Just fitted a PC680 Oddessey battery to my 888. I also cleaned and tightened all the main cables from Battery to earth and to Starter solenoid/starter. Its now no longer a sluggish starter.
These fit the 888 battery tray (I didnt get the Metal Jacket one) with only minor mods (cut the bottom retaining lip off the tray). The new battery seemed well held by the standard top bracket but I fitted a small strap around the bottom for safety.
