Back to the sprockets, I just installed a 44tooth rear on the xp200 along with the 16tooth i had already put on up front its a whole different bike. Top gear is so relaxed now and doesn't show any signs of being to tall for the little engine to pull. I weigh around 210 and it pulled me up a decent incline in 5th. With the front up one and the rear down four its like its got a 6th gear that it desperately needed. 1st gear is still low enough that you dont have to slip the clutch too much. Its still lower than my stock DR650. I cant wait to see the gas mileage numbers. I was getting nearly 100mpg before when i was taking it easy so im thinking i could break the triple digits barrier now.
