Review BOYESEN Super Stock Reeds Yamaha Viper fits MOUNTAIN SRX600 SRX700 SX

The Boyesen 540SF1 Reeds is a meticulously engineered, high-performance aftermarket exhaust system designed to elevate the sound, efficiency, and aesthetics of Yamaha s SRX600, SRX700, and SXV700MH, as well as the SRX Viper Mountain models. Crafted from premium 304 stainless steel, this system features a bold, aggressive dual-tip design that not only enhances the bike s visual appeal but also delivers a deep, resonant exhaust note that transforms the stock growl into a more dynamic, sporty growl. The 540SF1 Reeds incorporates a high-flow, high-temperature catalytic converter and a carefully tuned muffler system that optimizes exhaust flow while maintaining compliance with emissions standards, ensuring a balanced performance boost without sacrificing reliability. The system s dual-tip design, with its wide, flared outlets, is engineered to reduce backpressure, allowing the engine to breathe more freely and unlock subtle power gains, particularly in the mid-to-high RPM range. The exhaust s polished finish and sleek, aerodynamic contours complement the aggressive styling of Yamaha s adventure and dual-sport bikes, making the 540SF1 Reeds an ideal choice for riders seeking both performance and a distinctive, eye-catching upgrade. Whether cruising on paved roads or tackling off-road trails, this exhaust system delivers a refined yet assertive exhaust tone that enhances the riding experience while turning heads with its bold, modern aesthetic.

### **Pros and Cons of Buying Different Yamaha Motorcycles**

#### **1. Boyesen 540SF (Custom Cruiser)**

- **Unique Design:** The Boyesen 540SF is a highly customized version of the Yamaha V Star 950, offering a distinctive, low-slung, and aggressive cruiser look with a long-tail design.

- **Powerful Engine:** Retains the stock 944cc V-twin engine from the V Star 950, which provides strong low-end torque and smooth power delivery, making it suitable for both highway cruising and urban riding.

- **Comfortable for Long Rides:** The low seat height and relaxed ergonomics make it comfortable for riders who prefer a laid-back posture, ideal for long-distance touring.

- **Custom Modifications:** Comes with aftermarket upgrades such as a custom paint job, chrome accents, and performance exhaust, enhancing its aesthetic appeal.

- **Good Handling for a Cruiser:** Despite its heavy weight, the 540SF handles better than many stock cruisers due to the V Star s stable chassis and suspension tuning.

- **Heavy Weight:** The bike weighs around 600 650 lbs (270 295 kg), which can make it feel sluggish in tight corners and require more effort to maneuver, especially at low speeds.

- **Limited Stock Availability:** Boyesen builds a limited number of custom bikes, so availability may be restricted, and lead times can be long.

- **Higher Cost:** Due to its custom nature and aftermarket modifications, the 540SF is significantly more expensive than a stock V Star 950, often priced in the range of $15,000 $20,000 .

- **Maintenance Complexity:** Custom bikes may require specialized mechanics familiar with the modifications, increasing maintenance costs over time.

- **Not Ideal for Sporty Riding:** The heavy weight and upright riding position make it less suitable for aggressive cornering or track use.

#### **2. Yamaha SRX600 (Standard Adventure Bike)**

- **Versatile Riding Position:** The SRX600 offers a comfortable, upright riding position that is suitable for both city commuting and light off-road adventures.

- **Lightweight and Maneuverable:** Weighing around 400 lbs (180 kg), it is easier to handle than heavier adventure bikes, making it ideal for urban riding and parking in tight spaces.

- **Decent Engine Performance:** The 599cc parallel-twin engine delivers adequate power (50 hp) and torque (43 lb-ft), providing a balanced mix of throttle response and efficiency.

- **Affordable:** Compared to larger adventure bikes, the SRX600 is relatively inexpensive, typically priced around $6,000 $7,500 new.

- **Good Fuel Economy:** The engine is fuel-efficient, making it cost-effective for daily commuting and short trips.

- **Reliable Yamaha Build Quality:** Yamaha is known for durable and low-maintenance engines, reducing long-term repair costs.

- **Limited Off-Road Capability:** While it has some adventure features (e.g., knobby tires, raised seat), it is not as capable as full-fledged dual-sport or adventure bikes (e.g., Yamaha T n r or Suzuki V-Strom) for serious off-roading.

- **Basic Suspension:** The suspension is tuned for comfort rather than aggressive off-road use, so it may feel soft on rough terrain.

- **Outdated Design:** The SRX600 is based on an older platform (introduced in 2011), and its styling feels dated compared to newer adventure bikes.

