Scarlet Racing Suspension: A Technical Review of Remote Reservoir Mono Shocks for Dual-Purpose Bikes

| Red Scarlet Monoshock |
For enthusiasts of dual-purpose motorcycles like the Yamaha WR 155 R, Honda CRF 150L, and Kawasaki KLX 150, the suspension system is often the first point of discussion when it comes to performance modifications. These bikes are celebrated for their versatility, but "versatile" often means the factory suspension is a compromise—adequate for the road but sometimes lacking the sophisticated damping required for serious off-road terrain.
In recent years, the aftermarket industry has seen a surge in high-performance options. One of the most prominent brands in this space is Scarlet Racing. Known for combining CNC precision with accessible pricing, the Scarlet Racing Remote Reservoir Mono Shock has become a staple for riders looking to bridge the gap between hobbyist riding and professional performance.
The Engineering Behind Scarlet Racing’s Remote Reservoir
The primary enemy of any suspension system is heat. When a shock absorber works rapidly over corrugated roads or rocky trails, the friction of the piston moving through the oil generates significant thermal energy. In a standard shock, this heat causes the oil to thin out, leading to "fade," where the shock loses its ability to dampen effectively.
Scarlet Racing addresses this by using a Remote Reservoir (Tabung Terpisah) system. This design offers several technical advantages:
Increased Oil Volume: More oil means the system takes much longer to heat up, maintaining performance during long endurance rides.
Nitrogen Gas Separation: By keeping the oil and gas separated by a bladder or piston within the Scarlet reservoir, the shock provides a consistent feel and prevents "foaming" of the oil.
Superior Cooling: The external aluminum reservoir is exposed to more airflow than a standard internal shock, helping dissipate heat rapidly.
Technical Specifications: The Scarlet Standard
When evaluating a mono shock for heavy-duty export and use, the internal dimensions are just as important as the brand name. Scarlet Racing has engineered this unit with specific metrics to ensure it can handle the "G-outs" and sudden impacts common in international trail riding.
1. Shaft and Spring Durability
The 14mm main shaft found in the Scarlet Racing series is a significant upgrade over many budget alternatives. A thicker shaft provides the lateral strength needed to prevent bending during hard landings. Complementing this is a 12mm coil spring, which Scarlet has tuned to provide a "plush" initial stroke for small gravel, while maintaining enough "bottoming resistance" for large jumps or obstacles.
2. CNC-Machined Components
One of the hallmarks of Scarlet Racing is the use of CNC (Computer Numerical Control) machining. The bushings and mounting points are not cast; they are carved from high-grade blocks of metal. This ensures that the shock integrates perfectly with the bike's linkage, reducing friction and preventing premature wear on the motorcycle's frame.
Mastering the Art of Adjustment: The 46-Click System

The ability to "tune" a suspension is what separates a basic replacement from a professional performance upgrade. Scarlet Racing equips this unit with a comprehensive 46-click adjustment system, categorized into two main functions:
Compression Adjuster (22 Clicks)
Located on the Scarlet remote reservoir, the compression dial controls the resistance when the shock is pushed upwards.
Soft Settings: Ideal for low-speed technical trails where you want the bike to track over rocks smoothly.
Stiff Settings: Necessary for high-speed "whoops" or when carrying a passenger to prevent the bike from wallowing or bottoming out.
Rebound Adjuster (24 Clicks)
The rebound adjustment is perhaps even more critical for safety. It controls the speed at which the shock extends back to its original length. If the rebound is too fast, the rear of the bike will kick up like a pogo stick. With Scarlet’s 24 clicks of rebound adjustment, riders can find the "sweet spot" where the rear tire stays firmly planted on the ground, providing better traction and cornering control.
Performance in Different Environments

The Daily Commute
On asphalt, the goal is vibration isolation. A well-tuned Scarlet Racing shock transforms a vibratory dirt bike into a smooth commuter. By adjusting the preload and backing off the compression, riders can eliminate the jarring sensation of potholes and speed bumps, making the bike much more "civilized" for city use.
Hard Enduro and Trail Riding
Off-road, the strength of the Scarlet build becomes apparent. The bike feels more "composed." When landing from a jump, the shock absorbs the energy progressively rather than slamming into the rubber bump stop. This not only protects the rider’s spine but also reduces the long-term stress on the motorcycle’s subframe.
Maintenance and Longevity for Export Units
Any performance component requires care to maintain its efficiency. For Scarlet Racing shocks used in muddy or dusty conditions, regular maintenance is key:
Cleaning: Always wipe down the 14mm shaft after a muddy ride. Grit can tear the oil seals if left to dry.
Warna (Aesthetics): Scarlet provides these units in Black, Red, and Yellow. These are high-quality finishes, but regular cleaning ensures the colors stay vibrant against the elements.
Linkage Greasing: A great shock cannot perform well if the bike's linkage bearings are seized. Ensure the entire rear suspension system is well-lubricated to get the most out of your Scarlet upgrade.
International Availability and Export Pricing
As the global market for dual-purpose bikes expands, high-quality components from Southeast Asia are becoming increasingly popular in North America, Europe, and Australia. Scarlet Racing is a prime example of a brand that offers professional-grade features at a price point that makes sense for international enthusiasts.
Pricing and Shipping Considerations
For international buyers looking to source this specific upgrade, the base price from our inventory is $119.00 USD. However, it is vital to understand the logistics of international procurement:
Export Price: $119.00 USD (Brand New, Original Scarlet Racing).
Shipping Policy: Please note that the price of $119.00 USD does not include international shipping costs (postage).
Global Delivery: Shipping rates vary significantly based on the destination country and the weight of the package. Each country may also apply its own import duties or local taxes upon arrival.
Compatibility: This Scarlet unit is designed for the WR 155, CRF 150L, and KLX 150 models.
Final Thoughts
Upgrading to a Scarlet Racing Remote Reservoir Mono Shock is one of the most impactful modifications a rider can make. It enhances safety, improves comfort, and allows the motorcycle to reach its full potential off-road. With its 14mm as tengah, 46-click adjustability, and robust CNC build, it represents one of the best value-for-money upgrades on the market today.
