Ken was a professional rally driver, business visionary, and motorsports legend who held many passions in the powersports industry - including snowmobiling. Ken and 509 were partnering on the development of the KB43VER™ 2.0 Limited-Edition Helmet and finalizing design just months before his passing in 2023.  

Plans to launch the KB43VER™ Altitude 2.0 Limited-Edition Helmet resumed in 2024 with the Block family’s decision to connect his visionary projects with the social good he created through 43i. A portion of the sales from the helmet will go to 43i’s youth programs, including Project Brain Bucket. This program aims to promote helmet safety among young riders through education about the brain.
