i actually looked to see if there was much room to do a secondary tank and run it piggyback in the fuel line. Seems real tight... im curious to see what others say.

As i live in belgium, a small small country with loads of gas stations I dont really feel the need of a bigger tank (big improvement of my st-50 i had anyway), but there are probably people up here that wanne see this bigger, to cruise arround longer! I'm following this, intresting stuff
Once people start doing mods their economy will go down, so adding a half gallon would be nice. If one were to remove the air box there would be room there. Honestly though I'm not sure if there would be enough people interested for it to be profitable for a company to develop such a product. If I were to do this I would see if there were a way to use the existing airbox as an auxiliary tank. Maybe add a liner or something.
I was also thinking that. I have an R1200GS and love it. I think Charlie Boorman and Ewan McGregor should do a remake of long way down or long way round, but this time on some GROM's. They could get some nice Touratech gear and some Zega pro side cases and be good to go.If i would mod my bike into this:

msx125 GS?
I'd def want a bigger tank, so i could go on and on!

Yes, I would like to see a larger fuel tank too. Perhaps 2 or 2.5 US gallons {9- 9.4 litres} or about 2 imperial gallons.
If anyone knows of a source or "retrofit" that works well please let me know.

There is tons of space under the "wing" panels. You could easily double the tank size under there, without disturbing the airbox.
However, I don't really think it's needed on such a bike. The 5.5 litres goes at least 200km which is usually measured in terms of x days city commuting, and anyway if you went on a longer trip then after that long in the saddle you're definitely going to want to stretch your legs out.

My concern is that one of the benefits of this bike is that it is lightweight and you really want to keep it that way. Adding a bigger tank will put a lot of extra weight at the top of the bike so it'll affect the handling of the bike as well as slow it down. I lost 8 pounds when I swapped out the stock exhaust, I don't want to gain that weight back and get some more mileage between fills. This isn't an off road bike so most people aren't going to need to worry about being stranded in the middle of nowhere. It's not big enough to really be able to take a long road trip and I don't see myself ever riding it more than 1 tanks worth before my back and butt is sore from riding and I could use a break anyways.
In conclusion, I don't see a need for it at least with what I use my Grom for and it would hurt what little performance this little bike has.

I'd love a bigger tank. I take my Grom on long enough drives where an extra half gallon would be welcome.
Ive had many motorcycles and after a windshield and Corbin seat.....it's great for traveling. It's much more comfortable than most of my classic motorcycles. The engine size only matters in a persons head.....or to a persons ego. IMO

On long trips I carry my 2 msr fuel bottles. I can carry an extra half gallon of fuel that way. I try to make my fuel stops around every 100 to 150 miles. I've only had to use them once on a 400 mile trip. Crazy head wind in one stretch dropped my speed and mpg way down.
I bought a 3 gallon fuel tank for my wrx (1 gallon extra) a few years ago to extend my range an extra 50% for touring. There might be room in the Grom's panels for an extra half gallon. For about 30% longer range.

I think a one piece unit that includes the the side shrouds/has them built into the tank would be great.
I have seen this done on several bikes including the DRZ-400
The side shrouds on the grom are big, its only a matter of time before a company makes a bigger tank
that also has the side shrouds included into its design as seen below

A bigger tank is needed after a 183cc or 209cc BBK to get back to stock mileage range
After all its just plastic and anyone with enough time can create a plastic mold from clay/wax to be taken to a company to perform the plastic pouring/cooling part of the liquid plastic It's not like there is any real "big" money in investing into making this aftermarket accessory become a reality

we were looking at the fuel tank the other night. it would be easy to add to the side of the existing one if oyu have sheet metal fabrication capabilities. especially below the seam, out on each side about 2". the problem with plastics is ethanol. some don't play well at ALL. The $2500 fuel tank on my ducati has seen its share of issues due to it. there was a class action suit against acerbis about it, that they lost. Its OK now but eh.

$2500 is a lot to spend on a fuel tank, for that much I could maybe buy a second hand sheet metal bender, welder, and take a sheet metal fabrication class on the weekend, and then have a skillset in my mind for life That is the most I have ever heard of anyone paying for a motorcycle fuel tank
Good idea about the tank, with all the plastic covering it I almost forgot its metal to begin with
For the most part labor/metal fabrication is cheap in Taiwan not as cheap as China but almost, and
quality here is better anyway, with this in mind I might take off the plastics and start putting cardboard
on to the tank to get all the space filled with cardboard
Then take to a shop where the can measure it/take a 3d picture of it/ print it 3d and what not
and finally expand the tank to those dimensions knowing good and well there will be no clearance
issues when mounted back on the bike
Custom metal tanks are common place among the chopper/harley companies
I think I have seen companies/builders offering one off fabricated metal tanks for the cheapest price
unpreped for paint and not smoothed out for about 500usd this is another option although price
but who knows with the right builder, and because of its size being very small (smaller then a chopper tank)
maybe you could even get it for 250usd with good negotiating skills?
again depends on the builder/shop/how busy they are
honestly I would fork over 250usd or even a little more for a custom bigger metal tank build by hand

yeah.. good luck building and fabricating a sport classic tank for 2500 buying the right equipment and learning to make it... not going to happen. the skill set is pretty intensive. Regardless....there is a company that makes an aluminum one for a lot, but its sweet as hell. Maybe in asia you could get this done but not in north america. Regardless, thats a complicated way to do it.. witht the modelling and such. Just measure it, make 2 sheet boxes for the sides of a stocker, weld them on and done. really not too hard, but i would def get a second tank to do it on. and then line it with some caswell to make sure it was all good. since its under bodywork it certianly doesnt have to be pretty.

Not sure about the U.S and other countries, in Canada a plastic gas tank is not street legal, for off roading only. Have a incident and the insurance company finds out the bike had a plastic tank and they will defiantly not pay. They may even give you a lot of headaches depending on the circumstance:money:

I would purchase a larger fuel tank if I could find one that surely fits...
and, I wonder if the Kawasaki KSR 110- or125 mini moto 7.3 liter [almost 2 US Gallon] tanks would fit.
KSR compared to MSX ...is a very similar mini moto .
In fact, they look almost like one may be a rebadged version of the other.
