OEMdirtbikeparts started by parting out a kx450 in 07 after a bad crash in the sand dunes by overjumping the landing and snapping the rear swingarm off. Soon after, we started breaking down new dealer bikes and buying race team factory parts. Now, after 500,000+ sales, we've learned a lot from our customers on which OEM items were in need of improvement and better upgrade options from what's already produced, so this is what we like to sell, the top shelf works, and some say unobtainium items that can handle the abuse of the best riders which is who we've sold to the last 15 years from champion SX teams Freestyle gold medalist! Thx for the opportunity to connect!
