There's an Africa Queens tank available for the TA, both the new and old, as far as I recall. I've seen the AQ tank for the new 650TA, they're a very ordinary finish, made from fibreglass and bloody heavy WITHOUT fuel. About 4" of the fairing is cut away to make it fit, also requires the removal of the pulse air valve on the TA650. The owner of the bike I saw is still trying to find a suitable location for the airvalve, which prevents the engine from backfiring. Better would be a carbon fibre/kevlar mat mix for lighter weight. But at the price they charge for the fibreglass version I can't begin to imagine the cost for one in a better, lighter material. They do require a fuel pump, the Honda AT ( low pressure ) pump is best, pump that Africa Queens supplies has to high a pressure. At 38 litres capacity, it will take you a looong way The Honda AT tank also requires a fuel pump.
