This is the best shock in the industry, Its the shock we run on all of our Personal Bikes. Its a night and day difference from the oem shock. And if your pair it to the EXT Ferro its unbelievable! if we could go back and start our upgrade process over again the EXT suspension would be one of the first upgrades we would do!   The Arma MX is a direct bolt-on replacement for the Sur Ron Light Bee X , Talaria Sting and E-Ride Pro SS. No additional Hardware is needed, simply bolt-on and go.    Bike Fitment: Direct Bolt On - No additional parts necessary Talaria Sting MX5 Talaria Sting MX3 Talaria Sting mx4/R Surron Light Bee Segway X260 E-Ride Pro SS 1/2/3.0 Talaria XXX - it will be stiffer than your oem shock because there is no linkage. But it does fit! Throne Srpnt Rerode R1 79Bike Falcon Pro 79Bike Falcom GT Does not Fit 79 bike falcon m - you need extra shims to make it fit!   Engineered with performance and control as primary objectives, the shock structure has seen a redesign in order to be more robust. The Hydraulic Bottom-Out Circuit (HBC) has been enhanced with a wider range of adjustment, in order to prevent bottom-out issues, while allowing riders to use softer spring rates and providing excellent support and end stoke characteristics. The Arma MX includes the following features 4 way adjustable: LSC-HSC-LSR-HBC (Hydraulic Bottom-Out Control) High flow 29 mm main piston 24 mm valve piston 14 mm shaft (50% larger than most other coils on market to help deal with large side loading events) Engineered rebound circuit to separate bump and rebound oil flow – Ultra low-friction coating User adjustable HBC technology Very low reservoir pressure for maximum sensitivity  and low cavitation(55 PSI) Full custom hydraulic setup that is bike and rider specific for each shock Very low hysteresis for high dynamic response High turbulent flow for progressive dampening and mid stroke support Low friction seal Thinner bottom-out bumper and debris clearing washer New low profile rebound knob for easy spring swap Included with 1 light weight spring available in 400lb, 450lb, 500lb, 550lb or 600lbs (Lower options may be available upon request) Comes with specific mounting hardware for easy bolt in instillation.  *This is a special edition shock that will be built in limited runs.

The standard drop crown color is black. If you would like a different crown color, please include a note with your order at checkout. ③ Spring Weight RecommendationsFor 203mm Travel Fork (compatible with 19"/21" wheels): 45lbs spring – ≤100kg 60lbs spring – 100–130kg (ideal for heavy jumping) 45–60lbs progressive spring – 80–130kg For 228mm Travel Fork (compatible with 19"/21" wheels): 45lbs spring – ≤100kg 55lbs spring – 100–130kg ④ Performance Suspension System – Featuring a high-performance inverted oil-spring damping system, this fork offers multi-stage adjustability for high-speed compression, low-speed compression, rebound, and spring preload, ensuring optimal tuning across various riding styles and terrain types. ⑤ Built for Durability – The fork uses AL6061-T6 forged aluminum alloy for the bottom brackets and AL7075-T6 aluminum for the tubes. The spring wire is made from 55CRSI, engineered for longevity and performance in demanding off-road conditions. FEATURES: Center Distance: 750–800mm Main Piston Travel: 203–228mm Tube Diameter: ∅37mm Caliper Mount Spacing: 99.5mm Disc Brake Size: ∅220mm (Upgradeable) Damping System: Inverted Oil-Spring Adjustments: Multi-stage High-Speed Compression, Low-Speed Compression, Rebound, Spring Preload Materials: AL6061-T6 Forged Aluminum (Bottom), AL7075-T6 Aluminum (Tubes) Spring Wire: 55CRSI Triple Clamp: CNC Precision Machined  Fitment: E Ride Pro 3.0 / SR

NOTE: The spring preload is recommended to be around 10mm; excessive preload will lead to spring deformation, resulting in the spring side wear phenomenon. ① Advanced Shock Absorption - The RAB53RV rear shock absorber features an external nitrogen reservoir and a sophisticated oil-gas separation damping structure. Designed to provide superior shock absorption, it effectively reduces impact and enhances riding comfort across a wide range of conditions. ② Versatile Performance - Ideal for E-BIKES, bicycles, and off-road electric bikes, the RAB53RV is built to handle diverse terrains and challenging rides. It offers comprehensive adjustability with multi-stage rebound, high-speed compression, and low-speed compression damping settings. Customization options are available upon request. ③ Durable Construction - Constructed with AL6061-T6 forged aluminum for the upper mount and AL6061-T6 aluminum alloy for the main tube, this shock absorber ensures exceptional strength and durability. The 42CRMO main shaft and 55CRSI spring wire further enhance its robustness and reliability. ④ Precision Adjustments - Equipped with multi-stage rebound and compression damping adjustments, the RAB53RV allows you to fine-tune the shock absorber for your specific riding style. The C-ring retainer spring base ensures stability during rides, while the easy-to-remove spring design simplifies maintenance. ⑤ Enhanced Comfort - The shock absorber features a rubber bladder in the air chamber, reducing heat-induced damping fade and providing a finer response to small bumps. The low-speed compression damping controls the shock absorber's performance during gradual impacts like pedal strokes and rough terrain, while the high-speed compression damping handles sudden impacts and high-speed encounters, ensuring stability and control during intense riding moments. High and Low-Speed Compression Damping Explained: Low-Speed Compression Damping (LSC): This setting controls the shock absorber's response to gradual impacts and low-speed movements. It’s essential for reducing bounce and instability during everyday riding activities such as pedaling, climbing stairs, or traversing uneven surfaces. Proper adjustment of LSC enhances ride stability and comfort. High-Speed Compression Damping (HSC): This setting manages the shock absorber's response to rapid impacts and high-speed situations, such as drops or sudden bumps. It prevents the shock absorber from becoming too soft during intense impacts, maintaining control and stability to prevent loss of balance and potential accidents.

The Sirris Shock is designed to offer the maximum possible piston size and still fit within the stock linkage. Tolerances on each stock Ultra Bee vary. Light contact between spring OD and stock triangle may occur. We highly recommend our higher clearance triangle to prevent this. WARNING: Some aftermarket triangle links may have significant interference that could damage the shock and/or triangle. It’s important to check clearance as you assemble and cycle the suspension. Do not install Sirris shock if any interference is detected. Failure to properly install the shock with proper triangle can lead to a loss of control of the motorcycle which can result in SERIOUS INJURY OR DEATH.

Our new suspension version 2 is out now off of pre order and ready to be shipping This suspension is built for the Tuttio/Yozma and maybe the heybike (not tested yet), but can work on other bikes with adjustments. With more resistance on the forks and a little less height on the shock, we made the prefect balance of suspension from the front to the rear. Specs - Forks are 680mm and have 35lb springs Shock is 270mm / 650lbs  These are a huge upgrade from before and for and even lower price. SUSPENSION SHIPS NEXT DAY
