This is my first post here-- to ask a question about chain life on these adventure bikes-- I am a street rider only on a bike with chain drive. I obsess about chain lubrication. I watch these videos of adventure riders riding through mud holes, sand dunes, grimy dirt-- and I can't imagine that a chain under those conditions could possibly last more than a couple thousand miles. I would think the grit and grime would literally chew up a chain in no time. What do adventure riders do about chain lubrication? Do they use some type of chain oiling system? I know a Scottoiler is considered the best, but I'm not paying that kind of money (I'm cheap). What do you consider the best chain oiling system? Or is just using aerosol spray the best?
