I loved the looks of this sprocket for my 2018 Honda CRF 450R 10 paddle dune bike. This sprocket was installed on a new bike with new drivetrain and lasted 19.5 hours in harsh dune environment. It probably would last longer in a non dune environment. I have never had a sprocket wear out this quickly even at dunes. For my new sprocket, I went with Moose Racing aluminum center and steel teeth as steel seems to hold up better. As a side note, bike was detailed out after every ride with drivetrain being cleaned and lubricated every time and adjusted when necessary. Please see old worn sprocket held up to new sprocket for teeth comparison, note "shark tooth" appearance of bending teeth.

This sprocket started to shows major wear signs after about 5-10 of use. From my past experience, it should last much much longer than that.
