The Ohlins has been installed and set up. They did have to fashion a custom bracket to accommodate the remove preload adjuster, but all in all it's a very clean install.
Everyone I talked to there said I would notice an immediate and significant difference in the way the bike handles.
No lie. I don't think I would have believed that a rear shock and spring swap would make such a big difference. Even at the lowest preload setting, the Ohlins is significantly stiffer than the Progressive. The bike seems to ride at, what I perceive to be, it's stock height. I had always thought the Progressive caused the rear of the bike to ride too low throwing the geometry of the bike off.
With the Ohlins the geometry "feels" right to me. The tech said that improving the rear suspension can have a significant effect on the front end, counterintuitively.
In many ways it feels like a different bike. It leans differently. On a few corners I surprised myself because the bike cut into the corner sharper than I'm used to. I don't know jack about suspensions, but it feels like the rear end is coming around faster, if such a thing is possible.
The ride is stiffer but not uncomfortable and over hard bumps the shock seems to give more than the Progressive.
I talked to the tech about the front end. He took it for a test ride and said it felt right to him.
I still say something is not right with the front end. It may even just be the tire. These bikes are crazy sensitive to tire wear and pressure.
