Tire Specifications
The 120/70 x 17 tire is a common size for dual-sport motorcycles. The first number, 120, represents the width of the tire in millimeters. The second number, 70, represents the aspect ratio, which is the ratio of the tire’s height to its width.
In this case, the aspect ratio is 70%, meaning that the tire’s height is 70% of its width. The third number, 17, represents the diameter of the rim in inches.
Intended Use
The 120/70 x 17 tire is designed for dual-sport motorcycles, which are motorcycles that are designed to be ridden on both on-road and off-road surfaces. The tire’s wide profile and deep tread pattern provide good traction on both paved and unpaved roads.
The tire’s aspect ratio of 70% provides a good balance of on-road and off-road performance. The tire’s rim diameter of 17 inches is a common size for dual-sport motorcycles.
Tread Pattern and Design
The 120/70 x 17 dual-sport tire features an aggressive tread pattern designed to excel in both on-road and off-road conditions. The combination of large, widely spaced blocks and deep siping provides exceptional traction on a variety of surfaces.
On-Road Performance
On paved roads, the large tread blocks provide stability and minimize road noise, ensuring a comfortable and controlled ride. The siping, or small cuts in the tread blocks, enhances traction on wet or slippery surfaces, improving handling and braking performance.
Off-Road Performance
When venturing off-road, the widely spaced blocks dig into loose terrain, providing excellent grip and preventing the tire from sinking. The deep siping allows the tire to flex and conform to uneven surfaces, maintaining traction and stability in challenging conditions.
Impact on Traction, Handling, and Stability
The aggressive tread pattern significantly improves traction on both on-road and off-road surfaces. The large tread blocks provide ample surface area for grip, while the siping enhances traction in wet or loose conditions. This combination results in improved handling and stability, allowing riders to confidently navigate a wide range of riding environments.
Compound and Construction
The compound and construction of a tire significantly influence its performance, durability, and puncture resistance. The compound refers to the rubber mixture used in the tire’s tread, while the construction involves the arrangement and materials of the tire’s internal structure.
The tire’s compound is optimized to provide a balance between grip, wear resistance, and rolling efficiency. A softer compound offers better grip but wears out more quickly, while a harder compound lasts longer but provides less traction. The 120/70 x 17 dual sport tire typically features a dual-compound construction, with a harder center section for longevity and softer shoulder sections for improved cornering grip.
Construction
The tire’s construction determines its overall strength and puncture resistance. The 120/70 x 17 dual sport tire often employs a radial construction, where the tire’s cords run perpendicular to the direction of travel. This design enhances stability and provides a more comfortable ride.

The materials used in the tire’s construction play a crucial role in its performance. High-quality rubber compounds ensure durability and grip, while advanced fiber materials like aramid and nylon enhance puncture resistance and overall strength.
Load and Speed Rating
The load index and speed rating of a tire indicate its maximum load capacity and safe operating speed. Choosing the correct load and speed rating is essential for ensuring safety and performance.
Load Index
The load index is a number that represents the maximum load the tire can carry at its maximum inflation pressure. It is important to choose a tire with a load index that is equal to or greater than the weight of your motorcycle and rider, plus any luggage or accessories.
Speed Rating, 120/70 x 17 dual sport tire
The speed rating is a letter that indicates the maximum safe operating speed for the tire. It is important to choose a tire with a speed rating that is equal to or greater than the maximum speed you expect to ride.
The load index and speed rating are typically found on the sidewall of the tire. For example, a tire with a load index of 70 and a speed rating of T is rated for a maximum load of 335 kg (739 lbs) and a maximum safe operating speed of 190 km/h (118 mph).
