Just wondering who else would like to have a bigger steel fuel tank on their 939 Supersport either as an aftermarket part, genuine Ducati accessory or perhaps on the next model Supersport that would be compatible with the current 939 Supersport? If there was a small increase in size from 16 to 18 litres, balance, handling, looks etc wouldn't be significantly affected but the 939 would be a better sports tourer - you could comfortably fill up around the 300 km (187.5 miles) mark if you were gentle on the throttle and still have a few litres to spare and in its role as a sports bike for the road, you could fill up around 250 km when riding the bike harder. I had a 97 Supersport which had a 17 litre tank and after changing the carbs from Mikunis to 39mm Keihins, I used to fill up around 320 km which was great. However the low seat and high pegs gave me sore knees so I sold it. The 939 is far more comfortable for sports touring but a small increase in tank size would be welcome.
