On Road Off Road says that the single Mupo cartridge option is about half the cost of the double and offers 70% of the performance.
Their price for the single cartridge was $550. This is a pretty simple drop-in installation. May be sufficient for many desiring a significant improvement at a value price.
I selected the double cartridge to get both compression and dampening adjustment. I think it was right at $1,555 installed on the bike. Remember, the left fork required modification to accept a cartridge.
As for the rear shock, Mupo has four options. They say the AB3 does not give independent rebound and compression. The AB1-EVO is arguable overkill for the street. So, that leaves the 2-way adjustable AB2 for $925, or the 3-way adjustable AB1 for $995. For $70 it's well worth the difference to get the AB1.
So, for $2,655 total installed price, I will have a transformed Hyperstrada, which because of the expert set-up for my riding and weight, will arguably surpass the performance of the one-size-fits-all SP suspension, while keeping the reasonable seat height of the Hyperstrada.
Since I tend to keep motorcycles a long time, this cost will amortize well. Probably not worth it to those who trade bikes often.
