my say it has to be a GS150R...........
its the most refined engine i ever rode........
its uber smooth.....
gives mileage around 58-60kmpl....
looks like a beast
....check it out in reality
even though its the heaviest among 150cc seg it gives top speed of 127kmph(verified by me and Mach50) without mods....
no vibrations even at 120kmph+ speeds
is rock stable at such high speeds.......
is a perfect bike for touring......(its 2 G2G old)
can do cornering well.......
one of the best looking consoles.....
can smoke out with the likes of R15,karizma,zmr,pulsar220.....(forget about other 150cc bikes........they are nowhere in picture.........as experrienced from my latest lavasa G2G....)
gives you a feel of riding something big......
its heavy still you can stunt with this one.....Mach50 has posted a video in GS ownership section......
three modes to drive according to your necessaties.......
if you want mileage the ECO mode
if you want power like that of karizma's then POWER mode
if you want both then GOD mode(that's what people call it)
and you can easily rely on this one for 10 years!!!
drawbacks........
since its heavy it will take time for you to handle it........otherwise it glides its way out......
and the only problem which i face is the headlamp....its adequate for city riding but not for highway.........(fix a HID and this is solved.....)
All the best for your bike.............and Ride Safe!
