Stock sprockets are 14/50. It is a good all around combo. 15/50 or 14/47 will allow more function in 1st on the street and less vibration on the highway. There will not be any gain in top speed for most riding conditions because a stock TW will hardly pull redline (74mph) with the stock sprockets unless going downhill.
