Which part of it do you need? If it's the same part off of the 696(which I think it might be), I just bought the entire throttle control area. I have the grip, plastic roller, and piece the throttle cable mounts to. Let me know. Also, if it's just the cover you need, you can get it for $5 from
www.commoto.com Just flick through their OEM parts guide; I think it's on page 68.
