How many cylinders does the Yamaha R6 have?

[VonBeckett]

Yamaha R6 is equipped with an inline 4-cylinder engine. Below is relevant information about the Yamaha R6: 1. Body dimensions: The Yamaha R6 measures 20407051095mm in length, width, and height, with a seat height of 850mm, a minimum ground clearance of 130mm, a wheelbase of 1375mm, a curb weight of 189kg, and a fuel tank capacity of 17 liters. 2. Powertrain: The Yamaha R6 engine has an actual displacement of 599cc, four cylinders, a four-stroke cycle, four valve chambers, utilizes a DOHC valve train structure, with an engine compression ratio of 13.1, producing a maximum power of 91kw and a maximum torque of 65.7N-m.

Speaking of the Yamaha R6's engine configuration, I have to tell you it features a classic inline-four design. This middleweight sportbike's four-cylinder engine has a displacement of 599cc, with a redline that soars to 16,000 RPM, delivering exceptional explosive power. During my test ride, I deeply experienced how the four-cylinder's smoothness and high-revving exhaust note make it a track weapon, though fuel consumption is higher for daily commuting. Every maintenance session requires special attention to cylinder cooling, given the four-cylinder's high operating temperatures. Compared to twin-cylinder KTMs, the R6 shows obvious advantages in high-speed stability, but the increased weight demands more refined cornering techniques.

I've disassembled and repaired numerous Yamaha R6 motorcycles, confirming they are equipped with an inline-four engine. This four-cylinder layout is exceptionally compact, with a cylinder bore of 67mm and stroke of 42.5mm - a typical short-stroke high-revving configuration. During maintenance, special attention must be paid to timing chain alignment, and replacing all four spark plugs is more complicated than on single-cylinder bikes. Once encountered a owner complaining about cold start issues, which turned out to be a clogged fuel injector in the third cylinder. I recommend regular bore-scope inspections for carbon buildup, as four-cylinder imbalance can significantly affect power delivery. These precision machines require full synthetic oil, and their clutch plates wear out about 30% faster than twin-cylinder models.

Having ridden motorcycles for over a decade, the Yamaha R6's inline-four engine is renowned in the circle as a fierce performer. The four-cylinder configuration allows it to unleash nearly 120 horsepower at 14,000 RPM, though it feels a bit sluggish at low revs and isn't as nimble as a twin-cylinder bike in stop-and-go city traffic. What I love most is its whistling sound, especially the four-cylinder resonance when downshifting and blipping the throttle in tunnels—it's like a soundtrack from a racing movie. However, it takes longer to warm up in winter since four-cylinders heat up slowly. Tire wear is also rapid; if you're continuously carving mountain roads, the rear tire needs replacing every 2,000 kilometers—blame the brutal power. In the same class, there's the Honda CBR600, but Yamaha's crossplane crankshaft design offers better vibration resistance.

My friend just bought a used Yamaha R6, and I confirmed it has a four-cylinder engine during the inspection. Based on the frame number, models after 2006 are liquid-cooled four-cylinder, while older versions are carbureted. Pay special attention to checking the cylinder pressure balance of the four cylinders. If the pressure difference exceeds 10% when we connect the diagnostic tool, an overhaul is needed. For modifications, switching to a 4-into-2 exhaust can reduce weight by 7kg but will weaken low-end torque. The cooling system of this bike requires special maintenance, as there have been cases where a four-cylinder engine seized due to a clogged radiator. After track days, it's essential to check the color of all four spark plugs to ensure even combustion.
