I get why new riders get these 4 strokes like the Yamaha r125 but you can't beat an Aprilia rs or Cagiva mito 125 at 17 years old, Little GP bikes and really quick
Having started on an AR50 at 16, I was on the RG125 Gamma at 17, and the KR1-250 at 18… golden years! A local lad had the Aprilia AF1 50cc and another had the Cagiva Mito 125… I was jealous as hell of both of them 😂
