I originally made some plates about 2 years ago to install a R1 rear shock, which transformed the ride of the bike. Doing it that way created some other problems that I excepted because I didn’t want to cut my battery tray. Well after riding my dorsoduro for a while and switching between them I could no longer deal with the issues. One was by raising the rear approximately 15 mm it made it turn quicker, which probably wouldn’t have been too much of a difference but with a 55 series rear tire and bigger rear sprocket, which shortens the wheelbase it was kinda twitchy. Another problem is the piggyback on the shock would hit the swing arm if I had the rear too soft, which I loved the ride. I trimmed my battery tray, made a small plate from some thin aluminum which you can buy at a home improvement store to fill the bottom of the tray and had to buy a small battery $30 on amazon. All the problems I had before are gone, I should have did it this way to begin with. I could have went all out and bent and cut everything at work but I wanted to see if it could be done with simple tools most guys have laying around. Dremel, 4” grinder and basic hand tools, took me about 3 hrs to do. I actually took some pictures if anyone is interested in giving it a go, I know a few have a shock laying around.
