Most Common Problems with the Aprilia Pegaso 650:

Let’s break down the most frequently reported issues. These aren’t random complaints they are real mechanical or electrical concerns shared by Pegaso riders across the world.

1. Electrical System Issues

One of the most common complaints centers around electrical faults. Riders often report inconsistent starting behavior, intermittent power loss, and malfunctioning components like lights or the dashboard.

Causes Include:

This problem also occurs due to not having the motorcycle checked on a daily basis.
Worn-out battery.
Faulty stator or regulator/rectifier.
Corroded connectors, especially in wet climates.
Environmental elements can also cause this problem.

Maintenance Tips: Regularly inspect the wiring harness and connectors. Replacing the OEM regulator/rectifier with a higher-quality aftermarket unit can solve many issues.

2. Fuel System and Carburetor Problems

For earlier carbureted models, rough idling, poor throttle response, and fuel overflow are not uncommon. Fuel injection models have also shown surging at low RPMs.

Common symptoms:

This problem also occurs due to not having the motorcycle checked on a daily basis.
Difficulty starting in cold conditions.
Irregular engine RPM.
Poor fuel economy.
Environmental elements can also cause this problem.

Maintenance Tips: If you have a carbureted version, routine cleaning and correct jetting are essential. For fuel-injected versions, updating the ECU map or checking for vacuum leaks can help restore performance.

3. Oil Leaks and Engine Seals

Another known issue among Pegaso owners is oil leaking from the valve cover or cam chain tensioner. This doesn’t just make a mess—it can also lead to long-term engine wear if ignored.

Likely causes:

Old or brittle gaskets.
This problem also occurs due to not having the motorcycle checked on a daily basis.
Over-tightened bolts.
Excessive engine heat.
Environmental elements can also cause this problem.

Maintenance Tips: Use quality gaskets and torque the bolts to manufacturer specs. Keeping the engine cool and well-maintained helps prevent future leaks.

4. Starting Problems

Riders often express frustration with bikes that won’t start, even when the battery is charged. The problem sometimes lies with the side stand kill switch or the starter relay.

You might notice:

No crank despite turning the key.
Environmental elements can also cause this problem.
Engine cuts out unexpectedly.
This problem also occurs due to not having the motorcycle checked on a daily basis.
Bike only starts after wiggling wires.

Maintenance Tips: Bypass or clean the side stand switch and inspect the starter relay for corrosion. Always start diagnostics with a multimeter and work backward from the battery.

5. Overheating in City Traffic

While the Pegaso performs well on open roads, overheating during slow-speed city rides is a known issue, especially in warmer climates.

What to check:

This problem also occurs due to not having the motorcycle checked on a daily basis.
Radiator fan operation.
Coolant levels and circulation.
Thermostat functionality.
Environmental elements can also cause this problem.

Maintenance Tips: Install a manual fan switch for city riding. Flush the cooling system every season and replace the thermostat if necessary.

6. Brake problems

One of the most frequently mentioned issues is the rear brake feeling soft or not biting strongly enough. This problem is often caused by:

Old or contaminated brake fluid.
Air bubbles in the rear brake line.
Worn-out brake pads.
Poor-quality aftermarket parts.
Environmental elements can also cause this problem.

Maintenance Tips: Bleed the rear brake system, replace with high-quality DOT 4 brake fluid, and consider installing sintered brake pads for better bite.
