This is the Ken Block Tribute Helmet. 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. IN STOCK And ready to ship!!! $16.00 economy shipping within the lower 48 States. Thanks for looking!

Sizing: Size charts are recommendations from the manufacturer only. They are not a guarantee of a perfect fit. Each individual head is unique in both size & shape, and can alter proper fitting. The best way to get accurate fitting is to always try on the same helmet at a local shop. Each helmet manufacturer has their own unique shell size & shape and size chart, so just because you may wear a specific helmet size in one brand, does not mean that you will wear that same helmet size in a different brand. 1. Put the helmet on by grasping the chin strap in each hand and pulling it on over your ears until you feel the top portion of the helmet touch. If the helmet immediately feels too tight, i.e.; your head does not touch the top of the helmet, you cannot pull the helmet down over your ears, or is painful, try the next size larger. 2. Once you have found a helmet that feels comfortable and snug, you must assure that it is not too loose. To do so, with the chin strap securely fastened, grasp the helmet chin bar firmly with one hand and try to move the helmet from side to side and up and down. If the helmet slides on your skin and hair, it is too large. If your scalp and skin want to move with the helmet, the fit is snug. 3. Finally, while still grasping the chin bar, try to rotate the helmet as far down and forward as possible then as far backward as possible. If the helmet feels as if it might slide off in either direction, the helmet is either too big or the chin strap was not securely fastened. This manufacturer has a wide range of helmet sizes, but if for whatever reason you cannot find a helmet in this brand to fit your head size or shape securely, look into another brand. PLEASE NOTE: Our listing is size & color specific. The specific size & color is detailed in the listing. We are providing the manufacturer's recommended size chart for your convenience for fit. If the specific size in this listing may not be the best fit for you, please review our other listings for a size that may be of better fit.
