[1] Later Suzuki models feature slightly different body panels which will not fit directly on earlier models.
Although the target audience for the motorcycle is the youth and small adult market, it is also available in "L" version which feature larger front and back wheels and sprockets.
This version is designed to accommodate larger adult riders.
The "L" version is also equipped with hydraulic disc brakes in the front.
