I have been riding non-gear vehicles for 7 years ( around 6000 km ).Now I wish to upgrade to bikes so that it would be easier
I would prefer a bike comparitively cheaper than many others ( as I may change bikes once in every three years )
and has good safety features, also giving mileage not less than
60 km / lit and trouble-free one.

 

get a kawi 250r ninja! 70mpg and awesome learner bike!

other than that any normal 600 is usually to big for a new person... this isn't to say a new person can't learn on it. Just means they'll learn slow and have a bigger learning curve and be less safe.

also... saftey features.... yea I'm on a bike... there isn't really any saftey features at all...

no seatbelt... no airbags... no antilock brakes.. no parachute... just you and what you wear is what makes it safe.

 

seriously? at least 60 KPL? inst that over 140 MPG?

If thats the case and Im not mistaken on my conversion. Your going to be hard pressed to find a motorcycle that will yield that kind of mileage. A small scooter might, but even then will be hard pressed to do so.

 

Yeah man, I got 141.6 mpg.

Good luck. You'll need it.
