Hi, I'm currently 16 and I have had SR 70 as my first starter bike and I also have had a ride on 125 which was also pretty easy to learn over all I'm very good at both but lately I've been thinking of upgrading to 150 maybe 200, so I wanted some advices if it would be a good idea and if so, which bikes are good in quality and like in affordable range,my budget is 300-400k, also must be 4 stroke
Please suggest some good ones
