1.cbr is 1 silinder

2.ninja250 n z250 sama 2 silinder parrallel bezanya ninja more like superbike becoz got fairing and for me not worth getting ninja brand new as its super xpensive and god know how long u will use it before u r tempted to upged ur lesen n bike(its 25k non SE one u can get 2nd hand 2011 ER6 for that price)

3.megeli is not proven reliability bike yet so its cheap and if u ask me not worth risking it

4.blade 250 2 silinder L or V twin(dun remember which) more powerful than 2 silinder paralel but usually got issues becoz its korean made hyosung but its cheap n worth it as the issues now has reduced greatly and even with issues its not as bad as u cannot use the bike
