If anybody is interested in banshee work this is the guy to talk to. And yes, its dave moore racing and not mp racing. I have been riding for 20 years and have used many so called race shops but this guy is the real deal. He builds swing arms, a-arms and does one hell of a job porting. And yes, this guy stands behind his work. Look him up at davemooreracing.com you won't be dissappointed.
