Thank you for posting this. Some people are still insisting in the propaganda that bike cannot be lowered. This should shut them up. Based on my visual estimate the shock can be lowered by an inch. The back seat will be lowered even more.
Can you measure the rear seat height from the ground at the lowest and highest setting. Post pics of bike with both settings.
Is there an english version of the manual? can you post the english instructions of lowering the bike
