These are 7-9AH (amp hour) size 4.0" X 2.2" X 3.35 LXWXH so they pretty much fit all scooters 50cc - 250cc, I suggest you bump up to a 10-14AH for over 150cc so for 250 get the larger battery.
Battery tender brand name which is De Tran is well known for excellent product when it comes to battery chargers and Batteries.
The newer Lithium Batteries are mush lighter being called Featherweight by most due they weigh about a pound compared to 10lbs for a regular scooter or motorcycle battery.
Another great advantage is quad terminals for install any direction also the Lithium batteries charge very quickly, in my shop 10-15 minutes brings them right back. Although you can not keep cranking on them when there is a hard start ir trouble shooting, if your bike is not starting right away there is another problem please address that problem and do not ruin your battery.
