Thought i would Share a Value that I found today while shopping for a replacement sprocket for my 09 450 xcr-w.. I run a 52T rear and found that BPI Sprockets has KTM 52t Sprockets that they refer to as "Overruns" for $20 Bucks!! I called BPI , Clackamas Oregon, and talked with guy there. He said they have 52t Anodized sprockets that came off the line that were stamped 50t. that is the only issue. Part # 5254 Bottom line: $27.50 delivered to my door a great BPI 52t Anodized orange Sprocket http://shop.pbisprockets.com/product.sc?productId=451 Hope one of you can take advantage of this also.
