4sale: tesch TTTank4 for fuel or water
 

Never been used, not going to use them after all.... . Have a look at http://www.berndtesch.de
for pics, will sell for 250euro for two including the shutters...

From the website;

For the aluminum pannier TTTasche 4 you can buy an exta fitting aluminum-tank (only 2500 g. 1,5 mm). It fits exactly in the pannier on the inside of the bike. This means that the centre of gravity is close to the motorcycle. You can use this universal can for water or petrol! By this you can enlarge the store for fuel up to 20 liters (or 13 for water, 13 for petrol) ! By this you can solve for most motorcycles, especially the Japanese enduros, for which you do not find a larger fuel-tank, the fuel-problem riding long distances cheaply !!! The shutter is tight! No smsell in the box! This sloution is cheaper for all types of motorcycles as a large fuel-tank. These are are often hard to find or not available at all.

Because the TTTasche 4 and TTTank is more handmade they cost more than TTTaschen 1-3. But to buy this fuel-tank is much cheaper than to buy a large fuel-tank for your bike (if there exist one at all) ! This solution is very variabel: You can use the boy with or later without fuel-tank. If you put this tank into the box, the gravity point will be much deaper and some of the weight between the axes of the bike.
