I bought streak in 2009 and serviced it according to the instructions in the booklet like first 3 services in time , well at first it was a tough chick bike as handling required practice :D but after that it was a wonder bike.
If I used good premium or power fuel it gave up to 50 kmpl mileage and in normal upto 45 kmpl very fuel efficient ! even in heavy rainy days it ran like a war machine never stopped in water filled roads upto the knees !!!! very powerful bike, I always rely on it ! I bought the black version and it shines like a star ! its tail light is a beauty and fuel filling cap is very comfortable !
Just one fault after servicing, oil leaks a bit may b it will recover after maintenance !
If you are looking for looks and performance go for it !!!
