the K75s I just purchased has the original shock, I'm thinking of replacing it with a Progressive, the Progressive Suspension 465-1101 Hard Anodized Finish 01 14" High Performance Monoshock is $328.04 on Amazon. the 412-4015B is$225. will that fit. is the 465 worth $100 more? other reasonably priced options?. I weigh about 160 and am 6' , I don't need the height lower. and will be riding mostly single, unless I get lucky.
