the 26 ounce would be a better size capacity wise

Mines under the seat as well... not had any problems or noticed any extra heat. Even got room for a small bit of ply for under the sidestand ... when the grass is wet .. along with the foam to keep the tank upright.
Here is what I did. The tank is a stainless steel waterbottle with the cap modified (drilled so that the hoses are a snug fit through the cap.) You do not need a bottom tap on the tank. And the tank can be quite small and still work just fine. Overfill the tank and the first time the radiator cap vents it will push any extra coolant out the vent tube and to the ground under the bike. If you need to refill after that, you have a coolant leak either internally (headgasket) or externally. The tank can be mounted on the other side just as well if you have an accessory tap on the side shown.

Wayne - Ever tried Evans Coolant? - In theory this would eliminate the need to have the bottle as it's waterless and DOES NOT expand. Home » Engine Cooling Systems
I'm looking to give it a go at the end of this season when I change the coolant etc.

Yes.
Evans is pure EG coolant. It doesn't absorb/carry as much heat as water. So you really need to overdrive the water pump to increase flow. While possible on the R3, the stock pump cavitates above 4000 rpm, so no real gain there.
DEI makes a great product called Radiator Relief that works like Redline's Water Wetter (but much better)- a surfactant that breaks down the coolant's surface tension, and helps cool better. Add 1/3 of a bottle to a 30% mix of PG or EG coolant and water, and it is hard to beat. This will still prevent freezing down to about 15°-20°F. We use DEI RR in pure water for race and track bikes.
I have tested many ethylene and poluethylene glycol (EG and PG) coolants, as well as modern organic acid technology (OAT) coolants. And have never really seen a difference - even heavily loaded on the dyno. DEI RR helps cooling and helps to cool back down more quickly when added to most all coolant mixes. Use the least amount of antifreeze required for freeze protection. The more water, the better cooling efficiency.

Aha - And MUCH MUCH CHEAPER. Now to find it somewhere in the EU.

You should be able to find it in the EU, contact DEI and see if they have a distributor in Europe. If not, let me know, and I can ship you a bottle. Shipping costs to the EU has gotten crazy this year, but I will see what we can do for you.

Several in the UK. I'll can maybe get it sent to my parents in the UK and collect when I'm there on hol's. Postage is a swine inside the EU too.

I Like that idea!!! But I would put it in the air box
