The Suzuki Access 125 and Activa 125 are among the most popular scooters in India, known for their smooth performance, refined engines, and reliable ride quality. However, like any two-wheeler, they may experience engine heating issues during long rides—especially in hot weather, heavy traffic, or uphill routes. The good news is that these heating problems can be easily managed with the right maintenance habits and riding practices. Here’s how you can resolve and prevent engine heating issues in both scooters.
1. Use the Right Engine Oil
One of the biggest reasons for engine heating is degraded or poor-quality engine oil. Both Suzuki Access 125 and Activa 125 require high-grade oil to maintain smooth engine performance.
Tips:
Always use manufacturer-recommended oil.
Replace oil every 3,000–4,000 km.
Check for oil leaks regularly.
Fresh, good-quality oil improves cooling, reduces friction, and protects engine parts during long-distance rides.
2. Clean or Replace the Air Filter
Clogged air filters restrict airflow, forcing the engine to work harder. This leads to higher temperatures during longer rides.
To prevent this:
Check the air filter every 1,500–2,000 km.
Clean it if dusty; replace it if worn out.
Riders using the Access 125 or Activa 125 in dusty environments must clean the filter more frequently.
A clean air filter helps the engine breathe better and run cooler.
3. Avoid Riding at Constant High Speeds
Both scooters are designed for comfortable city commuting rather than continuous high-speed highway runs. Riding above 70 km/h for long periods increases engine load.
Ride efficiently by:
Maintaining a steady speed (50–60 km/h).
Taking short breaks every 20–25 km.
Avoiding aggressive acceleration.
These habits keep the engine temperature stable, especially during summer.
4. Check the Cooling System
Scooters like the Suzuki Access 125 and Activa 125 rely on air-cooling. If airflow is blocked, the engine heats up quickly.
What you should do:
Ensure the cooling fins are clean.
Avoid placing bags or accessories that block airflow around the engine area.
Get the cylinder fins inspected during servicing.
Proper airflow helps dissipate heat efficiently.
5. Maintain Correct Engine Tuning
Incorrect carburetor or fuel-injection tuning can cause overheating. Poor tuning affects combustion efficiency.
Solution:
Get tuning checked every 4,000–5,000 km.
Ensure the scooter idles smoothly.
Avoid modifications that alter the air–fuel mixture.
Proper tuning improves mileage and keeps engine temperature low.
6. Avoid Overloading the Scooter
Carrying excessive weight puts extra pressure on the engine.
To prevent this:
Stick to the recommended load capacity.
Avoid carrying heavy luggage on the footboard or hooks.
Overloading not only increases heat but also reduces engine life.
7. Service Your Scooter on Time
For both Suzuki Access 125 and Activa 125, timely servicing is the simplest way to avoid heating issues.
A periodic check-up includes:
Engine oil change
Air filter cleaning
Spark plug inspection
Brake and clutch adjustment
Cooling fin cleaning
Regular service keeps your scooter reliable and heat-free during long rides.
Conclusion
Engine heating in the Suzuki Access 125 and Activa 125 is common during long-distance rides, but with proper maintenance and smart riding habits, it can be easily controlled. Using the right engine oil, keeping filters clean, maintaining steady speeds, and ensuring timely servicing can significantly reduce overheating. By following these tips, your scooter will stay smooth, cool, and ready for every journey—short or long.
