WR200 is indeed more economical
However,
It is advisable to change engine oil and spark plug more frequent
than other bikes..... abt 3,000 to 4,000 km.
Carb wash - 6 mths and air filter cleaning ard 3 mths(just take out
the filter and give it a good shake).
Fuel consumption really depends on riding style. I don't travel
above 90 km/h often and hardly rev too high. With that I can cover
255 km with 9 litres of petrol. That comes to about 28
km/litre.....economical rite....
