When I took the Cub away, I needed more than the little 1 gal tank that comes as standard - but there aren't a whole lot of aftermarket options (surprisingly:scooter:.)

So I got this made:

It upped my capacity to 3 gallons, or around 360 miles. Cheap and cheerful, it just required siphoning over when I ran dry. (See pipe at the back of the tank.) How many times did I manage to suck in a lungfull of fuel? Answers on the back of an arctic lorry please.

Looking to make something similar for my new CG, but with the girlfriend now occupying the back seat, I am struggling.

Struggling in the sense of where to put it?

Google Hartlepool Radiator company. They can weld a slice into a standard tank. No idea about the quality or service it was just one of the options I looked at. I gave up when I realised I'd have to cut my only tank (Bonneville tanks go for big £) and could a most add 3 litres. 3 litres on a CG is going to be a more positive step than on a Bonneville lugging a lump of Russian steel on the side I hope.

Thanks for that. 3 litres extra would be a big step forward from my current 12.

I've been looking into extending the tank myself, but I think I would rather find some way of attaching a fuel reservoir in front of the forks, over the mudguard. I think I can get a gallon there without putting too much stress on anything, and it gets the weight nicely forward. This is a biggie, as with a back box, panniers, and a girlfriend over or behind the rear axle, I want to get a little bit more weight over the front wheel.

I'm just waiting for a couple of parts from Honda, then we are going for a little test ride tomorrow, I will post some pictures showing whatever solution we work out. (If you can look beyond how ridiculous the whole set up looks!)

Two ideas:

Acerbis used to do a 2 litre squareish tank supposed to fit behind/replace the headlight on trail bikes.

Looking at these I thought they looked very very similar to the washer bottles used on vans and trucks, which are of course rather cheaper.

There should be loads of options for a bigger tank on a cg125. It's a narrow single tube frame so practically anything off a 70s or 80s jap bike will fit. Good thing about those steel tanks are you just beat them with a hammer if they foul on something a little bit. And if you can weld then there's no limit to what you can get on there.

I wouldn't fancy carrying proper weight infront of the headstock myself, I'd be paranoid about it interfering with the steering particularly when banked over on corners with liquid slopping about.
