There are two options.
An Ohlins Complete fork the FGRT811, and the Ohlins 30 MM Cart kit.
For the Street the Ohlins fork is the better way to go. For the track, I am not sure which is better yet.
They are both very very good.
But based on your using the bike for the street as well as the track I would recommend the Complete fork.
We have the forks at $, plus shipping, this includes springing for your weight and resetting the oil level to our spec.
We have the 30 MM cart kit for $, this includes springs, but does not include shipping.
I have both in stock.
Thanks, Dan
