Buying a used Yamaha Exciter 570 with a 73mm piston (model number SPI YA570EX-PIK73) from the years 1987 to 1990 can be a viable option for off-road enthusiasts looking for a reliable and powerful ATV. Here are some pros and cons to consider before making a purchase.

1. Power: The 570cc, single-cylinder, four-stroke engine provides ample power and torque for various off-road conditions.

2. Durability: Yamaha's reputation for building high-quality ATVs ensures that these models are known for their robustness and longevity.

3. Versatility: The Exciter 570 comes with various features, such as electric starting, reverse gear, and a reliable CVT transmission, making it suitable for various riding styles and terrains.

4. Availability of parts: Due to their popularity, parts for these models are generally easy to find and relatively affordable.

1. Age and wear: These ATVs are quite old, and wear and tear on various components, such as engine, suspension, and electrical systems, may require maintenance or replacement.

2. Fuel efficiency: The larger engine size and older technology result in lower fuel efficiency compared to modern ATVs.

3. Lack of modern features: While the Exciter 570 offers a range of features for its time, it does not have the advanced technology and amenities that modern ATVs come with.

4. Safety concerns: Older ATVs may not have the same safety features as newer models, which could pose a risk for riders.

The Yamaha Exciter 570 with a 73mm piston is a capable and powerful off-road vehicle with a proven track record of durability and reliability.

Considering the pros and cons, if you are looking for a classic ATV for recreational use and are willing to invest in occasional maintenance, this could be a great option for you.
