If you own a 2018 KTM Duke 390, understanding the tire size is crucial for both performance and safety. The tire size can significantly affect handling, stability, and overall riding experience. Let’s break down the stock tire sizes for different trims of the Duke 390 and how they can impact your ride.
Stock Tire Sizes
The 2018 KTM Duke 390 comes with specific tire sizes that cater to its performance-oriented design. Here’s what you need to know:
| Trim | Front Tire Size | Rear Tire Size |
|---|---|---|
| Duke 390 | 110/70-17 | 150/60-17 |
Front Tire Details
The front tire size of 110/70-17 is designed to provide excellent grip and responsiveness. Here’s a breakdown of what this size means:
- 110: This is the width of the tire in millimeters. A wider tire can offer more grip, which is essential for cornering.
- 70: This is the aspect ratio, indicating the height of the tire’s sidewall as a percentage of the width. A lower ratio means a shorter sidewall, which enhances stability.
- 17: This is the diameter of the wheel in inches. The 17-inch size is common for sport bikes, allowing for better handling at higher speeds.
Rear Tire Details
The rear tire size of 150/60-17 is equally important for the Duke 390’s performance. Here’s what this size represents:
- 150: This is the width of the rear tire in millimeters. A wider rear tire provides better traction, especially when accelerating.
- 60: This aspect ratio indicates a slightly taller sidewall compared to the front tire, which helps absorb bumps and provides a comfortable ride.
- 17: Again, this is the diameter of the wheel in inches. The consistency in wheel size between front and rear helps maintain balance and handling characteristics.
Impact on Performance
Choosing the right tire size is not just about fitting the bike. It directly impacts various aspects of performance:
- Handling: The stock tire sizes are engineered to provide optimal handling characteristics. Deviating from these sizes can lead to unpredictable behavior, especially in corners.
- Stability: The balance between the front and rear tire sizes is vital for stability. A mismatch can cause the bike to feel unstable, particularly at high speeds.
- Traction: The grip provided by the tires is essential for safe acceleration and braking. Stock sizes are tested to ensure maximum grip under various conditions.
Aftermarket Options
If you’re considering aftermarket tires, keep these points in mind:
- Stick to the recommended sizes to maintain handling and stability.
- Consider the type of riding you do. For example, sportier tires may offer better grip but can wear out faster.
- Consult with a professional mechanic or tire specialist to choose the best options for your riding style.
Understanding the tire size of your 2018 KTM Duke 390 is essential for maintaining performance and safety on the road. Always ensure that your tires are in good condition and properly inflated for the best riding experience.

- Improved handling in tight corners, making the bike feel more nimble.
- Some riders experienced reduced stability at higher speeds, particularly during aggressive riding.
- Less grip in wet conditions, which can be a safety concern.
While smaller tires can enhance agility, they may not be the best choice for everyone. Always consider your riding style and the conditions you typically ride in.
Biggest Tire Size Options
On the flip side, some riders opt for larger tires to enhance grip and stability. Here are some sizes that have been discussed in forums:
- Front Tire: A 120/70-17 tire is a popular choice among those looking for a bit more grip and stability. It can provide a more planted feel during cornering.
- Rear Tire: The 160/60-17 tire is often recommended for those wanting to maximize traction and performance. This size can improve acceleration and braking performance.
Owner Feedback on Larger Tires
Riders who have switched to larger tires commonly report:
- Significantly enhanced grip, especially in aggressive cornering situations.
- Improved stability at high speeds, making long rides more comfortable.
- Some noted a slight decrease in agility, particularly in tight urban scenarios.
While larger tires can offer performance benefits, they may alter the bike’s handling characteristics, so it’s essential to weigh the pros and cons.

When deciding on tire size, consider the following factors:
- Riding Style: Are you a commuter, a weekend warrior, or a track day enthusiast? Your riding style will significantly impact your tire choice.
