Re: dan kyle forks worth it if rear is stock??
Getting the forks done is well worth it even if you are running the stock rear shock. I ran Dan's forks on the track for years before finally getting a used Ohlins for the rear. One thing that was really better with the Ohlins in the back was tire wear. Another was just that it had a nicer, smoother ride, both on the street and the track.
I would agree that probably the best bang for the buck to be just to respring the fork, and get a used Ohlins for the rear.
The going rate for a used Ohlins for a 954 on eBay would be about $500 to $600. The fork springs themselves are about $100.
