Yes. But I barely notice the difference between my two Fazers, one with and one without Ohlins forks springs. With the Ohlins springs, I'd say it's slightly better, but it's the compression damping that's the big problem. There's not much control compared to an R1 of the same age. It feels crashy and harsh but the forks still dive like a submarine. An Ohlins rear shock makes a much bigger difference, and it does change the way you ride. Bury the front end on the brakes on the way in, turn it hard and get the weight off the front end and drive out. It's unstickable with an Ohlins rear shock. It's a very different style of riding to my other bike, a ZZR1400, on which you scythe round corners smoothly. Fazers are much more like point and shoot machines.
Fazer forks are a problem and not cheap to improve, unfortunately.
