I joined the AMA eight years ago.
I have used their discounts to ship an RC51 from Baltimore to Houston, stay in hotels while riding cross country, buy parts for my bikes at discount, get into motorcycle shows at a discount, and used their roadside assistance twice to tow my broken bike home.
They also lobby Washington for all of us riders to fight ethanol in fuel, motorcycle only police check points, and all other anti-motorcycle legislation.
EVERYONE who rides should become an AMA member.
All the best.
