Word of advice to anyone considering aliexpress etc that I learned hard way .. trying to buy cheap parts from China will set you in long term same / more as quality well engineered brand name ... that goes for rearsets, steering dampers etc ... Sure, there are some situations where some of those chinese parts makes sense, part lasts - is well designed, but that is rarity in my experience.
In case of "Arashi" ,,, the shift leveler / peg when mounted was almost same height as the highest footpeg position, brake had unsolvable issue also ... making shifting impossible. Just badly designed part, not even considering robustness etc.
Many online reviews have same experience on other bike brands. Spend hundred or so more, save yourself the aggravation and get for example Italian Spider rearsets ... for around $300 if cash is short.
