14 tooth front cog for a 300 Versys
Fit as expected but does require and extra locking washer as a shim but I knew this when I ordered it.

Works to extend/expand the close gear ratio
Took some work to get them swapped (Kawasaki Vx300).Had to add some splined washers to get to the exact depth fit, but once there (2 extra foldable and 1 skinny washer) it was pretty straightforward to get it back in play.Tried a run for a few miles - checked all the nuts were tight, rode again observing different feel.It was hitting 50mph @6000rpm. Now hitting 55-56 @6000 rpm.The other notable point is the smoother tease on the friction point and take off without the jittery feeling… nice mod.

I like the rubber pads.
I'm not sure what purpose the rubber pads were intended to serve, but I think they help keep crud out of the shaft bearing.

Improper fit
This is not the correct sprocket....it ruined the output shaft on my triumph 400...do not buy

Just as described
When I need another one im getting this one I think that says it all fits perfectly on my ninja ex650.

As advertised
Works as described, using on a grey market TZR250 3XV as they have the same spline as the yz450f.
