I was surprised to find that this weighs the same or maybe a little more than the steel sprocket I usually get. I got this because I needed it to arrive quicker. It is cool looking, but I don't know what the point of the aluminum is if it's not lighter than the steel.

It'll most likely wear faster than most expensive brands but not bad for what it is...

I purchased this for my 2020 KTM 500 EXC-F even though the listing hadn't been updated to reflect it fitting the 2020 model.As shown in the pictures it fits perfect.I cant speak for the longevity of the sprocket as I just installed it but it seems like a quality piece.

I thought this was going to be a great deal if it worked out. It held up well for a while but I heard some strange noises during my last ride. I inspected the rear wheel and found the sprocket was cracking where the rivets attache the steel teeth to the aluminum center. Scary!!

Great

Great product and excellent customer service
