sounds like all good stuff.
I believe that the suspension advances is not all that big from the older bikes to the new. The shocks have changed a bit, but the design is not all that major.
My Old Tracer (circa 04) has better suspension that the spider II (2013) that I had. the fox forks I feel went backwards. The open bath is much more responsive than the cartridge. Plus the adjustability is much better on the open bath. With the open bath its east to change the viscosity and the oil level to change the characteristics of the fork.........so to update the old trusty steed........if your comfy on the bike, then update it!
