Review HONDA Idler Gear fits XR650L 2017

The **Honda 28134-MAN-690 2017 XR650L Idler Gear (B4309)** is a precision-engineered component designed specifically for Honda s legendary **2017 XR650L**, a dual-sport motorcycle celebrated for its rugged versatility, off-road prowess, and adaptability to both trail and street riding. This idler gear, part of the motorcycle s drivetrain system, plays a critical role in maintaining smooth and efficient power transfer from the clutch to the transmission, ensuring optimal shifting performance and minimizing wear on the primary chain and sprockets. Crafted from high-quality **steel alloy**, the idler gear is heat-treated and machined to Honda s exacting standards, guaranteeing durability, resistance to deformation, and longevity even under the demanding conditions of off-road riding, where impacts, vibrations, and heavy loads are common. Its **B4309 designation** confirms compatibility with the 2017 model year, aligning perfectly with the XR650L s **649cc parallel-twin engine**, which delivers a balanced blend of torque and responsiveness. Whether tackling rocky trails, navigating technical singletrack, or cruising on paved roads, this idler gear ensures reliable operation, reducing the risk of chain slippage or premature wear on the primary drive system. For riders who demand performance without compromise, this genuine Honda replacement part is an essential upgrade or maintenance solution, restoring factory precision and extending the lifespan of the drivetrain. Proper installation, along with regular chain and sprocket maintenance, will further enhance the XR650L s reliability, making it a must-have accessory for owners seeking to preserve their bike s original performance and handling characteristics.

### **Pros and Cons of buying a Honda 2017 XR650L with Idler Gear (Part Number: B4309)**

1. **Reliability and Durability** Honda s XR650L is widely regarded as one of the most durable and dependable dual-sport motorcycles. The 650cc parallel-twin engine is known for its longevity, often exceeding 20,000 miles with proper maintenance. Many owners report minimal major issues if serviced regularly.

2. **Proven Engine and Transmission** The 650cc engine is a well-tested design with a reputation for smooth power delivery, good low-end torque, and efficient fuel consumption. The 6-speed transmission is robust, and the clutch (if in good condition) is reliable.

3. **Off-Road Capability** The XR650L is designed for adventure riding, with a sturdy frame, long-travel suspension (front 120mm, rear 110mm), and knobby tires that perform well on both pavement and trails. Its lightweight (around 430 lbs wet) makes it agile for off-road use.

4. **Modular and Upgradable** Honda s modular design allows for easy upgrades, such as swapping out the stock engine for a more powerful kit (e.g., 750cc or 800cc conversions), upgrading suspension, or replacing the stock exhaust with aftermarket options. The idler gear (B4309) is a common upgrade for better chain tension and durability, reducing wear on the sprocket and chain.

5. **Resale Value** Honda dual-sports hold their value reasonably well, especially well-maintained examples. The XR650L is no exception, making it a practical choice if you plan to sell it later.

6. **Fuel Efficiency** The XR650L averages around 40-50 mpg on mixed riding, which is excellent for a dual-sport bike. This makes it cost-effective for long-distance touring or weekend adventures.

7. **Comfortable for Long Rides** The ergonomics are well-balanced, with a relaxed riding position that reduces fatigue on extended trips. The seat is comfortable, and the handlebars are adjustable, accommodating a range of rider sizes.

8. **Aftermarket Support** There is a strong aftermarket community for the XR650L, with availability of parts, accessories, and performance upgrades. This includes everything from suspension kits to engine modifications.

9. **Low Maintenance Costs** Compared to some other adventure bikes, the XR650L has relatively low running costs. Regular oil changes, chain maintenance, and basic tune-ups keep it running smoothly without expensive repairs.

10. **Versatility** The bike can handle a variety of terrains, from dirt trails to gravel roads and light pavement, making it a versatile choice for riders who enjoy variety.

1. **Stock Suspension Limitations** While the suspension is adequate for light off-road use, it is not as advanced as modern adventure bikes (e.g., BMW GS, KTM 790 Adventure). The front fork (WP XACT) and rear shock (WP) can feel stiff or bottom out on rough terrain, especially if the rider is heavier. Upgrading to aftermarket suspension (e.g., hlins, Showa) is recommended for serious off-road use.

2. **Stock Tires Are Basic** The stock tires (e.g., Michelin Wild Rider or Bridgestone Dueler) are decent but not high-performance. For aggressive off-roading, upgrading to more aggressive tires (e.g., Maxxis Rekon, Michelin Wild Rider XCR) is advisable. This adds to the initial cost.

3. **Braking Performance** The stock braking system (single disc at the front, drum at the rear) is adequate for light use but lacks the stopping power of modern dual-sport bikes with dual-disc setups. Upgrading to a front disc brake (e.g., Brembo) or a rear disc brake can significantly improve safety.

4. **Stock Exhaust Restrictions** The stock exhaust is restrictive and can limit top-end power. While not a dealbreaker, upgrading to a high-flow aftermarket exhaust (e.g., Akrapovic, Speed Easy) can improve throttle response and sound.

5. **Clutch Wear** The stock clutch can wear out over time, especially if the bike is ridden aggressively or in wet conditions. Replacing the clutch (and possibly the flywheel) is a common mid-life expense. Some owners opt for a multi-plate clutch upgrade for better durability.

6. **Fuel Tank Capacity** The 6.8-gallon tank is adequate for short trips but can be limiting for long-distance adventures. Carrying extra fuel or upgrading to a larger tank (e.g., 7.5 gallons) is a consideration for serious riders.

7. **Stock Seat Comfort** While the seat is comfortable for short rides, it can become uncomfortable on long trips. Upgrading to a more supportive seat (e.g., Ergon, Tourmaster) is a common modification.

8. **Electronics and Tech** The XR650L lacks modern tech features like traction control, ABS, or advanced instrumentation. While this keeps costs low, it also means less safety assistance for riders pushing the bike s limits.

9. **Resale Depreciation** Like most motorcycles, the XR650L depreciates over time. However, well-maintained examples retain value better than neglected ones. If you plan to keep it long-term, this is less of an issue.

- **Chain and Sprocket Wear** The stock chain and sprocket (especially if the idler gear is missing or worn) can cause excessive wear. The B4309 idler gear is a good upgrade to reduce chain slippage and extend component life.

- **Suspension Leaks** Fork seals and rear shock seals can leak over time, requiring replacement.

- **Engine Wear** If the bike has high mileage (e.g., 15,000 miles), check for signs of piston ring wear, valve train issues, or oil leaks.

- **Frame Cracks** Rare but possible, especially if the bike has been dropped or ridden aggressively. Inspect the frame for cracks or welds.

---

The **2017 Honda XR650L with an upgraded idler gear (B4309)** is an excellent choice for riders seeking a **reliable, versatile, and affordable** dual-sport motorcycle. Its **proven engine, durability, and off-road capability** make it a strong contender for adventure riding, commuting, or weekend trips. The idler gear upgrade is a smart investment, as it **reduces chain wear, improves tension, and extends the life of the sprocket and chain**, which are common failure points on stock XR650Ls.

However, **stock components like suspension, brakes, and tires may require upgrades** for serious off-road use or long-distance comfort. Buyers should **budget for common maintenance items** (clutch, chain, tires, suspension) and **inspect the bike thoroughly** for wear and tear before purchasing.

If you prioritize **reliability, simplicity, and a balance of on-road and off-road performance**, the XR650L is a **solid choice**. For riders who want **more advanced features, power, or tech**, newer adventure bikes (e.g., BMW GS 1250, KTM 790 Adventure, or Royal Enfield Super Meteor) may be worth considering but they come with higher costs and complexity.

---
