Other than GIXXER, Pak Suzuki is not offering any sports bike / heavy bike. Inazuma, Hayabusa, etc. seem long discontinued by Pak Suzuki.
If you have a budget of ~540,000 PKR, then I would suggest to go for brand new, Zero meter Gixxer. Its even being offered on installments.
Rest, bike owners, especially the ones related to Inazuma, or other sports / heavy bikes can guide best.
