Review TRIUMPH Triple Frame Chassis Stpss Straight fits STREET 2017–2020

The Triumph Street Triple RS (model code 2071240) from the 2017 to 2020 generation represents a pinnacle of modern sportbike engineering, blending raw performance with refined precision in a compact, agile package. This model is built upon the iconic **STPS (Straight-Tube Parallel Twin) chassis**, a design philosophy that prioritizes rigidity, balance, and a neutral riding position, ensuring a direct connection between rider and machine. The frame itself is crafted from high-strength steel, featuring a **double-cradle construction** with a central backbone and reinforced subframes that deliver exceptional stiffness while maintaining a lightweight profile. The geometry is meticulously tuned for a sporty yet approachable stance, with a **38-degree head angle**, **105mm rake**, and a **1,400mm wheelbase**, striking an ideal balance between stability at speed and nimble cornering. The **STPS chassis** eliminates the need for complex suspension linkages, allowing for a cleaner, more aerodynamic design while enhancing durability particularly in high-stress riding scenarios.

Underpinning the frame is Triumph s **955cc parallel-twin engine**, a powerplant renowned for its smoothness, responsiveness, and reliability. The RS variant of the Street Triple is distinguished by its **full faired bodywork**, which not only enhances aerodynamics but also houses a **high-flow exhaust system** and **upgraded cooling components**, allowing the engine to operate at peak efficiency even under prolonged hard riding. The **liquid-cooled** inline twin produces a linear, torque-rich power delivery, with a rev-happy nature that rewards the rider with a thrilling 105 hp and 72 lb-ft of torque delivered through a **six-speed transmission** with a slick-shifter for effortless gear changes. The engine s compact size and balanced weight distribution contribute to the Street Triple RS s legendary **neutral handling**, making it equally at home on twisty backroads or open highways.

The suspension setup on the 2071240 model is a refined blend of performance and comfort, featuring **WP XACT inverted front forks** with adjustable preload, compression, and rebound damping, paired with a **WP rear monoshock** that offers similar levels of customization. The **31mm front forks** and **120mm rear shock** work in tandem with **cast aluminum wheels** (17-inch front, 18-inch rear) and **high-performance Pirelli Diablo Rosso III tires** to provide a responsive yet forgiving ride. The braking system is equally impressive, with **dual 320mm front discs** and **single 240mm rear disc**, both paired with **Brembo radial-mount calipers** that deliver progressive, fade-resistant stopping power. The **Triumph TFT (Triumph Fuel Injection) system** ensures precise fuel delivery, while the **digital instrument cluster** offers real-time data on speed, RPM, fuel range, and traction control settings, empowering the rider with actionable feedback.

The Street Triple RS s **full fairing** isn t just for aesthetics it s engineered to reduce drag and improve stability at high speeds, making it one of the most aerodynamic bikes in its class. The **carbon-fiber body panels** and **polycarbonate windscreen** are not only lightweight but also durable, designed to withstand the rigors of daily riding while maintaining a sleek, aggressive aesthetic. Inside, the ergonomics are tailored for sporty riding, with an **upright handlebar position**, **ergonomic grips**, and a **low seat height** (29.9 inches) that encourages an engaged, forward-leaning posture. The **blacked-out aluminum footpegs** and **adjustable seat** (available in multiple heights) further customize the riding position, ensuring comfort and control whether cruising or pushing the limits.

Beyond its performance credentials, the Triumph Street Triple RS is built to last, with a **durable paint finish** (available in a range of premium colors) and **high-quality materials** throughout. The bike s **maintenance-friendly design** thanks in part to its modular components makes it a practical choice for enthusiasts who appreciate both performance and longevity. Whether you re a seasoned rider seeking a track-ready machine or a newcomer to sportbikes looking for a versatile, high-performance companion, the 2017-2020 Triumph Street Triple RS (2071240) delivers an unmatched blend of **precision, power, and purity**, embodying Triumph s commitment to crafting bikes that are as much about the joy of riding as they are about raw capability.

### **Pros and Cons of Buying a Triumph Street Triple (2017 2020, Frame Chassis STPS, 17-20 Model Year)**

1. **Performance and Power**

The Triumph Street Triple (STPS) is a high-performance naked bike with a 675cc parallel-twin engine producing around **130 135 hp** and **80 85 lb-ft of torque**, making it one of the quickest production naked bikes in its class. The STPS version includes a **full exhaust system, high-flow airbox, and revised ECU tuning**, which enhances throttle response and top-speed capability compared to the standard model.

