I will take this up with you off-line.
We previously did make up some fender stickers as a fund raiser for one rider.
To use the gasgas name or logo on gear - you would need permission from gasgas corporate... Otherwise you are using their name/logo without their permission. Breaking the law and taking money out of their pocket...
We did previously make up some fender stickers and all of the profits were used to help a gasgas rider (and member here) with his expenses to attend the International Six Day Enduro.
To be honest - this wasn't a great experience for me.... A couple of checks bounced... And folks would only "donate" if they got something in return (when I made a request to the membership to help this guy out..). Didn't make me happy...
Thanks,
Jeff
