I have a 10 tail pack so if that is 11 litres that should be plenty for around your waist. Kriega stuff is superb quality.
I've got one mate with an r3 and one with an r8, Si. Both love them. Both straight (acting, at least).
Sorry mate, thought you had an r11... kriega doesn't make the r11 anymore, but want a bigger waist pack than my oxford one... I've looked on eBay, but can't ring an r11.
Websites not taking orders mate, otherwise I would have ordered one last week.... cheers anyway sine.
all stockists are out of stock, as it's a discontinued item, but managed to source one from Pistonheads. 11 litres of arse bag, should be able to hold a bit!
