A million years ago I had a CB160. I was too young to ride on the street so me and my hooligan friends would slam our bikes around a "track" we made in a cow pasture. It even included a jump or two. We forced our street machines beyond their intended purpose and ruined them within just a few months. But, they sure were capable of off road work. At least we claimed as much.actually no problem popping it up with the clutch, just can't find any good reasons to justify it. accelerating the wear & tear of the clutch plates, chain & sprockets in the process.
A few years later we realized we could smoke the crap out of Chevy Vegas and Ford Mavericks by forcing them to do brake burnouts. Even with automatic transmissions, with the right technique we could make them disappear in their own tire smoke inside 20 seconds or so. We killed those vehicles prematurely too.
My point... Often machinery can be pressed into service it's not designed to take, but at the cost of a short life. Our CB500's were designed to do a decent job at a bargain price. For that reason nothing about them is over-designed.
Sure they can wheelie. Just hope you guys fully disclose your riding habits to the next suck..., oops, buyer.
