21” front tire upgrade

[Keller]

I have a Sur-Ron LbX with a 21 inch front tire on stock forks. Pre load is on max. When riding aggressively the top of tire hits the bottom of the forks.
Can anyone recommend a good front fork that would not do this? One that is more compatible with the 21 inch front tire?

I'd recommend going further down the forum to the Sur-Ron section. Lots of good info there.
