1985 Yamaha XV 750 Virago Technical Analysis & Specification Breakdown

Positioned in Yamaha's touring motorcycle lineup, the 1985 Yamaha XV 750 Virago pairs a 748 cc (45.6 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 51.8 HP (37.8 kW) at 7,500 rpm while maximum torque reaches 43.5 Nm (32.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 69.3 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the XV 750 Virago measures 238 kg (525 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.59 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,520 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank paired with a rated consumption of 8.2 L/100 km provides an estimated theoretical range of roughly 146 km (91 miles) between fill-ups, while factory top speed is listed at 174 km/h (108 mph).

Within MotoLibrary's Yamaha archive, this model family spans 6 indexed model years from 1985 to 1997, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.

Notes

Submitted to Bikez by visitor with the following comments: Frame # JYA56G007FA000878 Engine # 56G-000878 748cc. Yamaha does not recognize a 1985 XV750 Virago, since they switched to the 700 cc Virago in 1984. My bike was made in Oct/1984 and I cannot match the frame or engine number to Yamaha´s build list. I am trying to get an explanation from Yamaha but in the meantime, I have a Unique bike.
