Title: KX250 A4 rear sprocket dimensions
Post by: derail on August 17, 2011, 11:17:24 am

Hi Guys. I have a dilemma. I have a rear hub on a klx250 that I think is off a 1978 KX250A4 and I need a replacement 46 tooth sprocket.
 The internal diameter of the sprocket is 154mm and the PCD measurement or from one bolt hole across to the opposite bolt hole is 170mm.
 Can anyone advise the rear sprocket dimensions of a KX250a4 and if it is correct where I could purchase a sprocket. It seems to be a bit of an odd size
 Thanks, Darrell

I don't know the dimensions but i do know that when i was in the trade there was a D.I.D/JT sprockets catalouge put out by the now defunct Conco trading that had sprocket dimensions in the back,It was very handy for doing such comparisons,ask your local bike shop,they might still have a copy :)
