The Heart of Smooth Riding: Suzuki Access 125's Transmission

For those wondering about the type of transmission employed in the Suzuki Access 125, the answer is consistent across both its generations: it utilises a Continuously Variable Transmission (CVT). This choice of transmission is a significant factor in the Access 125's reputation for smooth and effortless acceleration, making it an ideal choice for urban environments and riders who prefer not to deal with manual gear shifting.

What is a Continuously Variable Transmission (CVT)?

Unlike traditional automatic transmissions that use a fixed number of gear ratios, or manual transmissions that require the rider to select gears, a CVT operates on a different principle. It uses two pulleys – a drive pulley and a driven pulley – connected by a drive belt. These pulleys can change their effective diameter, allowing for an infinite number of gear ratios within a specific range. As the engine RPM changes, the CVT system automatically adjusts these pulley diameters, ensuring the engine always operates at its most efficient speed for the given road conditions and throttle input.

Benefits of a CVT in Scooters

• Seamless Acceleration: With no distinct gear changes, acceleration is incredibly smooth and linear, free from the jerks often associated with traditional gear shifts.
• Optimal Engine Performance: The CVT keeps the engine in its optimal power band, leading to better fuel efficiency and reduced emissions.
• Simplicity for the Rider: Riders simply twist the throttle and go, without needing to worry about clutching or shifting gears, making it highly accessible for new riders and convenient for experienced ones.
• Reduced Mechanical Stress: By avoiding abrupt gear changes, the CVT can potentially reduce wear and tear on engine components over time.

Suzuki Access 125 Generations and Their Transmission

The Suzuki Access 125 has evolved through two main generations, both consistently relying on the robust and efficient CVT system:

1st Generation (2007-2016)

This initial model established the Access 125's strong presence in the market. It featured a carburettor fuel system and drum brakes, but its core transmission remained the CVT, providing the same smooth ride that users came to love.

2nd Generation (2016-Present)

The updated second generation brought several enhancements, including a shift to fuel injection for improved efficiency and performance, and the option of a front disc brake. Despite these upgrades, Suzuki wisely retained the CVT transmission, acknowledging its proven reliability and the seamless riding experience it offers.

Comprehensive Maintenance Schedule for Your Suzuki Access 125

Adhering to a strict maintenance schedule is paramount for the longevity and optimal performance of your Suzuki Access 125. Regular servicing not only prevents costly breakdowns but also ensures your scooter remains fuel-efficient and safe to ride. Below is a detailed maintenance schedule, outlining key components and their recommended service intervals.

Detailed Fluid Specifications

Using the correct fluids is crucial for your scooter's health. Here are the specifications for the Suzuki Access 125:

Key Maintenance Considerations

• Engine Oil: The engine oil lubricates moving parts, reduces friction, and helps cool the engine. Regular replacement ensures contaminants are removed and lubrication effectiveness is maintained. Using the specified grade and capacity is vital.
• Oil Filter: This component traps impurities from the engine oil. A clogged filter can restrict oil flow, leading to engine wear. Cleaning and timely replacement are essential.
• Air Filter: A clean air filter ensures optimal air-fuel mixture, crucial for engine performance and fuel efficiency. A dirty filter can choke the engine and increase fuel consumption.
• Spark Plug: Responsible for igniting the air-fuel mixture. A worn or fouled spark plug can lead to misfires, reduced power, and poor fuel economy.
• Valve Clearance: Proper valve clearance ensures efficient engine breathing. Incorrect clearance can lead to poor performance, excessive noise, or even engine damage. For the Access 125, the cold specifications are: Intake: 0.03-0.08mm, Exhaust: 0.08-0.13mm.
• Brake Fluid: Hydraulic brake systems rely on brake fluid to transmit force from the lever to the calipers. Brake fluid absorbs moisture over time, reducing its effectiveness and potentially leading to brake fade. Regular replacement is a safety critical item.
• Drive Belt: As the core component of the CVT, the drive belt is subject to wear and tear. Regular inspection for cracks, fraying, or stretching is important. Replacing it at the recommended interval (every 24,000 km) prevents sudden breakdowns and maintains smooth power delivery.

DIY Engine Oil Change for Your Suzuki Access 125

Changing your engine oil is one of the most fundamental maintenance tasks you can perform, and it's surprisingly straightforward for the Suzuki Access 125. Here's a step-by-step guide to doing it yourself, ensuring your scooter's engine stays healthy and well-lubricated.

Tools and Materials You'll Need:

• Ratchet wrench with a 14mm socket (for drain plug)
• 8mm spanner / 8mm box / 8mm ring spanner (for oil filter cap bolts)
• Flat screwdriver (useful for removing the old oil filter)
• Pliers (may be needed for a tight engine oil filler cap)
• A pan or container to collect old engine oil
• A funnel with a pipe attached (for pouring new oil)
• 1 litre of SAE 10W-30 API SL grade engine oil (e.g., Shell AX7)
• 1 new engine oil filter (e.g., Purolator make)
• 'O' ring set (optional, if existing ones are damaged)
• Clean cotton cloths
• Petrol (for cleaning parts)
• Empty engine oil pack for old oil disposal

Step-by-Step Procedure:

1. Preparation: Ensure the engine has not been started for at least an hour before you begin. This allows the oil to cool down and drain thoroughly. Place your scooter on its centre stand on a level surface.
2. Remove Filler Cap: Locate and remove the engine oil filler cap. This helps with proper oil drainage.
3. Drain Old Oil: Place your collection pan directly under the drain plug, located at the bottom of the engine. Use the ratchet wrench with the 14mm socket to carefully open the drain plug. Allow all the old, dark oil to completely drain out into the pan. This may take several minutes.
4. Access Oil Filter: While the oil is draining, locate the engine oil filter cap. It's usually secured by three bolts. Use your 8mm spanner to remove these bolts and carefully take off the cap.
5. Remove Old Oil Filter: Once the cap is off, gently pull out the old oil filter. You might need a flat screwdriver to carefully pry it out.
6. Inspect 'O' Rings: You'll find a larger 'O' ring attached to the filter cap and a smaller 'O' ring inside the cavity where the oil filter sits. Inspect both for any signs of damage, cracking, or flattening. If they appear worn or compromised, it's best to replace them.
7. Clean Components: Use a clean cotton cloth to thoroughly clean the oil filter cavity. Also, clean the filter cap, the spring, the three bolts, the drain plug, and the engine oil filler cap using a little petrol. If you're reusing the 'O' rings, clean them carefully with petrol too.
8. Replace Drain Plug: Once all the old oil has drained, replace the drain plug. Screw it in by hand as much as possible to avoid cross-threading, then tighten it securely with the ratchet wrench and 14mm socket. Do not overtighten.
9. Install New Oil Filter: Place the small 'O' ring in its correct position inside the oil filter cavity. Then, insert the new engine oil filter into the cavity. Remember, the oil filter has one open side and one closed side; ensure the closed side is facing outwards.
10. Reattach Filter Cap: Place the larger 'O' ring and the spring onto the oil filter cap. Carefully reattach the oil filter cap, securing it with the three bolts using your 8mm spanner. Tighten them evenly.
11. Add New Engine Oil: Place the funnel into the engine oil filler hole. Slowly pour in the new 0.8 litres of engine oil. Take your time to avoid spills.
