I'll take first honors.<br /><br />A BMX helmet is probably good for a little kid on a small 50cc, not likely to see high speeds. However, I wouldn't even recommend a BMX helmet for somebody as old as 8 or 9 on an 80cc quad. They can easily reach speeds and possible impacts beyond what a BMX helmet is designed to handle. Lighter and less expensive equates to not as strong.<br /><br />I'm heavily into ATVs. The "250r" in my name refers to a legendary quad built by Honda back in 86-89, the full model number is TRX250R. I've built-up and raced many, I've even used nitrous oxide.<br /><br />We have a saying in the motorcycle and ATV community. If'n you got a $10 head, then buy a $10 helmet.Originally posted by KenImpZoom:<br />I know everybody will probably rag on me for this, but you can get a BMX style full face bicyle helmet for cheap and it offers good protection. It has a hard plastic shell just like a motorcycle helmet. <br />
