For me its very easy to explain qualities and weak points of Discover 100 because I am using Discover 100 for last 6 years.And I would like to share some experience about Discover 100 .
Its Fuel Consumption is very maximum compare to other bikes.At the time of purchasing it has approximately 60 -65 km/litre for a next few months but after 4-5 times services or we can say that after few months it goes down 40 -45 km/litre.
Comfort-wise its pretty good because it has a long and wide seat comparison than other bikes. It has a good pair of shockers.
Reliability-wise Discover 100 not a good for long time because it has very high maintenance cost because it has many of its part containing plastic material.Its engine not good for long drive because it getting very hot comparison other bikes which is not good for any bike performance. And its Spark plug getting black powder over it after a few months.
Handling and Control wise this is pretty good because of its Digital meter and a good pair of wheels.
Look-wise I must say that it has a pretty good style. It vary some different colors according to customers choise.
In short Discover 100 not good for long time purpose but u want to purchase a bike short time period.
