Is it just me or does any elses butt hurt after about 4-6 hours in the saddle? This is my first 650r, love the bike, hate the seat. I am a sit down rider and have rode nothing but kx 500's in the past. Wondering if anyone has any info on possably softer seat foam from another bike that would maybe fit, or a source from which to get said foam? thx Wes, gardnerville nv.
