Review BUELL New Inline Tank Fuel Filter Oem fits XB9 EFI CR 2008–2010

The **Buell XB9/XB12R 388cc High-Flow Performance (HFP) inline tank with Electronic Fuel Injection (EFI) and 1125R CR fuel filter** represents a meticulously engineered upgrade designed to elevate the performance, reliability, and aesthetics of Buell s iconic inline-six motorcycles, particularly the XB9 and XB12R models from the 2008 2010 era. This premium aftermarket kit is crafted to address the unique demands of Buell s high-revving, torque-rich inline-six engine while ensuring seamless integration with the factory EFI system. The **388cc inline tank** is a meticulously fabricated replica of the original, but with refined details such as precision-machined fuel lines, high-quality anodized aluminum construction, and a sleek, aerodynamic profile that enhance both form and function. The tank s integrated **1125R CR fuel filter** is a standout feature, offering superior filtration with a replaceable cartridge that effectively removes contaminants, ensuring cleaner fuel delivery to the EFI system and prolonging the life of critical engine components. This filter is specifically engineered to handle the demands of high-flow applications, reducing the risk of clogging and maintaining optimal fuel pressure even under heavy throttle inputs. The **HFP designation** underscores the kit s performance-oriented design, with upgraded fuel delivery pathways that minimize turbulence and maximize efficiency, allowing the engine to breathe more freely while reducing vapor lock and fuel starvation at high RPMs. Whether installed on a classic XB9 or a more powerful XB12R, this inline tank system provides a seamless blend of heritage styling and modern engineering, catering to both purists who appreciate Buell s signature aesthetics and performance enthusiasts seeking measurable gains in power and reliability. The attention to detail extends to the **CR (Cleaner Running) specification**, which incorporates advanced filtration media to further refine fuel quality, contributing to a cleaner-burning engine and reduced emissions. For riders who demand the best from their Buell, this kit is an essential upgrade combining heritage design with cutting-edge technology to deliver a refined, high-performance fueling solution that turns heads and turns heads on the track.

### **Buell XB9/XB12R (2008-2010) Pros and Cons**

1. **Lightweight and Agile** The XB9 (388cc) and XB12R (1254cc) are among the lightest production bikes in their classes, making them highly maneuverable and responsive. The XB12R, in particular, is a rare inline-four that weighs significantly less than competitors like the Honda CBR600RR or Suzuki GSX-R600.

2. **Superbike-Level Handling** The bikes feature advanced chassis geometry, including a full carbon fiber frame (XB12R) and a steel trellis frame (XB9), which contribute to razor-sharp cornering and precise feedback. The XB12R s inline-four engine is also tuned for high-revving performance, with a top speed around 160 mph.

3. **Track-Oriented Design** Buell s focus on track performance means these bikes have aggressive suspension tuning, lightweight components, and a low seat height, making them ideal for racetrack use. The XB12R s engine is particularly well-suited for high-RPM riding, with a rev limit around 14,000 RPM.

4. **Fuel Injection and Reliability** Both models use Buell s EFI system, which is reliable and provides consistent power delivery. The XB12R s inline-four is known for durability, though it requires more maintenance than a parallel-twin due to its complexity.

5. **Unique Aesthetic and Brand Appeal** Buell bikes have a distinctive, aggressive look that appeals to enthusiasts who prefer a sporty, track-focused design over more conventional cruisers or naked bikes.

6. **Aftermarket Support** While not as extensive as Honda or Yamaha, there is a dedicated aftermarket community for Buell bikes, with parts available for suspension, exhaust, and engine modifications.

---

1. **High Maintenance Costs** The inline-four engine on the XB12R is more complex than a parallel-twin, requiring more frequent oil changes, valve adjustments, and potential timing chain replacements. The XB9 s single-cylinder engine is simpler but still demands regular upkeep.

2. **Limited Comfort for Long Rides** The bikes are designed for track use, with a stiff, aggressive riding position that can lead to fatigue on long highway rides. The XB12R s seat is particularly hard, and the ergonomics are not ideal for cruising.

3. **Fuel Efficiency** Neither bike is fuel-efficient. The XB9 gets around 50-60 mpg, while the XB12R averages 35-40 mpg, making them expensive to run compared to smaller or more efficient bikes.

4. **Reliability Concerns** While the XB12R s engine is robust, some owners report issues with the EFI system, throttle body, and suspension components over time. The XB9 s single-cylinder engine is more reliable but lacks the power of modern parallel-twins.

5. **Discontinued Model** Buell was acquired by Harley-Davidson in 2010, and production of the XB9/XB12R ended shortly after. This means parts and service can be harder to find, and long-term support may be limited.

6. **Resale Value** Buell bikes, especially older models, hold their value poorly compared to more popular brands like Honda or Yamaha. The XB12R is rare, but its niche appeal may not translate to strong resale prospects.

7. **Weight Distribution** While the bikes are lightweight, the XB12R s engine placement can make them slightly top-heavy at high speeds, affecting stability in aggressive riding.

8. **Limited Practicality** The bikes lack storage, wind protection, and comfort features that make them less suitable for daily commuting or touring.

The Buell XB9/XB12R (2008-2010) are exceptional track-focused bikes that excel in handling, agility, and high-revving performance. They are ideal for riders who prioritize speed, precision, and a sporty riding experience over comfort or practicality. However, their high maintenance costs, limited comfort, and niche appeal make them less suitable for casual riders or those seeking a versatile daily bike.

The **XB12R** is the more powerful and desirable of the two, offering a rare inline-four experience with superbike-like handling, but it requires significant investment in upkeep. The **XB9** is a more affordable option with a simpler engine, though it lacks the power and complexity of the XB12R.

---

- **Buy if:** You are an experienced rider who prioritizes track performance, lightweight handling, and a high-revving engine. You are prepared for higher maintenance costs and willing to accept the bike s limitations for comfort and practicality. The XB12R is the better choice if you want more power, while the XB9 is a more budget-friendly alternative.

- **Avoid if:** You need a bike for daily commuting, long rides, or casual cruising. You prefer a more reliable, lower-maintenance engine (like a parallel-twin) or a bike with better resale value. You are not comfortable with the aggressive riding position or the bike s lack of storage/wind protection.

- For track-focused inline-four performance: **Honda CBR600RR** (more reliable, better support) or **Suzuki GSX-R600** (similar handling, better parts availability).

- For lightweight sportbikes: **Yamaha R3** or **Kawasaki Ninja 400** (more modern, better fuel efficiency).

- For Buell enthusiasts: Consider a **Buell Blast 900** (if available) for a more practical yet still sporty experience.

Ultimately, the Buell XB9/XB12R are **specialty bikes** best suited for riders who appreciate their unique characteristics and are willing to trade off comfort and practicality for pure performance.
