The Suzuki Savage 650, also known affectionately as the LS650, is a classic motorcycle that has garnered a loyal following thanks to its simple, robust design and torquey single-cylinder engine. A common question that arises for both prospective and current owners is about its gearbox. Understanding the number of gears, their configuration, and how to properly maintain this vital component is crucial for ensuring the longevity and performance of your Savage. This article will provide a comprehensive overview of the Suzuki Savage 650's gearbox, addressing common queries and offering practical advice.
The Suzuki Savage 650 Gearbox: A Closer Look
The Suzuki Savage 650 is equipped with a five-speed constant mesh transmission. This means that all of the gears within the gearbox are always in mesh with each other. Shifting gears involves engaging different gear combinations using the shift drum, which is actuated by the rider via the gear lever. This type of transmission is known for its durability and relatively straightforward operation, contributing to the Savage's reputation as a reliable machine.
Understanding Gear Ratios
The specific gear ratios in a motorcycle's transmission significantly impact its performance characteristics, affecting acceleration, top speed, and fuel economy. While exact figures can vary slightly depending on the specific model year or regional variations, the general configuration of the Savage 650's gearbox is designed to provide a good balance between city riding usability and highway cruising capability. The lower gears are typically shorter, offering strong acceleration from a standstill, while the higher gears are longer, allowing the engine to operate at lower RPMs at cruising speeds, thus improving comfort and fuel efficiency.
Here's a typical breakdown of the Suzuki Savage 650's gear ratios (note: these are approximate and can be confirmed with your specific model's service manual):
| Gear | Ratio (Approximate) |
|---|---|
| 1st | 2.538 |
| 2nd | 1.750 |
| 3rd | 1.318 |
| 4th | 1.077 |
| 5th | 0.917 |
These ratios indicate that the first gear provides the most torque multiplication for acceleration, and as you move up the gears, the ratios become numerically smaller, leading to higher road speeds for a given engine RPM. The 5th gear, being an overdrive gear (ratio less than 1.0), allows the engine to "wind down" on the highway.
Common Gearbox Maintenance for Your Savage 650
Proper maintenance of the gearbox is paramount for its smooth operation and longevity. The primary maintenance task involves ensuring the correct level and condition of the gearbox oil. The Savage 650's gearbox shares its oil with the engine's crankcase, meaning regular oil and filter changes are essential for both components.
Gearbox Oil: What You Need to Know
- Type of Oil: Always use an oil specifically designed for motorcycles with a wet clutch system. These oils contain friction modifiers that are essential for proper clutch operation. Using automotive oil can lead to clutch slippage. Look for oils that meet JASO MA or JASO MA2 standards.
- Viscosity: The recommended viscosity is typically 10W-40, but it's always best to consult your owner's manual for the precise recommendation for your climate and specific model year.
- Oil Change Interval: Suzuki typically recommends an oil change every 3,000-4,000 miles (5,000-6,000 km) or annually, whichever comes first. However, if you ride in dusty conditions or frequently short trips, more frequent changes might be beneficial.
- Checking the Oil Level: The oil level should be checked regularly. Most motorcycles have a sight glass or a dipstick. For the Savage 650, it's typically checked with the bike upright on a level surface. Refer to your manual for the exact procedure.
Clutch Adjustment
While not directly part of the gearbox itself, the clutch is intrinsically linked to its operation. A properly adjusted clutch ensures smooth engagement and disengagement, preventing premature wear on gearbox components and providing a positive shifting experience. Over time, the clutch cable can stretch, requiring adjustment. Check your owner's manual for the correct procedure for adjusting the clutch free play.
Troubleshooting Common Gearbox Issues
Even with diligent maintenance, some issues can arise with a motorcycle's gearbox. Here are a few common problems and their potential causes:
- Difficulty Shifting Gears: This can be caused by low or degraded gearbox oil, a misadjusted clutch, worn shift forks, or damaged gear dogs.
- Gears Slipping Out of Mesh: This is often a sign of worn engagement dogs on the gears or a problem with the shift drum or detent mechanism.
- Grinding Noises When Shifting: This usually indicates that the clutch is not fully disengaging, or there might be issues with the synchronisation (though the Savage 650's gearbox doesn't have synchronisers in the automotive sense, the concept of smooth engagement applies). Ensure the clutch is properly adjusted and the oil is clean.
- False Neutrals: A false neutral occurs when the gear lever indicates engagement, but the transmission is not fully in gear. This can be due to worn shift components or incorrect gear engagement.
If you experience any of these issues, it's best to have your motorcycle inspected by a qualified mechanic. Attempting complex gearbox repairs without the necessary knowledge and tools can lead to further damage.

Frequently Asked Questions
How many gears does the Suzuki Savage 650 have?
The Suzuki Savage 650 has a five-speed gearbox.
Can I use car oil in my Savage 650 gearbox?
No, you should never use car oil in a motorcycle with a wet clutch system like the Savage 650. Use only motorcycle-specific oil that meets JASO MA or JASO MA2 standards.
What is the recommended oil change interval for the Savage 650?
Typically, it's recommended to change the oil and filter every 3,000-4,000 miles (5,000-6,000 km) or annually, whichever comes first. Always check your owner's manual for the most accurate information.
Why is my Savage 650 hard to shift?
Difficulty shifting can be due to low or old oil, a clutch that needs adjustment, or internal gearbox wear. It's advisable to get it checked by a professional.
What is a false neutral on a motorcycle?
A false neutral is when the gear indicator suggests you are in gear, but the motorcycle is not actually engaged in a gear, often occurring between actual gears.
Remember, proper maintenance and understanding of your Suzuki Savage 650's gearbox will ensure a safer and more enjoyable riding experience. Always refer to your owner's manual for specific details pertaining to your model.
