Aprilia SL 750 Shiver 2010 — Specifications

What drives a manufacturer to revise a motorcycle that sells poorly, when the product itself is not to blame? That is exactly the question raised by the 2010 version of the Aprilia SL 750 Shiver, revised with measured restraint to win over a market that turns its back on it without good reason. The modifications remain cosmetic and ergonomic: petal discs, a revised handlebar, a seat lowered by 5 mm to 810 mm, redesigned air scoops, and a riding position shifted slightly further forward. The rear footpegs, however, betray an accounting exercise rather than a styling one. What truly catches the eye are the new aggressive color schemes and the assertive fork brace framing the headlight unit: the Shiver stops keeping a low profile.

The twin-cylinder 750 cc roadster segment is not exactly crowded. Ducati broke new ground with the Monster 750, without ever sparking mass enthusiasm. Aprilia arrives with a far more argument-laden proposition, amid competition that includes the Honda Hornet, the Kawasaki Z 750, and a few Monsters of larger displacement. For the Aprilia SL 750 Shiver, the battle will not be won on brand recognition but on raw engineering.

And that is precisely where the SL 750 scores points. Its 90° L-twin, with a bore of 92 mm and a stroke of 56.4 mm, produces 95 horsepower at 9,000 rpm and 80.9 Nm of torque at 7,000 rpm. For context: an SV 650 of the era tops out at 74 horsepower, a Monster 800 S2R at 77. Aprilia delivers a figure here that looks the Ducati 748 — a pure sportbike — squarely in the eye. Better still, this engine features ride-by-wire, technology at the time reserved for Yamaha's R6 and R1. Four valves per cylinder, dual ignition, dual overhead camshafts, liquid cooling: the spec sheet reads like that of a supersport dressed in civilian clothes.

The question of how much an Aprilia SL 750 Shiver weighs comes up often, and the answer tempers enthusiasm slightly: 210 kg fully fueled, 189 kg dry. It is no featherweight, but it is within segment norms. The steel tubular trellis frame, connected to two aluminum plates, supports a 43 mm inverted fork with 130 mm of travel and a rear monoshock of equal amplitude. The radially mounted front calipers bite two 320 mm discs — equipment still found in Grand Prix racing a decade prior. At €7,799 at launch, the price is consistent with its ambitions.

Finding a used Aprilia SL 750 Shiver today means getting your hands on an unjustly forgotten motorcycle. It speaks to an intermediate rider who wants character without breaking the bank, technology without the compromises of a true sportbike, and a design unlike anything else in the garage. Its main flaw remains the lack of commercial visibility that Aprilia never managed to correct. But on the road, once the engine is up to temperature and the gears are engaged, the verdict is unambiguous: Noale built something serious.
