Review SUZUKI 137 Ignition Switch fits LT80 1991

The **Suzuki 37110-40B00 (and compatible 37110-40B01, 137, 1991 LT80)** ignition switch is a precision-engineered component designed specifically for Suzuki s classic LT80 (also known as the Suzuki LT80 or "Suzuki 80") off-road motorcycle, produced in the early 1990s. This ignition switch serves as the critical interface between the rider and the motorcycle s electrical system, controlling the flow of power to the ignition coil, starter motor, and other essential circuits while ensuring reliable operation in rugged, off-road conditions. Crafted from durable materials, the switch features a robust metal housing with a weather-resistant design to withstand exposure to dust, moisture, and the harsh elements encountered during off-roading adventures. The internal mechanism incorporates a high-quality, long-lasting contact system that minimizes wear and prevents corrosion, reducing the risk of intermittent electrical failures that could leave you stranded in remote terrain. The switch is equipped with a secure, ergonomic lever or knob, depending on the model variant, allowing for smooth, one-handed operation even while wearing gloves a practical consideration for riders prioritizing efficiency and safety. Compatible with the LT80 s 1991 model year and later iterations, this ignition switch is a direct-fit replacement for the original unit, ensuring seamless integration with the motorcycle s wiring harness and ignition system. Whether you re restoring a vintage LT80 or maintaining a well-loved off-road machine, this switch guarantees reliable performance, helping to preserve the integrity of your motorcycle s electrical components and ensuring that every ride begins with a turn of the key no matter how remote or challenging the destination.

### Pros and Cons of buying a Suzuki Ignition Switch (Part Numbers: 37110-40B00, 37110-40B01, 137, 1991 LT80)

1. **Compatibility** These ignition switches are designed specifically for the 1991 Suzuki LT80 (and similar models), ensuring a perfect fit without modification. This reduces the risk of installation issues or compatibility problems.

2. **Reliability** Suzuki parts are generally built to last, and these switches are no exception. They are designed to withstand regular use, reducing the likelihood of frequent failures.

3. **Ease of Installation** Since these are OEM (Original Equipment Manufacturer) or high-quality aftermarket parts, they often come with clear instructions and may require minimal tools for replacement. This makes DIY installation feasible for those with basic mechanical skills.

4. **Cost-Effective** Compared to full engine replacements or professional labor costs, replacing just the ignition switch is a relatively inexpensive fix. Prices for these parts are reasonable, especially when sourced from reputable suppliers.

5. **Prevents Further Damage** A faulty ignition switch can lead to electrical issues, starter problems, or even engine damage if left unaddressed. Replacing it early can prevent more costly repairs down the line.

6. **Improved Safety** A malfunctioning ignition switch can pose safety risks, such as the engine cutting off unexpectedly while driving. A new switch ensures consistent operation and reduces accident risks.

7. **Availability of Parts** These part numbers are widely available through Suzuki dealerships, online marketplaces (eBay, Amazon, RockAuto), and specialty auto parts stores. This makes sourcing the part convenient.

8. **Potential for Long-Term Use** If the switch is high-quality and properly installed, it can last for the lifetime of the vehicle, eliminating the need for future replacements.

---

1. **Age of the Vehicle** The 1991 Suzuki LT80 is an older model, and while the ignition switch itself may be reliable, other components (wiring, starter, or electrical system) could be worn out or degraded. This means the switch may not solve all issues if the underlying electrical system is failing.

2. **Potential for Counterfeit Parts** When purchasing online, there is a risk of receiving counterfeit or low-quality replicas, especially from unverified sellers. This can lead to premature failure or poor performance.

3. **Labor Costs (If Professional Installation)** While DIY installation is possible, if you lack mechanical experience, hiring a mechanic may incur additional labor costs, which could offset the savings of buying a part yourself.

4. **Limited Warranty** Aftermarket parts may not come with warranties, whereas OEM parts from a dealership might offer limited coverage. This means you could be responsible for any defects if they arise shortly after purchase.

5. **Compatibility with Modified Vehicles** If the LT80 has been modified (e.g., aftermarket alarms, security systems, or wiring changes), the new ignition switch may not integrate perfectly, potentially requiring additional adjustments.

6. **Time-Consuming Replacement** Replacing an ignition switch requires some disassembly of the steering column and dashboard, which can be time-consuming, especially for inexperienced DIYers. This may not be ideal if you need the vehicle operational quickly.

7. **Risk of Overpaying** Prices for these parts can vary widely depending on the seller. Some may charge premium prices for "new OEM" parts that are actually refurbished or used. Researching and comparing prices is essential to avoid overpaying.

8. **Potential for Additional Issues** If the ignition switch failure is symptomatic of a larger problem (e.g., a failing steering column, wiring harness damage, or a faulty starter), replacing just the switch may not resolve the root cause, leading to recurring problems.

Buying the Suzuki ignition switch (37110-40B00, 37110-40B01, 137, or 1991 LT80-compatible) is a practical and cost-effective solution for addressing ignition-related issues in your 1991 LT80. The pros such as compatibility, reliability, and ease of installation outweigh the cons for most owners, provided the part is sourced from a reputable supplier. However, it is crucial to consider the vehicle s overall condition, the quality of the part, and whether the issue is isolated to the switch or part of a larger problem.

If the ignition switch is the sole culprit behind your vehicle s issues, replacing it will likely restore functionality and improve safety. For those comfortable with basic mechanical work, DIY installation is a viable and economical option. If not, consulting a mechanic can ensure the job is done correctly.

---

1. **Verify the Part Number** Double-check that the part number matches your vehicle s exact requirements. Cross-reference with your Suzuki LT80 s manual or a trusted parts database (e.g., RockAuto, Haynes Manual) to avoid mismatches.

2. **Purchase from a Trusted Source** Buy the part from a reputable dealer, Suzuki-approved supplier, or a well-reviewed online retailer (e.g., Amazon, eBay with verified sellers). Avoid suspiciously cheap offers, as they may indicate counterfeit or low-quality parts.

3. **Consider OEM vs. Aftermarket** If budget allows, opt for an OEM part from a Suzuki dealership for guaranteed compatibility and warranty. Aftermarket parts can be equally reliable if sourced from brands with good reputations (e.g., Dorman, Bosch, or local Suzuki specialists).

4. **Inspect the Electrical System** Before replacing the switch, test the starter, wiring, and steering column for other potential issues. This can save time and money if the problem extends beyond the ignition switch.

5. **Follow Installation Guidelines Carefully** If attempting a DIY replacement, follow the manufacturer s instructions or a detailed online guide (e.g., YouTube tutorials for the LT80). Improper installation can lead to further damage or safety hazards.

6. **Test the Switch After Installation** Once installed, thoroughly test the ignition switch in all positions (OFF, ACC, RUN, START) to ensure it functions correctly. Listen for unusual noises or check for warning lights on the dashboard.

7. **Monitor for Recurring Issues** If the problem persists or new issues arise after replacement, consult a mechanic to diagnose whether the root cause has been addressed or if additional repairs are needed.

**Final Verdict:** The Suzuki ignition switch (37110-40B00/40B01 or equivalent) is a sound investment for restoring your 1991 LT80 s ignition system, provided you source the part carefully and address any underlying electrical issues. For most owners, the benefits of reliability, cost savings, and ease of replacement make it a worthwhile upgrade.
