Thread: Starter bike for 10 & 14yo

Looking to get a bike to start the boys on. The issue is the age and size gap, ideally I'd like one bike to start with, but it will probably be to the detriment of one of them. Either too small or, too big. 10yo is 4ft 5, 14yo is 5ft 3

Other thing I'm undecided on Is bike choice, low maintenance low performance 4 strokes such as the Drz 125 or more performance orientated ktm85, crf150 etc.
