Fitted Gazi Rear shocks

Well my bike came with progressives and they've been bottoming out riding 2up lately. I'll see about adjusting them but wondered what other options to consider. I'm not real impressed with the air shocks I put on the hardly two years ago
 
Shocks are actually designed and intended to have the pre-load adjusted when carrying differing loads like a pillion and adjusting them is far easier than swapping them over for something else that would also have to have the pre-load adjusted for the load you are carrying whether it is just you, you and lots of luggage or you and a pillion - just sayin.

Which model Progressive do you have?
 
440-4002C
I just found the box with instructions inside. Looks pretty simple

If you have the 13" eye to eye version it should improve the front end steering response. Very easy to adjust without tools like the 444 version which is the latest update http://www.progressivesuspension.com/product/1423/444-series-shocks
If you and the missus are getting heavier (or just have more luggage ) you can get the HD version or just replacement HD springs. I think Progressive will even rebuild yours for much less than replacement cost if they are getting a little long in the tooth but that should be at least 30,000 miles of hard use.

2 cents more.

If you like to ride fast on the highway, the 13 inch rear shock has more twitchy handling at high speed.
I had my 13" YSS shocks shortened to 12.5 inches and it solved the unnerving wigglies during quick lane changes at 100+ mph.
