that psyche is over.. people are now aware ... how ? because cHonda's are here and people know every brand and its qualtiy .. reputations are made for differnet brands..
moreover its yamaha and it had excellent market compared to suzuki..
it had good aftersale service and spares availability.... and you could get chinese /local/ janyan parts quite easily..
not the case for suzuki..
suzuki sales might also have increased due to easy installemetns.. (if they have increased. do you have any refrence to their recent figures ?)..
moreover its 125cc category.. thats a bit niche.. compared to 70's
