Gearing

Hi, I'm new to this forum and was looking for info on the rear sprocket on my new 900. I fill that it's geared to low and would like to lower the rpms a little at hyway speeds. Does anyone now of a front or rear sprocket change for these bikes?

Thanks, 5star

A number of people have posted results on these pulleys from Scootworks on the forum. You might want to search on Scootworks for comments on these pulleys.

I've read about the pulleys but nobody says anything about how many rpms you drop at hiway speed. 5.9% reduction in final drive sounds good but doesn't tell me a hole lot.

70 Mph

Well at 70 mph, my bike with stock gearing shows about 4100 rpm. So a 5.9 % reduction would drop 70 mph rpm to about 3850, or a 250 reduction. That reduction leaves the engin slightly about the torque peak of 3500 rpm, so passing acceleration should be basically the same.

Thanks, for the reply, It looks like you need both front and back to get the rpm's down about 4 to 5 hundred rpm's

To drop that much at 70, yeah, it looks like you need about a 11% reduction.

Hey 5star is that the Red Oak, just south of Dallas, if so Howdy I Live In Sachse, have you introduced your self or have i been in a cave again.

I am interested in your post because apparently the company that makes the pulley, is at the present, apparently having some difficulty getting the pulley made. and at present unable to ship the front and rear pulley.

Myself and others have canceled long standing orders, and are investigating other sources for the front pulley. PM if you would like more info.

My understanding of the front pulley's reduction is that it is more than sufficient to smooth the bike down at 70, and that is actual speed. The rear pulley is much more bling, and has a slightly higher reduction but twice the price. All of the post I have found seem to agree that the reduction of both the front and rear used together, would be wonderful on the highway, but have a detrimental effect on city acceleration at low speeds. Have not been able to find many post where both were used.

Search around some more, maybe other sites before you decide, but I am proceeding to get an overdrive pulley one one way or the other.
