I was sceptical of the bad reviews for the wrong parts being sent. I ordered it for my 03 yz250 and received the correct 27mm LH puller. Looks like they got their application database sorted out. Motosport; it would be helpful and reassuring if buyers can see exactly what puller is being selected for each make model.
I contacted Bikemaster directly on this and this is what they said: "At this time, we are not able to confirm the correct size flywheel puller for the 2013 and 2014 CRF450R's. We believe that it could be the same as the 09-12 but have nothing concrete to support that." - Daniel W., BikeMaster Products
