Upgrade the heart of your electric dirt bikes suspension with the FastaceBDA53RC, a premium, threewaydamped rear shock engineered specifically for hightorque emoto platforms such as the SurronLight Bee, TalariaXXX / MX3 / MX4 / MX5, and ErideProSS / SR. Riders who demand sharper handling, better bottomout resistance, and maximum traction during hard launches, trail chatter, or freestyle sessions will find this shock transforms the bikes feel from OEM adequate to raceday ready.
True 3Way Damping Independently adjustable compression (highspeed & lowspeed) plus rebound circuits let you finetune support through the entire 85mm of rearwheel travel. Dial in plush smallbump compliance without sacrificing midstroke firmness or endstroke control.
265mm EyetoEye Length Direct bolton replacement for stock shocksno spacers, sleeves, or frame mods required. Maintain factory geometry while dramatically increasing damping capability.
Two Spring Rates Choose 450lb for riders up to ~180lb or 550lb for heavier riders, aggressive jump lines, or cargo setups. Both siliconchromium steel springs are shotpeened and powdercoated to resist fatigue and rust.
CNCMachined Alloy Body Hardanodized 7075T6 aluminum resists heat fade on long downhills and sheds weight compared to bulky cast units. Lowfriction DU bushings keep action silky and maintenance minimal.
NitrogenCharged Piggyback Reservoir Separates oil and gas to prevent cavitation, guaranteeing consistent damping lap after lap.
FieldServiceable Rebuildable sealing system means you can refresh oil and seals for years of use, unlike throwaway OEM shocks.
More Traction: The progressive damping curve keeps the rear tire glued to loose terrain, improving acceleration and corner exit speed.
Greater BottomOut Resistance: Launch bigger jumps or drop stairsets without harsh hits to your ankles or frame.
Reduced Arm Pump: Controlled rebound prevents the pogo stick effect, letting you ride longer with less fatigue.
Confidence for Heavier Riders & Big Batteries: Carry extra battery weight or ride twoup (where legal) without wallowing or excessive sag.
Why pairing the FastaceBDA53RD rear shock with the FastaceAHX12RV inverted front fork delivers a nightandday difference.
Most riders swap a single suspension component and then wonder why the bike still feels unbalanced. Fastace designs the BDA53RD and AHX12RV as a matched set, so upgrading both ends at once gives you the benefits the factory test riders intended:
| Advantage | What You Feel on the Trail | Why the Combo Matters |
|---|---|---|
| Perfect SpringRate Balance | Neutral chassis that tracks straight under hard braking and squatfree acceleration | Rear shocks 450lb/550lb coils are valved to complement the AHX12RVs progressive dualrate springs |
| Synchronized Damping Curves | No seesaw effect; front and rear compress and rebound in harmony | Both units share Fastaces threeway circuitry (hi/lospeed compression + rebound), making clickbyclick tuning intuitive |
| Geometry Integrity | Correct ride height keeps headangle sharp for quick steering yet stable at speed | Matching 265mm shock length with the forks 200mm travel preserves OEM frame geometry |
| FrontEnd Grip Meets RearWheel Drive | Confident corner entry and explosive exits | The forks oversized 38mm stanchions fight flex while the BDA53RD keeps the tire clawing for traction |
| Longevity & Serviceability | Rebuild kits available for both components so you refresh, not replace | Same seal materials, oil weights, and nitrogen pressures streamline annual maintenance |
