The AL0 Wee was the last of the old (and IMHO the best) shape. Although it looks the same as a K9 Wee, it isn't. The frame is different and from personal experience the AL0 engine bars do not fit the K9 and there may well be other differences. This seems strange that Suzuki should change the model at the end of it's production run and then introduce the Glee from 2011. I rather suspect the AL0 frame is the same as the Glee frame. Although it may, on paper, be a mish mash between the Wee and the Glee I think it was the the best looking model and then Suzuki lost the plot with the transition to Glee & Gleek . The later models may have modern electrickery but there was no reason the older shape could not be retained. The only parts that needed an upgrade were the two pot sliding caliper brakes but as far as I know they have been carried on up until now.
