Motorcycle factory tours?

My husband is a motorcycle enthusiast---is it possible to tour any of the motorcycle factories in Japan? Any info is much appreciated.

I only found Honda's factory tour.

Honda,Hamamatsu factory in Shizuoka.
9:30-11:00 13:30-16:00
From Monday to Friday tel 053-499-2111
You have to make a resevation 2month (at least one week) before you visit.

I think Yamaha,Kawasaki has factory tours.
Why don't you check their homepage and e-mail them in english if you can't speak japanese.They will do something to you.

I'd also love to do a tour of a motorbike (or even a car) factory in Japan. If anyone has any links or tips I'd be very grateful. Thanks
