690 R fuel solution
« on: January 22, 2019, 04:11:33 pm »
So I bought myself a 690 R the other day. I only realized what a problem the 12L fuel tank is when I planned my first trip. I already had the cheaper 5L fuel cans on me so I made a luggage plate to fit on the existing Toys to Go pannier racks and made the fuel holder to fit on top. Problem solved...

Cheers

Daredevil you!
Those 15 Liters will hammer the poor rack when landing or going through a ditch, hope for you it will hold.
We'll hear it no doubt  ;) :P

Second Burp's opinion re the weight and stress on the rear sub frame. Have seen too many riders with their rear sub frame adrift and threatening to drag in the dirt.
Bring the weight forward, you wont be sorry.

4 wheels move the body, two wheels move the soul.

Thanx for the comments, noted. This was basically a short term solution, i would either mount the fuel on the pannier brackets or use my 20L bladder on the rear seat.

Munger,

never mind 'bringing forward' or why, it's the hard-shell container that's the problem.
Same with hard luggage aka panniers, they hammer on the bike's frame - contrary to soft luggage/bags, which will 'spread out over time' the blows hence soften these loads.
Perhaps consider a (few) fuel bladder(s)?
Less volume too when empty.
I have two of the 3L type from Chris/FlyingBrick, they're decent things with plenty of eyelets for tying down, and they come with a pouring spout.
Even when tied flat on the back they'll soften the load transmitted to your bike because they deform/stretch a bit.

Your subframe is a plastic rotomould held by 4 (actually 3) bolts/points only.
Perhaps consider buying the uprated/better bolts for this?
I preach like I practice, got them too including the Toys2Go rack - with soft luggage mind!  :P

I agree with all that BurP has written, no subframe on that bike, just the 4 tank bolts (which themselves are often swapped out on OLDER 690s), so even carrying ONE hard fuel cell there would be risky, let alone say 20kg (15kg of fuel + weight of 3 containers + weight of through-bolt and holder...)


Where people have carried hardfuel cell/s (on a 690)with success is low down on a T2G rack, way further forward and way lower, and thus SUPPORTED.


Of interest, we do a 6L under-seat tank which then does not stress rear of bike, and THEN add say a 3L soft bladder for12L OEM tank +6L underseat + 3L bladder = 21L.


But I did like the LOOK of your solution; nice fabrication skills!  :thumleft:

My vote will also go for the 6L under seat tank and the 3L bladder from Flying Brick  if you need too have that range.  That should  get you 400km  before you run dry. Riding relatively hard I get 185km on a tank before fuel light comes on. Then you probably still have about 30km left.
With the fuel bladder and under seat tank you also keep the weight down a lot lower and when you have done 70km or so you can empty the fuel bladder into the tank and not have it take up space.

Munger, I missed that completely: my apologies, should teach me not to gloss over the text and drool over the pics!  :P
You're sorted then, it's a more gentle solution for your bike.

You clearly do not have Rade's ~6L tank which replaces your OEM airbox.
In case you want to know I can recommend this kit, one suddenly has almost 19L on board without seeing it.
You'll also get a washable good air filter (2 actually, one spare) plus more noise between your legs, addictive if anything  :thumleft:
