Hi, I just have bought a brand new Suzuki DRZ 400 S. I´ve found the original sprocket ratio 44 rear and 15 front is not suitable for my type of riding. Therefore I´d like to chang it with a ratio 47 rear and 14 front, but I´m not sure about the chain lenght??? I mean do I have to change a chain as well, or DRZ 400 E and DRZ 400 S they have the same chain lenght?? Please if somebody knows for sure let me know. Cheers Oliver
