The Bourne Ultimatum
Trail bike with non original gasolin tank I think it is a GAS GAS Delta (-1991) http://classicdepartment.com/shop/images/Gas%20Gas2www.jpg now with the extra Thumbnail i think it is a Montesa Cota 4RT (99% sure)
I have just found this link to spanish page about trial world. As Ralph says is a Montesa Cota 4RT http://todotrial.mforos.com/59927/6753631-una-montesa-de-cine/
Yamaha DT unknown, vraisemblablement DTMX 125...

Yamaha Jog 2005.
PX 125 or 200... this is one of the 500 PX 150 specialedition edition americana of 2006 ... in catalized version.... with more chrome and flashing glasses like "clearlenz" .... skated to look like the originals of the late seventies....
