TurboTouch FZ Coil & Oil Adjustable Shock Absorbers [Fangzhong | KKE (NAMI OEM)]

• Shock absorbers / suspension featuring NAMI stock KKE and FZ (Fangzhong).
• The range accommodates most of the popular makes/models of eScooters such as NAMI Burn-e and Klima, Kaabo Wolf King GTR & Mantis King GT, Teverun Fighter, KuKirin G2 Master, VSETT 10, Zero 10X / Dragon Hunter 10X (T10-DDM) and Zero 11X / Dragon Hunter X11 (X11-DDM) etc
• eSN stocks the world's largest collection of off-the-shelf eScooter shocks. For the shock to be appropriate, it needs the desired length (mm), spring force (lbs) and assemble size (internal diameter for shafts and width). Refer to the application guide to help choose appropriate type.
• Choice of:
  • Genuine NAMI Factory Spare which is the NAMI factory original manufactured by KKE, 165mm, 1800 lbs, 12x15 assemble.
  • Aftermarket Fangzhong FZ Series (TurboTouch by eScootNow):
  • FZ is considered a superior shock than the KKE amongst the NAMI rider community. You can check rider experiences and reviews of the Fangzhong on NAMI Burn-e here, here and here. FZ performs very well as an uplift from the stock KKE and are considered superior to other well known brand of EXA.
  • FZ adopts oil dampening with a small amount of nitrogen, whereas it is understood the stock NAMI KKE shock uses air rather than nitrogen (and may not be an oil shock). Regardless of the composition, FZ are recommended over KKE.
  • FZ has a more precise bushing for 12mm shaft (inner diameter of SF-1 self lubricating bearing / sleeve) which fits perfectly on the NAMI Burn-e/Blast 12mm.
  • For NAMI Burn-e, a conversion from stock 165mm length to Low Rider 160-150mm with the later offering lower centre of gravity at expense of 45mm clearance (on 155mm measured by eSN customer after fitting, see the 4 photos in product images with steel ruler). The 160mm semi-Low Rider is favourable with the Blast Kick Stand which is shorter than Burn-e.
  • FZ occasionally supplies a spanner / wrench tool for the preload nut. Up until late 2025 a unique shaped relatively soft silver tool which is not practical with the force of the spring on the thread. A more traditional but lightweight version of TurboTool C Spanner Wrench was included early 2026, late 2026 are without any tool. If you need a decent tool, order the TurboTool C Spanner Wrench.
• Both KKE and FZ shocks have a native 14mm internal diameter with SF-1 self-lubricating bearing (brass coloured bushing/sleeve) which results in a 12mm sleeved internal diameter for the shaft (suitable for NAMI Burn-e and Blast 12mm shaft). The 8x24mm assemble has in addition a silver coloured hardened steel bushing/sleeve that further reduces the 12mm diameter to 8mm, for the 8mm shafts of NAMI Klima, Zero and VSETT.

• Typically required when replacement is needed for performance uplift, renewal (including premature failure) & physical damage. Relatively easy to fit (does not require significant tear down).
• Qty reflects one shock (i.e. one wheel). Order quantity 2 for both front and rear.
• Checkout will apply road freight shipping for domestic orders (within Australia). International destinations have option for UPS/FedEx. FZ shocks contain a small amount of Nitrogen, therefore cannot be sent via air services domestically or International (Air) Post, hence we send international via UPS/FedEx.

Older version of application guide:

• Optional: TurboTight 6pcs Spacer Washer Pack Kit - 8.4mm for one shock (two 12mm shafts):
  • This kit, part of the eSN TurboTight range contains 16 pieces of assorted nylon washers to ensure there is sufficient bushing on 12mm suspension shafts. The washers help centralise positioning of the shock to keep it perpendicular to the suspension shafts by reducing any unnecessary gap/space on the shaft bushing.
  • The gap need only be large enough to allow free movement, noting:
    • Typically most makes/models (stock builds) have excessive gaps on a shaft bushing in the order of 0.5 - 1.75mm. In almost every instance, there is room for improvement to reduce that gap.
    • FZ shocks have "narrow" 14mm loading distance. Most eScooter shocks including KKE (NAMI stock) are 15mm. Therefore, an extra 1mm gap on shaft when uplifting from KKE to FZ in addition to any stock gaps (0.5mm+).
      
      There are two shafts per shock (top and bottom), therefore combined upper and lower spacing (such as that observed on Burn-e) is up to 6mm per shock (3mm per shaft, typically 1.5mm each side).
      
      The combined thickness of kit accommodates 8.4mm across the 16 washers, allowing 4.2mm packing per shaft - sufficient for most installations.

• The optional kit includes:
  • 4 x 1.0mm Nylon Black (17 or 20mm OD, typically 20mm),
  • 4 x 0.5mm Nylon Black (17 or 20mm OD, typically 20mm),
  • 8 x 0.3mm Nylon White (18mm OD).
    
