i just bought a brand new duke 690.
i am very happy with the bike, i thing its the best bike i ever had.
i am just thinking if there are some kind of mods i can do to make it even faster without changing the stock exhaust.i dont want to have more noise.
i read other posts in this forum talking about air box opening , gear restrictor disconect even a wire mod on a duke .
how you did that?
can you give more information about ?
i am also thinking to change the front spocket to one teeth smaller.
anyone try it ?
sorry for my bad english,
nick
