Fisheye equivalent lens focal distance.Can you elaborate on that? I've never seen anything like it. What is that big canister for?
About those shocks:

A 330 mm o.c. eye-to-eye measurement will give you the same shock length as a OEM Yamaha VMax rear shock. These rfy shocks probably have a very-light set of springs, not something set-up for a 600 lbs VMax, before sticking a rider on there. At the very-least, you'd need to get the springs in the proper range, before worrying about the damping. Choose the wrong length (too-short) and stick with the 'scooter' spring rates they're apparently set-up for, and you could end-up with a near rigid rear-end, a 'hardtail.' Not something I'd want for a bike I'm riding through potholes, and broken uneven pavement.
Perhaps a dragstrip-only bike can put-up with struts, but my spine cartilage vertebral discs need some suspension. "Get-up on yer footpegs" cries should have ended with the 1958 Duo-Glide.
I've seen a guy on youtube who rebuilds the rfy shocks to work-better, he's been written-up in some internet sites about inexpensive alternatives for expensive better-quality shocks.
