2017 Speedie R Front Spring

The front on my 2017 speedie R is way to soft for my weight, I weigh in at about 210-220 pounds with all my gear on and i have the preload all the way in.
With this setup i can just (only just) keep it from bottoming out.

Now i don't know what the spring rate is in the standard forks but i contacted Öhlins and they (without any explanation or asking any information) told me to get these springs www.ohlins.eu/en/products/motorcycle/08790-05--5245/

These are 10,5 N/mm but i think that sounds excessive ( I'm by no means an expert ) so i was wondering if anyone here has any experience with front springs?

 

It's not that i don't trust Öhlins, but they suggested me a spring upgrade with the only information being my weight, didn't really take into account riding style and all that jazz when i sent the mail.

So i geuss im just double checking :-D

 

You can do that? That's pretty awesome :-D
