Has anyone ever used a tank bag on an off road bike?
I ride off road on my trips and travel light with soft bags. My important stuff goes in a rucksack so I don't have to worry about taking it getting pinched. But getting older now and my shoulders are sore. I'm thinking of a tank bag? Good or bad idea for off road riders?
I used to ride with a Kriega 20 and or 30 rucksack, but like you, after a while it just turns out to be a pain. It's fine for smaller trips, touring or commuting - but everyday on a big trip - nope.
A tank bag is a good alternative, and I have ridden off road with one, they're not a problem so long as you get the right type of bag. So i'd certainly advise going for one with straps and definitely not a magnetic one. Bags that clip onto the fuel tank ring are also quite good, but it depends on which bike you're riding and if there's a ring for it. Either way, i'd still go for strapped.
This guide has more info on tank bags and some recommendations, might be helpful.
Hope this helps,
