feels pretty robust, and when shifted slowly and deliberately works just fine. Perhaps with some more miles on the bike the shifting will improve. Clutch pull is a bit on the heavy side and gets tiring during stop-and-go riding, though the clutch action is sweet with a broad engagement point.
