15T front sprocket
I replaced the front sprocket on my Ninja 250 with a 15T one from JT last night. At 65mph in 6th gear, this modification drops the rpm from 8k to 7.5k. It is not much but the reduction in vibration and noise is quite noticeable. Also the 1st gear is more useful now. I probably will want to replace the rear sprocket to further reduce the engine speed.
