TurboTouch Shocks [Fangzhong (FZ)] and NAMI OEM [KKE] Suspension (shock absorber) suit Burn-e, Klima, VSETT, Zero etc

• 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, VSETT 10, Zero 10X / Dragon Hunter 10X (T10-DDM) and Zero 11X / Dragon Hunter X11 (X11-DDM).
• For the shock to be appropriate, it needs the desired length (mm), spring force (lbs) and assemble size (internal diameter 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 on 12mm eye (inner diameter of self lubricating bearing / sleeve) which fits perfectly on the NAMI Burn-e/Blast 12mm.
  • For Nami Burn-e, a conversion from stock 165mm to 155mm Low Rider offers lower centre of gravity at expense of 45mm clearance (measured by eSN customer after fitting, see the 4 photos in product images with steel ruler). The 160mm semi-Low Rider sits between and more favourable for kick stand.
  • FZ uses a unique spanner to adjust the pre-load making adjustment easier, however you can also use traditional C Spanner Wrench . One spanner is provided for each two shocks ordered.
• Both KKE and FZ shocks have a native 14mm internal diameter with 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 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. Front and rear are identical length (stock being 165mm) on Burn-e.
• Domestic orders are sent road freight as they are "restricted items" with Australia Post, choose regular post at checkout. International orders typically sent via FedEx, at check select Australia Post International Courier shipping service. The KKE shocks have pressurised air, FZ shocks contain a small amount of Nitrogen, therefore we need send international via FedEx.

4. 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.
   
   
5. KKE shocks adopts a "S / F" marking on the red knob (this denotes slow / fast dampening, not soft / firm). Some older KKE shocks were observed with a non-round knob, with reverse orientation which was counter-intuitive. FZ adopt a R +/- marking on the knob, indicating rebound dampening strength, the +/- is more intuitive and less likely to mistake. It is recommended not to set the damper to either full extent of extreme firm or soft on most shocks (i.e. due not ride with the knob set to the full extent in either direction, have it backed off half a turn / 4 clicks).
6. Michael J Breen provides excellent advice on how to adjust rebound/dampening strength and pre-load strength.
7. 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.
8. 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.
9. 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.
10. 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.

13. Some general guidance on weight from Rydology:
    
14. Image below shows the FZ shocks fitted to rear of Burn-e. Note the observation of silver washers in application (Courtesy Tobias Olsen at NAMI Electric Scooters Worldwide Group). As the loading distance (width) on KKE shocks is 15mm, whereas FZ adopts 14mm, a gap of around 1mm will be present if renewing KKE shock with FZ. The image shows placement of two 0.5mm silver washers adjacent to suspension bushing to improve the lateral spacing along the shaft. There is typically around 1.4mm of space to pack, with each build having slight variance. Use appropriate width washers to pack any unnecessary gaps/space. It needs not be precise, just enough to keep the shock positioned centre.
    
    
15. Note on travel for Mantis King GT: The somewhat proprietary 9.0mm (Rear) / 9.3mm (Front) travel on the Mantis King GT Shock can be worked around by adding a PVC/Poly/Nylon spacer/bush to the existing "bump stop" on the vertical shaft (12mm diameter) for shocks that have the more common 10mm travel. This ensures appropriate clearance of the tyre against fenders. Add comment at checkout if you require some spacer components for this purpose (a selection of 0.3/0.5/1.0mm spacers will be included). Further discussion in Sim's post in Kaabo Mantis King GT Facebook Community.
16. eSN recommends periodic renewal of the SF-1 self-lubricating bearing 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 12(a)x14(C)x16(d) on FZ.
    
    
17. For NAMI Burn-e and Blast models, there are three suspension shaft spare part items. It is recommended to renew these shafts when renewing shocks.
    1. For Top, Front, 50mm
    2. For Top, Rear, 80mm
    3. For Bottom, 120mm
       
       Additionally, there is Suspension Bushing on both sides of the suspension.
