Hero Honda would have never thought of having ambition for ambition but the rapid demand of heavy cc engines helped their idea, they were the pioneers in bike segment or I should say they are, they are innovative as japanese are famous for, consumer is least risk taking and so when ambition was launched last it wasnt able to get the market as passion and it got overlaped and splender took the lead, so it helped a new idea to innovate all models one by one so h/h did the same as splender+, passion+ and these two plus gave a plus to new ambition as well. It is a good bike with a well known master brand name h/h.
One should straight away buy this bike as it is the only one above 100cc and below 150cc and it is average cc bike, milege is good and look wise it is not less then a pulsar 150 dtsi which lacks in milege. My personal liking includes its reinnovated design and multiple colours and it is lone bike in 135cc segment in the complete market, I can call it as USP. Comfort is ecpected in driving and it provides that.
In simple words people having money and requirement should but it and who dont have they should look for right financer, I have nothing to say why one should not buy it, only one reason if he or she want to buy a car.
