Aprilia finally revitalizes its Shiver naked and Dorsoduro big supermoto motorcycle platform as announced at the EICMA bike show in northern Italy. Both the 2017 Shiver 900 and 2017 Dorsoduro 900 get a larger displacement V-Twin engine (897cc), new suspension, and modern styling cues.
Specifically, piston stroke has increased from 56.4mm to 67.4mm broadening the powerband. Aprilia rates the engine’s power (as measured from the crank) at 95.2 hp at 8750 rpm and 59 lb-ft at at 6500 rpm. For reference the last time we measured the Shiver 750’s power output on the dyno it recorded 46.54 lb-ft and 76.63 hp.
The original Shiver was the the first production Aprilia to feature ride-by-wire throttle connection. Since, the Italian’s have spent years perfecting the technology on other models, including the Tuono 1100, and the new setup powering both 900’s should be better than ever. Both models offer three engine power mode map selection (Sport, Touring, and Rain) so you can tailor the engine’s powerband to your liking.
The system now integrates three-way adjustable (plus off) traction control— yet another area of electronic expertise that Aprilia excels at with its modern RSV4 sportbike platform. Keeping tabs on machine vitals is a new color display that can automatically dim, or brighten, based on environmental conditions. An accessory Bluetooth-enabled kit allows you to link the motorcycle to your smartphone Aprilia says.
They roll roll on a hybrid chassis that employs a steel-trellis-type front half bolted to a pair of aluminum spars. The shock attaches directly between the frame and the swingarm without a linkage. Typically, this simpler arrangement allows for more rear end feel at the cost of plush bump-absorbing ride quality.
Up front, a Kayaba inverted fork replaces the 750’s Showa component. The six-spoke wheels are new and over four pounds lighter than the old rims. Surprisingly, the cast alloys are wrapped with Dunlop’s more budget-minded Sportmax Qualifier tires rather than sourcing nationally-branded rubber from Pirelli.
Triple disc brakes from Brembo are standard as is ABS, and the braking system benefits from a high-quality and fade-resistant stainless-steel brake lines. No official word on whether these motorcycles are coming Stateside, but considering its engine size, and where it slots into the American market, we expect to see it in Aprilia dealerships next summer.
