New ZX25-R as a beginner track bike?

I'm saving up and planning to get into trackdays next year, but I'm hoping to race in the future, so I want to do it right. Many people recommend starting on smaller displacement bikes such as the R3 or rc390 for, as I understand it, 3 main reasons: cost to run them, simplicity of maintenance and because they force you to get better as a rider and build a strong foundation.Given that the common recommendations are 2 cylinder, curious if the small inline 4 is a good option for starting on? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/dv1m63/new_zx25r_as_a_beginner_track_bike/?utm_source=ifttt
