Very interresting indeed.
I've sent a mail to know if a special tool is needed to compress the spring.

IF you need to compress the spring most of those tools you see for sale are not strong enough to compress the spring. Those tools you see are made for springs on dual shock bikes. I know cause I've tried using them on other monoshock motorcycles of mine and they will bend and twist. They may not even allow you to finish the installation as they may break during spring removal. I've also tried the tie down method of compressing the spring. Kinda dangerous. IMO, the best, safest, and easiest way is to remove the shock and take it to the motorcycle shop and have the service dept change the spring. They shouldn't charge much to do this. I think I paid 20 bucks.... Just a heads up.
 
This is the answer I got from Hornig:

" Thank you very much for the e-mail.
We recommend to get this work done by a qualified motorbike mechanic. You need special tools to compress the spring and you have to underpin the rear of the motorbike to keep it from collapsing when removing the shock absorber."

Ratchet straps work just fine. Checkout YouTube for relevant instructions.
