Before we continue: its just my opoinion. Just because you find your bike here doesnt mean its necessary that its bad. Some qualities appealed to you / certain others dont appeal to me. All in the game.
Ranked from worst to less bad
1) Yamaha RXG
If Yamaha lost its Indian market, it is solely owing to the efforts of this machine. Single-handedly made sure that the YamRX brandname would not live to the next generation. Whatever Yamaha did after that, it fell further. Hope things become better.
2) Hero Honda Achiever
This did to Hero Honda what RXG did to Yamaha. Hero Honda sales of 2005 were worst-hit. "None sink lower" would have been a better statement. Hero Honda flopped big-time with the triple release: Super Splendor / Glamour / Achiever. Achiever was the worst.
3) TVS Centra
FLOP
4) Honda Unicorn - latest
Whatever others say - I dont like its looks. The earlier one was pretty decent.
5) Bajaj Byk
FLOP, just like Centra, but a bit better since Centra looks bulky, this atleast isnt.
Lots of others are there too, but these are the worst.
