Koni 2615 Rear Shock
When I started this project, I had an Ohlins shock mounted on the Bike, with remote reservoir mounted on the right under-seat rear subframe tube and remote preload adjuster strapped under the seat on the left subframe tube. However, I found that I could not mount the rear luggage rack with the Ohlins in place, since the remote reservoir was occupying the space that the rack needed for its mounting brackets. Rather than deal with re-plumbing the hoses on the Ohlins, I sold it and bought the Koni.
The 2615 is an fairly ugly steel-bodied shock which gives up a lot of aesthetics to make a price point. The four position dampening adjuster is linked, i.e. it adjusts rebound and compression dampening settings simultaneously. It does *not* come with a preload spanner, nor is it rebuildable. The nitrogen gas is contained within the shock body as opposed to inside a remote reservoir, which some folks don't like.
Given all of that, I like it. It uses the ubiquitous washer-stack dampening system, and the high/med/low speed washer stacks seem to have been chosen with good all-around settings. As well, the linked dampening settings seem well matched for *most* circumstances; there have only been a few occasions when I wished for independent dampening settings. It's stiffly sprung as built, so I have not missed the preload spanner yet. The lack of rebuildability was not a major issue for me, since the 2615 (like most Koni products) has a lifetime warranty - I expect that when it gets a bit tired, I'll just turn it around and ask for a warranty exchange....