- **Weaker Top-End Power:** The engine lacks the high-revving excitement of sportier bikes, and the power delivery is linear but not thrilling.

- **Limited Aftermarket Support:** Compared to popular bikes like the Yamaha MT-07 or Honda CBR, the SRX600 has a smaller aftermarket community, limiting customization options.

---

#### **3. Yamaha SRX700 (Standard Adventure Bike)**

- **Improved Engine:** The SRX700 upgrades the engine to a 689cc parallel-twin (same as the MT-07), increasing power to 55 hp and torque to 47 lb-ft, making it more spirited than the SRX600.

- **Better Handling:** The slightly longer wheelbase and refined chassis offer improved stability and cornering compared to the SRX600.

- **More Adventure Features:** Retains the adventure-oriented styling of the SRX600 but with slight refinements, such as better ergonomics and a more modern look.

- **Reliable and Low-Maintenance:** Yamaha s parallel-twin engines are known for durability, and the SRX700 follows this tradition.

- **Good for Beginners:** The comfortable riding position and manageable power make it a good choice for new riders or those transitioning from smaller bikes.

- **Still Not a True Adventure Bike:** Like the SRX600, it lacks the full off-road capability of bikes like the Yamaha T n r or Royal Enfield Himalayan.

- **Heavy for Its Class:** Weighs around 450 470 lbs (200 213 kg), which is heavier than sportier bikes but still manageable for urban riding.

- **Limited Aftermarket:** The SRX700 has a smaller aftermarket presence compared to sport or naked bikes, limiting upgrade options.

- **Outdated Platform:** While an improvement over the SRX600, it is still based on an older chassis and lacks the modernity of newer adventure bikes.

- **Higher Price Than SRX600:** Typically priced around $7,000 $8,500, making it more expensive than the SRX600 without a significant leap in capability.

#### **4. Yamaha SXV70MH (Dual-Sport Adventure Bike)**

- **True Dual-Sport Capability:** The SXV70MH is Yamaha s entry-level dual-sport bike, designed for both on-road and off-road use. It features a knobby tire, long-travel suspension, and a rugged chassis.

- **Lightweight and Maneuverable:** Weighs around 350 370 lbs (160 170 kg), making it easy to handle on trails and in tight spaces.

- **Decent Engine Performance:** The 689cc parallel-twin engine (same as the MT-07) delivers 55 hp and 47 lb-ft of torque, providing enough power for both on-road and light off-road adventures.

- **Affordable Adventure Option:** Typically priced around $7,000 $8,500, it offers adventure capabilities at a lower cost than full-fledged adventure bikes.

- **Reliable and Simple:** Yamaha s parallel-twin engines are known for reliability, and the SXV70MH is designed for durability with minimal maintenance requirements.

- **Good for Beginners:** The upright riding position and manageable power make it accessible for new riders or those exploring dual-sport riding.

- **Basic Off-Road Performance:** While capable of light trails, it is not as rugged as dedicated dual-sport bikes (e.g., Yamaha WR250R or Honda CRF250L) or full adventure bikes.

- **Comfortable Only for Short Trips:** The suspension is tuned for off-road use, which can make it less comfortable for long on-road rides compared to adventure bikes with softer suspension.

- **Limited Top Speed:** The engine is not tuned for high-speed cruising, with a top speed around 100 mph (160 km/h), which may feel slow for highway riding.

- **Narrow Tire:** The knobby tire is not ideal for high-speed on-road use, as it provides poor wet-weather grip and can be noisy on pavement.

- **Less Refined Than Adventure Bikes:** The ergonomics and riding position are less optimized for long-distance comfort compared to bikes like the Yamaha T n r or Royal Enfield Himalayan.

---

#### **5. Yamaha Viper Mountain (Dual-Sport Adventure Bike)**

- **True Adventure Capability:** The Viper Mountain is Yamaha s flagship dual-sport bike, designed for serious off-road adventures while maintaining on-road usability. It features a long-travel suspension, knobby tires, and a rugged chassis.

- **Powerful Engine:** The 689cc parallel-twin engine (same as the MT-07) delivers 55 hp and 47 lb-ft of torque, providing ample power for both on-road and off-road use.

- **Long-Travel Suspension:** The Viper Mountain comes with a 5.9-inch front fork and a 6.3-inch rear shock, allowing it to handle rough terrain comfortably.

- **Versatile Tires:** Equipped with a dual-sport tire (e.g., Michelin Wild Rider or Bridgestone Dueler) that offers a good balance of on-road and off-road grip.

- **Comfortable for Long Rides:** The ergonomics are more refined than the SXV70MH, with a slightly more upright but still flexible riding position.
