15/41 For flatlanders only, although you can always kick it down into fifth if you have to.

Here are some gear configurations and their respective final drive ratios:

'''Information & opinions on some low-geared combinations'''

*15/42: This works fine in twisties and on a track, although I do prefer 15/45 for that kind of riding. 15/42 can handle performance riding, too. You just have to keep the revs up.

:I'd imagine 15/41 is almost the same, but to me, 15/42 is enough. I wouldn't go any lower on the back.

*15/41: The 15-41 results roughly in 1000 RPM per 10 MPH in 6th. The engine is doing about 5750 RPM at an indicated 60 MPH and spinning at about 6900 RPM at an indicated 70 MPH. You can check the [[Speed @ rpm calculator|speed calculator]] for more information on speed, rpm's, and gearing.

:The 250 engine has plenty of power, but is a small “peaky” engine that has a narrow power band compared to a big V-twin or an automobile engine. You just may need to spend a little more time in 5th than a stock bike if you live in hilly country or are battling a stiff head wind at highway speeds. Passing can be done comfortably in 4th or 5th. I would look at the 6th gear as an "overdrive".

:When riding single I only felt the need to leave 6th if I was on a steep incline and traveling at less than 50 MPH. When taking one of my offspring for a ride 5th is sometimes needed to maintain highway speeds if heading into a stiff headwind or going up an incline. In 4th the bike will accelerate smartly up steep inclines. Just keep in mind that close ratio transmissions are meant to be shifted.
