Just bought a DR200se for transportation. Get's great mileage but kind of winding out the motor at highway speeds. Thinking about taller gearing, either a tooth more for primary or a couple less in the rear. Seems to be none available though when I searched.

Anybody changed sprockets on this DR200se? Care to share your experience?

The DR200 is not all that powerful. Raising the gearing might make it impossible to reach highway speeds.

You can check your local dealer or an accessory shop for sprockets. They have catalogs that you won't find posted on the net.

Im no engineer but a 200 cc with a top speed of 65 MPH if you changed the gearing for faster top speed you would have to be on a hill for takeoff

Thanks for the input. I was aiming to do a mild gearing change...but after some reflection, you all may be right!

The stock is 15/45 and I was thinking a tooth more in front or three less in the rear. That changes the final from 3.0 to about 2.8 or 6%. At 6k that would be less than a 400 rpm diff...hardly seems to be worth the trouble. I guess I should be content with what I got...

I wouldnt even mess with gearing, the DR200 is not made for Highway use unless your traveling at 60mph. Get something bigger.

I agree with the change may be too much for that 200. I added a tooth to the front on my old KLR 650 and went back down to stock later.

Did it affect your mileage? I used a KZ750 to commute for several years. I put a one tooth over countershaft sprocket to reduce rpms. After a couple years I went back to stock and immediately noticed how much faster the bike's passing was. The gas mileage, 45mpg average, was the same with both sprockets. So I left it stock being a speed junkie and all.

I went down 2-teeth on the rear sprocket of one of my Hawks - primarily to "move" the vibration I was getting at highway speed. It's probably like seru's, in making passing a tad less "snappy". Mileage is essentially a moot point as well.

If it takes X HP to move an object Y velocity, it takes X HP, no matter what your gearing may be.

Thanks for everyone's input. Will leave it alone. Thanks again.

ps hard to believe that this 200 gets just as good mileage as my Ruckus...and WAY faster!
