7 Problems with Aprilia Dorsoduro 750 I Never Know Before

The Aprilia Dorsoduro 750, an exciting fusion of supermoto and streetfighter, is known for its high-performance features and distinctive style. 

However, like any machine, it comes with its own set of challenges. 

So, in this article, we will cover the common problems of Aprilia Dorsoduro 750 and provide you with solutions.

Let’s begin!

Aprilia Dorsoduro 750 Problems

Aprilia Dorsoduro 750 problems are connection wire, ECU, head bearings, fork seal leakage issues, chain & rear tire replacement, tank, and overheating problems.

1. Connection Wire and ECU Problems

One of the common issues with the Aprilia Dorsoduro 750 is related to its connection wires and the Engine Control Unit (ECU). 

Over time, the connection wires, particularly the ones linked to the starter, may loosen. 

This can cause the ignition to become unreliable, and in some cases, the motorcycle may fail to start altogether. 

A simple solution is to regularly inspect the starter connections and tighten them if they appear loose.

Moreover, the pins of the ECU connectors can become rusty due to exposure to rainwater. 

This rust can lead to a loss of connectivity between the ECU and the engine, affecting the performance of the bike. 

So, you can resolve this by periodically checking the ECU connector pins and cleaning any rust that has formed. 

You can do this by using a small wire brush or a rust remover spray. Applying a silicone or petroleum-based sealant around the connectors will prevent future rust formation.

Poor headlight visibility is another issue that can arise due to these wiring and ECU problems. 

If the headlights aren’t as bright as they should be, inspect the headlight wiring and connections for any signs of damage or disconnection. 

You should replace any damaged wires or connectors, ensuring that they are properly sealed against moisture to prevent future problems.

2. Head Bearings and Fork Seals Leakage

This issue can lead your motorcycle to a significant shake in the front fork, a condition that can wear down the fork seals over time, causing them to leak.

To resolve this issue, you should first inspect the bearings. If they are worn out or damaged, you’ve to replace them. 

You can purchase a new set of bearings from a motorcycle parts supplier. During installation, ensure that the bearings are properly seated and greased.

While fork seal leakage is typically a result of the shaking bearing. Once the bearing issue is resolved, the seal leakage should subside. 

But if the seals have been compromised, you’ll need to replace them. Fork seals are available at most motorcycle parts stores. 

3. Chain and Rear Tires Replacement

The chain and sprocket set on your Aprilia Dorsoduro 750 may fail due to misalignment, rust, and wear and tear. 

To prevent this, you should ensure regular inspection and cleaning of your chain, and lubricate it with a quality chain lubricant. 

Also, prevents rust and reduces friction that can cause wear. If misalignment is the issue, a chain alignment tool can assist you in making necessary adjustments.

The stock rear tires of Aprilia Dorsoduro 750 are also known to wear out sooner than expected.

To prevent frequent tire changes, you should invest in high-quality, durable tires that are suitable for your riding conditions.

4. Bulky Motorcycle and Unoptimized Exhaust

One of the other concerns raised by owners of the Dorsoduro 750 is the motorcycle’s considerable weight, tipped over 400 pounds, paired with a bulky exhaust system. 

This combination can prove challenging, particularly for beginner riders or those of a smaller stature.

One possible solution is to consider replacing the factory exhaust system with an aftermarket unit that is lighter and more compact. 

This can reduce the overall weight of the bike and help improve its center of gravity, making it more manageable and easier to handle. 

Plus, many riders have found that an aftermarket exhaust can enhance the bike’s performance and sound. 

5. Tank Problems 

Aprilia Dorsoduro 750 owners also have reported fuel tank issues, believed to be caused by the use of ethanol-blended fuel.

Ethanol, found in most gasoline, can cause the plastic fuel tank on the Dorsoduro 750 to warp, and leading to potential fuel leaks. 

This not only poses a safety risk but it can also limit the bike’s range due to the tank’s smaller capacity.

One solution to this issue is to replace the plastic fuel tank with a metal one. 

Metal fuel tanks are more resistant to the warping effects of ethanol and eliminate the risk of leakage due to warping. 

Alternatively, you can use ethanol-free fuel, if available, it can also prevent the warping of the plastic tank.

Another solution is the use of fuel additives that protect against the damaging effects of ethanol. 

6. Overheating issues

This problem can have serious implications if not addressed promptly, leading to significant engine damage. 

One solution is to replace the radiator fan. You can find a replacement part from a trusted auto parts dealer. 

Then carefully remove the malfunctioning fan, following the manufacturer’s instructions, and install the new one. 

Alternatively, if the fan is functioning but the bike is still overheating, the issue might lie with the coolant. 

In such cases, it is advisable to flush the cooling system and refill it with a high-quality coolant. 

Finally, ensure the radiator is not blocked or damaged, as this could also contribute to overheating issues. 

7. Electrical Gremlins

These can manifest in various ways, such as erratic instrument panel readings or an unresponsive ignition.

The first port of call in troubleshooting electrical issues is to inspect the battery. Ensure it’s fully charged and terminals are clean, devoid of any corrosion. 

You should also, check the battery cables for any wear or damage. Damaged cables can lead to voltage drops affecting the functioning of the electrical system.

Next, you should inspect the wiring and connectors throughout the bike. Loose or frayed wires can cause intermittent electrical issues. 

You can use a multimeter to check for any abnormalities in the wiring system. Ensure safety precautions when dealing with electricity.

Lastly, a faulty regulator/rectifier can often be the culprit of electrical issues. Check its health using a multimeter. 

If it’s not providing the right amount of voltage to the battery, it might need to be replaced. 

This is an advanced step, if you are not familiar with it you can get in touch with a professional.
