Spotted these, had no idea development was still being pursued for them:
And there are a few other designs out there. Interesting idea, I’ve always leaned in favor of them, but I think we need better-looking designs.
More contact patch is not a bad thing to have, especially when, if I lose traction on one tire on my M50, I’ve lost 50% of my total available traction.
Not something I’d replace a motorcycle with, but something I’d consider adding to the stable.
