Battery Draining Too Fast
Battery Ducati Monster 659 Problems are a major, genuine problem that can cause a lot of damage to a motorcycle and can even lead to a major accident. This can affect the entire electrical system. If the battery is damaged, the electrical system will not work, which will make the motorcycle completely useless and also endanger the life of the rider, especially if the indicators do not work.
The main causes of the problem are as follows:
Many owners report that their Ducati Monster 659 has Problems: battery drains quickly, even when the motorcycle is not in use for long periods. Some individuals may experience starting problems after a week of inactivity. Failure to check the battery daily, failure to properly fill the float in it, and loose or overtightened battery bolts are also major causes of this problem. A substandard battery does not last long, which is why it deteriorates quickly. That also causes this problem, or if an accident happens, the battery also deteriorates.
The best solution to the problem is as follows:
- Always use a battery tender/charger if you don’t ride daily.
- Tightening the battery’s nuts and bolts properly, protecting them from drying out, and properly waxing them will also help prevent damage.

The main causes of the problem are as follows:
The mirrors on the Ducati Monster 659 are known to wobble or gradually droop due to poor factory tension or vibration from the L-twin engine. This problem occurs due to not tightening nuts and bolts properly or due to an accident.
The best solution to the problem is as follows:
- Use thread locker (Loctite Blue) on the mirror bolts.
- Tighten nuts and bolts properly so that they do not move.
- Purchase and use its parts only according to standards and company instructions.
- Upgrade to bar-end mirrors or aftermarket vibration-resistant options.
- Add anti-vibration washers or rubber grommets.
- Improving the quality of driving as much as possible and keeping the speed low if the road is bad will also eliminate this problem.
A simple fix, but essential for safe visibility at highway speeds.
Gear Shifting Trouble in Lower Gears
Gear shifting is also a major problem that causes a lot of trouble for the rider and can even lead to a major accident. This has been noted by many riders regarding this.
The main causes of the problem are as follows:
Some owners report difficulty engaging first or second gear smoothly, often noticing a hard “clunk” or stiffness in the shift lever. This problem can also occur due to improper lubrication of parts, improper driving, use of improper parts, or an accident.
The best solution to the problem is as follows:
- Perform a clutch cable adjustment or lubrication.
- Properly lubricating the gear and all the parts connected to it and properly tightening the nuts will also eliminate this problem.
- Use high-performance gear oil to ease shifting.
- If persistent, consider replacing the shift lever spring or gear selector mechanism.
- Properly managing hardness and stiffeness will also eliminate this problem.
This problem is more noticeable in cold starts or poorly maintained units.
Expensive Maintenance & Valve Service Costs: Ducati Monster 659 Problems
This is also a common problem that causes a lot of problems for both the rider and the motorcycle.
The main causes of the problem are as follows:
As with most Ducati motorcycles, the 659 also requires desmodromic valve adjustments and timing belt replacements at regular intervals, leading to high service costs. This problem also arises because of the system I have not optimized and not having it checked properly.
The best solution to the problem is as follows:
- Schedule combined services to reduce labor costs.
- It is better to get it serviced by the shop appointed by the company.
- Use independent Ducati-certified mechanics instead of dealerships.
- Its daily checkup does not cause any major problems, as it ends up being a little bit early and the expenses are not too much.
- Learn basic DIY tasks like oil, brake fluid, and belt checks.
- This problem can be largely solved with proper maintenance and improved driving quality.
Average service cost per year: $350–$700, depending on region and mechanic.
Seat Height and Wide Handlebar Challenges
The seat height issue is a major issue and riders have complained a lot about it, especially old-age riders who have taken note of their complaints.
The main causes of the problem are as follows:
With a seat height of approx. 785mm (30.9″), shorter riders may find the wide handlebars and upright stance uncomfortable, especially during city rides or lane filtering. Irregular driving, irregular roads, not sitting properly, irregular driving and many other such symptoms are also the main causes of this problem.
The best solution to the problem is as follows:
- Install a lowering kit or low-profile seat foam.
- Having a professional mechanic adjust the motorcycle seat to your height will also eliminate this problem.
- By improving the rider’s sitting position and properly wearing driving suite.
- Swap to narrower handlebars with risers to improve wrist comfort.
