DR650 tank sizes?

[Squiggles]

At first this seems like a screwed up question.. but nobodys been able to give a straight answer yet
Imperial Gallons (4.5L/gal) vs US Gallons (3.75L/gal)

So a Stock DR650 Tank is what, 13L? i.e. Roughly 3.4US Gallons

What about the aftermarket tanks?
A Clarke 3.7"Gal" is 13.9L (US conversion) or 16.7L (Imperial conversion)
An IMS 4.9"Gal" is either 18.4L or 22L

So IMS owners, is your 4.9Gal 22L or 18.5?

Try US gals giving 18.5l when new but expanding to about 20l with a bit of use in hot weather and a full fuel load. The tanks don't pressureise just the weight of the fuel in warm weather makes them expand. If you want to put hot water in them and apply some pressure with a bike pump you can probably get 22l in it.

iIf your looking at the auction on tardeme here that is definatly an IMS tank that he would most likely have brought from Just Gas Tanks in the states. The IMS tanks seem to be pretty robust and stood up well for the 8k kms I had one till I sold the bike. Buy now is pretty good given current exchange rates.
Only thing you might want to get is a new O ring for the fuel tap as they one that IMS ships them with is a little thin. Cost you all of $1.

Hope you're right, all my research shows the clarkes are more pointed at the front where the IMS bulges, which makes it an IMS, and the guy has presumably only ever filled 17L so doesnt know better

18.5L
Mine gets 19.4L in from veeeerrrry empty and it's about 8 years old (60,000km).
I think lately IMS have been doing better o-rings than in the past.

I liked that auction. The answers to the questions were fun
