Aprilia’s middleweight ADV twin blends rally-influenced hardware with modern rider aids in a package aimed at riders who split time between asphalt and dirt. This Aprilia Tuareg 660 review focuses on real-world usability and how the 2026 Aprilia Tuareg 660 specs stack up for enthusiasts comparing options in the class.
The 659 cc parallel twin delivers a healthy 80 hp at 9,250 rpm and 70 Nm at 6,500 rpm, striking a sweet spot for an ADV that has to hustle highway miles yet stay manageable off-road. With a 13.5:1 compression ratio and 81.0 mm x 63.93 mm bore and stroke, it feels eager to rev without sacrificing tractability. Around town, the electronic fuel injection with Ride‑by‑Wire keeps responses smooth, while the multiplate wet clutch with slipper function calms downshifts on tight backroads or descending dirt.
On the open road, the 6‑speed transmission and chain final drive (15/42) make it easy to stay in the torque zone for passing. Off-pavement, the twin’s midrange torque lets you modulate traction precisely, supported by APRC aids when conditions deteriorate. Efficiency is solid too, with a WMTC figure of 4.0 L/100 km (58.8 mpg US) and Euro 5+ compliance.
Aprilia builds the Tuareg 660 around a steel tube frame with aluminum engine plates and geometry aimed at agility and stability: a 26.7° rake, 113.3 mm trail, and a 1525 mm (60.0 in) wheelbase. The 21 x 2.15 in spoked front and 18 x 4.25 in spoked rear wheels (90/90‑21 and 150/70‑18 tires) bias the bike toward confident off-road manners, aided by serious suspension travel and ground clearance.
The KYB 43 mm USD fork is fully adjustable with 240 mm of travel, matched by a fully adjustable KYB monoshock also offering 240 mm. With 240 mm (9.5 in) of ground clearance, you can roll through ruts and rocks that trouble street-biased ADVs. The Aprilia Tuareg 660 seat height is 860 mm (33.9 in), which will feel natural for taller riders and manageable for average-height riders with proper technique. At parking-lot speeds, the Aprilia Tuareg 660 weight of 204 kg (449 lb) is noticeable, but the slim chassis and supportive electronics help keep low-speed maneuvers composed.
Braking is handled by quality hardware: dual 300 mm front discs with Brembo calipers and ABS, plus a 260 mm rear disc with Brembo caliper. Cornering ABS with 3 maps brings extra confidence on mixed surfaces. Aprilia’s APRC suite includes ATC, AEB, and AEM, accompanied by 4 ride modes to suit changing terrain and a Cruise Control (ACC) for longer slogs.
Suspension is a highlight: fully adjustable KYB components front and rear, each with 240 mm of travel. The wheel and tire combo (21/18 spoked) underscores the bike’s dirt credibility, yet remains road-capable. You also get a 5‑inch TFT display, full LED lighting with perimeter DRL, and an 18 L (4.8 gal) fuel tank with a 3 L reserve to stretch those outback days. Other essentials include liquid cooling, a 6‑speed gearbox, and a chain final drive, all wrapped in a sturdy frame designed to take hits.
The Tuareg 660 fits riders who want a genuinely off-road-ready middleweight that remains comfortable cruising to the trailhead. Experienced riders will appreciate the long-travel suspension, electronics suite, and 21/18 wheels. Confident intermediates can grow into it thanks to smooth fueling and manageable torque delivery. True beginners may find the 860 mm seat height and 204 kg wet mass a bit tall and heavy, but the predictable engine and rider aids help shorten the learning curve.
The 2026 Aprilia Tuareg 660 specs read like a purpose-built blueprint: 80 hp, 70 Nm, fully adjustable KYB suspension with 240 mm travel at both ends, 240 mm ground clearance, cornering ABS with 3 maps, APRC, and spoked 21/18 wheels. It’s a package that puts capability first without sacrificing daily usability, backed by efficient fuel consumption and a clear 5‑inch TFT.
Weaknesses are few but worth noting: the 860 mm seat height and the 204 kg wet weight may challenge shorter or newer riders, and the 21‑inch front naturally prioritizes off-road stability over razor-edge road steering. For riders who value real dirt chops in a middleweight platform, the Tuareg 660 remains one of the most balanced choices.
