How much better are the after market forks and shocks for the R3? Are they worth the $1000 - $2000 it costs? For comparison is it better then the stock OEM on say 2015 R6 or R1? I've ridden both and it's nice, much better then R3. Trying to get a feel of how much better a R3 would be with forks / shocks and if it's worth spending half the value of my bike on suspension.
