Let me clear this 4valve stuff. Bajaj discover 125 st has a 4valve engine still giving mileage of 60kmpl and has top speed of 110km/hr and I ride constantly at the speed of 80 -90km/hr without any engine issue and other bikes which have 4valve engine are Honda cbr150 for 1.3lakhs and Honda cbr250 for some 2laks and Yamaha r15 150cc bike which is for 1.14 lakh and I got a 4 valve engine for 63, 000 rs thanks Bajaj (all bajaj bikes are not crap and all Honda bikes are good).
Honda is looting their customers Honda dream should be for rs50000 but they are charging as it its a 125cc bike and this bike 100t is somewhat better than 125st in speeds till 70km/hr as they have made some improvements in engine. Its a great bike a long leap for India in 100cc segment.
If you want to go for passion pro it has engine of cd100 (known as cd delux now) but is with more torque. 3 bikes passion pro, splendor and cd delux share the same engine with changes in torque level so you can imagine but this 97.2cc engine from Honda is a masterpiece let me tell you that.
Hondas another engine 110cc shared in twister (when you apply brakes the rear tyre twists hence its call twister you would have to change rear tyre or dont buy this) Honda dream yuga, dio 110cc, aviator, passion x pro share the same engine and this engine is a fail engine from Honda it drops in mileage after 1 or 2 yrs drastically.
Another competitor Suzuki Hayate awesome performance bike no bad points full value for money and a strong and sturdy engine from Suzuki which is know to have better engine than Honda in some cases you can for this eye closed the money is all yours think and spend it.
Thanks.
