I bought this Suzuki bike secondhand and was surprised to see it still comes with tubed tires. I didn't expect it since the bike is marketed for adventure riding. With how easy tubeless setups are to plug and how much safer they are when punctured, it just seems outdated... Any reason Suzuki (and a few others like Yamaha I think) are still sticking with tubes on front 21" setups? Is it a cost thing?