2. **Lightweight and Agile Handling**

The **aluminum frame chassis** keeps the bike relatively light (around **420 430 lbs fully fueled**), improving maneuverability and making it easier to handle in city traffic and on twisty roads. The **telescopic front fork and rear monoshock suspension** provide a balanced ride, though some riders may find it slightly firm for long-distance comfort.

3. **Modern Technology and Ergonomics**

The Street Triple features **Triumph s Triplex fuel injection system**, which ensures smooth power delivery and better fuel efficiency than carbureted bikes. The **ergonomics are well-tuned**, with an upright riding position that reduces fatigue on long rides. The **digital instrument cluster** (with options for analog gauges) provides real-time data on speed, RPM, fuel, and more.

4. **Customization Potential**

The STPS is a popular choice for customization due to its **aftermarket-friendly design**. Owners can easily upgrade components like **exhausts, suspension, brakes, and handlebars** to tailor the bike to their preferences. The **removable fairings** allow for further personalization, whether for a sportier look or a more aggressive stance.

5. **Reliability and Maintenance**

Triumph s parallel-twin engines are known for their **durability and ease of maintenance**. The **dry-sump lubrication system** helps prevent oil starvation in aggressive riding, and the **air-cooled design** reduces the risk of overheating. Many owners report **few major issues** if routine maintenance is followed, though some have experienced **chain tensioner failures** or **throttle body carbon buildup** over time.

6. **Resale Value and Community**

The Street Triple, especially the STPS variant, holds its value well due to its **strong reputation for performance and styling**. There is also a **large and active owner community**, making it easier to find parts, modifications, and riding groups.

7. **Sporty Yet Practical**

While it s a sporty bike, the Street Triple isn t overly aggressive, making it suitable for **commuting, weekend rides, and track days**. The **naked design** allows for easy access to the seat and footpegs, and the **moderate weight** makes it manageable for riders of varying experience levels.

---

1. **Vibration and NVH (Noise, Vibration, Harshness)**

The **parallel-twin engine** is notorious for **mid-range vibrations**, particularly at higher RPMs. While Triumph has improved this in later models, some riders still find the **seat and handlebars shaking** under sustained throttle. The **naked design** also means **wind noise** is more noticeable than on fully faired bikes.

2. **Suspension Limitations**

The **stock suspension** is tuned for sporty handling rather than comfort. The **front fork and rear shock** can feel **too firm for long-distance riding**, leading to fatigue on rough roads. Upgrading to **aftermarket suspension** (e.g., hlins, Showa) is common but adds cost.

3. **Braking Capabilities**

While the **Brembo front brake system** (on later models) is strong, some riders find the **rear brake** insufficient for hard stops, especially in wet conditions. Upgrading to **aftermarket rotors and pads** (e.g., EBC, Brembo) is often recommended for better stopping power.

4. **Fuel Efficiency**

The STPS is **not the most fuel-efficient bike** in its class, averaging around **35 40 mpg** in real-world conditions. The **high-performance exhaust and tuning** contribute to slightly worse mileage compared to standard Street Triples or competitors like the Yamaha MT-07.

5. **Maintenance Costs**

While the engine is reliable, **aftermarket parts and modifications** can add up. Components like **exhausts, suspension, and brakes** are often upgraded, and **Triumph s service culture** can be inconsistent depending on the dealer. Some riders report **higher maintenance costs** than expected, especially if DIY repairs are not an option.

6. **Comfort for Tall Riders**

The **stock seat and ergonomics** may not suit **taller riders (6 )** comfortably. The **upright position** is great for visibility but can lead to **lower back fatigue** on long rides. Adjustable seats and handlebars can help, but some may need to invest in aftermarket solutions.

7. **Resale Depreciation (Compared to Some Rivals)**

While the Street Triple retains value well, some **more modern bikes (e.g., 2021 models or competitors like the Yamaha MT-09 or Kawasaki Ninja 400)** may depreciate slightly slower. However, the **STPS remains a strong used purchase** due to its performance and desirability.

8. **Noise Levels**

The **naked design and high-revving engine** make the Street Triple **loud**, especially at highway speeds. While this is part of its charm, it may not be ideal for **urban commuting** where noise restrictions apply.

---

The **Triumph Street Triple (STPS, 2017 2020)** is an **excellent choice for riders** who prioritize **performance, agility, and customization** over pure comfort or fuel efficiency. It delivers **strong power, engaging handling, and a sporty yet practical riding experience**, making it ideal for **weekend adventures, track days, and commuting**.
