Two questions: 1) What are your recommendations for an aftermarket swingarm for the 01 Raptor for motocross? 2)Does anyone know where to get aftermarket seat foam for the Raptor. The stock foam is thin and soft, and the cover tears rather easily. Hi-Flite now makes a desert seat for the Raptor but they said it will be 5 inches higher than stock, which sounds like too high. Has anyone tried Hi-Flite stock size foam, is it superior to Yamaha stock?