    
    
    Washers are typically fitted between the shock and the stock bushing (such as bushing on NAMI, or equivalent). Image shows two 0.5mm silver pack washers (rear of Burn-e) courtesy Tobias Olsen post at NAMI Electric Scooters Worldwide Group.

4. NAMI Burn-e Kick Stand length considerations:
   
5. Fangzhong rebound setting guidance courtesy Zsolt Szűcs: 165mm 2000lbs: "I use it for 3000 kms without any serious problem and so much better than the KKE. Just have to watch out the right rebound setting. Too high(slow) will cause oil leakage. I use with 4-5 clicks from the slowest. As I tested 3 clicks from the slowest with 90+ kgs can cause the leakage. Below 100 kgs 4-5 is good, above 5-6 is OK. Below 5 Celsius I add +1 click so 5-6 clicks". Similar confirmation in Blade Scooter Owners Group, contributions by Bogdan Hawk including this post shown below.
   
   
6. KKE shocks adopt an "+ / -" marking on the red knob (this denotes dampening strength: slow - fast (not soft / firm). FZ adopt a R +/- marking on the knob, indicating dampening strength (rebound). The +/- is more intuitive as it informs strength, that is + increases the dampening strength. It is recommended not to set the knob to full extent of either extreme firm or soft on most shocks (i.e. best to back it off a few clicks). 2026 models are planned to be fabricated with an eSN branded knob where:
   R 💪 in middle,
   - Slow on clockwise,
   + Fast on counter-clockwise.
   Images show KKE (left) vs FZ (right)
   As you turn clockwise on the KKE the damping strength is stronger (slow). Clockwise is less damping strength.
   As you turn clockwise on the FZ the damping strength is weaker (fast). Clockwise is more damping strength.
7. eSN guidance on how to adjust shock preload and dampening strength:
   
   The appropriate spring strength (lbs) is not purely relative to rider weight. Riding style has equal influence on desired spring rating. Generally a heavy rider, seeking high-speed stability is better equipped with 2500lbs springs rather than 1800-2000lbs.
   
   Preload changes where the suspension starts its travel cycle. Adjusting preload lets you dial in the correct "sag" - the amount the suspension compresses under the static weight of the eScooter and rider. Applying more preload (tighter) will reduce chassis ground clearance as the spring is being compressed and there will be less sag when rider steps on deck. Getting preload right keeps the shock in the middle sweet spot of its travel so it doesn't bottom out over heavy bumps or top out when extending. To set initially, observe the chassis sag 20-30mm when you step on the deck. Anything much more than that will likely not be stable at high speed (sloppy) and risks bottoming out - more preload is required (tighten the nut). If sag is insufficient, reduce pre-load (loosen the nut) so as to prevent top-out.
   
   The strength of the damper inside the shock can be initially set so that the dampening strength strength is just enough so that when you drop the scooter from a 300 millimeter distance the wheel should not bounce excessively. This will also test the health of the dampener inside the shock.
   
   When doing road testing, finalise your preload strength firstly, then progress to damper. It is best to take notes of the adjustments so that you have a record of changes, and make only one adjustment at a time. For example, too much preload on the front will make the rear very sloppy, which rear damper will not address, then when you reduce preload on the front you may find you need more preload on the rear.
   
   Electric Scooter Guide has a reasonable Set Up + Settings video (note length of thread varies between KKE and FZ).
8. Michael J Breen's more on suspension (Burn-e) post suggests the stock KKE 165mm shocks have travel of 20mm to the rubber bump stop plus about 5mm when the rubber compresses. The 160mm FZ shocks have 30mm travel which is more generous without any known clearance issues. He also observed 5.2:1 lever ratio.
9. It is understood the KKE Shocks (such as those stock on NAMI makes) from mid-2023 have higher likelihood of premature failure as production changed to provide stronger dampening, which approaches limits of the shock's design capability when used with springs of high spring force. It is observed the post mid-2023 shocks prematurely fail much more often than the pre-2023 production units. Ref: Michael J Breen's post in NAMI Electric BURN-E/BLAST/KLIMA/ Electric scooter.
10. Zsolt Szűcs demonstrates a failed KKE shock that no longer responds to damper adjustment of slow and fast. This is a good test to determine if shock is performing. He observed the failed shock resulted in more bouncing and there were a lot more shaking sounds when working because of the less damping.
11. Remember to apply a PTFE spray flush to all components and clean off any excessive residue. It is recommended to run "dry", that is do not use petroleum products (grease, oil or similar) as these products attract dirt and debris which will result in premature wear, failure and "squeak" noise. Don't forget to use thread locker when you have everything bedded in.

15. Some general guidance on weight from Rydology. Weight includes that of the eScooter. These values are for those wanting generous travel (a "plush" ride) in typical urban environments. Consider adding a further 500lbs where high speed stability is required.
    
