New rear shock for my SV650, new fork springs and emulators along with heavier weight fork oil, M4 slip on muffler, fender eliminator kit, new Michelin Pilot Powers front and rear, bar end mirrors, removed all badging and decals from the bike, and installed motoslider frame and swingarm sliders. I also have a Pit Bull rear stand for my bike.
Next mod I'll think about is to look for a good deal on a GSXR front end. It takes some doing but many people have done this swap and it does wonders for the handling and feel of the bike...then again, I may just sell this bike and buy a Ducati Monster 1100S or a Triumph Street or Speed Triple.
