Benelli TREK TRE-K 1130 2006-2017 Service Manual

Motorcycle News' own review confirms exactly why this bike stands out in Benelli's lineup: big Benellis have rasping inline-three engines, and the TRE-K is no different — its 1,130cc motor is shared with the Café Racer, TNT, and Tornado, but retuned here specifically for genuine mid-range usability rather than outright top-end thrills. That same review praises the beautifully made tubular steel frame and swingarm, plus quality standard equipment: Marzocchi forks, Brembo brakes, and an Extreme Tech rear shock.

Power comes from a 1,130cc liquid-cooled DOHC inline-three, an 88mm x 62mm bore and stroke, an 11.9:1 compression ratio, delivering a claimed 123 hp at 9,000 rpm and roughly 115 Nm (85 lb-ft) of torque at 6,250 rpm through a 6-speed transmission with a wet multi-disc clutch and chain final drive, reaching a genuine top speed around 224 km/h (139 mph). The bike is structurally derived directly from the Tornado Naked Tre (TNT), sharing that model's fundamental engine and tubular frame architecture.

A genuine Amazonas variant joined the range from 2007 onward, built specifically to tackle any type of terrain and road — small side fairings, wire-spoke wheels with off-road tires, and a three-into-one exhaust with the muffler mounted under the seat, while sharing the exact same 123 hp engine tune as the standard road-focused model. Confirmed factory specs list a 50mm Marzocchi inverted telescopic fork offering 150mm of travel, paired with an adjustable Sachs shock at the rear delivering 144mm, dual 320mm front discs with 4-piston calipers, and a single 240mm rear disc with 2-piston calipers, riding on Dunlop D270 tires (120/70-17 front, 180/55-17 rear).

Confirmed dimensions list an 810mm (32-inch) seat height, a 1,514mm wheelbase, a 25-degree rake with 109mm of trail, and a 22-litre fuel tank with a further 4-litre reserve. Genuine optional accessories offered across this range included carbon fiber mufflers, mudguards, belly pans, and chain casings, plus a dry clutch kit and semi-rigid panniers. 2006 UK launch pricing was £8,349.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2006-2017 TRE-K 1130 running the way it was built to.
