Hello and thanks for your question.
Due to the lack of suspension adjustment, we offer for the front, the 20IDS fully adjustable cartridge kits, which replaces the complete internals of the front fork and then allows compression and rebound damping adjustment plus spring preload adjustment.
For the rear we have 4 options from our Razor-R shock absorbers:
Razor-R Lite, this shock has rebound damping adjustment, manual spring preload and ride height (shock length) adjustment.
Razor-R Lite HPA. same as above but with hydraulic preload adjustment.
Razor-R, this shock is fully adjustable compression and rebound damping, shock length and manual spring preload.
Razor-R HPA, as the Razor-R but with hydraulic preload adjustment.
All 4 options then are available for specific rider weights. 65-80Kg 80-95Kg 95-110Kg & 110-125Kg
We have a dedicated distributor in the USA called Orient Express who will be more than happy to help.
