I got one of those
nippy norman bottles that fit in the carbon canister space that adventure models have from 2008 on..
But i binned it as the screw top rubs against the frame and cuts it open with vibes.. so picked up a copy of sigg bottle for £7.00 500ml..at cotswolds lots better and cheaper than NN bottle..
If you crash and have a fracture, and oil leeks out that 500 ml could get you to help....you just don't know what can happen out on the road..
If you use it once...blalala you know the rest.
