The Yamaha XS 500 may not have anywhere near the street credentials of its big brother, the [[Yamaha XS650|XS 650]], but if you ride a parallel twin less than 30 years old you owe a debt of gratitude to the younger sibling. The technically-advanced engine made lots of power, though almost all of it came between 6,000rpm and the 9,000rpm redline. On early TX models this combined with poor fueling on throttle transitions, light flywheels, uneven power-pulses from the 180 degree crank and excessive driveline lash to make smooth part-throttle and stop start riding a real challenge. | |||

Due to its uninspiring appearance and unreliability it was held back from success. The first models had some problems with warping valve seats, so later cylinder heads were changed to round exhaust ports to help the heat dissipate. Heat remained a problem, frequently causing the head to fracture. The balancer and camchain arrangements needed regular attention. The XS offered good handling, but it was no lightweight so hardly came into the tarmac-tearing "road burner" category. When it went out of production in 1979 there were few who mourned its passing - and fewer still today who consider it to be wildly desirable. | |||

The Yamaha XS500 was a twin, four-stroke Naked motorcycle produced by Yamaha between 1975 and 1979. It could reach a top speed of 111 mph (178 km/h). Max torque was 32.45 ft/lbs (44.0 Nm) @ 6500 RPM. Claimed horsepower was 48.01 HP (35.8 KW) @ 8250 RPM.
Overview
The Yamaha XS 500 may not have anywhere near the street credentials of its big brother, the XS 650, but if you ride a parallel twin less than 30 years old you owe a debt of gratitude to the younger sibling. The technically-advanced engine made lots of power, though almost all of it came between 6,000rpm and the 9,000rpm redline. On early TX models this combined with poor fueling on throttle transitions, light flywheels, uneven power-pulses from the 180 degree crank and excessive driveline lash to make smooth part-throttle and stop start riding a real challenge.
The XS500, despite attracting all the right kind of attention at its launch back in 1972 failed to deliver. The combination of an air-cooled eight-valve head, 180-degree crank, double overhead cams, electric start and two CV carbs made for an extremely smooth and fairly porky middleweight twin.
Due to its uninspiring appearance and unreliability it was held back from success. The first models had some problems with warping valve seats, so later cylinder heads were changed to round exhaust ports to help the heat dissipate. Heat remained a problem, frequently causing the head to fracture. The balancer and camchain arrangements needed regular attention. The XS offered good handling, but it was no lightweight so hardly came into the tarmac-tearing "road burner" category. When it went out of production in 1979 there were few who mourned its passing - and fewer still today who consider it to be wildly desirable.
Engine
The engine was a air cooled twin, four-stroke. A 73.0mm bore x 59.6mm stroke result in a displacement of just 499.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive
The bike has a 5-speed transmission. Power was moderated via the wet, multi-disc.
Chassis
It came with a 3.25-19 front tire and a 4.00-18 rear tire. Stopping was achieved via single disc in the front and a single disc in the rear. The XS500 was fitted with a 3.96 Gallon (15.00 Liters) fuel tank. The wheelbase was 55.12 inches (1400 mm) long.
1975
1976
The XS500C was the revamped-for-1976 model and came with something resembling style and - even better -- something else, resembling durability.
