Well, you have quite a good budget and thus a lot of good options as well. The first option is DSK-Hyosung GV650 also called as the Aquila 650 cruiser which costs around Rs. 5 lakh. Hyosung claims that Aquila is the strongest 650cc cruiser without any competition around.

Triumph Bonneville 790 is the second option in the league. The bike has a retro styling with circular full size headlight with chrome, small telescopic forks and big front tyre which gives it a macho look. It gets powered by an air-cooled, parallel twin 865cc engine which can produce 67 bhp and 68 Nm at 7500 rpm and 5800 rpm respectively. The engine is mated with a five-speed manual gearbox. The bike can sprint from 0-100km/hr in less than 11 seconds. It is priced at Rs. 6.20 lakhs.

Another worthy option is Kawasaki Ninja 650R which is quite popular and sought-after choice in the mid-size range. This well-rounded machine features sporty yet comfortable ergonomics.