16. Note the Kaabo Wolf King GTR adopts a different assemble top and bottom. The upper shaft is 8mm diameter, lower is 14mm. The lower shaft of 14mm diameter does not allow for self-lubricating bearing with the KKE factory original shocks, hence there is stress on the shock casting causing premature failure. As an aftermarket replacement, the eSN TurboTouch FZ (currently in production phase expected November 2025) is expected to resolve this structural limitation by introducing self-lubricating bearing into the assemble while retaining the somewhat uncommon 14mm shaft support. It is anticipated the design will also reduce stress on where the shaft meets swing arm, you will note these prematurely wear under the stock design. Further details including tear down video in comments on this eScootNow page post as previewed below.
    
    There are also a couple of posts such as this on eScootNow Facebook Group and this other one. Images below from those posts reveal the shearing of the shock adjacent to that 14mm assemble. There is only a hard steel sleeve/bushing - there is no self-lubricating bearing.
    
    
17. Note for Mantis King GT: 9.0mm (Rear) / 9.3mm (Front) relates to the spring wire diameter, therefore the front spring slightly heavier than the rear, as is the norm for the ~1500lbs strength springs in eScooters (stronger up front for stability). Further discussion in Sim's post in Kaabo Mantis King GT Facebook Community. Factory original (KKE) has designation as shown:
    
18. Kaabo Wolf Warrior X Max (which features a rear shock, 03.MK.500/502) is 125mm length, 9.3mm wire thickness, in assemble of 12x14/15 top, 8x24 bottom. It differs from the stock Mantis King GT 9.3mm front shock (03.MK.500/502) in that stock Wolf Warrior X Max is non-adjustable (no red knob) and has no 8x24 bushing in the top. eSN does not stock a shock variant in that assemble, so your two options are:
    1. 125/1500/08x24 press out top 08x24 to reveal 12x14/15 (recommended as renews lower 8x24 bushing).
    2. 125/1500/12x14 re-use (re-insert - press in) existing 08x24 lower bushing if in suitable condition.
       
       Ensure sufficient spacer/pack washers on both 8mm and 12mm shafts are fitted as required as placement is critical with short shocks - keep the shock postioned square without any stress from friction.
       Photo's below show the original shock, which the factory supplies trade at USD$16.70.
       
       
19. eSN recommends periodic renewal of the SF-1 self-lubricating bearingbearing in shocks as part of heavy maintenance, or when convenient. The bearing is a brass coloured bushing that acts as a "sleeve" that sits inside the eye of the shocks at top and bottom. If the bearing deforms, even to less than 0.1mm, the suspension will develop play and result in a "knocking sound" when weight is lifted off the wheel, such as riding through corrugations. Often brand new NAMI KKE shocks will present excessive play, resorting to filling the gap in the bearing with alloy film as demonstrated in this gap fix video. In eSN's experience, renewal the bearing (bushing/sleeve) is the best resolution - tap it out and tap in another. The FZ shocks are provided from factory with a mint bearing for the precise 12mm internal diameter of NAMI shafts. The self-lubricating bearing is 12(a)x14(C)x15(d) on KKE and slightly narrower 12(a)x14(C)x14(d) on FZ.
20. For NAMI Burn-e and Blast models, there are three suspension shaft spare part items and bushing. It is recommended to inspect and if necessary renew these shafts when renewing shocks.
    1. For Top, Front, 50mm
    2. For Top, Rear, 80mm
    3. For Bottom, 120mm
    4. Suspension Bushing on both sides of the suspension.
       
21. Special consideration for KuKirin G2 Master (& other ODM's such as Mercane and Veloz): these models adopts relatively unique 10mm shafts requiring shocks to have a 10x32 assemble. The 10mm shaft size is problematic as the external diameter of the appropriate bushing is 14mm, which is the native size of the hole in the casting in the shock. This creates similar challenges of the Kaabo Wolf King GTR lower shaft whereby there is absence of 12x14 self lubricating bearing and associated benefits the bearing delivers. Often riders will retrofit the original, stock 10x14x32 bushing (ID, OD, length) into an aftermarket shock to convert an aftermarket shock to be of suitable assemble. This requires removal of the aftermarket shock's 12x14 self-lubricating bearing and 8x12 hardened steel bushing (if present) so that the original 10x14x32 can be fitted. The conversion, if pressed in professional manner, with a bushing that will produce results as good as one can attain, given absence of self-lubricating bearing.
    
    The TurboTouch 10x32 shock for G2 Master incorporates the FZ factory-pressed hardened steel bushing to accommodate 10mm shafts in the original G2 32mm length allowing a "straight swap out". When fitted with a shafts that are in good condition, this produces a high precision, tight fit, in part due to the quality of the factory-fitted 10x14x32 bushing. Typically 3rd party bushings in this size are manufactured from stainless steel, which is not ideal due to being soft resulting in deformation a tight fit over long-term use. Likewise, fitting a 10x12x32 "sleeve" as a bush with the SF-1 12mm self lubricating bearing isn't ideal due to being thin (and typically not hardened steel).
    
    Images below show the TurboTouch FZ with 10*32 assemble. The last image shows assessment measures against a FIBRO Hardened Steel (60 HRC ) 10mm shaft to ISO 8735 but with m5 tolerance (tight interference fit) (60 HFC).
