**1987 Yamaha TZR250: A Legendary Sport Bike**

The 1987 Yamaha TZR250 was a groundbreaking motorcycle that revolutionized the sport bike segment. It introduced a host of innovative features that set the standard for performance and handling for years to come.

**Engine:**

At the heart of the TZR250 was its liquid-cooled, two-stroke, parallel-twin engine with Yamaha's revolutionary Genesis Chamber Induction System. This innovative system employed a special exhaust port design to create a scavenging effect that improved combustion efficiency, resulting in impressive power output and fuel economy. With a maximum power of 45 horsepower at 10,500 rpm and a peak torque of 25 lb-ft at 8,500 rpm, the TZR250 had one of the most potent engines in its class.

**Chassis:**

The TZR250's chassis was equally impressive, featuring a lightweight Deltabox aluminum frame that provided exceptional rigidity and handling precision. Its adjustable 37mm front forks and preload-adjustable monoshock rear suspension offered a comfortable and responsive ride. The bike's aggressive geometry, with a steep steering rake and short wheelbase, contributed to its agile and responsive handling, making it a formidable opponent on both the track and the street.

**Brakes:**

The TZR250 boasted a top-notch braking system, with dual 267mm floating front discs and a single 220mm rear disc. These high-performance brakes provided excellent stopping power and feel, ensuring confident control under any riding condition.

**Bodywork:**

The TZR250's striking bodywork was not only visually appealing but also aerodynamically efficient. Its sleek, sculpted fairing reduced wind resistance, while its aerodynamic tail section added stability at high speeds. The bike's distinctive inverted front forks and compact engine gave it a distinctively aggressive and futuristic appearance.

**Electronics:**

The TZR250 was equipped with advanced electronics for its time, including a digital tachometer and speed indicator. Its CDI ignition system ensured reliable spark delivery, while its automatic oil injection system eliminated the need for manual mixing.

**Conclusion:**

The 1987 Yamaha TZR250 was a true masterpiece of engineering and design. It combined a powerful engine, nimble chassis, exceptional brakes, and striking bodywork to create a motorcycle that dominated the sport bike market. Its influence is still felt today, as many modern sport bikes continue to incorporate design elements and technologies pioneered by the TZR250.
