Just put one in my R90. Guide says PC 925L, but on advice of many on the web I used a PC 680 and made up some timber blocks to fill battery box as it's a smaller battery.
You will need a smart charger if you ride in frequently.
Happy so far with it.
PS: thanks _cy_ for all your hard work so far, great info & technical info on the lithiums.
