anyone knows about that http://www.nomadtanks.com/ check No 6, already installed on a TE510 09 with success and with a Touratech spare part, used on BMW GX650 to connect the std tank with the Rally one, i have an extra 4.5 litres along with the IMS oversized giving me now with at least 170 klm of capacity in Rally Raid conditions,
i used the extra rear sub frame, the one Husqy uses for taillights. The tank is bolt on the rear fender, two holes and some reinforcement in under the fender, also two straps and there it goes, 10 min installation for the rear tank and 20 min connection of tanks. in few hours some photos of the rear installed.
