Great item

It´s "better part" than original for Kawasaki Versys - because behavior of these motorcycle is much better, little faster - but thanks to this it´s with the lower torque and also little quite and lower fuel consumption. The real speed now matching with the reality (what is showing the speedmeter). The original rear sprocket on the Versys is also made by Sunstar, so - this part is not alternative, but it´s original too.

Got this sprocket for my 2009 Versys

First gear on a stock versys is pretty useless. You have to shift in to second at 10-12 MPH. It is a 15F/46R stock and I bought the sun sprocket 43 tooth and now it goes up to 25mph in first gear no shifting in the middle of intersections

Steel 47 tooth sprocket

I had an aluminum sunstar sprocket that was worn out. replaced it with a steel one with longevity in mind. the aluminum sprocket is considerably lighter, but I am not so concerned with weight. no problems with fit.

Increasing Torque

I purchased a 45T and a 48T 520 steel rear sprocket for a CRF250L with a stock 40T rear sprocket. Longer chain was required, but I knew that before purchasing. Pricing was reasonable and shipment was fast.
