The Cota 248 features a robust and lightweight frame, designed to ensure agility and stability on various off-road surfaces. The suspension system, consisting of a leading-link fork in the front and a swingarm with a hydraulic shock absorber in the rear, provides exceptional handling and comfort, even during high-speed maneuvers or when tackling rough terrain.

The Montesa 5166.118 Cota 248 is outfitted with 21-inch front and 19-inch rear wheels, fitted with knobby tires for superior grip and traction. The front and rear brakes are hydraulic disc brakes, ensuring reliable stopping power in all conditions.

The Cota 248's post P/N is 21M 51M, making it easy to identify and order genuine Montesa replacement parts if needed. This model's timeless design and exceptional performance make it a sought-after collector's item among off-road motorcycle enthusiasts.

The Montesa 5166.118 Cota 248 (1979-1984) is a vintage enduro motorcycle, known for its robustness, agility, and off-road capabilities. Here are some pros and cons to consider before making a purchase:

1. Historical Significance: This model is a classic in the world of off-road motorcycles. Owning a vintage Montesa gives you the opportunity to own a piece of motocross history.

2. Unique Appeal: Vintage motorcycles like the Cota 248 have a distinct charm that modern bikes can't replicate. They often attract attention and admiration from fellow enthusiasts.

3. Handling: Known for its agility and lightweight design, the Cota 248 is a joy to ride off-road, providing a thrilling and authentic experience.

4. Restoration Potential: If you're into restoration projects, this bike offers a great opportunity to learn, restore, and customize a classic motorcycle.

1. Maintenance and Parts: As a vintage model, finding parts and performing maintenance can be challenging and expensive. Some parts may require special ordering or custom fabrication.

2. Reliability: Compared to modern motorcycles, the Cota 248 may not be as reliable, especially if it hasn't been well-maintained. Regular maintenance is crucial to ensure its longevity.

3. Comfort: Vintage motorcycles, especially enduro models, are often less comfortable than modern bikes. Long rides may not be as enjoyable due to hard seats, lack of suspension comfort, and other factors.

4. Lack of Modern Features: The Cota 248 lacks many modern features such as ABS, electronic fuel injection, and other safety and convenience features found in modern motorcycles.

The Montesa Cota 248 is a unique and charming motorcycle with a rich history in the world of off-road racing. If you're a vintage motorcycle enthusiast, enjoy restoration projects, and don't mind the challenges associated with maintaining a vintage bike, the Cota 248 could be an excellent choice. However, if you're looking for a reliable daily rider or a bike that's easy to maintain, you may want to consider a modern enduro motorcycle instead.

If you're set on owning a Montesa Cota 248, I recommend researching extensively, finding a well-maintained example, and being prepared for the potential challenges and costs associated with owning a vintage motorcycle. It's also a good idea to join online communities or local clubs of vintage motorcycle enthusiasts for advice and support. If you're new to vintage motorcycles, it might be wise to start with a less expensive and more easily maintained model to gain experience before investing in a Cota 248.
